    Grounding energy: how to scale cloud computing and data centres with Cerio

    When we say 'the cloud' what we mean is 'the data centre'. Globally, data centres are projected to consume over 1000 terawatt hours in 2026. What does that mean for energy production, distribution, and consumption? Guest Phil Harris, Cerio President and CEO, joins thinkenergy to shed light on something we all rely on but may not fully understand. From efficiency to sustainability, environmental concerns to Cerio's role improving how data centres manage energy. Listen in for the future of cloud computing.  - Related links  ●       Cerio: https://www.cerio.ai/ ●       Phil Harris on LinkedIn: https://www.linkedin.com/in/paharris/  ●       Trevor Freeman on LinkedIn: https://www.linkedin.com/in/trevor-freeman-p-eng-8b612114  ●       Hydro Ottawa: https://hydroottawa.com/en     To subscribe using Apple Podcasts: https://podcasts.apple.com/us/podcast/thinkenergy/id1465129405 To subscribe using Spotify: https://open.spotify.com/show/7wFz7rdR8Gq3f2WOafjxpl To subscribe on Libsyn: http://thinkenergy.libsyn.com/ --- Subscribe so you don't miss a video: https://www.youtube.com/user/hydroottawalimited Follow along on Instagram: https://www.instagram.com/hydroottawa Stay in the know on Facebook: https://www.facebook.com/HydroOttawa Keep up with the posts on X: https://twitter.com/thinkenergypod --- Transcript: Trevor Freeman  00:07 Welcome to think energy, a podcast that dives into the fast, changing world of energy through conversations with industry leaders, innovators and people on the front lines of the energy transition. Join me, Trevor Freeman, as I explore the traditional, unconventional and up and coming facets of the energy industry. If you have any thoughts, feedback or ideas for topics we should cover, please reach out to us at thinkenergy@hydroottawa.com. Hi everyone, and welcome back. Data centres have come up a number of times on this show, and for very good reason, they have become a key underpinning technology for so much of our lives, every time we pull out that phone from our pockets to pull up directions or buy something online or doom, scroll on your social media or new site of choice, every time you use your phone stream a movie, leverage an AI model, whatever you end up using it for, it's funny as I read this list, I'm sure there's like some university student out there who's thinking, man, what is this old man talking about? We don't use our phones for that, whatever the kids are doing these days, whatever we're doing these days with our phones, with our computers, our tablets, et cetera. All of that leverages infrastructure that most of us have never seen and, quite frankly, probably don't really understand we talk about the cloud like it's this amorphous, nebulous thing, but in reality, we're talking about real hardware in a real building that uses real energy, mainly electricity, a lot of water. And this isn't really new, like we've been leveraging centralized data centres for many years now, but what is changing is the scale of the data centres that we're seeing now, and the pace of growth in computing power that we need to do, the things that we want to do, and that our data centres are able to deliver. So just to throw a few numbers at it, the traditional data centre servers that maybe power the early days of on demand online streaming services, for example, they used anywhere from five to 15 kilowatts per rack. But modern server racks that are used to power AI searches, for example, can hit anywhere from 60 to 100 kilowatts per rack. This is great from a power output per rack perspective, but it means massive energy needs, and that is showing up in the size of load requests that we're seeing from new data centres. New data centres today are asking for service connections that are orders of magnitude higher than those built even just five years ago, globally, data centres are projected to consume over 1000 terawatts in 2026 or terawatt hours, sorry, in 2026 and just a quick kind of refresher from high school or wherever you would have learned this, a terawatt is 1000 gigawatts, which is 1000 megawatts. So 1000 terawatt hours, which is roughly equivalent to the annual electricity demand from the country of Japan, an entire country. So given all of this, there are a lot of incentives to find ways to maximize efficiency and reduce some of that energy demand, and that's where my next guest, Phil Harris and his company Cerio come into play. I'll let Phil get into the details of exactly what Cerio does, but essentially, their goal is to reimagine the data centre to maximize sustainability and reduce energy needs. Phil is Cerio's President and CEO, and has been in the networking and data centre industry for over 35 years, including at well known companies like Intel and Cisco. And I'm really excited about this conversation. One to understand, how do we make data centres a little bit more efficient, or maybe a lot more efficient, but also just to really understand, like, what are we talking about when we talk about a data centre? What is actually happening, what is physically inside these buildings, and we'll get into a little bit of that in our conversation. So Phil, welcome to the show.   Phil Harris  04:13 Well, thanks, Trevor. I appreciate it.   Trevor Freeman  04:13 So Phil, obviously we're here today to talk about your work building sustainable data centres, or trying to make data centres a little bit more sustainable. But before we get into that. You know, you've spent your career, you know, decades of your career at different tech giants. Let's call them in telecisco to to mention, you've seen quite a bit of change. No doubt, over your time, has that changed, like, does this industry change linearly? Does it grow fairly steady, or is it kind of big jumps? And are we on the cusp of any major shifts? What can you kind of tell us about the future of this, this sector, data, tech, etc?   Phil Harris  04:48 It's interesting, I think, as companies start, and I was at companies like Cisco, for example, when it was a very small company to when it was very large company. And this should be no surprise for anybody, the bigger the company gets, the harder. It is to change, and they really find that the only way they change is when they absolutely have to, not because they want to, and that's a combination of just inertia and shareholders expectations and a whole bunch of things. So I would say that the bigger the company is, the harder is them, for them to react. And so I think small, nimble companies tend to do much better when there's a lot of transformational technology and development and changes in the overall ecosystem we live in. I think just the second part of your question, you know, I look at the current situation as a point in time where a lot of companies will have to make some significant changes, simply because we're hitting too many walls, technological walls, commercial walls, geopolitical walls, that are really sort of confining what people can do. So I think what's going to about to happen is we're about to see a significant change, and this is not atypical in the industry. If we think about back into the into the start of what we would think of today as computer science around mainframes that were happening in the 60s. You know, for about a decade and a half, two decades, there was a lot of dominance around a particular way of doing things. And then some new innovational technology came along that rapidly changed, that scaled out, and it went from a very dominant set of players to a much larger number of smaller players who could then provide more innovation and more scale and more choice. And I think we're about to see that transition occurring as well.   Trevor Freeman  06:25 So is this, is there sort of like an analogous time, 10 years ago, 20 years ago? Are we on the cusp of, like, the big, the big change that we've seen before? Like, what would you compare this to? You know, in the last 2030, years?   Phil Harris  06:40 Yeah. I mean, I think there's been eras of compute. And if we say, I mean, we can find analogies outside of the compute world, but let's just stay in the compute, computing science world. I gave the mainframe example as one, and then we went to what we call client server, which scaled out rapidly. Telephony. We went from large, big telephone exchanges that started in in the government space, went to very large organizations. Now, basically we've completely scaled out how we make phone calls to use that now 20th century as a terminology. Nobody really makes telephone calls anymore. And we went through this with cloud computing and the Internet, where there was a change in the approach to the way we did things that suddenly gave us a scale out mentality, rather than a scale up mentality. And I think that's what we have to key in on here. Is it that we can take some of you? I was on a panel yesterday where we were talking about scale, and I say, well, to scale or not to scale? That is not the question. It's how do we scale? Do we continue to scale up, which is the current model, or do we start to think about scaling out, which is a more distributed model? So we go from a small number of big things to a large number of smaller things. And typically in computer science, whatever you want to start, storage, compute, memory, telephony, everything we've ever done goes through this arc.   Trevor Freeman  07:59 Yeah, it's it's interesting, and it's, there's obviously my brain's gonna immediately try and find those, those similarities between my world that I live in on the energy side of things. And it's the same question, like, there, there's, there is no path where we're not expanding the amount of energy we need. We're not going to be using more energy. But there are different ways to do that, and there are different paths we can take the business as

    The future of energy from the view of a next-gen energy professional

    How are we preparing the next generation of energy professionals? Kieran Graham, student of the Sustainable and Renewable Energy Engineering program at Carleton University, is set to embark on his career in the energy sector. Kieran joins thinkenergy to chat about his studies, from thermodynamics to power generation, regulatory to economic aspects, and what's on the horizon for the industry and his future. Listen in for a fresh perspective on the future of energy with a next-gen energy professional. Related links: Sustainable and Renewable Energy Engineering program, Carleton University: https://admissions.carleton.ca/programs/sustainable-and-renewable-energy-engineering/ APEX Lab, Carleton University: https://carleton.ca/apex/ Kieran Graham on LinkedIn: https://www.linkedin.com/in/kierangraham1/ Trevor Freeman on LinkedIn: https://www.linkedin.com/in/trevor-freeman-p-eng-8b612114 Hydro Ottawa: https://hydroottawa.com/en To subscribe using Apple Podcasts: https://podcasts.apple.com/us/podcast/thinkenergy/id1465129405 To subscribe using Spotify: https://open.spotify.com/show/7wFz7rdR8Gq3f2WOafjxpl To subscribe on Libsyn: http://thinkenergy.libsyn.com/  - Transcript: Trevor Freeman  00:07 Welcome to thinkenergy, a podcast that dives into the fast, changing world of energy through conversations with industry leaders, innovators and people on the front lines of the energy transition. Join me, Trevor Freeman, as I explore the traditional, unconventional and up and coming facets of the energy industry. If you have any thoughts, feedback or ideas for topics we should cover, please reach out to us at think energy at hydro ottawa.com, hi everyone and welcome back. We know that we are already in this period of change that we call the energy transition, but this is not a short term thing. We will be in this period of change for years and likely decades to come. And that means that the next generation of energy professionals, so engineers, policy experts, customer focused, people, finance and so on and so on, they might spend their entire careers working on this. So I thought it would be interesting to check in with someone who's just about to enter the workforce to find out how we're preparing that next generation to dive head first into this challenge and hopefully bring innovative and exciting solutions to the table. This is a career and society defining challenge. This is something that we'll be focusing on for many, many years to come. So I really wanted to understand what is that next generation learning. Now I'm sure you'd all agree that what you learn in your formal schooling is only one small part of the knowledge base and skill set that is important for contributing in a meaningful way. I know that the things I became really excited about and passionate about as I was getting through my engineering degree really helped set my course and have led me to where I am today, and definitely was not the course I thought I was on when I started engineering school. And for the record, these things that I became really passionate exciting about weren't, you know, the fluid dynamics and soil mechanics and thermodynamics and all these courses I was taking. It was the concepts and the way of thinking and the things I became passionate about. So all that being said, I'm pretty excited today to talk to my guests about what he has been learning and how he thinks that's setting him up for a career focused on energy. Kieran Graham is in his final year of his degree at Carleton University here in Ottawa, and he's in the sustainable and renewable energy engineering program. I love the fact that we have a whole focus program on clean and renewable energy, that's fantastic. Kieran is the president of the Sustainable and Renewable Engineering Society, and he helps organize academic social and networking events for students in that program and others that are interested in sustainable and renewable energy. He has worked with the apex lab at Carleton, doing research on various carbon capture technologies, and he was also the organizer, or one of the organizers, for the 2026 Ontario Engineering Competition. Kieran Graham, welcome to the show.   Kieran Graham  02:48 Thanks a lot for having me. I'm excited.   Trevor Freeman  02:50 So Kieran, let's start with a little bit of background on your program at University. So you're in the Sustainable and Renewable Energy Engineering program at Carleton University. Tell us a little bit about what that program is and what you focus on.   Kieran Graham  03:03 Yeah, so I will admit it's a little confusing at first, like Sustainable and Renewable Energy Engineering, the long name, and then we have two streams. So one's called Smart Technologies for Power Generation Distribution, the other one's about efficient energy conversion. So the easiest way to actually differentiate these two is electrical and mechanical. So smart technologies is electrical efficient conversion is a more mechanical. So like, if you have know anything about engineering disciplines, it's electrical and mechanical.   Trevor Freeman  03:35 Gotcha   Kieran Graham  03:36 Also, by the way, SREE is short form for sustainable renewable energy engineering, just to save us some fumbling over our words, in the future, perfect.   Trevor Freeman  03:45 This is a very acronym heavy podcast at time, so I appreciate you spelling that out for us. So when we when we hear SREE, you're talking about the program, gotcha. So give us an idea of, like, what's the focus of the program more broadly?   Kieran Graham  03:58 Yeah, so like, I'm in the electrical stream. So I take a lot of different courses at the beginning, ranging from fluid mechanics, and we take electrical courses like circuits and signals and just Electronics One. But then we also later take courses that are more SREE specific, that are more focused on learning how we are using thermodynamics to then put it through as a turbine and then create that energy. And then, how is it work, specifically with a nuclear power plant, or we even learn a little bit about natural gas, but just for context. And then, how does that differ from generating electricity with wind in a wind turbine. It's pretty similar, but like, how where's the difference? And like, how do we apply that in different scenarios?   Trevor Freeman  04:48 Got you so if I could say that back to you. You know, when I was in energy or engineering school, I learned a lot about those fundamentals. I learned, we know, we did thermodynamics, we did all that kind. Of stuff we just mentioned, but the application to power generation, and the renewable aspect of it, the sustainability side, that was all stuff I learned later in my career. You're building that into your programs. Kind of built that into what you're learning. So you're learning the more traditional engineering side of things, the thermodynamics and how this stuff works, but in the context of power generation, I assume, you know, like application of power generation, like how the grid works, things like that.   Kieran Graham  05:28 Yeah, exactly. So we take a little bits of courses that other programs will take, and then I got, first we're taking those same courses, and then we take other courses that are really specific, and we apply them to sustainable and renewable energy engineering. The other thing is, later in our degree, we also apply things on a more higher level, like energy is kind of like a high level topic. There's so many things that are happening and there's a lot of regulatory and economic aspects to it. So we have to look at, like, the energy market and like, yes, like nuclear fusion is like a great option if it works and if it's economically viable. And you know, nuclear has its own regulatory aspect, so we have that coverage of information and knowledge later in the years.   Trevor Freeman  06:17 Gotcha so. And for our listeners out there who are not kind of engineering nerds like Kieran and I. One of the things how I describe engineering more broadly is that it's sort of a systems thinking approach to things. So understanding, what are my inputs? What's the result of those inputs? What does that mean for the output? What are the feedback loops? And so what I'm hearing you say, Kieran, is that it's bringing that into the energy sector, the energy industry, which is fantastic, like, really exciting to hear that this is, this is what you're learning, and this is what the next sort of generation of engineers is being taught right now. How did you end up in this program? What drew you to this particular field of engineering?   Kieran Graham  07:01 Yeah, so it's a little complicated, because when I applied to university, I knew I wanted to stay in Ottawa, and my parents both went to Carleton. My grandpa worked at Carleton like when it was first established, so I had deep roots there. And in my mind, Carleton is a superior University in Ottawa. I know that's controversial, but, you know, it's okay. But anyways, I applied to three different engineerings at Carleton, and my first choice was actually aerospace engineering, because in high school, it was kind of like a this was the prestige of making aerospace engineering. And I actually got in and my first year I was in aerospace engineering, but at Carleton, first year, engineering is all general. So after first year, I decided that my goals, and I don't want to talk down to my aerospace colleagues, but my morals and my aspirations were more set towards a sustainable and renewable energy engineering focus. So sustainable renewable energy engineering was my second choice going into Carleton, so it's a pretty easy switch in second year, but from my childhood, I had an aunt who worked for Greenpeace Canada and also just learning about sustainability in my house and at school, this just

    Talking trees with Overstory: helping utilities trim with power

    Trees are a major cause of power outages. They're also a wildfire risk—when branches hit a conductor, a small spark can become a big blaze. Lynn Petesch of Overstory joins thinkenergy to talk trees, exploring how AI, satellite imagery, and vegetation intelligence help utilities prevent outages and reduce wildfire threats. Including Hydro Ottawa, who saw a 44% drop in tree-related outages since partnering with Overstory. Listen in for how we work together to keep the grid safe in an era of extreme weather.   Related links  Overstory: https://www.overstory.com/ Lynn Petesch on LinkedIn: https://www.linkedin.com/in/lynnpetesch/  Trevor Freeman on LinkedIn: https://www.linkedin.com/in/trevor-freeman-p-eng-8b612114  Hydro Ottawa: https://hydroottawa.com/en    To subscribe using Apple Podcasts:  https://podcasts.apple.com/us/podcast/thinkenergy/id1465129405   To subscribe using Spotify: https://open.spotify.com/show/7wFz7rdR8Gq3f2WOafjxpl   To subscribe on Libsyn: http://thinkenergy.libsyn.com/ --- Subscribe so you don't miss a video: https://www.youtube.com/user/hydroottawalimited Follow along on Instagram: https://www.instagram.com/hydroottawa Stay in the know on Facebook: https://www.facebook.com/HydroOttawa Keep up with the posts on X: https://twitter.com/thinkenergypod ----- Transcript: Welcome to thinkenergy, a podcast that dives into the fast, changing world of energy through conversations with industry leaders, innovators and people on the front lines of the energy transition. Join me, Trevor Freeman, as I explore the traditional, unconventional and up and coming facets of the energy industry. If you have any thoughts, feedback or ideas for topics we should cover, please reach out to us at thinkenergy@hydroottawa.com, Hi everyone. Welcome back. Today on thinkenergy, we're going to be talking about trees. Yes, you heard that correctly. Trees. I know this is a show about energy, but there's actually a very real connection between our electricity grid and those slow growing, majestic givers of shade, lumber, fruit and so many more benefits. Honestly, who doesn't love trees? But I'm not just kicking this episode off in my capacity as a tree hugger. Let's take a look at this through a utility lens, and I will use Hydro Ottawa as an example. Hydro Ottawa service territory includes some very rural and very forested areas. Even our urban territory has a fairly extensive tree canopy. As a result, Hydro Ottawa trims about 60,000 trees each year. Why? Because trees contracting power infrastructure is a big problem. Tree interference remains a leading cause of power outages for us. Strong winds force them onto our wires. Heavy snow or freezing rain builds up and weighs down branches, breaks limbs, and increases the risk that part of a tree may touch a line, and in some extreme cases, heavy storms can even send trees or branches crashing into our poles, damaging the poles. The struggle between power lines and trees, which, again, don't get me wrong, we all love trees, has been going on for years. There is a constant struggle between trimming enough and getting the right trees trimmed and maintaining as much tree coverage as we can. In 2022 we identified a disruptor in this dance, the solution came through a partnership with Overstory, a company that uses satellite imagery, infrared technology and artificial intelligence to help utilities manage vegetation and trim trees more efficiently. And the timing could not have been better. Just days after we started working with Overstory in the spring of 2022 the derecho hit Ottawa. Our Ottawa based listeners will remember this storm well. It was monumental in the history of our city, and indeed for us as utility, winds reached 190 kilometers an hour. For our non-metric listeners, that's nearly 120 miles per hour. The storm ripped through poles houses and cause considerable damage to our city's urban forests. Overstory played a crucial role during the cleanup and in helping us level up our vegetation management strategies moving forward, we realized that the insights we got from Overstory would help improve our proactive approach to tree encroachment and hazard identification, and this is essential in this era of extreme weather events. We know that climate change is causing more frequent and more extreme weather events. According to Climate Central, the number of weather related power outages in the United States increased by 78% between 2011 and 2021 and severe weather accounted for over 1000 outages across Nova Scotia just in the year of 2024 we want to keep you connected during these heavy storms, and that's why we're looking to organizations like Overstory. So what does Overstory do to help us keep the lights on? Well, without giving away too much, because we're going to get into the details shortly, Overstory through a detailed analysis of the scans they do of our entire grid, identifies high risk areas, which we can then prioritize and better focus our resources when it comes to vegetation management, this level of monitoring and focus reduces the risk of trees from coming into contact with our poles and disrupting Your connection to the grid, the results speak for themselves. Since partnering with Overstory, we've reduced vegetation related outages by 44% and that's only part of the story, as we'll discuss further, Overstory also plays a crucial role in helping utilities prevent wildfires in high risk areas across North America, similar to extreme weather, wildfire frequency and intensity is also increasing, in part due to climate change expanding cities and many other factors. And when wildfires do happen, these stories are heartbreaking. What many people don't realize is that lots of wildfires are sparked by trees making contact with power lines, and that is why Overstory plays a key role in tagging areas where those fires are most likely to ignite and spread, making it easier for utilities to prioritize trimming work and vegetation management in those areas. To dive more into how Overstory is helping us here at Hydro Ottawa and. And other utilities helping us identify and act to mitigate risk associated with vegetation. I'm really excited to have Lynn Petesch on the show today. Lynn is Overstory's, Head of Customer Success, and has spent the past 10 years building customer facing teams with a specific focus on technologies that tackle the climate crisis. She began her career working for the United Nations and the diplomatic service of her home country, Luxembourg, before moving into the tech sector to really work in environments where she could drive impact more quickly and at greater scale. Lynn Petesch, welcome to the show.   Lynn Petesch  05:34 Thank you. Thanks for having me.   Trevor Freeman  05:36 Okay, so let's start at the very top with a high level look at what Overstory does and how the organization came to be.   Lynn Petesch  05:45 Yeah, let me tell you about Overstory. I mean, we are a vegetation intelligence platform. We use remote sensing and AI to give electric utilities, including Hydro Ottawa and others, a clear, system wide view of their risk. They always do it because they want to address three things, or sometimes more, but kind of, there's always a few goal posts, and it's either improving reliability, reducing wildfire risk, if that is if they're in an area where there is a concern, and or improving operational efficiencies. So Overstory very much becomes a decision-making tool for their programs were used mostly by the vegetation management people, operations people, wildfire mitigation teams, and they each time they want to either use a program that exists, prioritize it, reshape their work. They might be preparing for storm. They might be working on a wildfire mitigation risk so the company, more broadly, was founded in 2018 by Anniek Schouten and Indra den Bakker. This was back in the Netherlands, and they were leveraging, or getting really interested in satellite imagery, and were very initially using it for deforestation purposes. So, the climate resilience DNA has always been with us. But like any startup, we were looking at that kind of target audience that was most interested in what we had to offer. And pretty quickly, we landed on the electric utilities. They had the most pressing need to use remote sensing at scale to solve very big problems, honestly. And so we pivoted into that space of electric utilities, and then in 2020 Fiona Spruill, who's our CEO right now, she joined us. She shaped the company into what it is today, and that is really around building safer and more reliable operations.   Trevor Freeman  07:33 That's great, and I want to dive into some of the details. Our listeners will know that we talk a lot about grid modernization here and talk a lot about better intelligence of what's happening on the grid in all aspects, and something we haven't really talked about, and I'm excited to talk to you about today is the sort of vegetation management side of it. So really excited to get into the details. But before we do that, I'm always really curious to understand, you know, the people behind the conversations. How did you get into this area of, you know, high tech vegetation management? I touched a little bit on your bio in the intro, but give us a sense of, you know, how did Lynn come to be in the space that you're in right now?   Lynn Petesch  08:12 Yeah, I wouldn't say I grew up thinking I was going to work in this space, but I love working in it now. So actually, right out of college, I went to work for the United Nations, but then in the last 15 years, I started working at high growth tech companies, startups, and I've always been focused on leading and building CS operations, which is basically the customer success teams. They're the ones that are in front of the customers, implementing these software programs, kind of working very

    thinkenergy shorts: what's in store for Canada's energy sector in 2026?

    It's a new year, so we're unpacking what 2026 could bring for Canada's energy sector. Host Trevor looks back at 2025, from shifting federal policy to rapid AI adoption. Then he scans the horizon: faster major project approvals, an east–west grid push, and new hydro and small modular reactor investments in Ontario. He also touches on AI-powered DER programs, battery storage, and wider support for industrial decarbonization. Plus a quick note on the podcast's new pace.   Related links   ●       Independent Electricity Systems Operator (IESO): https://www.ieso.ca/    ●       Save on Energy program: https://www.saveonenergy.ca/   ●       Trevor Freeman on LinkedIn: https://www.linkedin.com/in/trevor-freeman-p-eng-8b612114   ●       Hydro Ottawa: https://hydroottawa.com/en     To subscribe using Apple Podcasts: https://podcasts.apple.com/us/podcast/thinkenergy/id1465129405    To subscribe using Spotify: https://open.spotify.com/show/7wFz7rdR8Gq3f2WOafjxpl    To subscribe on Libsyn: http://thinkenergy.libsyn.com/  --- Subscribe so you don't miss a video: https://www.youtube.com/user/hydroottawalimited Follow along on Instagram: https://www.instagram.com/hydroottawa  Stay in the know on Facebook: https://www.facebook.com/HydroOttawa  Keep up with the posts on X: https://twitter.com/thinkenergypod --- Transcript: Trevor Freeman  00:00 Welcome to a thinkenergy short hosted by me, Trevor Freeman. This is a bite sized episode designed to be a quick summary of a specific topic or idea related to the world of energy. This is meant to round out our collective understanding of the energy sector, and will complement our normal guest interview episodes. Thanks for joining and happy listening. Hi everyone, and welcome back and Happy New Year. Welcome to 2026 this is the first think energy podcast episode of this new year. Happy to be here with you. I'm your host, Trevor Freeman. So last year, we started off 2025 with a little bit of a look forward at some of the energy stories we might see throughout the year. And I think this goes without saying, 2025 was a pretty eventful year when it comes to energy and politics and all things associated with that certainly had lots of twists and turns, more than any of us expected. But I kind of think that's just the new normal in all things this during this time of history, but certainly when it comes to energy as well, I think we should just expect every year to be unexpected, lots of twists and turns. So I think the best way to start this one is to look back at some of the things we said we were keeping our eye on at the beginning of last year and see how they turned out, and see whether or not our predictions or guesses were correct and kind of what happened throughout the year. So just for a little bit of context, when we recorded this episode last year, Justin Trudeau, Canada's Prime Minister at the time, had just resigned the leadership of the party and as prime minister. So we knew that a new leader was coming for the Liberal Party, and likely a federal election was on the horizon. And at the time, the Conservative Party in Canada was much more popular with voters according to polls, and it looked very much like there would be a new government, a new federal government, but that is not what happened. And I'm sure Canadians will know that is not what happened. So after Justin Trudeau resigned, the liberals climbed in the polls. They chose Mark Carney to lead them, and not long after they won the election. Now in the episode last year, I had said that should the Liberals stay in power, which seemed like a long shot at the time, but should the Liberals stay in power? We knew what their energy policy was. They would keep the carbon the price on carbon. They would invest, continue to invest, in clean energy infrastructure and continue working towards their net zero goals. They had been working on that that was kind of a main pillar of the liberal party's approach to governing, and that felt like a safe bet. But even that did not come to pass. On his first day in office, Mark Carney canceled the price on carbon, and soon after that, he paused the previous government's EV target, or target to achieve certain sales on electric vehicles, and just recently, he has signed an MOU to work with Alberta on a new bitumen pipeline. So that is a little bit different than what we expected, should a Liberal government continue? So why is all this happening? Well, this, this isn't a politics podcast, so we're not going to get into all the specifics, but plainly stated, the government is saying they want to position Canada as a leader, both in clean energy, but also economically. And there are some economic pressures that the government is under, and this is what they are saying that is the best way to move forward in that so we'll get to some of the outlook on the new government, or not so new anymore government, but the current government shortly. But let's have a look at some of the other things that we said might happen for 2025 last year, we noted that utility companies would likely continue to use AI to streamline their processes and monitor infrastructure and just really take more advantage of AI. Personally, I can say that AI has moved forward in ways that we couldn't even predict last year, at least that, you know I couldn't predict last year. I'm sure there's folks out there who totally saw where this saw where this was going, but AI really is taking off in our personal lives, certainly in the workspace and definitely in the utility space as well. So we saw some of that come true, but we also see that AI is capable of way more than that in the energy sector, like all sectors of the economy and all areas of society are really looking at new ways to use AI and figure out what's the best way to integrate this into our business. How do we take this from pilot projects to, you know, actual core parts of our business? So that's continuing for sure. We also said that electricity companies or utility companies would continue to invest in. Grid modernization, and that certainly is happening. In August of 2025 the federal government announced a plan to spend over $13 million to update Ontario's power grid, with five major projects on the horizon, which is a huge investment, and investment of this size is really intended to make the system more reliable and help manage projected electricity demand. And you know the other thing, and I'm sure I've talked about this before on other episodes, so you'll be aware that hydro Ottawa is still in the in the process of getting approval for our next five-year plan, which has big investment in reliability and modernization and supporting continued electrification. And of course, we talked a little bit about the trade conflicts with the US, and you know how Canada is responding to that. And certainly, that was a major piece of 2025 it really formed a lot of the policy, or influenced a lot of the policy of both our federal government as well as provincial government when it comes to energy projects, it's increasing that look kind of east to west, rather than north to south. So making sure that we have good interprovincial energy cooperation and collaboration. And certainly, we've saw some progress on that throughout 2025 so on the sort of provincial side of politics, again, I'm in Ontario here, so we had suggested that we would likely see a provincial election in 2025 and certainly that's exactly what happened. The Ontario Conservative Party won another mandate, and part of their approach since they've come back into power, or one that new mandate is to look to expand clean energy, look to expand our nuclear fleet in particular. And we'll talk a little bit more about this in a little bit. So that's kind of a summary of the 2025 outlook that we did a year ago. Now let's get into what might we see moving forward in 2026 and again, you know, just the caveat here, this isn't a politics podcast. This is strictly about energy. So going to try not to weigh in on one side or the other of some of these issues, just highlighting what we might see moving forward. So, first off, major projects. So in 2025, this sort of newly elected Prime Minister of Canada, Mark Carney, founded the major projects office. This department looks to streamline the approval process for what they consider nation building projects. You know, trying to help take the approval process for those projects to be like a two-year decision rather than a five year decision under that kind of previous process that it went through. On the website for this the Liberal Party states that they open the major projects office in part to build clean energy infrastructure quickly, and of the 11 nation building projects that they've announced so far, they are categorizing eight of those 11 as clean economy projects. On top of these, Mark Kearney reiterated his commitment to building an East West electricity grid, which would link those our provinces together and help, like I said earlier, help that flow of electricity east to west, you know, between provinces improve, rather than, you know, right now, we have a lot of great north south connections between us and the United States. So the intent is that these projects will really position Canada as a leader in clean energy, help us achieve our own carbon reduction and net zero goals and ensure that we can manage growing demand for electricity. So we're in very early days of those projects yet, and what I'm highlighting here is that we expect to see a lot more information about those projects, about how they're going to proceed, timelines, etc, during the course of this year, and likely even see some new ones get added to that to that current list. So speaking of major projects, our next item that we're keeping an eye on is the Alberta to BC pipeline. This definitely has been a big new

    Holiday Rewind Part 2: electrifying conversations that lit up 2025

    In Part 2 of the Holiday Rewind, Trevor revisits five standout episodes from thinkenergy in 2025. The conversations focus on renewable energy, from Distributed Energy Resources (DERs) and building decarbonization to energy storage, district energy, and the policy forces shaping it all. This episode reflects on how renewables are becoming personal, scalable, and central to Canada's smart energy future. Listen in for a thoughtful look at the momentum we've built and the progress we made.   Related links   Episode 163 (How Distributed Energy Resources (DERs) are reshaping the grid): https://thinkenergypodcast.com/episodes/thinkenergy-shorts-how-distributed-energy-resources-ders-are-reshaping-the-grid/  Episode 150 (Decarbonizing Canada's buildings with the Building Decarbonization Alliance): https://thinkenergypodcast.com/episodes/decarbonizing-canadas-buildings-with-the-building-decarbonization-alliance/  Episode 152 (Capturing lightning in a bottle with Energy Storage Canada): https://thinkenergypodcast.com/episodes/capturing-lightning-in-a-bottle-with-energy-storage-canada/  Episode 154 (Reimagining heating and cooling with district energy systems): https://thinkenergypodcast.com/episodes/reimagining-heating-and-cooling-with-district-energy-systems/  Episode 149 (Looking ahead at 2025 clean energy trends): https://thinkenergypodcast.com/episodes/looking-ahead-at-2025-clean-energy-trends/ Trevor Freeman on LinkedIn: https://www.linkedin.com/in/trevor-freeman-p-eng-cem-leed-ap-8b612114/ Hydro Ottawa: https://hydroottawa.com/en     To subscribe using Apple Podcasts:  https://podcasts.apple.com/us/podcast/thinkenergy/id1465129405   To subscribe using Spotify: https://open.spotify.com/show/7wFz7rdR8Gq3f2WOafjxpl   To subscribe on Libsyn: http://thinkenergy.libsyn.com/ --- Subscribe so you don't miss a video: https://www.youtube.com/user/hydroottawalimited   Follow along on Instagram: https://www.instagram.com/hydroottawa   Stay in the know on Facebook: https://www.facebook.com/HydroOttawa   Keep up with the posts on X: https://twitter.com/thinkenergypod --- Transcript: Trevor Freeman  00:00 Welcome to thinkenergy, a podcast that dives into the fast, changing world of energy through conversations with industry leaders, innovators and people on the front lines of the energy transition. Join me, Trevor Freeman, as I explore the traditional, unconventional and up and coming facets of the energy industry. If you have any thoughts, feedback or ideas for topics we should cover, please reach out to us at think energy at hydro ottawa.com, hi everyone and welcome back. Welcome to the second of our special year end holiday rewind episodes that we do here on the think energy podcast, I'm your host, Trevor Freeman, in our last episode, we looked at five conversations or snippets of conversations that we thought, you know, helped shape the way we think about the grid, everything from politics to grid modernization to large scale investments, what Hydro Ottawa in particular is proposing to invest in our grid, but Today is all about the fuel that powers our clean energy future. And I don't mean all the candy and gingerbread and all the sugar that we're going to eat over the next little while, although those help too. I'm talking about renewable energy, solar, District Energy Systems, how we're using distributed technologies to really transform the way we generate and manage and use power here in Canada. Think of this episode as a bit of a, you know, warm fireside reflection on the progress that we've made, the momentum we're carrying into the year ahead. But also keep in mind how far we have to go. We've got more work to do, and 2026 needs to be another year of focusing on that. But today we're going to revisit portions of, you know, five conversations from 2025 that really show how renewable energy isn't just a trend, it's an accelerating shift that's reshaping our homes and our businesses, our communities and even the grid itself. So let's jump right in with our first clip. So today we're going to start with a clip that's close to my heart, because I talk about distributed energy resources all the time, and you guys hear me talk about that all the time with guests and in some of the solo episodes that I do, it's one of the clearest signs that renewable energy is moving from kind of the fringes of the grid, the very large centralized systems to really write on our own rooftops and backyards and on our businesses, DERs represent really that bottom up renewable revolution. So rooftop solar, home batteries, smart EV chargers and more, these are becoming technologies that our friends and neighbors and us, even the listeners of this podcast, have and are using to add real clean energy to the grid and using it in smarter ways. So here's a moment from my distributed energy resources episode that looks at how DERs are becoming those practical tools for resilience, for decarbonization and just for everyday energy use. So let's dive into what some of the reasons are why someone would want a der there's a couple of different reasons. The first is for backup during an outage. So using solar panels, especially if paired with a battery, can give you some backup if there's an outage from the grid, whether that's a storm or an accident or something like that, that backup power can be focused on your key devices or systems or appliances, or if your storage is big enough, or your system is big enough, it may be used to power your whole home for a period of time. Of course, if you're using one of those non renewable sources that I mentioned, like a fossil fuel power generator, for example, then your backup supply can last longer, really, as long as you've got fuel. But it's not clean, so you will be producing carbon emissions. One emerging technology that we'll likely see more of in the future is using an electric vehicle for this purpose. So while there's only a few different models that allow this right now, the Ford F150 is one of them, and there are some safety and regulatory considerations before you go ahead and do this, we can expect to see more of this in the future as the technology advances and it becomes a bit more widespread. Another reason for DERs is financial. Installing a der can actually help you save money every month, whether that's just by reducing what you consume from the grid, or by pushing back unused generation to the grid for credits, and I'll touch on this a little bit more shortly. Finally, if we're talking about those renewable DERs, they produce clean energy. So that's carbon free emissions, free energy. And if you are concerned about your carbon footprint, you're trying to decarbonize and reduce the amount of emissions that you cause. Renewable DERs are a great way to do that. You can lower your carbon footprint by reducing how much you draw from the electricity grid and any carbon emissions that are associated with that. You know what I love about this is just how simple. Empowering. It truly is. Renewable energy isn't industrial scale anymore. You know, everybody can at least envision themselves playing a part in the renewable transition. There's incentives out there to support putting renewables in the business case. Is starting to make sense for homes, for businesses, it's becoming local. And as these DERs grow, they don't just decarbonize homes, they also strengthen resiliency, and, you know, support the other drivers that people have for their energy, having more control over it, having resiliency and backup during outages, etc. And this theme of people having more agency and control over their energy really ties into the next clip that we're going to show as well. We're revisiting again we played this on the last holiday rewind, but we're revisiting our conversation with the Building Decarb Alliance about buildings. Buildings are one of Canada's largest sources of emissions. They're also one of the biggest opportunities for renewable driven change. So in this conversation with Brian Flanagan, we talk about how renewable energy and electrification, so from heat pumps to solar grid integrated building systems, how these things are reshaping the way we heat and cool and power the places that we live and work. And in this clip, I really think it captures the scale of the challenge and the optimism of the transition. You really can't overstate the importance of buildings in our lives. We eat, sleep, work, learn and socialize in buildings, among many, many other things, a huge percentage of our lives takes place inside buildings. In fact, most of us probably have to make a conscious effort to actually spend time outside of buildings. I know that I try to make a point of spending time outside every day, and I have to be conscious about it, because it might not otherwise happen. And as a result of that, centrality in our lives, buildings are major users of energy. Some estimates say that around 30 to 40% of energy use in Canada is associated with buildings, and they're also a major source of greenhouse gas emissions. So around maybe 18% or so in Canada. That means that the buildings themselves and the way we build them, the way we heat them, the way we use them, are an important part of our efforts to decarbonize and to further the ongoing energy transition.   Bryan Flannigan  07:24 We tend to focus on kind of four main areas, making sure that there's policy support at various levels of government, and understanding which policies might be effective and which ones might be less so, and trying to advance the ones that are high leverage, looking at the grid impacts of electrifying buildings. Because it's undeniable that if you switch from fossil combustion of fossil fuels to electricity, you require a clean electricity system that has to have the capacity and be robust enough to support that. So we want to be clear about that. We want to

    Holiday Rewind Part 1: electrifying conversations that lit up 2025

    Canada's energy transition isn't coming. It's already here. As 2025 winds down, Trevor shares a holiday rewind featuring five of the most electrifying conversations from the thinkenergy podcast this year. From clean energy trends and Hydro Ottawa's investment plan to grid modernization, the rise of DERs, and decarbonizing buildings. Sit down with something warm and revisit the insights, challenges, and big ideas that defined our fast-moving energy landscape in 2025.   Related links   Episode 149 (Looking ahead at 2025 clean energy trends): https://thinkenergypodcast.com/episodes/looking-ahead-at-2025-clean-energy-trends/ Episode 160 (Digging into Hydro Ottawa's historically large investment plan): https://thinkenergypodcast.com/episodes/summer-rewind-digging-into-hydro-ottawas-historically-large-investment-plan/  Episode 162 (Consumer impact: revisiting grid modernization with Capgemini Canada): https://thinkenergypodcast.com/episodes/consumer-impact-revisiting-grid-modernization-with-capgemini-canada/  Episode 163 (How Distributed Energy Resources (DERs) are reshaping the grid): https://thinkenergypodcast.com/episodes/thinkenergy-shorts-how-distributed-energy-resources-ders-are-reshaping-the-grid/  Episode 150 (Decarbonizing Canada's buildings with the Building Decarbonization Alliance): https://thinkenergypodcast.com/episodes/decarbonizing-canadas-buildings-with-the-building-decarbonization-alliance/  Trevor Freeman on LinkedIn: https://www.linkedin.com/in/trevor-freeman-p-eng-cem-leed-ap-8b612114/ Hydro Ottawa: https://hydroottawa.com/en     To subscribe using Apple Podcasts:  https://podcasts.apple.com/us/podcast/thinkenergy/id1465129405   To subscribe using Spotify: https://open.spotify.com/show/7wFz7rdR8Gq3f2WOafjxpl   To subscribe on Libsyn: http://thinkenergy.libsyn.com/ --- Subscribe so you don't miss a video: https://www.youtube.com/user/hydroottawalimited   Follow along on Instagram: https://www.instagram.com/hydroottawa   Stay in the know on Facebook: https://www.facebook.com/HydroOttawa   Keep up with the posts on X: https://twitter.com/thinkenergypod -------- Transcript: Trevor Freeman  00:00 Welcome to thinkenergy, a podcast that dives into the fast, changing world of energy through conversations with industry leaders, innovators and people on the front lines of the energy transition. Join me, Trevor Freeman, as I explore the traditional, unconventional and up and coming facets of the energy industry. If you have any thoughts, feedback or ideas for topics we should cover, please reach out to us at think energy at hydro ottawa.com, hi everyone, and welcome back. This is our special holiday rewind edition of the thinkenergy podcast, which has become a bit of a tradition around here. I'm your host, Trevor Freeman, and as we settle into the final days of the year, it feels like the perfect time to slow down and take a look back at some of the conversations that we feel really shaped 2025 at least, for the podcast and in our own minds. This year, we explored everything from grid modernization to decarbonizing buildings distributed energy resources (DERs) and some of the technologies that are really defining how Canadians live, work and stay connected. Today's episode is the first of a two-part holiday rewind series, each part highlighting five standout episodes that we feel really sparked ideas curiosity and great discussions throughout the year. So pull up a comfortable seat, pour yourself something seasonal and festive, and join me as we revisit some of the insights and innovations that we feel lit up 2025 to start with, we kicked off 2025 with a forward looking conversation on some of the trends that we thought might shape the year, and to be honest that many of them unfolded even more quickly than we expected. In our first episode of 2025 we looked at clean energy trends. We talked through how electrification and AI driven grid intelligence and new customer expectations were really going to change the landscape in real time for us, here's a moment that we captured just how quickly the industry is accelerating and why adaptability is so important to us. At the same time, utilities across the country will continue to invest in grid modernization. So as well as infrastructure expansion, not just modernization, we're also building and growing our grids to keep up with the pace of change, but we need to also be able to leverage more DERs on the grid, so more distributed energy resources, small scale solar generation, things like that. So we will continue to see utilities make steps in that direction. They will look to levels of government to support those initiatives, through programs and funding and regulatory change. So we will continue to see that change in grid modernization, but I know it's definitely a big topic for us here at hydro Ottawa. And finally, in this section, energy efficiency. Energy efficiency is not new. It's been around for quite a while. In fact, it was the primary focus, kind of before we shifted a little bit more towards thinking about carbon. But we cannot fully decarbonize, we cannot fully electrify without significant energy efficiency. We just won't be able to affordably build the infrastructure we need if we're not using energy in an efficient way. So that will continue to be a focus. And in fact, I mentioned the new incentive programs from the province of Ontario that is very much designed to support ongoing energy efficiency measures. So we will continue to see that as a focus in 2025 and our final area, area number five, is technology. So there is no year anymore. In fact, maybe there never was where technology doesn't continue to grow and expand and evolve in ways that we couldn't even imagine, and it does seem like the pace of change is picking up, but I think that's kind of normal. So we will see technology that supports or augments the energy transition continue to evolve in 2025 and the ways that technology influenced that really, you know, we have an idea on some of them, and it'll be interesting to look back in 12 months at what we know in December, 2025 that we didn't even know here today in January. So there you have it. That's going back 12 months. And my expectation of what 2025 might have in store in the new year, I'll be doing a similar deep dive on some of the trends that we've been seeing over the course of this year and what we might expect to continue into 2026 but that idea that the pace of change is accelerating certainly became one of the defining themes of the year, and I think is something that we can expect to stick with us for the foreseeable future. And I think you'll hear echoes of that in all the different episodes that we revisit today. Next up, a modern, reliable grid doesn't just happen. It's built through long term planning, thoughtful investments and a deep understanding of how our communities are growing and how their energy needs are changing. In an episode that we. Least back in June, we unpacked hydro Ottawa's 2026 to 2030 investment plan, and what that means for reliability and customer experience and preparing the system for tomorrow. In this next clip, I chat with Hydro Ottawa's Guillaume Paradis to really get into why it's so critical that we get our investment in the next five years, right for our grid, so that that's a nice segue into his next question, which is, of course, there's a cost for this, and this is why it is an investment plan we're out there outlining. These are our targets. This is what we want to do, but there's a cost to that, and so if we don't do this, if we said, look, we just can't put that extra investment into these areas, what are the implications on the grid, on our service? And let's look at kind of like, quality of service, reliability, safety, etc, if we don't make these investments that we are identifying right now.   Guillaume Paradis  06:03 Yeah, so it's pretty direct, right? What we've done for the in preparation for our rate application, in preparation for to develop our plans for 26 to 2030 is we've considered all the needs. We've looked at how old the assets are, how quickly they're deteriorating, how many might require replacement over the next five years, what would be an appropriate rate of replacement to ensure that we don't let risk build up in our system, we don't cause reliability issues. We've looked at how we make sure that we can provide service to our customers, that we can connect them in a timely manner, that we can do all those things in a fashion that is safe and ensures the safety of the public, our customers. And so a lot of thought goes into what is required over the next five years. And then on top of those factors and considerations, we also look at what impact will this have financially on our customers, because we're mindful that our service does affect, you know, our customers live, yes, in a positive manner when our service is reliable and power is available, but also financially. From a cost standpoint, we add to other pressures that everyone experiences in their lives, and so we want to be very judicious in setting the size of our programs the level of investments in managing those various factors, right? So we have a multifaceted responsibility, and we weigh all those factors in in our setting the plans for the future. So doing so looking five years out, as you can probably imagine, you know, if we didn't constrain the plans, if we just did everything our planning engineers would like to do, we would have spent probably another 50% more than what is in the current plan. So looking at old assets, looking at the service levels we want to deliver, we could have spent a significantly larger amount of money if it was purely based on we'll call them planning, you know, drivers. But as I said, we are mindful that we're responsible for the quality of our service on behalf of all our customers.

    Blue energy: powering the future with Marine Renewables Canada

    Waves, river currents, and tidal turbines could help power Canada's clean energy future. Trevor speaks with Elisa Obermann, Executive Director at Marine Renewables Canada, about the promise of marine energy and how countries like Canada are pursuing its potential. They explore how emerging 'blue energy' technologies complement solar and wind, support coastal and Indigenous communities, and move us toward a more sustainable, diverse net-zero grid.   Related links    Marine Renewables Canada: https://marinerenewables.ca/ Fundy Ocean Research Center for Energy (FORCE): https://fundyforce.ca/ canmetENERGY: https://natural-resources.canada.ca/science-data/science-research/research-centres/canmetenergy Yuquot Wave Energy Project: https://barkley.ca/project/yuquot-wave-energy-project/ Blind Channel Tidal Energy Demonstration Centre: https://onlineacademiccommunity.uvic.ca/primed/blind-channel/ European Marine Energy Center (EMEC): https://www.emec.org.uk/ Canadian Hydrokinetic Turbine Test Centre: (CHTTC): http://www.chttc.ca/ Elisa Obermann on LinkedIn:https://www.linkedin.com/in/elisa-obermann-07469245/    Trevor Freeman on LinkedIn: https://www.linkedin.com/in/trevor-freeman-p-eng-8b612114    Hydro Ottawa: https://hydroottawa.com/en      To subscribe using Apple Podcasts:  https://podcasts.apple.com/us/podcast/thinkenergy/id1465129405   To subscribe using Spotify: https://open.spotify.com/show/7wFz7rdR8Gq3f2WOafjxpl   To subscribe on Libsyn: http://thinkenergy.libsyn.com/ --- Subscribe so you don't miss a video: https://www.youtube.com/user/hydroottawalimited   Follow along on Instagram: https://www.instagram.com/hydroottawa   Stay in the know on Facebook: https://www.facebook.com/HydroOttawa   Keep up with the posts on X: https://twitter.com/thinkenergypod --- Transcript: Trevor Freeman  00:00 Welcome to thinkenergy, a podcast that dives into the fast, changing world of energy through conversations with industry leaders, innovators and people on the front lines of the energy transition. Join me, Trevor Freeman, as I explore the traditional, unconventional and up and coming facets of the energy industry. If you have any thoughts, feedback or ideas for topics we should cover, please reach out to us at think energy at hydro ottawa.com, hi everyone, and welcome back. I have a really great conversation for you today, but before I get to that, I think it's worth a minute or two of time to revisit some first principles people approach the energy conversation from all different backgrounds and angles, and I think it's good to make sure that we're all on the same page when it comes to some foundational knowledge before we dive into our topic today, the thing that I want to quickly review is electricity generation. Now don't worry, we're not going to get into an advanced physics level of knowledge on this, but I just want to quickly refresh everyone on the basics. And by the same token, to all of you advanced physics folks out there that are listening, please forgive me if I'm slightly off on a detail or two, as long as I don't mess up the core foundational information. So for the most part, the electricity that we use is primarily generated by spinning a coil of wire around a magnet, or inversely, spinning a magnet inside a coil of wire that causes electrons to move, and that flow of electrons is electricity. For the most part, that combination of coiled wire and magnets and a spinning motion is what makes most of our electricity. There is one major exception to this, which is solar power that doesn't involve spinning anything. But other than that, our major electricity sources utilize that spinning motion, and I'm not including hydrogen fuel cells here as a major source of electricity. So let's keep going with this spinning idea. Then the next question is, how do we make things spin? One very common method is heat. Let's say you burn something, coal or natural gas, for example, which creates heat. You then use that heat to boil water, which makes steam, which you can push at high pressure against turbine blades to make them spin. It's as simple as that. The problem is, burning things creates harmful emissions, which are causing climate change. You can also generate heat with non emitting sources, and a major one, especially here in Ontario, is nuclear power, splitting atoms in a controlled environment, a nuclear reaction generates heat and then the process is the same as previously described. So as complex as a nuclear reactor is its main purpose when it comes to electricity generation, is simply making heat so we can boil water and create steam, et cetera, other than heat. The other way to make things spin is to utilize naturally occurring kinetic energy. So that means something that's already happening out there that carries a lot of force that can push a turbine blade. This would include wind energy, so using the force of the wind to turn large wind turbines and hydro electricity, which uses water being pulled downhill by gravity, so a flowing river or a large dam to turn that turbine the same end results that spinning motion, but no need to create heat to get there. We're almost done with the science lesson, so just bear with me for another few seconds as we think about reducing our carbon emissions, finding ways to generate electricity that don't require burning fossil fuels is really important. Solar definitely has a role to play, but we also need more emissions free ways to spin things. I mentioned some of the more traditional ones, like solar and wind energy, but today's conversation is about some lesser known, emerging methods, which are covered by the term marine renewable energy generation. Phew, it was a long walk to get there, but we finally got here. All of that is to tee up my conversation today with Elisa Obermann, the Executive Director of Marine Renewables Canada. Marine Renewables Canada is the National Association for tidal wave and river current energy in addition to offshore wind. But it's those first three generation strategies that I am particularly interested in as non mainstream ways to spin things. These technologies are known as blue energy, but are often overshadowed by the more common renewable energies that we talked about, solar and wind generation. So I'm really excited to chat with Elisa to shed some light on them. Today. Elisa has served as the executive director of marine renewables Canada since 2015 she's a founding member of both the Electricity Alliance Canada and the Canadian Council on Renewable Electricity. She has also worked for several other organizations that focus on clean technology, tidal energy and the broader renewable energy sector, including Sustainable Development Technology Canada, the Fundy Ocean Research Center for Energy. Which you'll hear us talk about today as force and Nova scotia's Department of Energy. Elisa Obermann, welcome to the show.   Elisa Obermann  05:07 Hi. Thank you very much for having me.   Trevor Freeman  05:09 So, let's start off kind of with the basics. Elisa, why don't you tell us a little bit about your background and how you got into this pretty unique space in the energy sector that we're going to dive into a little bit more.   Elisa Obermann  05:22 Sure. So I decided after doing my undergrad, so I'm going kind of way back here, all the way back. Yeah, exactly. I did a degree, a bachelor's degree in English, but I really wanted to get involved in something that would help me do more for the environment, play a role in the future. So I decided to go back to school to do a public policy degree. And the first internship I had was with Nova Scotia Department of Energy, and it was actually on the oil and gas side of things, but my thinking was, well, this will get me eventually to where I want to go and working more in renewables. And that's essentially exactly what happened. And so I started working more and more there on renewable energy. Then started working on the province's marine renewable energy strategy. So it really kind of got me into this kind of path of, you know, working on climate change and renewable energy. And the other thing I will also say is that I grew up in Maine and really close to the ocean, and so after university, I moved to Toronto for a while, and I thought to myself, like, I really just want to do something that takes me back to the ocean. So this really combines both kind of goals I had for myself, in terms of working to protect and help the environment, and then also staying close to the ocean.   Trevor Freeman  06:35 Yeah. I mean, that makes a ton of sense. It's interesting. I talked to a lot of people, obviously, and often the question of career path comes up, and it's funny to see the things that we're passionate about in those early days, no one could guess how that comes to fruition later on in our careers. And you know, I've got some similar stories of wanting to save the world when I was in university and having no idea how the different paths that that would take me on. So great to hear your story. Thanks for sharing that. Tell us now a little bit about your organization, marine renewable Canada, and you know, kind of its vision for how marine renewables will fit into the energy sector.   Elisa Obermann  07:10 Yeah. So marine renewables Canada is a National Association. We're headquartered in Halifax, but we do work across the country, and actually, our beginnings were in British Columbia, really starting around like wave energy, small scale projects. One of our founding members at the time was BC Hydro. We now have over 200 members, and that's really grown just in the past couple years, because our focus is on wave, tidal, river current energy, but also offshore wind. And so there's been a lot of excitement, especially on the East Coast, around offshore wi

    thinkenergy shorts: hydropowering Ontario's north with renewable energy

    Hydropower is one of the oldest sources of renewable energy, powering Canada's first electric lights in 1881 and providing clean energy to six out of ten homes and businesses today. Ontario's north leads its next chapter. Trevor sums up how new hydro projects with First Nations transform remote communities, reduce diesel reliance, and support reconciliation. With billions invested in refurbishing plants and expanding the grid, it's a story of clean energy, collaboration, and Canada's sustainable future.   Related links   ●       Electrifying Canada's remote communities with QUEST Canada (thinkenergy episode 143): https://thinkenergypodcast.com/episodes/electrifying-canadas-remote-communities-with-quest-canada/ ●       Watay Power Project: https://www.wataypower.ca/   ●       Trevor Freeman on LinkedIn: https://www.linkedin.com/in/trevor-freeman-p-eng-8b612114   ●       Hydro Ottawa: https://hydroottawa.com/en     To subscribe using Apple Podcasts: https://podcasts.apple.com/us/podcast/thinkenergy/id1465129405   To subscribe using Spotify: https://open.spotify.com/show/7wFz7rdR8Gq3f2WOafjxpl   To subscribe on Libsyn: http://thinkenergy.libsyn.com/ --- Subscribe so you don't miss a video: https://www.youtube.com/user/hydroottawalimited Follow along on Instagram: https://www.instagram.com/hydroottawa   Stay in the know on Facebook: https://www.facebook.com/HydroOttawa Keep up with the posts on X: https://twitter.com/thinkenergypod - Transcript: Trevor Freeman  00:07 Welcome to a think energy short hosted by me, Trevor Freeman. This is a bite sized episode designed to be a quick summary of a specific topic or idea related to the world of energy. This is meant to round out our collective understanding of the energy sector, and will complement our normal guest interview episodes. Thanks for joining and happy listening. Hi everyone, and welcome back to think energy. I'm your host, Trevor Freeman, and today we're shifting our lens to the north. Across North America, we are seeing a resurgence of hydro power, and that includes here in Ontario, where I'm located, this province is looking to this long standing generation method to power Canada's growing and energy starved northern communities first. Let's take a quick look back at history. Canada's first electric lights were actually powered by hydro power. Back in 1881 a small hydro electricity plant in Sherbrooke, Quebec lit up the night and sparked a clean energy story that's still unfolding today, from those earliest River power lights to today, where we see more than 200 hydro stations generating over 60% of Canada's electricity and about 90% of our renewable power. Hydro power remains backbone of our clean energy system and powers six out of 10 homes and businesses. It's reliable, it's cost effective, and unlike solar wind, which can be intermittent, water, provides a steady stream of power pretty much 24/7 some plants have even been operating for more than a century. But according to water power Canada, because we've been relying on this source for so long, there is actually a lot of untapped potential that can be realized by refurbishing and modernizing our older facilities, not to mention developing new ones. We could significantly expand clean capacity, which would help us move closer to our net zero goals. As I've said before on the show, we need every tool in the toolbox, and expanding hydro power is one of those tools. So let's have a look at the North American resurgence of hydropower across the continent, there is a renewed focus on this source as a stable, long term solution to rising energy demand. Even the tech sector is taking notice. In July 2025 Google announced a $3 billion deal to secure hydro power from two US facilities in Pennsylvania through Brookfield asset management. It is the largest corporate clean energy agreement of its kind, which is a signal of how essential reliable renewable power has become. In this digital age, we need something to power these giant AI data centers, and these corporations are looking for something that's reliable and clean. The hydropower sites will be upgraded and relicensed under the agreement, and Google also intends to expand the deal into other regions of the US, Midwest and mid Atlantic, where it's investing $25 billion in new data centers. This deal signals a shift in corporate energy procurement, from simply buying renewable energy credits to offset their emissions to directly investing in specific, large scale, long duration infrastructure deals to power businesses. Of course, this definitely raises questions about the implications for how the grid and energy markets may evolve as demand in the tech and business sector continues to change and grow. That's something we'll explore at a different time. While Google's deal is driven by data and growth. Ontario's story is being shaped by geography, reconciliation and regional development. So let's have a look to the north. Like we said we would when electricity grids were first built, many northern and remote communities were left out because connecting them wasn't seen as practical or affordable. I talked about this with Gemma Pinchon from Quest Canada about a year ago on this show. Have a listen if you haven't already. With small populations spread across vast distances, it was considered too costly to run transmission lines that far north. So while the rest of the country was plugged into their provincial grids, many of these communities were left to rely on local diesel generation, a decision that might have made economic sense at the time, but definitely isn't equitable and not great for the environment. Thankfully, we're seeing some movement in this area. New investments and partnerships are changing how energy is produced and shared, and Ontario is turning once again, to our water power routes, but this time, it's doing it differently. This year, the Ontario government announced several new partnerships with First Nations that are changing the way clean energy projects take shape, emphasizing shared ownership, community leadership and lasting local benefits. New hydro developments in the north are being co created with First Nations who've lived alongside these rivers for generations. So let's have a look at some specifics. In July, the province announced plans for two new large scale hydro electric stations in northern Ontario, the Nine Mile rapids project on the Abitibi River and the Grand Rapids project on the Mattagami. Together, these could generate up to 430 megawatts of clean electricity that's enough to power. Nearly half a million homes. This is the province first large scale expansion of hydro electricity facilities in decades. What makes these projects truly historic is who's at the table. The stations will be co developed with the Taykwa Tagamu Nation and the Moose Cree First Nation, marking a shift towards shared ownership and long term community benefit. It's a model of collaboration that intertwines energy expansion with economic reconciliation, and this is just part of a larger effort. Ontario has also committed $4.7 billion to refurbish and expand existing hydro electric facilities across the province, from Northern Ontario to Niagara Cornwall and all the way out east. Together, these upgrades could add another 5000 megawatts of reliable clean power. It's a move that fits squarely within Ontario's long term plan to meet rising demand in the north with reliable low carbon power. The IESO, our system operator, predicts northern Ontario's demand for electricity will increase by 81% by 2050, higher than the provincial average. Of course, generating electricity is only half the story, as we've talked about before. It needs to reach the people in the industries that need it to make that happen, Ontario is working with transmission partners to build 1000s of kilometers of new power lines across the north. A prime example is Watay Power, the largest indigenous led grid connection project in Ontario's history. It's 1800 kilometers of transmission lines will connect more than 18,000 people across 16 remote First Nation communities to the provincial grid for the first time, ending decades of dependence on diesel. These grid expansions are also laying the groundwork for future economic development, especially in the mineral rich Ring of Fire region. The province recently signed a 39 and a half million dollar community partnership agreement with the Wabequie First Nation to support infrastructure early works and an all season road that will unlock access to critical minerals essential for EV batteries and clean technologies. Hopefully, this is a sign that we're seeing a real shift in how Canada views its north, not just as a remote region, but as a cornerstone of the country's future. The federal government is linking energy development, mining and national security in a way that we haven't seen in decades. There's renewed investment in hydro and transmission projects, plans to tap into critical minerals for the clean economy and a growing military infrastructure to reinforce sovereignty in the Arctic. It's all part of a bigger effort to power the north, protect it and ensure the communities who live there share the benefits of its growth. So what does all this mean? Ontario's investments aren't just about electricity. They're about sovereignty, sustainability and self determination. They represent a vision for Canada's north, where the local power generation, indigenous leadership and economic opportunity grow together. Still, there are important questions ahead that we'll all be watching. How will the province balance clean growth with ecological protection? How can partnerships ensure that the benefits of these projects are lasting and equitable for both the province and First Nations leading this work on their own traditional lands? In the end, the real ene
