    Re-release: Building the plane while it’s flying: data centers, utilities, and the new rules of power

    After more than a decade of flat demand, the US power sector is now facing explosive growth, arriving faster than grids, generation, and transmission can be built. In this episode, Interim host of Interchange Recharged Bridget van Dorsten is joined by Chris Seiple, Vice Chairman of Power & Renewables at Wood Mackenzie, to unpack one of the defining challenges facing the modern energy system: how utilities, developers, and policymakers are responding to an unprecedented surge in electricity demand driven by data centres, AI, and reshoring manufacturing.  Bridget and Chris explore what makes this moment different, why planning cycles are colliding with short technology investment horizons, and how this mismatch is forcing a fundamental rethink of how the power business works, from energy policy to energy finance. The main point is that the difference between regulated and deregulated markets is widening, as vertically integrated utilities strengthen their advantage in managing large loads. New mechanisms like large-load tariffs are reshaping rate design, investment risk, and affordability - Chris explains how. Plus, deregulated markets may be approaching a tipping point, as traditional price signals struggle to accommodate demand arriving at this scale and speed. What does it all mean for energy? Crucially, the episode looks beyond the immediate crunch to the longer-term implications for the energy transition. From renewable energy and solar energy pipelines to grid resilience, transmission innovation, and behind-the-meter solutions, this demand boom could become a powerful catalyst for clean tech, clean technology, and energy innovation, even as subsidy regimes change and capital costs rise. The discussion also touches on the role of hydrogen, nuclear, and emerging grid technologies in supporting future energy projects, and why this period of rapid load growth may ultimately accelerate decarbonisation rather than slow it. If you’re tracking climate policy, climate change, green finance, and long-term energy predictions, this episode is for you; hear why today’s data centre boom could shape the next several decades of the power system.

    When hydro is no longer enough: Colombia’s race to diversify before the next El Niño

    Colombia’s power system was built around a powerful advantage: abundant hydropower backed by domestic gas, delivering electricity that was relatively cheap, relatively clean, and largely local. But that model is coming under pressure from two directions at once. Climate volatility is making dry years more dangerous, and gas is no longer the easy fallback it once was. As a potentially severe El Niño approaches, the central question is no longer just how much installed capacity the country has on paper. It is whether the system has enough firm, flexible energy to meet rising demand without driving up prices or risking shortages. Host Sylvia Leyva Martinez is joined by Álvaro Villasante, Vice President of Business Management and Innovation at Grupo Energía Bogotá, to examine how that shift is changing the energy debate in Colombia. Their core argument is that hydropower remains a strategic strength, but it can no longer be treated as a sufficient foundation on its own. As gas production declines and imports become more important, the backup system is getting more expensive and more exposed, turning what used to be a relatively stable balance between hydro and thermal generation into a more fragile equation shaped by infrastructure, timing, and security of supply. A large part of the discussion focuses on what can realistically be done before the next stress event arrives. Álvaro argues that long-term renewables auctions are directionally right, but they do little to solve an immediate risk window running through 2026 and 2027. In the near term, the priorities are more practical: manage reservoirs carefully, accelerate gas-import infrastructure, and treat demand response and energy efficiency as system tools rather than side issues. The broader lesson comes from Brazil, where a more diversified generation mix and stronger transmission buildout have made it easier to move power across regions and absorb volatility, offering a useful contrast for a Colombian system still trying to catch up on grid investment. The episode also broadens the conversation beyond market design and megawatts. Álvaro makes the case that energy security is ultimately about people: whether infrastructure reaches communities, whether electricity remains affordable, and whether reliable access is treated as a development priority rather than an abstract policy goal. The takeaway is that Colombia’s next energy challenge will not be solved by one technology alone. It will be decided by how quickly the country can move from discussion to execution on gas, transmission, renewables, storage, and demand-side measures before climate pressure exposes the full cost of delay.

    The fastest path to more power: How advanced conductors could unlock grid capacity without new transmission

    The pressure on the power system is no longer theoretical. AI, data centers, electrification, and new industrial load are arriving faster than utilities can build generation and transmission through conventional timelines. One of the least glamorous but potentially most consequential answers to that problem is how to get more capacity out of the wires already in the ground and hanging overhead.  Host Sylvia Leyva Martinez is joined by JD Sitton and Theodore Paradise of CTC Global to examine why advanced conductors are moving from a niche grid technology to a mainstream tool for utilities under pressure to deliver speed, affordability, and reliability at the same time. They explain how replacing traditional steel-core conductors with carbon-core alternatives can sharply reduce sag, increase thermal performance, and in many cases double capacity on existing rights-of-way without rebuilding towers or waiting a decade for a new line. The conversation explores why that matters now. As Theodore argues, the grid was already under strain before AI accelerated the problem, with aging generation, load growth from electrification, and mounting congestion already testing the system. What changes in this moment is the pace. A reconductoring project can be completed in roughly 18 months, compared with five to seven years for a rebuild and 10 to 15 years for a new parallel line. JD and Theodore make the case that this speed advantage is not just about meeting data-center demand. It is also about cutting costs, easing permitting friction, reducing community opposition to new infrastructure, and improving safety by lowering the risk of heat-driven sag and vegetation contact.  Crucially, the episode asks what reliability should mean in a grid era defined by bigger load swings, tighter operating margins, and rising public scrutiny over cost. From wildfire resilience to real-time line monitoring and the ability to operate with greater confidence under stressed conditions, advanced conductors are presented not as a silver bullet, but as a proven, underused tool that could help utilities move faster and make better use of capital already committed to the system. The larger question running through the episode is whether the industry will look back on this moment and conclude that one of the simplest grid-capacity solutions was available all along.

    Speed to power: Why data-center load growth is creating a new opening for C&I solar, storage, and microgrids

    After a decade of flat demand, power markets are being forced to absorb a very different problem: rapid load growth arriving faster than transmission, large-scale generation, and utility interconnection processes can respond. The focus shifts from utility-scale procurement to the distributed edge of the system, where commercial and industrial solar, community solar, batteries, and microgrids may prove to be some of the fastest tools available for adding capacity, managing costs, and improving resilience. Host Sylvia Leyva Martinez is joined by Tim Montague, host of Clean Power Hour and a longtime C&I solar operator and advisor, to unpack what distinguishes distributed generation from utility-scale solar in practice. Tim explains why the differences are not just about megawatts, but about interconnection, contractor capability, state policy, and execution risk. He also lays out how the phase-down of the ITC and the July 4 Safe Harbor deadline sharpened those differences: sophisticated developers with capital and pipeline visibility bought themselves runway through 2029, while smaller players that missed the deadline now face a much tighter path to commercial operation. The conversation then turns to the economics and mechanics of the market. Tim argues that state-level frameworks remain decisive for C&I and community solar, pointing to states such as Illinois, New York, New Jersey, Massachusetts, Maryland, Minnesota, Colorado, and New Mexico as the sector’s core proving grounds. From workforce rules and training pipelines to tax-credit capture and commercial lending, he describes a market that is far more fragmented than utility-scale power, but also more flexible. Financing can range from a local business borrowing through its existing commercial bank to larger developers using institutional capital to safe-harbor equipment and scale portfolios, while PPAs remain available but often introduce longer, more complex contracting cycles. Crucially, the episode looks at why distributed energy is moving from a niche resilience play to a system-level answer for affordability and speed to power. Rising electricity prices, data-center demand, and long utility interconnection queues are improving the case for solar-plus-storage behind the meter and at community scale. Tim makes the case that batteries, community solar, distributed computing, and eventually community-scale microgrids can complement, not replace, utility-scale buildout by delivering capacity where it is needed faster and with more local value. The core question running through the episode is whether the next phase of the energy transition will be defined not only by bigger projects, but by a more distributed grid architecture built for flexibility, resilience, and cost control.

    Thorium’s nuclear pitch: Can molten salt reactors cut cost, use waste, and scale faster than conventional designs?

    Electricity demand is rising, capital is tightening, and nuclear is back in the conversation as utilities, governments, and large power users look for firm low-carbon supply. But the central question is not whether advanced nuclear can attract interest. It is whether any new design can get far enough ahead on cost, manufacturability, and fuel strategy to break from the economics that have constrained conventional nuclear for decades. Host Sylvia Leyva Martinez is joined by Thomas Jam Pedersen, co-founder and CEO of Copenhagen Atomics, to examine one of the more unconventional answers now being put forward: thorium molten salt reactors built around low-pressure operation, standardized manufacturing, and a fuel strategy that could use spent nuclear fuel alongside thorium. Their core argument is that most of the nuclear sector is still trying to improve on a legacy light-water model that may remain too expensive, too complex, and too slow to scale against the pace of future energy demand. A large part of the discussion focuses on what that alternative looks like in practice. Pedersen argues that operating at atmospheric pressure changes the cost and engineering profile of the reactor itself, making smaller units easier to manufacture and potentially easier to deploy repeatedly. He also lays out why Copenhagen Atomics sees spent fuel not only as a waste problem but as a potential input, provided it can be recycled economically and paired with thorium to achieve higher fuel efficiency. The commercial model follows the same logic: standardize the reactor unit, let customers source the rest of the plant locally, and avoid the bespoke, first-of-a-kind economics that have burdened much of the sector. The episode also looks ahead to the harder constraints that will determine whether that thesis holds. Licensing remains slow and expensive, investor appetite is still shaped by the long history of political and regulatory risk in nuclear, and even successful advanced designs are unlikely to make a meaningful dent in global electricity supply before 2035. The takeaway is that the real test for advanced nuclear is no longer just technical credibility. It is whether a new generation of reactor companies can prove they have found a model that lowers cost, reduces deployment risk, and makes nuclear scalable in a very different energy market.

    The inverter security turn: How Europe and the US are redrawing solar procurement around Chinese hardware

    Solar demand remains strong, storage is scaling fast, and inverter technology is becoming more central to how modern power systems actually function. But the conversation around inverters is no longer just about efficiency, bankability, or price. As these devices take on more intelligence — managing batteries, supporting grid stability, and communicating more directly with the wider system — they are also being treated as a new point of strategic vulnerability. In both Europe and the US, policymakers are starting to respond accordingly. Host Sylvia Leyva Martinez is joined by Joe Shangraw, research analyst at Wood Mackenzie covering solar inverter markets, to examine what that shift means in practice. Their core argument is that inverter policy is moving beyond trade protection and into a more complicated mix of cybersecurity, industrial strategy, and grid risk. They unpack why Europe’s March decision to block public EU funding for projects using Chinese-made inverters matters beyond its immediate scope, and why the region’s dependence on Chinese vendors — especially in utility-scale string inverters and integrated battery-plus-inverter systems — makes any attempt to diversify more complex than simply switching suppliers.  A large part of the discussion focuses on the FCC’s July decision to add foreign power inverters to its Covered List, where the real issue is not just whether the headlines overstated the impact, but how narrowly or broadly the rule will ultimately be applied. Shangraw explains that the current language appears closely tied to communications hardware, especially wireless-enabled devices, which creates a more nuanced picture than an outright market shutdown. That distinction matters because it affects not only which new products fall in scope, but how developers, manufacturers, and asset owners start thinking about software updates, grid-code compliance, and long-term procurement risk. The challenge is no longer just cost competitiveness. It is whether an inverter can remain usable, updateable, and policy-safe over the life of the asset. The episode also looks ahead to the next set of decisions facing the industry: whether Europe expands restrictions beyond publicly funded projects, how quickly US and allied manufacturers can localise enough of the supply chain to qualify under tougher domestic-content rules, and where practical bottlenecks are most likely to emerge. The takeaway is that inverter policy is becoming a test case for a much bigger energy-transition problem: how to reduce genuine security risks without creating new deployment constraints. For developers, manufacturers, and policymakers alike, the inverter market is no longer just a technology contest. It is becoming a test of how the energy transition handles security, industrial policy, and system reliability all at once.

    Why biomining might finally work: How Endolith is using microbes and data to unlock more copper from low-grade ore

    Copper is moving from background commodity to frontline constraint. Demand is rising fast, high-grade deposits are getting harder to find, and the lead times for bringing new supply online remain brutally long. That matters not just for renewables and electrification, but for the basic energy resilience of modern life: the wires that keep lights on, water running, refrigeration working, and data centres scaling all depend on a metal the industry already knows is becoming harder to source. Host Sylvia Leyva Martinez is joined by Liz Dennett, founder and CEO of Endolith, whose career spans Wood Mackenzie, AWS, and NASA-linked astrobiology research, to explore a biological approach to one of mining’s toughest problems. Endolith uses microbial communities, what Dennett calls “the world’s oldest miners," to help recover more copper from low-grade ore in existing heap leach operations. The company’s core thesis is that copper supply can be made more elastic not by rebuilding mine sites from scratch, but by layering biology, sensing, and robust data architecture into brownfield operations that are already running.  Liz explains how that works on site: low-grade ore is stacked into large heaps, irrigated with sulfuric acid, and treated with microbes that accelerate the chemical pathways needed to liberate more copper into solution. The appeal is not futuristic moonshot capex, but a modular, plug-and-play system designed to fit into existing mine infrastructure with minimal downtime. The discussion looks at why that matters economically. Endolith is targeting ore bodies and waste streams that are currently too messy, too low grade, or too contaminated to recover efficiently through conventional routes, including arsenic-rich material that can be especially problematic for smelting. In lab settings, the company has seen significantly higher recovery, and even modest incremental gains in the field could translate into a meaningful unlock when the underlying mine and processing system are already built. The conversation also asks why biomining may be having its moment now, after decades of false starts. Liz argues that the breakthrough is not microbes alone, but the combination of microbial science, cloud-scale data systems, and faster experimentation that lets teams build and iterate far more effectively than even a few years ago. From there, the conversation broadens into the strategic question underneath Endolith’s business: how to increase copper supply in a world where demand is being pushed simultaneously by grid build-out, industrial electrification, and the explosive growth of AI infrastructure. The episode closes on the trade-offs that follow from that reality, from financing hard-tech mining solutions to building companies in sectors where the need is obvious, the customers are conservative, and proof matters more than hype.

    Bigger turbines, bigger consequences: how wind is rethinking risk, insurance, and predictive maintenance

    Wind remains fundamentally healthy: electricity demand is rising, decarbonised power is still needed, and both Europe and the US continue to pull new projects forward, albeit for different reasons. But the industry’s center of gravity is shifting. The conversation is no longer just about building faster or installing more megawatts. As turbines get larger, OEM competition broadens, and project economics tighten, the consequences of failure are becoming much harder to ignore. Host Sylvia Leyva Martinez is joined by Alexis Grenon, CEO of Onyx Insight, and Olly Litterick of Tokio Marine GX to examine what that shift means in practice. Their core argument is that the wind sector is moving from a development-at-speed mindset toward operational efficiency, where every dollar of ROI matters and risk has to be quantified far more precisely. They unpack why insurers still struggle with newer turbine classes despite two decades of renewables underwriting: the machines are scaling faster than the loss history, the supply chain maturity is lagging  to price them confidently, and in wind, bigger hardware often means not more failures, but far costlier ones when they do occur. A large part of the discussion focuses on blades, where exposure and difficult inspection regimes make early detection especially valuable. Grenon argues that the industry has relied too heavily on periodic inspection and not enough on continuous monitoring, contrasting the lack of standardised turbine monitoring with the smoke detector logic used elsewhere in insurance. The promise of better instrumentation, integrated SCADA and condition data, and physics-informed AI is not simply smarter dashboards. It is the ability to detect structural issues earlier, prevent minor damage from escalating into six-figure or seven-figure failures, and make better-informed decisions about maintenance, underwriting, and asset life. The episode also looks ahead to the next set of decisions facing wind owners: how to handle aging fleets, when to extend life versus repower, and how much independent real-time data can change the balance of power between owners, OEMs, and insurers. The takeaway is that better data and earlier visibility can help the industry move from reactive maintenance and blunt underwriting toward a more preventative, risk-based model, one that should improve insurability, reduce downtime, and make the next phase of wind deployment more durable.
