    Secret Supplier, BESS Arbitrage & Scaling Large-Scale Storage - with Daniel Jaksic, Sunwoda S2E27

    Who actually manufactures the batteries powering the world's most dominant tech and EV brands, and how are those same cells revolutionizing utility-scale grid storage in Australia? In this episode, we sit down with Daniel, Business Development Manager for Sunwoda (one of the world's largest, vertically integrated battery manufacturers).  Starting as a communications engineer who barely scraped a 55% passing grade, Daniel went on to acquire a sponsored MBA and build a massive career in HV technical sales and utility infrastructure. We go deep into the sheer scale of the Chinese battery manufacturing ecosystem, how developers have completely shifted from standalone solar to BESS (Battery Energy Storage System) arbitrage projects, and why the grid is desperate for storage solutions.  Daniel also breaks down how Sunwoda doubled their 20ft container capacity in less than two years (from 2.7MWh to 5MWh, and soon 6.3MWh), their strict R&D integration testing with tier-one European inverters, and his personal journey building a fully off-grid cabin from scratch in the Queensland hinterlands. What we cover: ✅ Why passing an engineering degree with 55% isn't the end of the world ✅ The immense power of an MBA in understanding business drivers and technical sales ✅ Going completely off-grid: sourcing tier-two standalone systems ✅ The pivot from legacy coal, gas transmission lines to large-scale PV and BESS connections ✅ Why Australian developers are abandoning standalone PV for pure arbitrage battery farms ✅ Sunwoda’s massive scale: 80,000 global staff, 14 factories, manufacturing their own cells ✅ The truth about consumer batteries: Sunwoda’s 20-year history supplying Apple and Tesla ✅ Solving extreme temperature derating for BESS sites in the Australian outback ✅ Replacing diesel generators with hybrid microgrids on remote Australian mining sites

    Data Center Grid Crisis, Wind Energy & Consumer Advocacy - with Craig Memery S2E26

    What happens when the insatiable energy demands of massive data centres collide with an aging grid, and who is actually standing up for the everyday person paying the bills? In this episode, we sit down with Craig Memery: a leading energy advocate and renewable energy veteran: to unpack the complex realities of the Australian energy transition.  From his early days climbing 80-metre wind testing towers and developing standalone power systems, to his critical work with the Justice and Equity Centre and the Alternative Technology Association (now Renew), Craig brings a deeply human perspective to a highly technical industry. We go deep into the philosophy of consumer advocacy, why energy efficiency remains the most overlooked solution to our grid crisis, and the massive incoming threat (and opportunity) posed by data centers.  Craig also breaks down the transition from mechanical inertia (synchronous condensers) to grid-scale batteries, and how network tariffs must evolve to avoid unfairly punishing renters and vulnerable households. ⚡ What we cover: ✅ Why the term 'consumer' dehumanizes people in the energy transition ✅ The forgotten potential of passive solar design and household energy efficiency ✅ Early wind farm prospecting and overcoming a fear of heights on 80m test towers ✅ The massive grid impact of new data centers and why they avoid deeper network costs ✅ How to co-optimize data center loads using demand response and optionality ✅ The structural flaws in volumetric network tariffs and high fixed charges ✅ Transitioning from synchronous condensers to advanced grid-scale batteries ✅ The psychological benefits of silent meditation retreats for complex problem-solving

    Data Visualisation, Radar Engineering & The Reality of Solar Comms - with Chris Martell S2E24

    What happens when defence-grade software analytics meets renewable infrastructure, and why is 30% of commercial solar offline right now? In this episode, we sit down with Chris Martell: Managing Director of GSES (Global Sustainable Energy Solutions): to explore solar engineering, training evolution, and advanced asset management. Chris shares his journey from working on military radar arrays at Raytheon in Boston to leading one of Australia's most respected renewable energy consulting and training institutions, GSES.  We discuss the technical challenges of early commercial solar, engineering car park canopy arrays over active easements, and the launch of Mindaro for large-scale microgrid engineering. We also explore Diagno, a machine-learning data visualization platform built in partnership with UNSW and UTS to automate fault detection. Chris breaks down the massive industry-wide failure in communications, the lack of structured O&M programs, and how the solar sector must adapt as systems integrate into virtual power plants (VPPs). What we cover: ✅ Chris's transition from defence systems engineering to terrestrial solar photovoltaics ✅ The legacy of UNSW and Martin Green in pioneering modern cell efficiency records ✅ Inside early commercial solar deployments and complex grid connection architectures ✅ Designing bespoke solar canopy structures over commercial easements ✅ The scaling of GSES from an international aid consultancy to an industry-standard RTO ✅ How Mindaro spun out to handle utility-scale designs up to 150MW plus ✅ The technical birth of Diagno and utilizing cloud APIs for data cleaning and normalization ✅ Why 30% of solar asset communications are down at any given moment  ✅ Building structured O&M frameworks with defined SLAs for high-value asset owners ✅ The true potential of alternative storage mediums including flywheels and mechanical storage ✅ Expanding clean energy skills training across developing nations like the Philippines and Pakistan

    Politics, Environment & Brutal Honesty - with Nick McGowan S2E23

    What does honest politics actually sound like? In this episode, we sit down with Nick McGowan,  Victorian MP, Shadow Minister for Environment, and Shadow Minister for Fire Services, for one of the most open, direct, and thought-provoking conversations we’ve had on the podcast. Nick shares his journey from knowing in grade five that he wanted to be a member of parliament, to standing for council at 18, working in politics, serving with the United Nations in conflict-affected regions, and now tackling environmental issues here in Victoria. But this conversation goes well beyond party politics! We cover leadership, public service, trust, respect, tribalism, education, community, renewable energy, environmental protection, PFAS, waste, invasive species, and why Australia can still lead by example.
