About this listen

Clean tech, green finance and energy innovation are the three lanes on the road to a successful global energy transition. At the intersection of these lanes is a place where ideas on finance, technology and policy are shared and debated. That intersection is Interchange Recharged.

While Sylvia Leyva Martinez, principal analyst at Wood Mackenzie, is on maternity leave, Bridget van Dorsten, a principal analyst on Wood Mackenzie's hydrogen team, will be hosting this podcast, Interchange Recharged. When Bridget is not researching global market dynamics to craft near and long-term forecasts for low-carbon hydrogen and its derivatives she is speaking with visionaries, entrepreneurs, policy-makers and energy analysts to explore the newest developments in renewable technology, explain the ideas on global energy policy that could accelerate the energy transition, and identify new funding and financial models that could solve the biggest challenges we face on the way to net zero.

Bridget and her guests bring you data and forecasts on clean technology, climate science, and offer predictions on the build out of utility-scale projects and the future of green finance.

What impacts do the annual UN Conference of the Parties have on decarbonisation goals and climate change? What will COP30 bring? What’s happening in global EV adoption and development? What’s the forecast for solar energy, one of the major success stories of renewable energy in the last ten years? What does the data tell us about the future of hydrogen, of nuclear, or of low-carbon power? These are examples of the insights and detailed analyses you can expect bi-weekly on Tuesdays at 7am ET.

  • Flexibility as a service: Can Octopus's acquisition of Uplight finally make US residential VPPs work?
    Apr 7 2026

    Millions of enrolled devices, 60 utilities, and the participation rate gap that's been embarrassing the US market for a decade.

    US residential virtual power plants have been a promising idea that's consistently underdelivered — participation rates below 5%, fragmented apps, siloed programmes, and utilities that have simply never had to compete for a customer's attention. Meanwhile, Octopus Energy has built the world's largest residential VPP in the UK, with EV driver participation rates of 50 to 70%. The question has always been whether that model can travel to a market where most customers have no supplier choice at all.

    Bridget van Dorsten speaks with Nick Chaset, CEO of Octopus Energy US, about the acquisition that represents Octopus's biggest bet on answering that question: a majority stake in Uplight alongside Schneider Electric, giving Octopus access to established relationships with more than 60 US utilities — including eight of the ten largest.

    Nick argues the participation gap isn't really a cultural problem or a technology problem. It's a regulatory design problem. US flexibility programmes have been built device by device, forcing consumers to juggle multiple apps and enrolments — and in some cases prohibiting them from combining assets across programmes. Octopus's answer is one app, a 30-second sign-up, and a value proposition framed entirely around what consumers actually care about: lower bills. Can that translate through a utility partnership channel rather than a direct retail relationship?

    The conversation also tackles the data centre dimension. Nick makes the case that residential flexibility isn't a separate story from the large load interconnection challenge — it's part of the solution. If utilities can statistically guarantee load reductions from tens of thousands of enrolled homes during peak hours, they may be able to connect larger data centre loads at smaller interconnection points. And in many hours when a data centre might otherwise ramp down, it could simply be cheaper to pay consumers to flex instead.

    Octopus's model is built on trust earned through direct consumer relationships. Can that translate through a utility intermediary at scale, across 60 different utility cultures without losing what makes it work?

  • The muscle we forgot: SMRs, hyperscalers, and why this nuclear renaissance might actually be different
    Mar 24 2026

    Why nuclear has never been project financed and how that might finally be about to change.

    Every nuclear plant ever built has ultimately been backstopped by taxpayers or ratepayers. Not because the technology doesn't work, but because nobody has ever cracked the construction cost and schedule problem well enough to convince a bank to finance it without government support. Bridget van Dorsten is joined by Jake Jurewicz, Co-founder and CEO of Blue Energy, to explore why that has been so hard and what a credible path to fixing it might actually look like.

    Jake walks through the root cause of nuclear's cost overrun problem and it is not the reactor. The reactor equipment itself represents around 7% of total project costs. The real problem is what Jake calls nuclear construction overhead: the cost of mobilizing, training, and retaining the 10,000 or so skilled workers needed to build these plants in the field, the way we have been building them for 70 years, essentially the same way you would build a castle.

    The episode then turns to what Blue Energy is doing differently. By intentionally selecting sites accessible by barge and contracting existing oil and gas fabrication yards and shipyards to build large pre-assembled modules offsite, Blue Energy aims to bring fixed-price contracts into nuclear for the first time, the same contracting structure that made offshore wind and LNG bankable. Jake explains why that single shift changes everything for project financing.

    Bridget and Jake also work through the demand side of the equation: why hyperscalers are becoming the crucial beachhead market for new nuclear, what binding PPAs from investment-grade counterparties actually signal versus announcements, and why the restarts and uprates, while valuable, only go so far.

    The conversation also covers Blue Energy's first announced project at the Port of Victoria in Texas, a 1.5 gigawatt nuclear-powered AI data centre co-located with a gas-to-nuclear conversion, designed to accelerate commercial operation and reduce cost of capital even without government loan support. Jake explains the mechanics of why firing the balance of plant with gas first before switching to nuclear steam is not a compromise but a genuine financing innovation.

    Finally, Jake offers a view of what signals actually matter when separating the nuclear renaissance from the noise: binding PPAs, large balance sheets standing behind fixed-price contracts, and projects moving through the Nuclear Regulatory Commission rather than staying at the prototype stage.

  • The grid nobody planned for: public power, hyperscalers and the race to rewire America for the AI age
    Mar 10 2026

    What two decades of flat demand means for a grid now expected to double in size


    The US went from essentially zero load growth for twenty years to 3% national growth almost overnight. The supply chains, permitting pipelines, engineering workforce and regulatory processes were all calibrated for a different world. Bridget van Dorsten is joined by Tom Falcone, President of the Large Public Power Council, representing the 30 largest publicly owned utilities in the United States, collectively owning around 85% of public power assets and currently serving roughly 18% of all US data centre load.

    Tom explains what makes public power structurally different from investor-owned utilities: locally governed, not-for-profit, and built to minimise cost rather than earn a return on equity. That governance model turns out to matter a great deal when trillion-dollar hyperscalers come looking for power. Public power utilities have no financial incentive to favour their own assets over a customer's, and their local accountability makes deal-making faster and more direct.

    Bridget and Tom also work through the mechanics of how the industry is actually responding. Large-load tariffs are reshaping the interconnection queue, forcing hyperscalers to make long-term financial commitments rather than reserving capacity for free. About two thirds of speculative requests disappear once real commitments are required, which tells you something about the gap between announced demand and real demand. LPPC members are nonetheless planning to add around 60GW of new generation over the next ten years to meet load that is forecast to grow from 4GW to 18GW of data centres in their territories alone, in just five years.

    The episode also tackles private use rules, a Treasury regulation from 25 years ago that nobody expected to become a bottleneck for the AI era, the capacity factor realities that make peak-day power so much harder to deliver than annual energy, the nuclear question and why federal involvement is probably unavoidable if the US wants to build at scale, and where CCS can and cannot realistically be deployed.
