[Episode #251] – South Australia on Point

Jun 4 2025

Mini Episode

This episode is the final part in our miniseries about Australia's energy transition.

In late 2024, Chris traveled to Australia and recorded interviews with a wide range of experts who are intimately involved in the energy transition there. We featured some of them in the earlier episodes of this miniseries, namely, Episodes #234, #235, #246, #247, and #249.

In this episode, we take a close look at South Australia, where rooftop solar alone already powers the entire state grid at times. By 2027, South Australia plans to operate with 100% variable renewable energy, making it the first gigawatt-scale grid in the world to achieve this milestone.

The challenge? SA Power Networks, the distribution grid operator, doesn't control generation, transmission, or metering, and doesn't buy or sell electricity. This means South Australia must figure out how to maintain a stable, reliable grid consisting largely of customer-owned energy resources.

In this conversation, James Brown, Head of Network Strategy at SA Power Networks, explains how his team of engineers and stakeholders are finding innovative solutions to meet this challenge. Their approaches will offer valuable lessons for grids worldwide as they, too, transition to electricity systems almost entirely powered by variable renewables.

Guest:

James Brown is Head of Network Strategy for SA Power Networks. James is responsible for facilitation and oversight of long-term strategy to ensure that the network, and the services it delivers, adapt to changing environmental factors.

James has over 10 years’ experience delivering world-leading strategy and innovation in the energy sector. His current role is leading the Network Strategy team at SA Power Networks’ Network Innovation Centre, responsible for pilots, trials and major programs of work that are shaping the distributed energy future.

[Episode #245] – Evolving the UK Energy System Part 3

Mar 12 2025

Mini Episode

In the first part, Episode #240, we reviewed the UK's unique strategies for procuring energy transition solutions. In the second part, Episode #241, we covered how the nation’s energy regulator is driving investment to support the transition.

To conclude this miniseries, we welcome back Julian Leslie, who first joined us in Episode #174. Julian is now Director of Strategic Energy Planning and Chief Engineer at Britain’s National Energy System Operator (NESO), a recently-created agency tasked with preparing Great Britain's electricity network for net zero operation by 2030. He also coordinates regional and national plans for Britain’s energy system—including gas and emerging heat networks—to meet decarbonization targets.

In this conversation, we review the progress of the innovative Pathfinder programs we discussed back in 2022, which invited the market to provide solutions that could help Britain integrate more wind and solar into its grid. We walk through the extensive process that NESO is undertaking to plan and coordinate the development of a fully decarbonized power grid by 2030. And we discuss in detail how Britain is working to massively expand its capacity in offshore and onshore wind, solar, transmission, and battery storage to meet that goal.

By setting clear decarbonization targets, then collaborating with industry and stakeholders to carry out plans to meet them, the UK is showing the world how to execute a successful energy transition. We hope this miniseries inspires other nations to follow their example.

[Episode #242] – IEA Outlook 2025

Jan 29 2025

Mini Episode

What important trends are shaping the energy transition today? And what is the outlook for oil and gas demand?

In this conversation, Tim Gould of the International Energy Agency (IEA) returns to discuss key insights from the agency’s flagship annual report, the World Energy Outlook 2024. We consider the enormous implications of IEA’s view that global demand for all fossil fuels will peak and begin a slow decline within the next five years. To explore this, we take a closer look at the state of the oil and gas industry, comparing its expectations to what climate science and energy system modeling tell us about the future of fossil fuels. We also consider how the energy transition could reduce overall demand for fossil fuels, creating excess supply imbalances that reshape global markets and trade geopolitics.

Our discussion also touches on the IEA’s forecast that low-emission electricity sources like solar, wind, and nuclear will account for more than half of global power generation before 2030. Further, we explore the rising energy demand from data centers, shifting expectations for hydrogen, and the investments needed to keep clean energy growing at a pace that meets our climate targets.

Guest:

Tim Gould is co-head of the World Energy Outlook series at the Paris-based International Energy Agency (IEA).

[Episode #240] – Evolving the UK Energy System Part 1

Jan 1 2025

Mini Episode

This episode kicks off a new miniseries exploring how the UK is evolving its energy system through world-leading efforts to meet its decarbonization goals. In 2024, it closed its last coal-fired power plant and conducted its most successful Contract for Difference (CfD) auction yet, which attracted a diverse range of renewable energy projects—including more than enough offshore wind bids to make up for the lack of such projects in the 2023 auction.

The UK also launched an astonishingly ambitious effort to develop an economy-wide energy planning process for the entire country, conducted by the newly-established National Energy System Operator (or NESO). NESO produced its first report, providing essential guidance to all participants in the country’s energy system. Additionally, Great British Energy was created, which will make the British government a direct investor in renewable energy projects.

In this episode, we speak with Adam Berman, the Director of Policy and Advocacy at Energy UK, the nation’s energy industry trade group. He advocates for ways to speed up the UK’s journey to net-zero through enabling low-carbon investment in clean power generation. We review all of 2024’s developments in detail, and outline the path forward for the UK’s energy transition.

[Episode #229] – US Distributed Solar Potential

Jul 24 2024

Mini Episode

What is the full potential for distributed solar power in the US?

Many models have been developed to explore how a decarbonized US energy system could look, consistently finding that solar power would be the dominant source of electricity. Yet, we don’t really know the full potential for distributed solar. Even the term “distributed solar” isn’t very well-defined, potentially referring to many different kinds of solar power installations.

In today’s conversation, we review the available estimates for small rooftop and ground-mounted systems typically found on buildings, solar panels on canopies over parking lots, and innovative floating solar arrays over bodies of freshwater. Additionally, we explore emerging options such as installations on brownfield sites, agricultural lands, and alongside roadways.

Then we add it all up to see how big of a role distributed solar could actually play in a fully decarbonized US electricity system—with a surprisingly large result! But you’ll have to be a premium member and listen to the end to find out what it is.

In this episode, we are joined by Robert Margolis, a Senior Energy Analyst with the Strategic Energy Analysis Center at the National Renewable Energy Laboratory (or NREL), which is part of the US Department of Energy. With more than 20 years of focused research on solar in the US, and his deep familiarity with energy technology and policy and energy-economic-environmental modeling, he is one of the top experts on the potential for distributed solar in the US.
