[Episode #247] – Energy Innovations in Australia

Apr 9 2025

This episode is part of a miniseries about Australia's energy transition.

In late 2024, Chris traveled to Australia and recorded interviews with experts closely involved in its energy transition. The first of those interviews was featured in Episode #234, and the second in Episode #235. In Episode #246, we explored how the Australian government is working with the grid power sector to plan its transition to renewables while maintaining system reliability.

In this episode, we explore innovative approaches Australia is using to manage the evolution of its energy system.

To tell this part of the story, we weave together the perspectives of several guests:

Darren Miller, CEO of ARENA, explains their investment focus on early-stage technologies.
Gabrielle Kuiper, energy and climate change professional, shares insights on DER integration across Australia.
Stephanie Unwin, CEO of Horizon Power, discusses the unique challenges of managing a remote utility in Western Australia.
Professor John Boland describes how he and his wife used low-tech solutions to transform an uncomfortable old house into a comfortable urban oasis.

In the next miniseries episodes, we'll explore more innovations in solar power and take a close look at how one Australian state is solving the challenges of knitting together customer-owned systems into a reliable power grid.

[Episode #209] – End of the Nuclear Age

Oct 18 2023

Mini Episode

If we genuinely need nuclear power—be it older conventional designs or new, unproven small modular designs—to make the energy transition a success, then that case has not been demonstrated. Instead, nuclear advocates have primarily used political argument to support continued investment in it. Because if we just went by the industry’s actual track record, and properly internalized its risks and high costs, we’d never build another nuclear power plant again.

Nuclear power never had a proper justification as an electricity generation technology. It is an industry built on a foundation of lies, extravagance, conceit, and failure. It always has been, and continues to be, a fig leaf for the nuclear weapons industry.

The fact is that we do not need nuclear power to make the energy transition a success. Even if we did continue to invest in it and force the public to shoulder its actual risks and excessive costs, doing so could actually hinder the energy transition, not advance it.

Our guest in this episode, Stephanie Cooke, has literally written the book on the untold history of nuclear power. As the former editor of Nuclear Intelligence Weekly and the author of In Mortal Hands: A Cautionary History of the Nuclear Age, she brings over four decades of experience as a professional nuclear industry journalist. She explains why, contra the recent pro-nuclear sentiment captivating climate hawks, the nuclear power industry is not at the dawning of a new age, but rather at the end of its old age.

[Episode #205] – Rebuilding the Grid from the Bottom-up

Aug 23 2023

Mini Episode

A tsunami of distributed energy resources (DERs) is starting to arrive on the grid. Customers are adopting millions of EVs, rooftop solar systems, battery backup units, and other devices that can dynamically respond to grid conditions. But most utilities are not engaging with this wave proactively. Instead, they’re being reactive, slow, and even resistant to allowing these devices to connect to the grid or participate in transactions.

As we rebuild and transform the grid in the course of the energy transition, we really need to think about how to accommodate DERs. There are manifold reasons to build a decentralized grid from the bottom-up, instead of keeping the conventional, top-down, hub-and-spoke architecture based on the large centralized power plants that we have relied upon in the past. So how do we do it?

Lorenzo Kristov has been agitating for this new architecture for years, frequently issuing white papers and expert testimony to get regulators and others thinking about what the future grid should look like. And his ideas are being taken seriously, because he was a lead designer of the locational marginal pricing (LMP) market on which California’s wholesale power system operates. He has deep expertise in wholesale market design, DER participation in wholesale markets, coordination of transmission-distribution system operations, distribution system operator (DSO) models, distribution-level markets, microgrids, energy resilience strategies, and whole-system grid architecture, among other things. And he has been walking us through his vision for the decentralized grid in previous episodes of our show: #10, #94, and #150.

In today’s episode, Lorenzo rejoins us to build on our previous conversations and share his latest thinking about how to make the new energy transition grid architecture happen. We discuss market design, architecture, procurement, regulatory issues, and related topics, making this episode deserving of a Geek Rating of 10.

[Episode #204] – Regulatory Reform

Aug 9 2023

Mini Episode

Whose job is it to lead the energy transition?

In previous episodes, we’ve talked about how markets can guide the transition, especially after targeted reforms. We’ve considered the role of regulators, and the problems of regulatory capture and corruption. We’ve asked how local community leaders and elected officials can lead the energy transition from the bottom up, and conversely, how local activists can hinder and undermine the energy transition. We’ve also looked at the role of governments, particularly where no one else seems able to meet a particular challenge, or where that challenge isn’t really anyone’s responsibility.

In this episode, we try to knit together these disparate threads with veteran regulator Audrey Zibelman, who has held senior roles at both utilities and regulatory bodies for more than 30 years. Audrey shares some deep thoughts about why regulators and governments will have to play much more creative, courageous, and ambitious roles in the future to contend with the challenges of the energy transition.
