[Episode #246] – Meeting Australia’s 2030 Target

Mar 26 2025

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

In late 2024, Chris traveled to Australia and recorded interviews with a wide range of experts who are closely involved in its energy transition. The first of those interviews was featured in Episode #234, and the second in Episode #235.

In this episode, we'll see how the Australian government is working with the grid power sector to plan and execute its transition to renewables—despite a political opposition committed to fossil fuels and nuclear. We'll also explore what's being done to ensure adequate capacity and maintain system reliability during this transformation.

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

Chris Bowen, Minister for Climate Change and Energy for the Australian Labor Party, explains Australia's decarbonization targets and the government's framework to achieve them.
Matt Kean, Chair of Australia's Climate Change Authority, shares his team’s findings about the best pathways to meet those targets.
Alex Wonhas of AMPYR shares insights from helping grid operator AEMO develop Integrated System Plans that describe how to evolve the system toward those targets while maintaining reliability.
Tristan Edis of Green Energy Markets discusses the technical considerations of orchestrating new grid power resources.

In the subsequent episodes in this miniseries, we’ll be exploring how Australia is using innovation to meet the challenges of the transition. We’ll also take a closer look at how they use DER integration to support the system while helping customers gain more control over their energy bills and even save money.

[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.

Guest:

Robert Margolis is a Senior Energy Analyst in NREL’s Strategic Energy Analysis Center. Since joining NREL in 2003, he has served as key advisor to the U.S. DOE’s Solar Energy Technologies Office. In this role he has helped to define and carry out a broad analytical agenda focused on examining the potential for and challenges related to wide-spread adoption of solar energy. He led the Solar Futures Study (2021), the On the Path to SunShot Study (2016), and the SunShot Vision Study (2021). His main research interests include energy technology and policy; research, development, and demonstration policy; and energy-economic-environmental modeling.

[Episode #197] – Virtual Power Plants (VPPs)

May 3 2023

Full Episode

The time may have arrived for Virtual Power Plants (VPPs) to fully realize their potential. In a VPP, groups of distributed energy resources (DERs) like EVs, batteries, and heat pumps can be managed to consume power when it is inexpensive, avoid consuming power when it is expensive, and even provide power back to the grid when supplies are limited.

While VPPs have been around for many years, operating commercially in places like Australia, the US power grid has not seen wide-scale integration. This is now changing because VPPs can help the grid do more with less - supporting new loads without requiring expensive new investments in grid expansion.

In this episode, Jigar Shah, Director of the Loan Programs Office at the US Department of Energy, joins us to share his vision of a much-expanded role for VPPs on the power grid and why he thinks the sector is ready to scale up. You’ll hear how a handful of VPPs and programs to support them have been launched in the US. You’ll also hear how the US Department of Energy is exploring ways to accelerate the development and integration of VPPs, including making financing available through Jigar’s office to support the adoption of VPP-enabled DERs under the Title 17 Clean Energy Financing program.

And because Jigar is with the Department of Energy, sharing information that should be accessible to everyone, we decided to make this one of our occasional lagniappe shows and put it in front of the paywall so that premium and free listeners alike can enjoy it. Hey free listeners, now you can see what you’ve been missing!

[Episode #150] – Resilient and Reliable Power

Jun 23 2021

Mini Episode

As areas like California and Texas struggle amid wildfires, extreme freezes, high winds and other challenges, and take measures to keep the lights on, it’s worth pausing to consider what “resilient” and “reliable” grid power means from the perspective of grid planning. What, specifically, should the operators of the bulk power system do to make their grids more reliable? Do wholesale power markets need to be reformed, to internalize the costs of power shutoffs and send price signals that project developers can respond to? How can new technologies, like demand response systems and microgrids, play new roles in making grids more resilient? And at an even more fundamental level… who is the grid for, anyway? Does the grid exist to serve people, or do people exist to serve the grid?

Energy Transition Show regular Lorenzo Kristov, a grid architect of over 20 years’ experience, has been thinking deeply about these questions and shares his thoughts with us in this episode. Inverting the usual logic of grid planning, he suggests that more active participation by customers and distributed energy resources can help improve both grid resilience and reliability, while democratizing grid power and grid governance. This thoughtful, heady interview will leave even veteran grid experts with more than a few new ideas to consider!

[Episode #94] – Integrated Decentralized Power Systems

May 1 2019

Mini Episode

As more distributed energy resources arrive unbidden onto the power grid, they are increasingly requiring us not to just think about new utility business models, but to radically rethink what a utility might look like. What if millions of distributed resources become the dominant resources, and the grid assumes a subordinate role as a residual supplier of energy? What if the control of the system is also decentralized, through the actions of millions of devices? What if the roles of transmission system operators and the distribution system are diminished as their responsibilities are distributed across all those devices? And how will utilities, power market operators, regulators, legislators, and local officials deal with a radical shift in their roles and responsibilities? These are the questions that our guest in this episode—an 18-year veteran of wholesale power market design at the California ISO—thinks about, and he shares those deep thoughts with us in this wonky yet heady discussion.
