[Episode #122] – Hybrid Power Plants

The days of worrying about the intermittency of solar and wind farms are quickly receding into the past as battery storage systems are added to existing plants, and new renewable plants are increasingly equipped with large battery storage systems from the outset as so-called “hybrid” power plants. In fact, 25% of all new solar PV plants waiting to connect to bulk power systems are now hybrid plants incorporating battery systems, and on the California wholesale power market, 96% of solar PV and 75% of wind projects launched in 2019 were paired with batteries. All at prices that beat the cost of conventional power plants.

But figuring out the best way to deploy utility-scale battery storage systems isn’t just a matter of dispatchability and system balancing. In fact, it turns out that tax credit incentives and market rules are far more significant determinants. That’s one finding of a new research paper led by several researchers at the Lawrence Berkeley National Laboratory, who modeled various ways of pairing battery storage systems with utility-scale wind and solar farms. In this episode, we explore the details of this modeling with one of the paper’s authors and speculate that it might actually be better to deploy large scale storage systems independently of wind and solar farms, if market rules were more supportive of the strategy.

[Episode #121] – Winning and Losing the Policy Game

Conventional thinking is that policy supports the advancement of clean energy gradually and progressively, with hard-won gains setting up further success over time. And sometimes, it does play out this way. But sometimes it doesn’t, too. Our guest in this episode, Dr. Leah Stokes of UC Santa Barbara, describes the policymaking around energy transition as a matter of “organized combat” between clean energy advocates and incumbents in the utility and fossil fuel sectors — a process of combat which produces winners and losers. And rather than be shy about that, she argues, advocates for climate action and energy transition need to learn from their opponents and get much more organized and serious about winning policy battles.

In this two-hour interview, we talk through the history of clean energy policymaking, and how it was rolled back or thwarted, in four U.S. states. Step by step and case by case, we can learn from her original research what the winning tactics are, and how to lock in victories when we win them. This episode is critical listening for anyone involved in policymaking, regulatory interventions, crafting legislation, or activism.

[Episode #120] – Carnage in the Oil Patch

The coronavirus shutdown has taken a huge bite out of demand for oil since everyone has been forced to stay home. Exacerbated by a pricing war between Saudi Arabia and Russia, oil prices have crashed to levels not seen in nearly two decades, and oil producers are losing money hand over fist. Not only will this oil crash have wide-ranging effects on the oil industry, it will also have huge impacts on the budgets of oil-exporting countries, the economy as a whole, and the prospects for energy transition.

Can the world get past the economic impacts of the coronavirus? If it does, will oil demand recover to previous levels, or will it be permanently reduced? Which oil producers will survive this period, and which ones will go bankrupt and be swallowed up by larger rivals? And how much market share might the rivals of oil—especially rivals like electric vehicles—pick up in the aftermath of the shutdown?

To help us sort through this incredibly complex picture, Bloomberg’s Liam Denning returns to the show for a 90-minute deep dive into oil prices, supply, demand, the outlook for the world’s producers, and the outlook for the world in this episode.

[Episode #117] – Climate Science Part 12b – Improving Climate Modeling

Are the climate change scenarios produced by the Intergovernmental Panel on Climate Change (IPCC) accurately representing our likely futures, or are they rooted in outdated data that doesn’t represent the progress we’re already making on energy transition? Is the world on a “business as usual” path to climate doom in a world that’s 5°C warmer, or are we actually within reach of limiting warming to 2°C by the end of this century?

In this episode, we ask two experts to debate these questions in the very first extended three-way conversation on this podcast. Representing the energy analyst’s critique of the IPCC models is Bloomberg New Energy Finance founder Michael Liebreich. And representing the IPCC modeling work is Dr. Nico Bauer, an integrated assessment modeler with the Potsdam Institute who has helped develop the Shared Socioeconomic Pathways used in the IPCC framework.

This episode is part two of that three-hour conversation. Part one was featured in Episode #116. Together, those two episodes make Part 12 of our mini-series on climate science.

[Episode #115] – Wildfire and Transition in Australia

Australia’s out-of-control wildfires in recent months have captured the world’s attention and raised serious questions about how climate change is affecting the continent, whether the country’s leadership is taking appropriate action to address climate risk, and what the future holds for its unique weather patterns and ecosystem.

But Australia is one of the most fossil-fuel dependent countries in the world, which makes it politically difficult to face the reality of its climate risk, and how its own activities are increasing that risk. So in this episode we invited a longtime journalist and researcher, based in Sydney, who works in research, strategy, and communications around climate change and finance, to help us understand the political, economic, and climate context of Australia at this moment, and to understand how the wildfires are influencing the trajectory of energy transition there. She reveals a country delicately balanced somewhere between hope and despair, with political leadership in thrall to the fossil fuel industry, and a populace eager to pursue energy transition and reduce its exposure to climate risk.

[Episode #114] – Cyber and Climate Risks

As energy transition progresses and more internet-connected distributed energy resources (DERs) join the grid, they increase the grid’s flexibility and dynamism, but they also expose those systems to the risk of being hacked. What kinds of protections do we need to have as grid modernization proceeds and more and more devices in the so-called “internet of things” (IoT) become part of the grid ecosystem? Should we be encouraging the adoption of smart, interconnected devices at all? Or would we be better off using devices that were not connected to communication systems in any way, to better ensure their security? And what are the relationships between cybersecurity on the grid, and the effects of climate change?

Our guest in this episode is a cybersecurity expert with the Idaho National Laboratory, part of the US Department of Energy, who provides strategic guidance on topics at the intersection of critical infrastructure security and resilience to senior U.S. and international government and industry leaders. He’s a longtime expert in this domain with a deep and wide set of relevant expertise, and you’re sure to learn a lot in this conversation about things that you probably didn’t even know existed, but that are intimately connected with grid security, climate change, and energy transition. Open your mind wide for this one – it’s a doozy!

[Episode #113] – Coal Plant Self-Scheduling

Owners of uneconomic coal plants in the US have tried many ways to keep operating, even when it is not profitable to do so, such as out-of-market subsidies and re-regulation (as we discussed in Episode #41), bailouts and wholesale market controls (as we discussed in Episode #70), and seeking capacity payments or other novel payments for alleged reliability (as we discussed in our trilogy of shows on decarbonizing power markets, Episodes #90, #97, and #105).

But there’s another tactic, variously known as “self-committing” or “self-scheduling,” and it happens when a utility that owns a coal-fired power plant elects to operate the plant no matter what the going rate for power is, even if that price is below its operating costs. Fully regulated utilities oftentimes can pass the costs of operation onto their customers even when they’re electing to run at a loss, without having to go to the trouble of asking for additional cost recovery from a regulator, or getting a legislator or wholesale market operator to give them a handout in one form or another. And it all happens more or less invisibly to customers and regulators. Only a researcher with a sharp eye and expert knowledge of what to look for would even detect these uneconomic operations, such as our guest in this episode.
