[Episode #204] – Regulatory Reform

Aug 9 2023

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.

[Episode #87] – The Value of Flexible Solar

Jan 23 2019

Mini Episode

As variable renewables gain ever-larger shares of the grid power supply mix, integrating them on the grid is raising new questions about the best ways to do it. Storage systems are one obvious answer, but their deployment as utility-scale assets is still in the early days. Right now, if a utility-scale solar plant is producing more power than the grid can use, and there isn’t a storage system available to absorb the excess, the standard procedure is to curtail the plant — just turn it off. It hurts the revenues of plant owners, but at least it won’t damage the grid.

But now there are some new ways to the problem of integrating more variable renewables: Make them flexible! Instead of always running wind and solar plants full bore, or curtailing them, just turn them down a bit. Or make them completely flexible, able to ramp up and down at will, after deliberately providing enough room on their host grids to allow that.

Our guest in this episode is an expert on the subject who has helped the California Independent System Operator, or CAISO, think about new, flexible modes of operation for solar plants. It’s a very geeky and oftentimes technical interview, but we know the grid geeks who listen to this show will love it!

[Episode #41] – Generator Survival Strategies

Apr 19 2017

Mini Episode

Owners of old nuclear and coal power generation in the US are on the ropes, because their plants can’t compete with cheaper natural gas and renewables. Some—especially those operating in competitive markets—are simply shutting down, while others are trying a whole host of survival strategies: seeking special payments and subsidies, “around-market reforms,” and even getting states to give up on competitive generation markets and go back to the old regulated utility business. So what are the pros and cons of these strategies, and what are the implications for consumers and for energy transition as a whole? Gavin Bade, an editor at Utility Dive who has written extensively on these topics, leads us through a tangle of legal, technical, and economic implications toward a more clear-eyed picture of how incumbent generators are trying to survive the transition.

[eLab Extra #3] – Grid Modernization and DERPs

Jan 4 2017

Full Episode

This is a special, free "extra" episode recorded at RMI’s eLab Annual Summit in December 2016 in Austin, Texas.

Grid architecture is evolving, with loads becoming increasingly indistinguishable from generators, and local generators and other distributed resources increasingly supplying the services that were always provided by large central generators in the past. Meanwhile, an ever-evolving set of regulations for wholesale market operations is both enabling new market participants and challenging the security of old market participants. Lorenzo Kristov of the California Independent System Operator returns to the Energy Transition Show to share more of his view of the future in an interview from RMI’s eLab Annual Summit 2016.

[eLab Extra #2] – Hawaii’s Energy Transition

Jan 4 2017

Full Episode

This is a special, free "extra" episode recorded at RMI’s eLab Annual Summit in December 2016 in Austin, Texas.

How is Hawaii managing one of the most rapid energy transitions in history to variable wind and solar generators, while maintaining a balanced, isolated grid and actually reducing long-term costs? It’s no accident: They have developed a transition roadmap and they are working hard to adopt the latest technology while preserving social equity…not just for grid power, but for electric vehicles as well, toward a goal of reaching 100% renewable electricity by 2045. Lorraine Akiba of the Hawaii PUC shares her perspective in an interview from RMI’s eLab Annual Summit 2016.
