[Episode #108] – Will Energy Transition Be Rapid or Gradual?

Nov 13 2019

Champions of energy transition see it happening relatively quickly, emphasizing the advances that are being made in technologies, policy, and projects. While fossil fuel incumbents see a long, gradual process of energy transition, assuring us that demand for their products will remain strong for decades to come. So who’s right? Is energy transition going to be rapid, or gradual?

A new paper co-authored by Carbon Tracker, Bloomberg New Energy Finance, and the Rocky Mountain Institute contrasts these narratives and scenarios, and identifies some key distinguishing characteristics that can help us understand where they differ, as well as clarifying their underlying assumptions and perspectives, using those insights to inform our outlooks. In this episode, one of the authors from Carbon Tracker explains the analytical framework applied to these contrasting narratives, and shares his insights about the impact of the energy transition on financial markets, domestic politics and geopolitics, and how incumbents will have to navigate the new reality of climate change.

[Episode #106] – Transition in South Africa

Oct 16 2019

Mini Episode

South Africa is one of the most coal-dependent countries in the world, with abundant (if low-grade) coal resources, a grid that is almost entirely powered by coal, an industrial base that is powered by coal, and a huge fiscal dependence on coal exports. And it’s debt-laden state-owned power company is not only in need of repeated bailouts, but is also now ruining the country’s credit rating. But South Africa also has excellent wind and solar resources, enabling renewable projects to easily beat coal on price. So one would think that energy transition there is a no-brainer. But the picture is actually much more complex, having more to do with politics than technology or economics.

So we turned to Jesse Burton, an energy policy researcher in the Energy Systems Research group at the University of Cape Town and a senior associate at the London-based think tank E3G to help us understand the current reality, and the future potential, of energy in South Africa. Join us as she leads us on a fascinating tour of a country that has one of the highest proportional carbon footprints today, but could be the poster child of energy transition in the future.

[Episode #97] – How State Policies Can Drive Decarbonization

Jun 12 2019

Mini Episode

As we continue looking for ways to decarbonize our energy systems, we often have to decide whether it’s better to try reworking our market rules so that the markets will do a better job of procuring clean energy, as we discussed in Episode #90, or whether it makes sense to just mandate the procurement of clean energy resources. The former is a job for the Federal Energy Regulatory Commission (FERC), but the latter is the domain of the states. In fact, our guest in this episode, a senior attorney with NRDC and the Sustainable FERC Project, argues that because states are really the only ones with the authority to regulate energy in order to obtain a more environmentally beneficial outcome and combat climate change, their mandates are a necessary pathway to decarbonizing the grid. And that, to some extent, market price distortion is in the mind of the beholder.

[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!
