[Episode #161] – Expanding Transmission

Dec 8 2021

It has been nearly impossible to get new transmission built across the US in recent years, thanks to a combination of local opposition from host communities, jurisdictional issues, and the resistance of major utilities, alongside other factors. But with the Infrastructure Investment and Jobs Act (previously known as the Bipartisan Infrastructure Bill) now committed to law, there are fresh hopes that new transmission lines can be built in the US to unlock the truly massive renewable resources that are currently unable to get to market… resources that are critical to helping the US decarbonize its economy. There are also new techniques for building transmission, and potentially new regulations that can overcome resistance to new lines.

In this episode, we revisit the topic of transmission and see what needs to happen to get new transmission projects moving in the US. We also ask whether a macro grid based on big transmission lines is still really the cheapest and best solution, or if more distributed solutions might be worth reevaluating in light of updated cost data and some contemporary grid modeling.

Our guest in this episode is Liza Reed, the research manager for low carbon technology policy at the Niskanen Center in Washington, D.C., an expert in High Voltage Direct Current, electricity transmission, and technology innovation. She shares with us the latest thinking about transmission, and helps us tie together some of the threads we have discussed in previous episodes, to paint a picture of how more transmission can bring hundreds of gigawatts of renewable power to market in the US.

[Episode #70] – Who Should Control Wholesale Markets?

May 30 2018

Mini Episode

As older coal and nuclear generators are pushed off the grid by cheaper, nimbler, cleaner renewables and other technologies, the owners of conventional generators are becoming increasingly nervous about their futures, and seeking new ways to protect their legacy assets. From attempting to change market rules or simply pursuing new subsidies, the effort to retire dirty and unwanted old generators and replace them with newer, cleaner sources of electricity faces a series of challenges. And how those challenges are resolved will have broad implications for how the electric grid of the future will operate, and who will own it.

In this episode we take a deep dive into the intersections between federal authority, wholesale markets, and state policies, explore some of the legal questions therein, and try to understand what they suggest about the process of energy transition, and the pathways for unlocking new ways of using energy and designing electricity markets…and yes, this episode definitely deserves its Geek Rating!
