Inside the ‘crazy grid’

Building out the electricity grid was traditionally a predictable and straightforward business. Now it’s like trying to land a jet on a moving aircraft carrier in the dark. That’s a quote from this week’s guest Quinn Nakayama. He’s the senior director of Grid Research and Innovation at Pacific Gas & Electric (PG&E). He joins host Ed Crooks and regular guest Amy Myers Jaffe to discuss how California is dealing with all the uncertainty created by new demands being placed on the grid: variable renewable generation, electric vehicles, data centres, and more. 

Quinn refers to the fast-changing electricity system of today as the ‘crazy grid’, because so many things are happening at once. Wind and solar power create new challenges for grid stability, while batteries and demand response offer new solutions. Electric vehicles, following mandates from the state of California and other governments around the world, create new patterns of electricity consumption. The latest breakthroughs in AI are creating a surge in power demand from data centres. And those advances in AI are also opening up new possibilities for grid management. 

Planning is harder than ever. Are Virtual Power Plants (VPPs) an important solution? Amy, Ed and Quinn debate their effectiveness; these tools are helpful, but they can't solve everything. Large loads such as data centres still need major upgrades to wires and substations. But with a high penetration of electric vehicles, California is working on smart tech that makes it easier to install EV chargers without expensive upgrades. PG&E is also exploring faster ways to connect large users, such as allowing temporary solutions until new lines are built.

Despite the range of innovations that are available, and the exciting rate of progress in new technologies, the US risks falling behind other countries. Quinn and Amy warn that cuts in support for clean energy and EVs could lead to the US losing out to China, which is investing heavily in these technologies.

The Reconciliation Bill that was signed into law last week included abrupt curtailments of tax credits for wind and solar power. So, what is the right way forward for the grid? For the electricity system to meet the fast-evolving demands of the modern world, it needs everything: more energy, more flexibility, and faster action.
