With Great Power18 Feb 2025

The Texas battery boom

Keith Collins knows electricity markets. After a stint consulting for the New York Independent System Operator, he joined FERC in 2004. After that, he spent years working for the California ISO and the Southwest Power Pool.

But it wasn’t until he joined the Electric Reliability Council of Texas (ERCOT) as vice president of commercial operations last summer that he started making waves. Unlike many electricity markets in the U.S., ERCOT is deregulated, and its grid is isolated from other systems. It drew a great deal of attention — and ire from some Texans — after a major grid failure during Winter Storm Uri back in 2021. But now, all eyes are on ERCOT as it turns to battery storage as a way to help meet surging demand for power.

This week on With Great Power, Keith explains what makes ERCOT's approach to electricity different from other markets and how the incredible growth of solar generation and battery energy storage systems have changed the Texas grid. They also cover the role of ancillary services and look ahead to how ERCOT’s energy mix will continue to evolve.
