PJM and ERCOT navigate a capacity rollercoaster
Catalyst with Shayle Kann
Intro
Shayle Kann introduces the episode, guest Paul Siegel, and sponsors, setting up a discussion on PJM and ERCOT capacity dynamics.
Last year, the PJM capacity crunch became a focal point for an entire industry struggling to navigate the explosive growth of hyperscaler data centers. Yet even in the first two months of 2026, capacity prices have continued to skyrocket, and the economics of energy generation have only become more tenuous.
In this episode, Shayle Kann talks to Paul Segal, the CEO of LS Power. A major player in the space, LS Power owns a diverse portfolio of generation, storage, and transmission assets across the U.S.
Shayle and Paul dive into the volatility currently defining the two most talked-about power markets in the country: PJM and ERCOT. They cover topics like:
How PJM flipped nearly overnight from a state of "stasis" to a capacity shortage
The federal government's emergency order to make large data centers "pay their way"
Why 10 gigawatts of expected load failed to show up during the recent Texas winter storm
Why Paul sees ERCOT as a “cyclical” market that is currently difficult for new gas generation, despite massive load growth
Paul’s strategy for ensuring sufficient “bridge” generation before new large-scale projects come online
