CAISO Battery Scorecard: Who’s Winning, and Who’s Losing?

Synopsis

This session explores performance of individual battery energy storage systems (BESS) in CAISO, highlighting variation in revenue outcomes within the fleet and across market regions. We’ll compare actual revenue versus modeled market opportunity for individual BESS assets, revealing key drivers of performance gaps. We’ll also examine how differing market rules in CAISO and ERCOT shape operational strategies and ultimately impact asset returns.

• Why some BESS consistently outperform others
• How to evaluate asset-level performance in context of opportunity vs. actual results
• The impact of market design and participation rules on value capture
• Strategies for improving returns in an increasingly competitive storage landscape

This session is ideal for asset owners, operators, and investors seeking a deeper understanding of performance optimization of BESS assets.
