CAISO is the largest battery storage market in the U.S., yet one of the hardest to evaluate as resources and market outcomes are anonymized. This session presents findings from Gridmatic’s CAISO Storage Report, an industry-first methodology that unmasks anonymized data to reveal how 30 real battery assets actually performed.
- Gridmatic unmasked CAISO batteries and built an industry-first proprietary shadow-clearing engine to reconstruct actual asset-level revenue
- Performance varied enormously: revenue ranged from under $1 to over $6, with the top asset earning 2.45x the median
- Location and availability explain some of the gap but not all
- Adaptive, forecast-driven bidding is what separates top performers yet many systems deploy static bidding strategies
- The fleet left an estimated $98 million in unearned potential on the table, raising the question: are storage assets being fully utilized?
