Summary

This livestream from Modo Energy provides an in-depth analysis of the battery energy storage system (BESS) market in the California Independent System Operator (CAISO) region as of October 2025. The presentation covers the current state of installed capacity, deployment trends, and future projections. It highlights that CAISO has approximately 15 GW of operational front-of-the-meter batteries, with a significant portion being four-hour duration assets. The discussion includes the geographic distribution of storage, with a concentration in Southern California, and the growing trend of standalone storage. The interconnection queue is analyzed, with expectations of reaching 24 GW by 2028 and 44 GW by 2035, after accounting for transmission deliverability constraints. The revenue landscape is examined, showing a decline in merchant revenues due to reduced price volatility, while resource adequacy (RA) contracts now constitute a larger share of revenue. The presentation also touches on upcoming policy changes, such as slice-of-day RA requirements and Western Energy Imbalance Market integration. The overall tone is informative, aimed at industry professionals, and provides valuable insights into the BESS market dynamics in CAISO.
