Department of Market Monitoring 2023 Annual Report on Market Issues and Performance, call on 8/7/24

The California ISO Department of Market Monitoring has posted the 2023 Annual Report on Market Issues and Performance, and has scheduled a stakeholder call on Aug. 7, 2024, to discuss reported analysis and findings.

The 2023 Annual Report provides highlights of significant market changes and performance. In the California ISO market, total wholesale electric costs decreased by around 32 percent to about $14.5 billion, or about $65/MWh, due to substantially lower natural gas prices. Total battery capacity participating in the CAISO balancing area has increased significantly since 2016, and totaled about 11,100 MW of discharge capacity by June 2024.

Expansion of the Western Energy Imbalance Market helped improve the overall structure of the real-time market in the CAISO and other participating balancing areas. In 2023, three new balancing areas joined the market.

Net imports into the California ISO continued to fall significantly, as exports increased. Summer supply margins were bolstered by the integration of additional capacity. The report finds that the ISO and energy imbalance markets continued to perform efficiently and competitively.

Information related to market monitoring is available on the Market Monitoring webpage.
