CAISO Market Analysis: US Energy Insights

United States - CAISO Market

Scientifically-backed forecasts for a sustainable energy transition

California’s electricity market is operated by the California Independent System Operator (CAISO), responsible for operating the electricity system and administering wholesale electricity markets across most of the state, as well as parts of Nevada. CAISO is a leader in renewable energy integration and distributed resource management, and its wholesale market began operating in 1998.

California’s generation mix is dominated by renewable sources, especially solar and wind, in addition to hydroelectric, making CAISO one of the electricity systems with the highest renewable penetration in the world.

In the coming years, the electricity system managed by CAISO will undergo a key transformation to achieve the state’s climate goals:

State legislation requires that 100% of electricity comes from clean sources by 2045, which implies a massive deployment of renewable energy, storage, and electrification.
CAISO leads the development of regional markets, such as the Energy Imbalance Market (EIM), which allows neighboring states to exchange energy in real time, and is working on the creation of the Extended Day-Ahead Market (EDAM).
The system faces challenges related to flexibility, managing demand peaks, and resilience to wildfires and extreme weather events.
Solutions are being advanced, such as large-scale storage, demand response, bidirectional electric vehicles, and distributed energy resource (DER) management.
