Does caiso own energy storage assets

Does CAISO operate a capacity market?

Unlike other ISOs and RTOs such as PJM, CAISO does not operate a capacity market. However, it does facilitate the Western Energy Imbalance Market (WEIM), the only real-time energy-only market in the U.S.

How many MW does CAISO have in 2024?

Entering this year, CAISO-connected nonhydro energy storage totaled 8,453 MW, almost all of which was built over the last four years. Batteries make up the largest share of the planned 12,126 MW of net CAISO capacity additions in 2024, followed by 4,801 MW of anticipated new solar capacity, which is frequently coupled with storage, the data shows.

Why are CAISO power plants still online?

But retirements have been delayed. Instead, at the urging of Gov. Gavin Newsom, CAISO President and CEO Elliot Mainzer, state lawmakers and energy regulators, those plants will remain online for at least the next few years due to grid reliability concerns.

Will CAISO reform its generator interconnection process in 2024?

The robust year of resource development in 2024 comes as CAISO works to complete a major initiative to reform its generator interconnection process to ensure a smoother pathway for future energy and storage projects. The grid operator issued a final reform proposal March 29 that could go before CAISO's board in May.

How many GW is CAISO generating a year?

Every one of the top ten instantaneous solar generation records in CAISO occurred in the final 3 weeks of April (before we hit May, which has already nabbed three of the spots). Before this streak, the peak output was barely over 16 GW in September of 2023. Now the record stands at more than 18.5 GW and is poised to keep growing.

What does CAISO do?

It offers both a day-ahead and real-time energy market. As the market coordinator, CAISO is responsible for balancing the needs and equitable access of all market participants, as well as ensuring the reliability of the grid at the lowest cost possible. CAISO also operates an ancillary services market to maintain grid stability and reliability.
