Daily Energy Storage Report for 1/1/23-9/30/24 Data posted

The California ISO has posted the files with the raw data of the Daily Energy Storage Reports, covering the period from Jan. 1, 2023 through Sept. 30, 2024. Future data files will be posted on a quarterly basis.

The Daily Energy Storage Report provides selected metrics on performance of storage and hybrid resources, including system level market awards of energy and ancillary services, state of charge, and bid-in capacity for both day-ahead and real-time markets.

Given the increasing interest in this report and to improve transparency, the ISO committed to start publishing the underlying data of these reports. The new data files provide the same information in a download-able format for public access.

The data files are available on the Daily energy storage reports webpage.
