California Electricity Market Data

---

The University of California Energy Institute (UCEI) sponsored a collection of data related to the newly restructured electricity markets in California.  All of the data contained on this page are publicly available.  Some data series have been reformatted from their original release so as to be more accessible.  Although we have made every effort to ensure accurate conversion, we make no claims or guarantees as to the accuracy of the data.  A description of our data formats can be found here. Data collection efforts were discontinued as of July 2003.
