Electricity Market Data

The University of California Energy Institute (UCEI) sponsored a collection of data related to the restructured electricity markets in California.  All of the data contained on this page were publicly available.  Some data series were reformatted from their original release so as to be more accessible.  Data collection efforts were discontinued as of July 2003.
