Los Esteros Critical Energy Facility

The Los Esteros Critical Energy Facility (LECEF), located in San Jose, Calif., was constructed and placed in operation by Calpine in 2003 pursuant to a power purchase agreement with the California Department of Water Resources.

In 2009, Calpine announced an agreement with Pacific Gas & Electric that resulted in upgrading LECEF from a simple-cycle generation facility to a combined-cycle generation facility capable of generating up to 309 megawatts of electricity. In addition to the increase in capacity, the upgrade project increased the efficiency and environmental performance of the plant by significantly lowering its heat rate. The upgrade was completed in August 2013.
