The Northern California Power Agency’s (NCPA) Lodi Energy Center (LEC) is located at 12745 Thornton Rd on land owned and incorporated by the city of Lodi, San Joaquin County.
LEC is a nominal 296-megawatt (MW), natural gas-fired, combined-cycle facility consisting of one natural gas-fired combustion turbine generator, one condensing steam turbine generator, a heat recovery steam generator, a condensing steam turbine generator, a natural gas-fired auxiliary boiler and a cooling tower.
LEC is adjacent to the City of Lodi's White Slough Water Pollution Control Facility (WPCF) to the east, treatment and holding ponds associated with the WPCF to the north, the existing 49 MW NCPA Combustion Turbine Project #2 (STIG Plant 2) to the west, and the San Joaquin County Mosquito and Vector Control facility to the south.
On August 20, 2014, the California Energy Commission (CEC) approved a Post-Certification Amendment (TN 202964) to address a wastewater discharge permitting issue associated with the wastewater underground injection wells and discharge process. The CEC approved LEC’s backup method of process wastewater disposal (a cross-connect to the STIG wastewater tank and subsequent Wastewater Discharge Permit issued by the City) and the LEC injection well(s) can function as temporary backup for STIG wastewater disposal.

Power Plant Certification and Exemption Processes
The CEC has the exclusive authority to certify all thermal power plants 50 megawatts (MW) and larger and related facilities proposed for construction in California. The Application for Certification (AFC) process is a certified regulatory program under the California Environmental Quality Act (CEQA). As a certified regulatory program, the CEC does not prepare environmental impact reports (EIRs) in an AFC proceeding, but instead prepares environmental assessment documents that are functionally equivalent to EIRs. A certificate issued by the CEC is in lieu of any permit, certificate, or similar document otherwise required by any state, local or regional agency, or federal agency to the extent permitted by federal law, and supersedes any applicable statute, ordinance, or regulation of any state, local, or regional agency, or federal agency to the extent permitted by federal law.
