Project Description

The High Desert Power Project (HDPP) is located in the city of Victorville, in San Bernardino County.

The HDPP is an 830 MW gas fired, combined cycle facility, utilizing 3 Siemens 501FD2 gas turbines, 3 Alstom Heat Recovery Steam Generators (HRSG), 1 Toshiba steam turbine.

Since April 2003, the project’s primary water supply has been State Water Project (SWP) surface water purchased from the City through a contract with the Mojave Water Agency) MWA). On average, the project uses 2,700 acre-feet per year of project related water. The bulk of its industrial water is used in evaporative wet cooling towers. The project includes a zero liquid discharge system to treat and recover water from waste disposal streams.

In April 2018, the CEC approved a Post-Certification Amendment (TN 223316) to drought-proof the HDPP. HDPP will be allowed to use alternative water supplies in addition to SWP water and recycled water from the Victor Valley Water Reclamation Authority. The proposed revisions were necessary to avoid possible operational disruptions due to drought-related water reliability impacts or recycled water interruptions. New Soil and Water Resources conditions of certification create new standards for the sources and uses of water for HDPP cooling needs; make permanent the HDPP’s use of percolation for banking SWP water; and impose certain offset remedies for failing to meet or exceeding the use of recycled water.

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.
