CPUC Approves NRG Energy's 500-MW Carlsbad Energy Center

LCG, May 28, 2015-The California Public Utilities Commission (CPUC) approved late last week the SDG&E Power Purchase and Tolling Agreement for the NRG Energy, Inc. Carlsbad Energy Center, a proposed 500-MW, natural gas-fired peaking facility. The project is expected to begin operations when the adjacent Encina Power Station is retired at the end of 2017.

The Carlsbad Energy Center will include five units to increase reliability in southern California given the closure of the San Onofre Nuclear Generating Station (SONGS) in 2013 and the planned retirement of the Encina Generating Station due to California's Once-Through-Cooling ban. The proposed electric generating facility will be located in the City of Carlsbad in San Diego County.

The president of NRG Energy's West region stated, "We appreciate the CPUC's vote of confidence that the Carlsbad Energy Center is the best approach to have the appropriate, flexible capacity online by 2017 to enable California to reach its greenhouse gas reduction goals through building additional renewable generation while preserving the reliability of the grid. We appreciate the CAISO's recognition of the project's contribution to the grid and SDG&E's continued support of the project and the benefits it will bring to all of southern California. And we appreciate the City of Carlsbad's focus on the environmental benefits of the project to build a smaller, more efficient plant that complies with the State's once-through-cooling policies, and enables the demolition of Encina and development of the underlying coastline property."

The original application for certification was filed with the California Energy Commission (CEC) in September 2007.
