California commission plans June 28 site visit for 300-MW Mission Rock project

The California Energy Commission has scheduled a June 28 site visit and informational hearing so interested parties can get more details on the Mission Rock Energy Center project. 

On Dec. 30, 2015, Mission Rock Energy LLC filed with the commission an Aplication for Certification (AFC) for this project. On May 17, the commission accepted the AFC as “data adequate.”

To be located in Ventura County, the Mission Rock Energy Center will be a natural gas-fired, simple-cycle combustion turbine facility rated at a nominal generating capacity of 275 MW, co-located with battery units for the storage of electricity that can deliver an additional 25 MW.

Mission Rock Energy Center LLC is a unit of Calpine Corp. (NYSE: CPN).

Mission Rock filed this AFC under the California Energy Commission’s 12-month licensing process. Construction of the MREC is expected to begin in November 2018, said the AFC filed last December. Pre-operational testing of the power plant is expected to begin in April 2020, and full-scale commercial operation is expected to begin by September 2020.

The MREC’s primary objective is to combine dispatchable, operationally flexible, and efficient generation with state-of-the-art storage technology, to meet the need for new local capacity in the Moorpark Subarea of the Big Creek/Ventura local reliability area of Southern California Edison’s (SCE’s) service territory. The same energy storage system that provides MREC with black start capability will also provide an additional 25 MW/100 MW hours of flexible, preferred resource capacity to the grid.

The energy storage system will be used to store energy during times of over-generation, which may be caused by intermittent renewable generation, and delivered back to the grid when needed. Operationally flexible resources are increasingly needed to assist with the integration of intermittent renewable resources, such as solar and wind facilities, for grid operation. Additionally, peaking capacity is needed to respond to increases in the local demand for electricity that typically occur in the afternoons of summer days. The MREC is expected to run intermittently and provide real-time energy and voltage support to the grid.

The MREC site is located in unincorporated Ventura County, west of the City of Santa Paula, at 1025 Mission Rock Road. The MREC site is a 9.79-acre parcel currently used for recreational vehicle and boat storage which is almost entirely paved with asphalt-concrete.

MREC will interconnect to the SCE Santa Clara Substation via a new 6.6-mile, 230-kV transmission line located approximately 4.5 miles west of the MREC site. The natural gas line interconnection for the power plant entails constructing approximately 2.4 miles of new 16-inch pipeline directly southwest from the project site to the point of interconnection with the Southern California Gas high-pressure natural gas transmission lines 404/406.
