California commission to hold Feb. 17 workshop on 699-MW Palmdale project

The California Energy Commission staff will conduct on Feb. 17 Data Response and Issues Resolution Workshop No. 2 for a Petition to Amend (PTA) the commission’s prior decision to approve a certificate for the Palmdale Energy Project (PEP).

The purpose of the workshop is to allow staff and the project applicant to discuss data responses regarding the PEP, said a Feb. 1 meeting notice. Staff and the applicant will be prepared to discuss all remaining technical areas as necessary. An opportunity will also be provided for public comment.

Staff is seeking clarification on data responses filed for several technical issues, including those related to: Air Quality and Greenhouse Gasses; Cultural Resources; Public Health; Soil & Water Resources; and Transmission System Engineering.

On April 30, 2015, the project owner, Palmdale Energy LLC filed the amendment petition with the commission. The owner submitted a revised comprehensive PTA on July 17, 2015, requesting that the name of the project be changed from the Palmdale Hybrid Power Project to the PEP, and also to modify the technology of the facility. The PEP will be located on approximately 50 acres of land in the city of Palmdale, located in Los Angeles County, California.

The PTA requests primary modifications to the PEP to:

  • eliminate the solar component of the proposed project;
  • incorporate newer, fast start, flexible natural gas turbine technology; and
  • to replace the water cooling tower with an air-cooled condenser.

The proposed PEP would have a nominal capacity of 645 MW. Primary equipment for the facility would include two natural gas-fired combustion turbine-generators rated at 220 MW each, two heat recovery steam generators (HRSGs), one steam turbine-generator rated at 232 MW, and one auxiliary boiler. The plant would have an overall gross output of about 699.4 MW (net) with HRSG duct burners in-service.

The Palmdale Hybrid Power Project was originally licensed as a nominal 570-MW hybrid facility utilizing combined-cycle gas and solar trough technologies located in the city of Palmdale. The facility, originally to be built by the city of Palmdale, was not constructed. In April of last year, Palmdale Energy LLC, a solely owned subsidiary of Summit Power Project Holdings LLC, filed for this amendment, saying it had taken over the project from the city.
