California commission may decide on Alamitos repower project in December

The California Energy Commission staff filed an Aug. 15 scheduling memo in the Alamitos Energy Center review docket that suggests a Dec. 14 final decision on the application.

The staff’s Preliminary Staff Assessment (PSA) was filed to the docket on July 13. A PSA workshop was held Aug. 9 in Long Beach. The PSA comment period closed Aug. 12. Engineering and Environmental technical staff are addressing applicant and public comments as they prepare final FSA sections. Air quality staff members are working with the South Coast Air Quality Management District (SCAQMD).

Staff proposes a Final Staff Assessment (FSA) schedule that includes:

  • Application for Certification filed, 12/27/13
  • Supplemental Application for Certification (SAFC) filed, 10/26/15
  • SCAQMD issues Preliminary Determination of Compliance (PDOC), 7/1/16
  • SCAQMD PDOC comment period closes, 8/22/16
  • SCAQMD issues Final Determination of Compliance (FDOC), to be determined
  • Final Staff Assessment filed, FDOC + 30 days
  • Prehearing Conference (If necessary), to be determined
  • Evidentiary hearings, to be determined
  • Commission committee files Presiding Member’s Proposed Decision (PMPD), to be determined
  • Hearings on the PMPD, to be determined
  • Committee files errata or revised PMPD (if necessary), to be determined
  • Commission issues Final Decision, 12/14/16

In December 2013, AES Southland Development LLC (AES-SD) submitted an Application for Certification (AFC) to modernize the existing Alamitos Generating Station (AGS). The original AFC proposed a natural gas-fired, fast starting, combined-cycle gas turbine, air-cooled facility with a net generating capacity of 1,936 MW, to replace, and be constructed on the AGS site. It is called the Alamitos Energy Center (AEC), and would be located in the city of Long Beach, Los Angeles County.

In October 2015, AES-SD submitted the SAFC to address significant revisions to the design for modernizing the existing AGS. The SAFC replaces the original AFC. The revised AEC would include a nominal 640-MW, natural gas-fired, combined-cycle power block and a 400-MW simple-cycle, air-cooled facility. Power Block 1 would consist of two natural gas-fired combustion turbine generators (CTG) in a combined-cycle configuration with two unfired heat recovery steam generators (HRSG), one steam turbine generator (STG), an air cooled condenser, an auxiliary boiler, and related ancillary equipment. Power Block 2 would consist of four simple-cycle CTGs with fin-fan coolers and ancillary facilities.
