California commission to hold July 12 workshop on Huntington repowering

The California Energy Commission staff will conduct a July 12 public workshop for the amended Huntington Beach Energy Project, which is being pursued by a subsidiary of AES Corp. (NYSE: AES).

All interested parties, agencies and members of the public are invited to participate in the workshop, which will be held at the Huntington Beach Public Library. The workshop will allow commission staff, Huntington Beach Energy LLC officals, interested agencies and the public to discuss the Preliminary Staff Assessment (PSA) for the Huntington Beach Energy Project – Petition to Amend (HBEP-PTA).

The PSA contains the Energy Commission staff’s independent, objective evaluation of the proposed amended HBEP project. The PSA was published on June 24.

In June 2012, AES Southland LLC submitted an Application for Certification (AFC) for the HBEP. In October 2014, the Energy Commission issued a final decision approving a license for the construction and operation of the HBEP facility. In September 2015, AES Southland submitted a Petition to Amend (PTA) the decision.

The requested amendment is the result of the selection by Southern California Edison (SCE) of the revised AES project in the 2013 Local Capacity Requirements tequest for offers to provide 644 MW of nominal capacity, with different technology than that originally permitted in the HBEP Final Decision. The PTA proposes to modify the previously approved 939-MW plant to a new configuration that would total 844 MW.

Construction would commence in two phases with the first phase consisting of a natural gas-fired, combined-cycle, air-cooled, 644-MW facility. After the first phase combined-cycle power block is operational, phase two would begin with adding two 100-MW simple-cycle gas turbines (SCGT).

If the Amended HBEP is approved by the Energy Commission, construction and demolition activities at the project site are anticipated to take approximately 10 years, lasting through the fourth quarter of 2025. The PTA indicates a construction schedule for the various phases of activities with the combined-cycle, gas turbine (CCGT) phase 1, power block 1, anticipated to begin in the second quarter of 2017 with commercial operation of power block 1 during the second quarter of 2020. Existing units 3 and 4 would then be demolished.

Construction of the SCGT phase 2, power block 2, is anticipated to begin during the first quarter of 2022 with commercial operation during the first quarter of 2024. Existing units 1 and 2 would then be demolished.
