AES nears permits for 844-MW Huntington Beach repowering in California

The South Coast Air Quality Management District (SCAQMD) said in a June 7 notice that it intends to approve air permit applications from AES Huntington Beach LLC for the Huntington Beach Energy Project (HBEP), which will consist of the replacement of two older utility boilers with four state-of-the-art gas turbines at Huntington Beach Generating Station in Huntington Beach.

Said the notice: “After a careful review and a detailed evaluation of the HBEP, SCAQMD has determined that the proposed project complies with all applicable federal, state and local air quality rules and regulations. Therefore, SCAQMD intends to issue Permits to Construct for the HBEP and to revise the Title V permit for this facility. However, prior to issuance of the final Title V permit, SCAQMD is providing an opportunity for public comments on the SCAQMD’s proposed decision.”

The SCAQMD is the air pollution control agency for the four-county region including all of Orange County and non-desert parts of Los Angeles, Riverside and San Bernardino counties. It will take comments on this tentative decision until July 9.

The proposed HBEP will replace the two existing electric utility boiler generator Units 1 and 2 which have been in operation since the 1950s with a new gas turbine generating system. The new system will consist of two natural gas-fired General Electric 7FA.05 combined cycle gas turbine generators configured with a steam turbine generator, and two natural gas-fired GE LMS100PB simple cycle turbine generators.

The combined generating capacity of the HBEP will be 844 MW (nominal) which replaces the generating capacity of the existing Unit 1 (215 MW) and Unit 2 (215 MW) at the Huntington Beach site as well as existing Unit 7 (460 MW) at AES Corp.’s Redondo Beach facility. The new HBEP will be equipped with air pollution control equipment, which consists of catalysts (selective catalytic reduction and oxidation catalysts). Additional new proposed equipment will include an auxiliary boiler equipped with SCR, two aqueous ammonia storage tanks and two oil water separators.

AES Huntington Beach is a unit of AES Corp. (NYSE: AES).
