AES making progress with Huntington Beach repower project

AES Southland Development LLC said in a June 2 status report filed at the California Energy Commission for the Huntington Beach Energy Project (HBEP) that it is making progress on approvals for this project.

Commission staff docketed the Final Staff Assessment (FSA) on May 30. AES Southland, which is part of AES Corp. (NYSE: AES), is in the process of reviewing the contents of the FSA and preparing for a July 21 evidentiary hearing. The company said it will continue to meet the deadlines set forth in a commission scheduling order and looks forward to receiving a Final Decision on the project. It filed its application with the commission in June 2012.

The company said it also understands that the South Coast Air Quality Management District (SCAQMD) intended to publish the Final Determination of Compliance (FDOC) around the end of May or in early June.

The proposed HBEP would be developed by AES Southland on a 28.6-acre site located at 21730 Newland Street, just north of the intersection of the Pacific Coast Highway and Newland Street. The site is privately owned land located in an industrial area of Huntington Beach and is the currently the home of an existing plant that will be torn out when this new project is built.

The project would consist of two power blocks, each composed of three natural gas-fired combustion turbine generators with supplemental-fired heat recovery steam generators, a steam turbine generator, and air-cooled condenser. Each power block would have the ability to generate power from 110 MW to 470 MW, is designed to start and stop very quickly, and to quickly ramp up and down.

The new HBEP facility would be air-cooled, eliminating the need for large quantities of once-through cooling seawater.

The HBEP would connect the nominal 936 MW of electricity through two overhead 230-kV generation ties connecting each power block to the existing onsite Southern California Edison (SCE) Ellis switchyard. Natural gas is delivered to the current Huntington Beach Generating Station via an existing SoCalGas 16-inch diameter line to an existing gas metering station. As part of the HBEP project, a new gas metering station and new gas pressure control station would be constructed.

The HBEP would provide up to 939 MW of capacity to the western Los Angeles Basin Local Reliability Area and will replace the retiring Huntington Beach Generating Station. The HBGS is scheduled to cease operation by Dec. 31, 2020, in compliance with the California State Water Resources Control’s Board’s (SWRCB) “Water Quality Control Policy on the Use of Coastal and Estuarine Waters for Power Plant Cooling” plan, also known as the once-through cooling program.
