California agency plans workshop on second El Segundo repowering

California Energy Commission staff will hold an Oct. 1 workshop on the proposed El Segundo Energy Center Amendment, which would add further repowered capacity at NRG Energy’s (NYSE: NRG) gas-fired El Segundo power plant.

The workshop will be at the commission’s offices in Sacramento. it is being held to allow staff, the applicant, interested agencies, intervenors, and the public to ask for clarification about staff’s data requests and discuss the applicant’s responses. The workshop will also work to resolve project issues and the project schedule.

The topics to be discussed include: air quality; alternatives; biological resources; cultural resources; project description; socioeconomics; soil and water resources; visual resources; and waste management. Other technical areas may be discussed. The public will be able to comment and ask questions about the proposed project.

The applicant for the amendment is El Segundo Energy Center LLC, a subsidiary of NRG Energy. The project site is located at 301 Vista Del Mar Boulevard in El Segundo in Los Angeles County.

El Segundo is a 1,052-MW natural gas-fired plant built in the 1950s. In 2005, the commission approved a plan to demolish and replace Units 1 and 2 with Units 5, 6, and 7 with the continued use of once-through cooling. In 2010, the commission approved an amendment to install four rapid start combined-cycle units (Units 5-8) using dry cooling technology. Commercial operation of Units 5-8 began in August of this year.

In April of this year, the company filed an amendment that would demolish two steam boiler units (Units 3 and 4) and replace them with 449 MW of dry-cooled, natural gas-fired capacity (Units 9-12). This amendment is expected to eliminate the use of ocean water for once-through cooling. When completed, the facility’s total capacity would be 1,022 MW (Units 5-12).

If the commission approves the latest El Segundo amendment, the applicant plans to demolish Units 3 and 4 by the end of 2015. Construction is expected to start by mid-2016 and conclude in 2018. The estimated capital cost is $420m to $500m.
