Project Description

The El Segundo Energy Center (ESEC) facility is located at 301 Vista Del Mar Blvd., at the southernmost city limit of the city of El Segundo on the coast of the Pacific Ocean between Dockweiler State Beach and the city of Manhattan Beach. ESEC is less than 0.25 mile south of the Los Angeles Department of Water and Power’s Scattergood Generating Station, and approximately 0.5 mile south of the City of Los Angeles’ Hyperion Wastewater Treatment Plant.

ESEC is a nominal 560-megawatt (MW), natural gas-fired, combined-cycle electric generating facility. Southern California Edison previously owned and operated a power plant at this location.

A Change of Operator application was submitted to transfer ownership from SCE to NRG in 1998.

In 2000, ESEC submitted applications to the California Energy Commission (CEC) for permits to construct the El Segundo Power Redevelopment Project. As part of the proposed redevelopment project, Units 1 and 2 were to be demolished and replaced with two combined cycle gas turbines (CCGT). The CEC issued its Commission Decision in 2005 approving the El Segundo project. The El Segundo Power Redevelopment Project was not contracted by a load serving entity at that time; therefore, demolition of Units 1 and 2 and construction of the El Segundo project did not commence following the permit approvals.

In 2007, ESEC submitted a Petition to Amend the CEC Commission Decision to modify the El Segundo Power Redevelopment Project from a two-on-one (2x1) CCGT that relied on ocean cooling to two 1x1 CCGTs that incorporate fast-start capabilities and that would rely on air-cooling. The El Segundo project’s proposed capacity decreased from 647 MW to 573 MW and the gas turbines changed from General Electric 7FA to fast-start, air-cooled Siemens SGT6-5000 F. The petition was approved on June 30, 2010.

On August 13, 2008 ownership and operational control of the project was transferred from El Segundo Power Redevelopment Project to El Segundo Energy Center, LLC (ESEC).

On August 8, 2012, a petition was approved to rename the project EI Segundo Power Redevelopment Project, to the EI Segundo Energy Center project.
