City of Vernon (Malburg Generation Station) Combined Cycle Power Plant Project Description

Docket Number:

(Application For Certification)


Project Title:

City of Vernon, Malburg Generating Station Combined Cycle Project (MGS)


City of Vernon
Project Contact: Ramon Abueg, P.E.
Phone: (323) 583-8811


The existing Station A site located at 2715 East 50th Street, in Vernon, California.


The total Project cost is estimated to be approximately $100 to $110 million.


The MGS will be constructed, owned, and operated by the City of Vernon, and would become an asset of its Utilities Department for the City’s electric system.


The MGS is planned to begin commercial operation during the fourth quarter of 2003 after about a 16-month construction and initial commissioning period.

Commercial Operation:

The City of Vernon purchases and sells energy from and to third parties via the Western Systems Power Pool and Cal-ISO.


The proposed MGS would be constructed and operated to sell its output to customers of the City of Vernon and to other customers in Southern California.


Natural gas-fired, combined cycle power plant.


The Project would consist of two ALSTOM GTX100 frame-type natural gas combustion turbine-generators (CTGs) with dry low-NOx (DLN) combustors for oxides of nitrogen (NOx) control. The CTGs would each be equipped with evaporative inlet air coolers/filters to enhance turbine performance in hot weather.

Transmission Line:

The new generation would be connected to the existing 69 kV bus in the Vernon Substation on the MGS site.


Natural gas would be the only fuel utilized by the new facility. Natural gas would be supplied via a Southern California Gas Company (SoCalGas) pipeline. A new eight-inch diameter natural gas pipeline will be constructed, running 1,100 feet north under Serville Avenue to connect with an existing pipeline under Fruitland Avenue. An additional 200 feet of new underground pipeline would be installed on the project site.


The Project would use reclaimed water for the cooling tower make up, purchased by the City and supplied by the Central Basin Municipal Water District (CBMWD). Potable water would only be utilized for domestic and sanitary use.

A new 18-inch diameter, 10,000-foot long reclaimed water pipeline would be constructed to deliver reclaimed water to the MGS site from the existing CBMWD reclaimed water supply system.

Air Quality
Emission Controls:

The regulated air pollutant emissions of the MGS would be offset by purchasing the emission reduction credits (ERCs) for CO, suspended particulate matter of diameter less than 10 microns (PM10), and VOCs; and reclaim trading credits (RTCs) for NOx from either or both the South Coast Air Quality Management District (SCAQMD) or the open market.

In addition, the Project would incorporate the following state-of-the-art air pollution controls that reflect Best Available Control Technologies (BACT) to reduce emissions:

  • DLN burner technology and SCR to reduce NOx emissions to 2 parts per million (ppm) (1-hour rolling average) @ 15 percent oxygen (O2) dry.
  • An oxidation catalyst to limit CO emissions to 2 ppm (3-hour rolling average) @ 15 percent O2 dry and VOC emissions to 1.2 ppm (1-hour rolling average) @ 15 percent O2 dry.
  • Pipeline-quality natural gas as fuel to limit SO2 and PM10 emissions.


A 1,300-foot long 12-inch sewer line from the Project to Fruitland Avenue would be required for discharge to the local sewer. From that point on the existing sewer trunk is capable of handling all wastewater flows from the Project. The wastewater would flow through the County Sanitation District of Los Angles County (CSDLAC) existing treatment facility. No improvements to the treatment facility are required.
