Overview of Power Plant and Linear Facilities
The Baldwin Energy Facility No. 1 (Baldwin No. 1) will consist of two natural gas-fueled GE- LM-2500 generation sets, nominally rated at 26.5 megawatts (MW) each. The GE- LM-2500 turbines are aero-derivative gas turbines used in the DC-10 jet engine, aswell as throughout the world for electrical generation. The facility will be configured in asimple cycle mode.
The turbines will initially be water-injected to reduce the nitrogen oxide (NOX) emissions to 25 ppm. The final configuration will include the installation of steam injection utilizing heat recovery steam generators (HRSG), Selective Catalytic Reduction (SCR) system and an oxidation catalyst to be manufactured and installed in late 2001 or early 2002. SCR is considered a best available control technology (BACT) and is a reliable and proven means of reducing NOX emissions. The NOX emissions will be reduced to 5 ppm once the SCR system is installed.
The SCR system uses aqueous ammonia to convert the NOX to harmless nitrogen and water. Aqueous ammonia will be transported to the site in California Department ofTransportation (DOT) regulated vehicles and stored onsite in a 5000 gallon steel storage tank installed with secondary containment.
Baldwin No. 1 will burn pipeline-quality natural gas, supplied through a new 6" interconnection to an existing Southern California Gas Company (SoCalGas) 12", 500 psig line within the Inglewood Oilfield. The project will use approximately 10,000 MCF per day (430 MMBtu/hr) of natural gas.
The electrical connection will be made to existing 69 kilovolt overhead lines that run on the east side of La Cienega Boulevard. New overhead lines will be run to connect the existing lines on La Cienega to the plant's switchyard.
The plant will use a maximum of 340 gpm of fresh water. It will be supplied from theexisting freshwater/firewater system within the Inglewood Oilfield. The Oilfield's water lines are connected to the California-American Water Company's 6" main line that serves the water tank reservoir within the Inglewood Oilfield. The fresh water will be treated using a demineralization process to make it suitable for water and steam injection into the turbine. A waste stream of 100 gpm (3,429 BWPD) from the demineralization unit will consist of the hard water components of fresh water. This waste stream and wastewater products form the generating process will be blended with the 215,000 BWPD of brackish water produced from the Inglewood Oilfield and re-injected into the Oilfield reservoir as part of the Oilfield's waterflood process.
