The Applicant, Electricity Provider, Inc., proposes to construct a 240 megawatt (MW) simple cycle peaking electric generating facility, consisting of four General Electric (GE) Frame 7-B water injected gas turbine engines. The Project is called the Lancaster Energy Facility #1 and will be located at the northwest corner of the intersection of Division Street and Avenue H in the City of Lancaster, California. Natural gas will be supplied to the project site via a new 22.8-mile pipeline, which will interconnect to the Mohave-Kern River pipeline and be constructed from the City of Mojave to the project site.

Overview of Power Plant and Linear Facilities

Lancaster Energy Facility #1 will be a 240 MW power plant that will utilize four natural gas-fired GE Frame-7B combustion turbine generators equipped with state of the art air pollution control features (Figure 1-3). The facility will be fired by pipeline natural gas and configured in a simple cycle mode that may eventually be converted to a combined cycle mode, if warranted. The combustion inlet air will be filtered and cooled via an inlet chiller system to increase efficiency and output. A fin fan cooler will cool the lube oil system. The generators will be air-cooled. The project will include a staging and maintenance area located on the project site.

To reduce nitrogen oxide (NOx) emissions from the project, water injection and selective catalytic reduction (SCR) technology and a carbon monoxide (CO) catalyst will be used. The SCR and CO catalyst, considered the best available control technology (BACT), are reliable and proven technologies used to reduce NOx and CO emissions. Injecting ammonia vapor (NH3) into the flue gases, which then pass through a catalyst material, further reduces the NOx emissions. The resulting chemical reaction reduces the NOx to harmless nitrogen and water.

The aqueous ammonia used to reduce emissions will be transported monthly to the site via a tanker truck, regulated by the California Department of Transportation (Caltrans). The aqueous ammonia will be stored onsite in four 25,000-gallon storage tanks, one per unit. Secondary steel containment, designed to retain a minimum of 110 percent of the storage tank volume, also will be provided. Ammonia vaporization skids will be utilized to heat the ammonia and inject it into the SCR system.

Lancaster Energy Facility #1 will be compact and consist of modular components (Figures 1-4 and 1-5). With the exception of the four 70-foot gas turbine exhaust stacks, facility components will be less than 35-feet in height and will occupy approximately four acres.

Lancaster Energy Facility #1 will be located approximately just west of an existing 66- kV Southern California Edison (SCE) circuit that ties into the SCE Lancaster Substation approximately two miles south of the project site. Connection to the system will be accomplished via a ring buss into the 66-kV circuit. Up to 200 MW could be interconnected with the Lancaster Substation without having significant adverse impacts to the system. An evaluation of the impact of adding up to 400 MW to the system is currently being conducted.

Natural gas will be supplied to the project site via a new 22.8-mile, 24-inch diameter, 700- pounds per square inch gauge (psig) gas line (Figure 1-2). (Note: The gas turbines will only require 250 to 300 psig.) The gas line will interconnect to the Mohave-Kern River pipeline and be constructed from the City of Mojave to the project site. Kern River Gas Company will provide natural gas service through this new line. The new gas line will be located in the right-of-way along the eastside of Sierra Highway until it reaches the project site at the intersection of Sierra Highway and Avenue H. The gas line will then turn 90 degrees to the east and run along the City right-of-way along Avenue H to the project site. The project will utilize approximately (maximum at 20 o F) 868,986 HHV kilo British thermal units per hour (kBtu/hr) of pipeline quality natural gas. No backup fuel supply will be used.

Lancaster Energy Facility #1 will obtain potable water from the Los Angeles County Waterworks District No. 40, Region 4 system via the City of LancasterÍs two 12-inch diameter water lines, located along Avenue H. To establish water service for the project, the City of Lancaster will extend the north line across Avenue H for about 30 feet to the property to provide service water and fire protection. The Lancaster Energy Facility #1 will consume approximately 400 gallons per minute (gpm) of water at peak use. Prior to use by the facility, potable water will be stored in a raw water tank, sent to a mobile reverse osmosis system, and finally to a demineralization system with a storage tank. The facility will discharge sanitary and process wastewaters and water from the oil/water separator system to the Los Angeles County Sanitation District 14 sewer system. To establish sewer service for the project, the City of Lancaster will extend a new sewer line about 700 feet across Avenue H onto the project site. Plant drains will be routed to a separation sump, with provisions for oil collection by an oil/water separator system. Any oil sludge will be properly disposed at an appropriate waste disposal or recycling facility.

The project will include a construction staging and maintenance area located just north of the project site. The construction staging area will be used during the construction phase of the project for parking vehicles and the storage of materials and equipment.
