East Altamonst Energy Center
Fact Sheet
01-AFC-4

The project site (55 fenced acres) will be located in a rural portion of Alameda County while gas and water lines cross into San Joaquin and Contra Costa counties. The landmarks are: Mountain House (newly approved town) 1 mile southeast; Clifton Court Forebay 2 miles north; Bethany Reservoir 5 miles southwest; Livermore 12 miles west and Byron 5 miles north. The EAEC will be located between Byron Bethany Road and Kelso Road with Mountain House Road to the west.
On March 29, 2001, Calpine Corporation submitted an Application for Certification (AFC) to the California Energy Commission seeking approval to construct a nominal 1,100-megawatt (MW), natural-gas-fired combined-cycle generating facility. The Commission's responsibilities are similar to those of a lead agency under the California Environmental Quality Act (CEQA). The Energy Commission's facility certification process will carefully examine public health and safety, environmental impacts and engineering aspects of the proposed power plant and all related facilities such as electric transmission lines, natural gas and water pipelines, and roads.
FACTS ABOUT THE PROPOSED EAST ALTAMONT ENERGY CENTER
  • If built, the 55 acre fenced site will include: generation equipment, water treatment, evaporation ponds, wastewater pond, storm water retention pond, switchyard, emission control equipment, storage tank, parking and administration building. Generating facilities will include: three combustion turbine generators, three heat recovery steam generators (stacks 175' tall by 20') with duct burners, a condensing steam turbine generator, 19-cell mechanical draft cooling tower, a 100' by 4' auxiliary boiler stack and a 90' brine concentrator.
  • EAEC needs 4,600 acre-feet of water in a typical year. Cooling and process water will be supplied by the Byron Bethany Irrigation District; using 2.1 miles of new water supply lines constructed to convey surface water district. In the future, as it becomes available, recycled wastewater will be utilized from Mountain House Community Service District Wastewater Treatment Plant via 4.6 miles of new water supply line.
  • New 230-kilovolt (kV) transmission lines approximately 0.5 miles long will join existing 230-kV lines which already connect to the Tracy substation owned by Western Area Power Administration (Western).
  • Natural gas will be delivered to EAEC via 1.8 miles of new gas line from the PG & E pipeline tap point.
  • EAEC's site, under purchase option, occupies 55 acres of a 174-acre parcel marked for agricultural usage.
