Project Description |
On September 13, 2001, SMUD filed an Application for Certification (AFC) seeking approval from the Energy Commission to construct and operate a power plant approximately 1,000 feet south of the Rancho Seco Nuclear Plant, 25 miles southeast of the City of Sacramento, in Sacramento County. The project would be located on approximately 30-acres of an overall 2,480-acre site owned by SMUD.
The proposed CPP will consist of a nominal 1000 MW combined cycle natural gas facility. The plant will be constructed in two phases, each consisting of 500 MW. Each phase will have two combustion turbines, one condensing steam turbine, and two heat recovery steam generators (HRSG).

|
Transmission Line |
Approximately 0.4 miles of new 230-kV line from the on-site switchyard to the existing switchyard at the Rancho Seco nuclear power plant facility will be constructed. |
|
Natural Gas |
Natural gas will be supplied to the project by extending a natural pipeline 26 miles originating from the Carson Ice-Gen Facility, in Sacramento County. |
|
Water Supply |
In a typical year, the CPP would require 8,000 acre-feet of water. Water will be provided to the project site by a 12-inch water line extending from the Rancho Seco Nuclear Plant. Water to the Rancho Seco nuclear plant originates from the American River and conveyed via the Folsom-South Canal. A package treatment plant will provide domestic water. |
|
Waste Water |
Sanitary wastewater will be collected and discharged to a package sanitary waste treatment system and leach field. Wastewater containing cleaning chemicals will be trucked off-site for disposal. Spent plant cooling water will be treated and discharged to Clay Creek. |
|
Capital Costs |
The project costs are expected to be $595 million. |
|
Project Schedule |
Construction for both phases will occur between
fourth quarter 2002 to fourth quarter 2007.
Commercial operation of Phase I will begin
the first quarter of 2005. Commercial operation
of Phase II will begin first quarter 2008.
