| Applicant: | Calpine Corporation |
| General Description: | The electric power project, proposed by Calpine Corporation, is a 540 megawatt (MW), natural gas-fired, combined cycle facility. |
| Project Location: | The Sutter Power Project will be located adjacent to Calpine's Greenleaf Unit 1, a gas-fired, cogeneration power plant located approximately seven miles southwest of Yuba City on South Township Road at its intersection with Best Road. The land dedicated for the facility will comprise 10-12 acres of Calpine's existing 77-acre parcel (Sutter County Assessor's Parcel Number 21-230-25). The legal description of the 77 acres is: the north half of the northeast quarter of Section 24, Township 14 North, Range 2 East, Sutter County. {We Will Eventually Link To Project Maps} |
| Project Cost: | Calpine estimates the capital cost of the Sutter Power Project at approximately $250-285 million. The project will contribute to the local economy by employing about 256 workers during peak construction and about 20 permanent jobs during plant operations. |
| Permitting Process: | The California Energy Commission is responsible for
permitting the proposed Sutter Power Project. The Energy Commission
will carefully examine public health and safety, environmental impacts
and engineering aspects of the proposed power project including all
related facilities such as electric transmission lines, natural gas pile
lines, etc. The Energy Commission responsibilities are similar to those
of a lead agency under the California Environmental Quality Act
(CEQA). The permitting process is open to the public and includes input from the public and all interested parties as well as working in consultation with other local, state and federal agencies. Because the project will interconnect with the Western Area Powr Administration's high voltage transmission line, the review will be completed jointly with WAPA, the federal lead agency for this project. Since the project site is currently zoned for agricultural uses, Calpine will request Sutter County to permit a rezone of the 77-acre parcel to a Planned Development site thus allowing this industrial use. Sutter County and the Energy Commission reviews will occur concurrently to ensure no delay in the review processes. {We will soon link to the project calendar.} |
| Construction Schedule: | Calpine anticipates starting construction in 1999. |
| Operation Schedule: | Calpine anticipates beginning commercial operation by the end of 2000. |
| Electricity Sales: | Electrical energy produced from the proposed power plant will be sold in California's newly created electricity market. |
| Facility Operation: | Calpine expects the project to have an overall availability
of between 90 and 95% and could operate up to 8,322 hours per year.
Since the project will be selling electricity into the emerging
California market, the plant will be designed to provide electricity
during peak load periods as well as operate as an intermediate or
baseload facility. The project will be capable of 300 start-ups and
shut-downs during the year as it responds to the market.
|
| Project Design: | The combined cycle design consists of two combustion turbine generators (CTGs), two heat recovery steam generators (HRSGs) with duct burners and a steam turbine generator (STG). Each CTG will produce approximately 170 MW of electricity. The CTG's exhaust gases will be used to generate steam in the HRSGs. The HRSGs will be reheat design with duct firing. Steam from the HRSGs will be admitted to a condensing steam turbine for an additional 160 MWs of electrical power generation. |
| Electric Transmission Line: | A new 4.0 mile 230 kilovolt (kV) overhead electric transmission line will be built to a switching station which will interconnect to the Western Area Power Administration electrical transmission system. The line will be configured to minimize electromagnetic fields (EMF). |
| Natural Gas Fuel Line: | A new 12 mile natural gas pipeline will be constructed to provide fuel for the project. The 16 inch gas pipeline will connect to an existing PG&E natural gas supply line located to the west of the facility site. PG&E will construct the gas supply line. |
| Emission Controls: | Nitrogen oxide (NOx) emissions from the combustion process will be reduced to 25 parts per million by volume dry (ppmvd), at 15 percent oxygen by utilizing dry low NOx combustion technology. The HRSGs will incorporate an 84% effective selective catalytic reduction (SCR) system to control NOx emissions to 4 ppmvd at 15% oxygen. The SCR will use anhydrous ammonia and a precious metal catalyst to convert NOx molecules into nitrogen and water. Each HRSG's exhaust to the atmosphere will be through 18-foot diameter, 185-foot tall exhaust stacks. |
| Water Supply: | Potable water and cooling water will be provided by an on
site well system that will be developed as part of the project. It is
expected that three wells will be developed to
provide approximately 3,000 gallons per minute of water that will be
needed during peak operating conditions.
|
| Waste Water: | Sanitary waste will be disposed to an on-site septic system.
All other wastewater generated in the operation of the plant will be
discharged to the existing surface drainage system requiring a National
Pollutant Discharge Elimination System (NPDES) Permit.
