Woodland Generating Station 2 PROJECT FACT SHEET

Applicant

Modesto Irrigation District

General Description

Woodland Generation Station 2 is a proposed nominal 80-megawatt, natural gas-fired, combined cycle power plant.

For a list of documents for the Woodland Generation Station 2, please go to the California Energy Commission's web page at

http://www.energy.ca.gov/sitingcases/modesto/

Project Location

The proposed site for the Woodland Generation Station 2 is 920 Woodland Avenue in Modesto, California, in Stanislaus County. The power plant will occupy a 2.5-acre portion of a seven-acre site where an existing generating facility, Woodland 1, is already located. The site is bordered by the existing Woodland 1 facility, 9th Street and the Union Pacific Railroad tracks to the east, MID’s service facility to the north (across Woodland Avenue), Graphics Drive to the west, and the vacant FMC Corporation site to the south.

Project Cost and Employment

Modesto Irrigation District estimates the capital costs of the Woodland Generating Station 2 to be $60 million. The applicant expects to employ an average construction workforce of 72 workers and a peak construction workforce of 97 workers in the 8th and 9th months of construction. There will also be a workforce of 71 workers during peak construction for the gas line reinforcements. In addition to the current workforce for the existing Woodland 1 facility, 3 to 4 additional permanent employees are anticipated for plant operation. Construction payroll costs are estimated to be $8.9 million while annual operations payroll is expected to be $280,000 for the additional four plant workers.

Permitting Process

The California Energy Commission is the lead agency responsible for permitting the proposed 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 (transmission lines, water lines, natural gas pipelines, and other ancillary structures). The Energy Commission's responsibilities are similar to those of a lead agency under the California Environmental Quality Act.

The permitting process is open to the public and includes numerous opportunities for the public and other interested parties to provide input. The Energy Commission will be working in close consultation with local, state and federal agencies to coordinate analysis of the potential impacts of the project.

The Energy Commission's review of the project was initiated on May 4, 2001 when Modesto Irrigation District submitted its Application for Small Power Plant Exemption. On May 25, Modesto Irrigation District filed a document entitled Gas Supply Line Modifications, Modesto Irrigation District Project (01-SPPE-01). The Issue Identification Report was released on June 18, 2001.

Construction Schedule

If approved by the Energy Commission, Modesto Irrigation District expects to begin construction of the project by the Winter of 2001 and complete it by the Spring of 2003.

Operation Schedule

The applicant anticipates beginning plant testing in the second quarter of 2003 and full-scale commercial operation is expected to commence in the Summer of 2003.

Electricity Sales

Electrical energy produced by the proposed facility will be to serve residential, industrial, and commercial customers in and around the City of Modesto and in neighboring areas in Stanislaus and San Joaquin Counties.

Project Design

The proposed power plant will use either a convention drum-type heart recovery steam generator (HRSG) or a once-through steam generator (OTSG) HRSG. The plant will use a single GE LM6000 enhanced SPRINT combustion turbine generator (CTG) and a single condensing steam turbine generator (STG). The CTG will only fire natural gas.

Electric Transmission Line

Approximately 1.2 miles of 69-kV subtransmission line improvements will be required starting from the existing facility and ending at Modesto Irrigation Districts’s Enslen Substation, about one mile southeast. The transmission line improvements will follow an existing transmission line route that currently connects Woodland 1 with the substation.

Natural Gas Fuel Line

Pacific Gas and Electric Co. (PG&E) will deliver the natural gas required for the proposed power plant through the existing gas line connection to the Woodland 1 plant. However, due to the increased capacity needed to serve WSG2 plant, two new segments of gas pipelines will need to be constructed in San Joaquin County. The new gas pipeline segments include approximately 3.25 miles of 12-inch diameter reinforcement to PG&E’s Ripon-Modesto Distribution Feeder Main (DFM) that will be located west and south of downtown Ripon, and 3 miles of pipeline adjacent to PG&E’s Line 108 in agricultural areas west of Ripon.

Emission Controls

The WGS2 project will be equipped with Best Available Control Technology (BACT) to control air pollutant emissions. These controls include a water injection system to reduce the NOx emissions from the CTG exhaust and a NOx selective catalytic reduction system (SCR) to reduce emissioms to 2.5 parts per million (ppm) at full load. In addition, there will be a continuous emission monitoring system for the exhaust stack. The SCR system uses aqueous ammonia as a reagent for an ammonia injection system and an oxidation catalyst to maintain CO emission limit of 6.0 ppm in all operating conditions.

Water Supply and Discharge

The average daily water demand water demand for the Woodland Generating Station 2 is approximately 290 gallons per minute (gpm) and the approximate maximum daily water demand is 705 gpm. Woodland Generating Station 2 will use water transported from Modesto Regional Water Treatment Plant at Modesto Irrigation District’s Reservoir for cooling process make-up and domestic water uses. A new 10-inch underground pipeline be constructed, starting from the existing canal, ‘Lateral 4’ (near the corner of 9th Street and Kansas Avenue), and will run for approximately one mile to the WGS2 site. The new waterline will be buried in or adjacent to Kansas and Graphics Avenues.
