California Energy Commission Letterhead





On November 18, 2008, CPV Vacaville, LLC filed an Application for Certification (AFC) seeking authority to construct and operate the CPV Vaca Station Project (CPVV), a natural gas-fired, combined-cycle electrical generating facility rated at a nominal generating capacity of 660 megawatts (MW). The CPVV is proposed for a 24-acre site located at the intersection of Lewis and Fry roads in a rural area within the city limits of Vacaville, Solano County, California. Surrounding land uses include the City of Vacaville's (City) wastewater treatment plant to the northwest and agricultural uses to the east, west, and south.

The Energy Commission has exclusive jurisdiction to license this project and is considering the proposal under a twelve-month review process established by Public Resources Code section 25540.6. The power plant licensing process, which incorporates requirements equivalent to those of the California Environmental Quality Act (CEQA), considers all relevant engineering and environmental aspects of the proposed project. The licensing review provides a public forum allowing the Applicant, Commission staff, governmental agencies, adjacent landowners, and members of the public to consider the advantages and disadvantages of the project, and to propose changes, mitigation measures, and alternatives as necessary.

PLEASE TAKE NOTICE that the Committee assigned to this proceeding has scheduled a public Site Visit and Informational Hearing to discuss the proposed project as described below:

Public Site Visit begins at 4:00 p.m.
Public Informational Hearing begins at 5:00 p.m.

Easterly Wastewater Treatment Plant
Administration and Control Building
Assembly Room, 1st floor
6040 Vaca Station Road
Elmira, California 95625
Wheelchair Accessible
See Map

Members of the public are invited to join the Committee on a tour of the proposed site before the Informational Hearing. For site visit reservations, please contact the Commission's Public Adviser's Office, at (916) 654-4489 or 1-800-822-6228 or e-mail: Please make your reservation on or before March 5, 2009, so that we can assure you a space.


On November 18, 2008, CPV Vacaville, LLC submitted an AFC to the California Energy Commission to construct and operate an electrical generating plant in the city of Vacaville, Solano County, California. The proposed CPV Vaca Station Project (CPVV) is a combined-cycle, nominal 660 MW power generation facility. On December 18, 2008, the Energy Commission determined that the CPVV Project did not meet all the requirements listed in Title 20, section 1704, and Division 2, Chapter 5, Appendix B of the California Code of Regulations, for the 12-month process. Specifically, the AFC was deficient in seven of the 23 technical areas reviewed: Air Quality, Cultural Resources, Land Use, Noise, Traffic and Transportation, Transmission System Design, and Visual Resources. On January 9, 2009, CPVV filed an AFC Data Adequacy Supplement B to the AFC containing the required information for review. Staff reviewed the supplemental information and determined that the AFC met the listed requirements in all seven of the previously deficient technical disciplines.

On January 28, 2009, the Energy Commission began review of the proposed CPV Vaca Station Project. The review process will take approximately twelve months. During the review period, the Energy Commission will determine whether the proposed project complies with applicable laws related to public health and safety, environmental impacts, and engineering requirements. The informational hearing scheduled by this Notice is sponsored by the Energy Commission to inform the public about the project and to invite public participation in the review process.

Project Description

The proposed project would be located on a 24-acre portion of a larger 143-acre parcel owned by the city of Vacaville, located at the intersection of Lewis and Fry roads in a rural area within the city limits. On the northwest border of the site is the city of Vacaville's Easterly Wastewater Treatment Plant (EWTP), and to the east, west, and south is agricultural land. The project would include two combustion turbine-generators (CTGs - either two General Electric Frame 7FA, or two Siemens SGT6 5000), a single condensing steam turbine generator (STG), a deaerating surface condenser, a 12-cell mechanical draft cooling tower, and associated support equipment, heat recovery steam generators (HRSGs), emission reduction system with a selective catalytic reduction (SCR) unit to control NOx stack emissions and an oxidation catalyst to control carbon monoxide and volatile organic compounds emissions, a 1,000-kilowatt (kW), diesel-fired emergency generator, and would use reclaimed secondary-treated wastewater (1,185 million gallons per year) from the Easterly Wastewater Treatment Plant. The project would also use a small amount of the local municipal drinking water for plant personnel potable water uses. If approved, construction of the project would begin in the Spring of 2011 and would last for 30 months. Pre-operational testing of the power plant would begin in the fall of 2012 with full-scale commercial operation commencing by spring 2013.

The engineering and environmental details of the proposed project are contained in the AFC. Copies of the AFC are available at the local public agencies that are involved in the review process and at the following libraries:

Vacaville Public Library - Cultural Center
1020 Ulatis Drive
Vacaville, CA 95687

Vacaville, CA 95688

Copies are also available at the Energy Commission's Library in Sacramento, the California State Library in Sacramento, and at public libraries in Eureka, San Francisco, Fresno, Los Angeles, and San Diego.

Purpose of the Site Visit and Informational Hearing

The site visit and informational hearing scheduled in this Notice provides an opportunity for members of the community in the project vicinity to obtain information, to offer comments, and to view the project site. The Applicant will explain plans for developing the project and the related facilities and the Energy Commission staff will explain the licensing process and Staff's role in reviewing the AFC.

Proposed Schedule and Issue Identification Report

Commission staff will file a proposed schedule for project review. Staff will also file an Issue Identification Report summarizing the major issues. This report will also indicate what additional information is necessary to resolve issues of concern. The proposed schedule and Staff's report shall be filed by noon on March 4, 2009. The Applicant shall file its response, if any, by noon on March 9, 2009.
