On April 29, 2004, Riverside Public Utilities (RPU) filed an application for a Small Power Plant Exemption (SPPE). RPU is seeking an exemption from the California Energy Commission's licensing requirements. If an exemption is granted, the applicant would need to secure the appropriate licenses and permits for the project from various local, state and federal agencies.

RPU proposes to build and operate a nominal 96 MW simple-cycle power plant on a 12-acre fenced site within the City of Riverside, California. This proposed facility is referred to as the Riverside Energy Resource Center (RERC). RPU would develop, build, own and operate the facility. The proposed site is owned by the City of Riverside and is adjacent to the City's Waste Water Treatment Plant (WWTP) in a light industrial/manufacturing area. The WWTP is located on the west side of the Project and includes a 3.3 MW cogeneration facility. The cogeneration plant at the WWTP would be the source of power to black start the RERC plant. The two facilities would be cross-tied for both electrical power and compressed air. The power plant and associated administration building and warehouse would occupy approximately 8 of the 12 acres with the additional 4 acres reserved for equipment storage and construction parking. The power plant and associated administration building and warehouse would occupy approximately 8 of the 12 acres with the additional 4 acres reserved for equipment storage and construction parking.

The plant would consist of two General Electric LM6000 PC SPRINT combustion turbine generators equipped with inlet air chiller coils, exhaust ducting, flue gas treatment system to meet the proposed air emission limits, a common chiller package with cooling tower, gas compressor equipment, water storage and treatment facilities, emission monitoring system, zero liquid discharge (ZLD) wastewater treatment system and electrical transmission and interconnection system and associated auxiliary systems and equipment.

The proposed project would include the construction of approximately 1.75 miles of new double circuit 69kV transmission line interconnecting RERC to the Mountain View and Riverside substations. All transmission line construction would occur in an existing transmission line right-of-way. No new residential property easements are proposed.

Natural gas fuel would be supplied to RERC from a Sempra transmission line that passes next to the northeast corner of the site boundary. A short (~140') natural gas service line would be constructed to connect from the existing Sempra transmission pipeline to the onsite meter station.

Potable water for sanitary use would come directly from the City's general water supply. The adjacent WWTP would supply reclaimed water for plant process and cooling water. The RERC would utilize a Zero Liquid Discharge (ZLD) system that would eliminate the need to discharge process wastewater to the WWTP.

The Energy Commission is responsible for reviewing and ultimately approving or denying all thermal electric power plants, 50 MW and greater, proposed for construction in California. The Energy Commission's SPPE process allows projects between 50 and 100 MW to proceed with local approval rather than requiring an Energy Commission license. An exemption from this licensing process is available if the Energy Commission finds that the project would not create a substantial adverse impact on the environment or energy resources. The Energy Commission is the lead agency under the California Environmental Quality Act (CEQA), and would prepare an Initial Study that examines public health and safety, and environmental impacts of the proposed project including all related facilities such as electric transmission lines, natural gas pipelines, and waterlines.


Over the next four months, the Energy Commission will conduct a number of public workshops and hearings to determine whether the exemption request should be approved and under what set of conditions. These workshops provide the public and local, state and federal agencies the opportunity to ask questions and provide input about the proposed project. The Energy Commission will issue notices for these workshops and hearings, normally 14 days, but in no case later than 10 days prior to the meeting. If you are not currently receiving these notices and want to be placed on the mailing list, please contact Angela Hockaday, Project Secretary, at (916) 654-3925 or e-mail at

If you would like information on how to participate in the Energy Commission's review process for the proposed project, please contact Ms. Margret Kim, the Energy Commission's Public Adviser, at (916) 654-4489 or toll free in California at (800) 822-6228.

Technical or project schedule questions should be directed to James W. Reede, Jr. Ed.D, the Energy Commission's Project Manager at (916) 653-1245 or by e-mail to The status of the project, copies of notices, the SPPE application and other relevant documents would be placed on the Energy Commission's web site at

This notice of receipt has been mailed to all parties that have requested to be placed on the mailing list during pre-filing, and to property owners located adjacent to the project site or any of the project-related facilities. By being on the mailing list, you would receive notices of all project-related activities and notices when documents related to the project's review are available. You can also subscribe to receive e-mail notification of all notices at If you want your name removed from the mailing list, please contact Angela Hockaday Project Secretary, at (916) 654-3925, or e-mail at

A copy of the SPPE application document is available for public inspection at the:

Riverside Main Library
3581 Mission Inn Ave.
Riverside, CA 92501

Arlington Branch Library
9556 Magnolia Ave.
Riverside, CA 92503

Copies are also available at the Energy Commission's Library in Sacramento, the California State Library in Sacramento, and at public libraries in Los Angeles, San Francisco, San Diego, and Eureka. In addition, copies would be distributed to those public agencies that would retain jurisdiction if an exemption is granted by the Energy Commission.
