  • INTRODUCTION

    A. SUMMARY OF THE DECISION

    This Decision sets forth the Commissions rationale in determining that the

    proposed Colusa Generating Station (CGS) complies with all applicable laws,

    ordinances, regulations, and standards (LORS), and may therefore be licensed.

    It is based exclusively upon the record established during this certification

    proceeding and summarized in this document. We have independently evaluated

    the evidence, provided references to the record1 supporting our findings and

    conclusions, and specified the measures required to ensure that the CGS is

    designed, constructed, and operated in the manner necessary to protect public

    health and safety, promote the general welfare, and preserve environmental

    quality.

    On November 6, 2006, E&L Westcoast, LLC (E&L W or Applicant), a subsidiary

    of Competitive Power Ventures, filed an Application for Certification (AFC)

    seeking approval from the California Energy Commission (Energy Commission)

    to develop the Colusa Generating Station (CGS). On December 13, 2006, the

    Energy Commission accepted the AFC as complete, thus starting the Energy

    Commissions formal review of the proposed CGS project. The CGS project is in

    response to Pacific Gas and Electric Companys (PG&E) Request for Offer and

    a contract agreement signed with the Applicant in 2006. The contract between

    PG&E and the Applicant would transfer the ownership and operation of the

    proposed power plant to PG&E after a license is issued and a commissioning

    phase of the facility is completed
