CPS Energy, the municipal electric utility of San Antonio, Texas, invites the submission of price bids for the supply of electric energy from operators, owners, and/or developers of utility scale renewable energy generation facilities located within the ERCOT region. All wind projects for consideration must provide predominately on-peak power; for example, coastal wind profile. Solar powered facilities may be sited in West Texas. This Request for Proposals (RFP) is seeking long term purchased power to supplement generation from existing CPS Energy facilities.

CPS Energy is considering the purchase of renewable energy generated from up to 200 megawatts (MW) along with the associated Renewable Energy Credits (RECs) for the units of energy generated. Renewable energy generating technologies include those such as wind, solar, bio-mass, landfill gas or any other renewable energy technology described in Texas Senate Bill 7, Sec. 39.904. This purchase will be structured to include the total output from a defined portion of one or more generation facilities, for a period of not less than fifteen (15) years and possibly as much as twenty (20) years or more. CPS Energy requires the entire amount of renewable capacity specified in the contract be available no later than December 31, 2011. This energy will be provided to CPS Energy at the contract price expressed in dollars per megawatt-hour ($/MWh). CPS Energy prefers this price to include the energy and RECs together.

The bids received will be evaluated and the best alternative will be selected that meets all environmental, technological, operational and financial requirements resulting in the best value to CPS Energy ratepayers over the time horizon studied. CPS Energy may waive irregularities and informalities in any proposals and reject any and all bids at its sole discretion and reserves the right to make no awards.
