2015 Request for Offers Seeking CHP Power Purchase Agreements

Latest Update

In accordance with the Qualifying Facility (“QF”) and Combined Heat and Power (“CHP”) Program Settlement Agreement and related documents (including the CHP Program Settlement Agreement Term Sheet) approved by the California Public Utilities Commission (“CPUC”) on December 16, 2010 in Decision (D.)10-12-035 (collectively, the “Settlement Agreement”), San Diego Gas and Electric (“SDG&E”) is issuing its 2015 Combined Heat and Power (“CHP”) Request for Offers (“RFO”) to solicit offers (“Offers”) from owners and operators of CHP Facilities and Utility Prescheduled Facilities (“UPF”). The Settlement Agreement became effective November 23, 2011.

(“SDG&E”) is issuing this 2015 CHP RFO to achieve its megawatt (“MW”) and Greenhouse Gas (“GHG”) Emissions Reductions Targets, established in the CHP Program Settlement Agreement and further refined in D.15-06-028 – Decision on Combined Heat and Power Procurement Matters (“2015 CHP Decision”). This RFO solicits offers from owners and operators of CHP Facilities and UPFs.

Pursuant to the CHP Program Settlement, SDG&E seeks to acquire a total of 160 MW of CHP name plate Capacity under Power Purchase Agreements (“PPA” or “Agreements”) during the Initial Program Period (2011-2015) and 51 MW in the Second Program Period (2016-2020), both of which periods are defined in the CHP Program Settlement.  Through this solicitation, the third and final of three RFOs to be held during the Initial Program Period, SDG&E seeks offers to meet a CHP MW Target of up to 50 MW in order to make progress toward its Initial Program Period goal of 160 MW. SDG&E may consider offers larger than 50 MW depending on an offer’s overall attractiveness and contributions to meeting the CHP Settlement MW and GHG reduction goals. 

This solicitation sets forth the terms and conditions of SDG&E’s third CHP RFO. By responding to this RFO, the bidder agrees to be bound by all the terms, conditions, and other provisions of this RFO and any changes or supplements to it that may be issued by SDG&E, prior to the bidder’s response.

In this RFO, SDG&E will entertain offers for the following resources as defined in the CHP Program Settlement: Existing CHP, New CHP, Repowered CHP, Expanded CHP, and Existing CHP Facilities Converting to UPF. SDG&E will give preference for offers that are low cost, and have either low associated GHG emissions or provide GHG emissions reductions through changes in operations or technology. Any facility that offers operating flexibility will be considered favorably.
