2021 Distribution Investment Deferral Framework (“DIDF”) Solicitation



In accordance with Decision (“D.”)16-12-036 – Decision Addressing Competitive Solicitation Framework and Utility Regulatory Incentive Pilot (the “Integrated Distributed Energy Resources Incentive Pilot Decision”) issued on December 22, 2016 and Resolution (“R.”) E-4889 adopted on December 14, 2017, San Diego Gas & Electric Company (“SDG&E”) is issuing its 2021 Distributed Investment Deferral Framework (“DIDF”) Request for Offers (“RFO”) to solicit offers from owners and operators of Energy Efficiency (“EE”) programs, Demand Response (“DR”) programs, renewable generation resources, Energy Storage (“ES”) resources and/or other Distributed Energy Resources (“DERs”).  These DERs must be operated, installed, implemented and connected, In-Front-of-the-Meter (“IFM”) and/or Behind-The-Meter (“BTM”), to circuit number 1202.  DERs included in an Offer must satisfy the Commission’s incrementality requirements as set forth in Ordering Paragraph 10 of D.21-02-006.

These resources are being sought by SDG&E in order to defer the distribution project that otherwise would have been completed in order to maintain system safety and reliability (that is, traditional distribution upgrades or build out).
