Aliso Canyon Energy Storage

SCE is pleased to announce the launch the 2016 Aliso Canyon Energy Storage Request for Offers ("2016 ACES RFO") and the 2016 Aliso Canyon Design, Build, and Transfer Request for Proposals ("2016 DBT RFP"). SCE is launching these activities in response to Resolution E-4791, issued to address electrical reliability risks due to the moratorium on injections into the Aliso Canyon Natural Gas Storage Facility.

The 2016 ACES RFO is for Products from eligible Energy Storage Resources ("ESRs") and is open to energy storage resource facilities as defined in CPUC Decision 13-10-040. ESRs must not be less than 0.5 megawatt (MW) and must be fully-deliverable transmission or distribution connected market resources.

The 2016 DBT RFP is a solicitation for proposals to design, build, and transfer to SCE energy storage systems ready for placement into commercial operation, including performance guarantees, on a fixed-price, turnkey basis, and separately, additional maintenance services. Proposals with guaranteed discharge powers of 5, 10, 15, and 20 MW (if within the seller capabilities), each with a guaranteed discharge duration of at least 4 hours, and each with 5, 10, 15, and 20 year periods of guaranteed performance are solicited.
