WHAT THEY WANT

(Summarized from the RFP)

The City of Corona Utilities Department, which runs a small municipal electric utility serving approximately 2,000 customers, is seeking a consultant to conduct a comprehensive feasibility study of battery energy storage systems (BESS) at its five Wholesale Distribution Access Tariff points of delivery with Southern California Edison. The utility participates in the California Independent System Operator market, with annual consumption of about 86,454 MWh and a coincident system peak load of 17.3 MW. The City wants to know whether storage could cut energy costs through load and peak-period management, mitigate energy exports and backfeed, and provide capacity, market or reliability benefits, and it needs a clear recommendation on whether to proceed.
