Silicon Valley Clean Energy (SVCE) and Peninsula Clean Energy (PCE) are seeking qualified service providers to help provide and expand demand flexibility services in their service areas over the next five years. The RFP has two distinct parts: Part 1 targets procurement of 5 MW per CCA (10 MW total) or more of existing capacity from customers' flexible loads by 2026 in the form of market-integrated or load modifying capacity. Part 2 seeks service providers to develop an additional 25 MW per CCA (up to 50 MW total) of demand flexibility by 2030 through a combination of different approaches, including traditional demand response, load-modifying programs, and dynamic pricing. Key device types include electric vehicles (EVs), battery energy storage systems (BESS), heat pump water heaters (HPWHs), smart control thermostats (SCT), and non-residential building energy management systems (BEMS). The CCAs are actively investing in electrification of transportation and buildings in their communities and anticipate significant future growth in electricity demand. A key objective is creating an 'on-ramp' for connecting and flexing new loads resulting from the CCAs' electrification and decarbonization programs. The CCAs envision a minimum 5-year demand flexibility effort, with a centralized DERMS solution to manage a variety of flexible technologies.
