Pacific Gas and Electric Company (PG&E) and San Diego Gas & Electric (SDG&E) are working with Swell to expand residential participation in their respective Capacity Bidding Programmes. Through these programmes, homeowners with solar + storage systems can receive compensation for supporting overall grid reliability while maintaining reserves in their battery for emergency use. These efforts support the California Public Utility Commission's goal of reducing load during California Independent System Operator emergency power events.
For PG&E, Swell will enroll existing and new residential solar + storage customers into the Capacity Bidding Programme and collectively manage the systems to provide needed capacity during times of high demand or high wholesale market prices. For SDG&E, Swell is expanding residential participation in its programme, which was previously only offered to commercial and industrial customers. In addition, Swell is helping SDG&E evaluate different scenarios in which residential solar + storage systems could be used to improve the overall reliability of the grid in the context of SDG&E’s specific goals and constraints.
The programmes have resonated with customers who value the opportunity to give back with their home solar + storage systems.
Swell is also working on innovative virtual power plant applications with Southern California Edison (SCE). In addition to the two existing virtual power plants Swell has with SCE, the smart grid solutions provider is facilitating expanded applications for residential solar + storage assets to balance energy on the grid across a number of different scenarios and use cases. The effort with SCE could expand the use of aggregated residential solar + storage resources into virtual power plants to maximise environmental benefits and improve power reliability for SCE customers.
All three programmes align with California Public Utility Commission goals to improve power reliability in the face of more frequent extreme weather events. By expanding residential participation in utility capacity programs and helping utilities maximise the benefits distributed solar + storage systems can provide, Swell is helping meet the state’s projected energy needs next summer and beyond. With the right grid services and participation levels, these programmes help utilities and the California Public Utilities Commission meet California’s mandates for renewable energy while improving power reliability and minimising costs to ratepayers associated with building additional standby ‘peaker plants’ that are infrequently used.
