Large California Utility Launches Thermal Energy Storage Program

A large California utility faced unprecedented challenges from intermittent generation sources, weather emergencies, and wildfire risks. Capital investments in infrastructure would require a lengthy regulatory approval process with deployment projects taking several years to execute. The utility received approval from the California Public Utilities Commission (CPUC) to launch a distributed energy storage program expected to be one of the largest of its type in the U.S. with a goal “to achieve ratepayer benefits, reduce dependence on petroleum, meet air quality standards, and reduce emissions of greenhouse gases.”

Armada’s regulatory affairs team provided guidance and supporting data to the CPUC process covering the economic and technical contributions of active water heater control. The utility selected the Association for Energy Affordability (AEA) to manage the program. Upon review of Armada’s proposal outlining the financial, technical, and consumer impact of the solution, Armada was awarded a contract, and initial unit orders were placed and shipped.
