California Title 24 establishes statewide building standards designed to improve energy efficiency, safety, and overall building performance. Within these standards, energy storage can play an important role in supporting buildings equipped with solar photovoltaic (PV) systems.
Battery Energy Storage Systems (BESS) can work alongside solar PV installations to store excess energy for use when it is most needed. Depending on the applicable building type, system configuration, and current code requirements, energy storage provisions may apply to new construction and certain building projects.
Beyond supporting compliance, an energy storage system can provide practical benefits such as backup power, peak demand management, load shifting, and improved utilization of on-site renewable energy. These capabilities can help building owners increase energy resilience while making better use of available solar generation.
As California continues to advance its clean-energy and building-efficiency goals, properly designed energy storage systems can serve as an important component of modern, resilient building infrastructure.
