Hybrid plant configurations reflect their primary use cases: The relatively high average storage ratio and duration of PV+storage plants suggest that storage is providing resource adequacy (i.e., capacity firming) and energy arbitrage (i.e., shifting power sales from lower- to higher-priced periods) capabilities to PV+storage plants. In

In 2021, U.S. utilities in 42 states reported 1,094 MW of small-scale battery capacity associated with their customer''s net-metered solar photovoltaic (PV) and non-net metered PV systems.
READ MOREPumped storage hydropower (PSH) is a type of hydroelectric energy storage. It is a configuration of two water reservoirs at different elevations that can generate power as water moves down from one to the other (discharge), passing through a turbine. The system also requires power as it pumps water back into the upper reservoir (recharge).
