As of the end of 2022, the total nameplate power capacity of operational utility-scale battery energy storage systems (BESSs) in the United States was 8,842 MW and the total energy capacity was 11,105 MWh. Most of the BESS power capacity that was operational in 2022 was installed after 2014, and about 4,807 MW was installed in 2022 alone.

In 2022, the United States had four operational flywheel energy storage systems, with a combined total nameplate power capacity of 47 MW and 17 MWh of energy capacity. Two of the systems, one in New York and one in Pennsylvania, each have 20 MW nameplate power capacity and 5 MWh of energy capacity.
With DC-coupled energy storage, the energy storage system can operate and maintain the DC bus voltage when the PV inverter is offline for scheduled or unplanned outages, allowing energy from the array to flow to the batteries and ensuring energy can be harvested for later use.
Adding DC-coupled energy storage allows for the capture of this generated energy from the margins. This capability is only available with a DC-DC converter that has voltage source capability.
