| Starting in 2023, capacity and energy capacity is now collected for batteries. Prior to 2023, the battery historical data was listed as storage. Starting in 2018, PV Capacities have been converted to AC. Starting in 2016, Capacity is now collected by technology and sector. Starting in 2013, the residential sector is now included and all net metering units are excluded. Distributed generators are generators which are connected to the grid. They may be installed at or near a customer`s site or at other locations. They may be owned by either the customers of the distribution utility or by the utility. Other includes generators for which technology is not specified. Totals may not equal sum of components because of independent rounding.
