Small-scale battery energy storage. EIA''s data collection defines small-scale batteries as having less than 1 MW of power capacity. 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.
However, the new regulations with symmetric reserve products and the ESS''s charges to provide downward regulation energy were not modeled. None of the existing works have considered all types of reserves [37], particularly manual reserves such as mFRR or RR in the European market, as a potential revenue stream for BESS.
