According to a U.S. Energy Information Administration (EIA) update on the latest inventory of electricity generators, wind and solar will represent more than two-thirds of new energy production to come online in 2021, while battery storage capacity is set to quadruple over the next year.[1] 39.7 GW of new electricity generating capacity is set to start commercial operation in 2021. 15.4 GW of that capacity will be solar photovoltaic (PV), making it the largest source of new capacity at 39%. More than half of new utility-scale solar PV capacity is planned for four states: Texas (28%), Nevada (9%), California (9%), and North Carolina (7%). 12.2 GW of wind capacity is scheduled to come online in 2021, putting it at 31% of new capacity with more than half of additions in Texas and Oklahoma. This is a decrease from 2020, which saw 21 GW of wind come online. 4.3 GW of battery power capacity additions are expected to come online in 2021 which will more than quadruple battery storage capacity. About 3% of the new capacity in 2021 will come from the new nuclear reactor at the Vogtle power plant in Georgia. Planned natural gas capacity additions are set at 6.6 GW, with more than 70% of these planned additions in Texas, Ohio, and Pennsylvania.
