Power plant developers and operators will add 51 gigawatts (GW) of new solar and battery projects to the US power grid from 2022 to 2023, representing 60% of new generation capacity, according to the US Energy Information Administration. EIA).

A look at the December 2021 EIA spreadsheet shows that the remaining 40% is primarily composed of onshore wind (15 GW) and natural gas (16 GW).
In 2021, renewable energy and batteries have increased significantly in the United States. According to the EIA, this was due to tax incentives and declining technology costs, especially batteries.
General purpose solar accounts for 41 GW (48%) of planned capacity in the United States over the next two years. More utility-scale solar (24 GW) than natural gas (12 GW) was added to the US grid between 2020 and 2021, and the EIA expects this trend to continue over the next two years.
In 2022, power plant developers and operators expect to add 22 GW of solar capacity to the grid, much more than the 13 GW added in 2021. investment tax credit: 26% in 2021 and 2022, 22% in 2023 and 10% in 2024 and beyond.
Power plant developers and operators expect to add 10 GW of battery capacity over the next two years. More than 60% of this power will come from solar energy. In 2021, 3.1 GW of batteries were added in the US, a 200% increase. This surge was driven by lower battery storage costs, as well as favorable economics as the technology rolls out with wind and solar.
More than half of the 51 GW of solar and battery storage planned over the next two years will come from just three states: Texas with 12 GW (23%), California with 11 GW (21%) and New York with 4 GW (7%) .
