54.5 GW of new power coming online in 2023 in U.S.

Utility-scale battery storage capacity expected to more than double

The U.S. Energy Information Administration (EIA) reports that 54.5 GW of new utility-scale electric-generating capacity is expected to be added to the U.S. power grid in 2023.

Of that, more than half of this capacity will be solar power (54%), followed by battery storage (17%).

The EIA reports that U.S. utility-scale solar capacity has been rising rapidly since 2010. “Despite its upward trend over the past decade, additions of utility-scale solar capacity declined by 23% in 2022 compared with 2021,” the EIA reports. “This drop in solar capacity additions was the result of supply chain disruptions and other pandemic-related challenges. We expect that some of those delayed 2022 projects will begin operating in 2023, when developers plan to install 29.1 GW of solar power in the United States.”

If all of this capacity comes online as planned, 2023 will have the most new utility-scale solar capacity added in a single year, more than doubling the current record (13.4 GW in 2021).

In 2023, the most new solar capacity will be in Texas (7.7 GW) and California (4.2 GW), together accounting for 41% of planned new solar capacity.

U.S. battery storage capacity has grown rapidly over the past couple of years, the EIA said.

“In 2023, U.S. battery capacity will likely more than double,” the EIA estimates. “Developers have reported plans to add 9.4 GW of battery storage to the existing 8.8 GW of battery storage capacity.”

In 2023, 71% of the new battery storage capacity is expected to be in California and Texas, states with significant solar and wind capacity.

Developers plan to build 7.5 GW of new natural-gas fired capacity in 2023, 83% of which is from combined-cycle plants. The two largest natural gas plants expected to come online in 2023 are the 1836 (MW) Guernsey Power Station in Ohio and the 1214 MW CPV Three Rivers Energy Center in Illinois.

In 2023, developers plan to add 6.0 GW of utility-scale wind capacity. Annual U.S. wind capacity additions have begun to slow, following record additions of more than 14 GW in both 2020 and 2021.

The most wind capacity will be added in Texas in 2023, at 2.0 GW. The only offshore wind capacity expected to come online this year is a 130.0 MW offshore windfarm in New York called South Fork Wind.

Two new nuclear reactors at the Vogtle nuclear power plant in Georgia are scheduled to come online in 2023, several years later than originally planned. The reactors, with a combined 2.2 GW of capacity, are the first new nuclear units built in the United States in more than 30 years.
