EIA: new natural gas-fired capacity additions expected to total 8.4 GW in 2023

The additions include both combined-cycle gas turbine (CCGT) plants and simple-cycle gas turbine (SCGT) plants concentrated near the Gulf Coast and Appalachia natural gas producing regions, and in Florida, US. In 2022, a total of 11 natural gas-fired power plants came online, adding 5.5 GW of capacity. Total natural gas-fired capacity additions increased in both 2022 and 2023 after consecutive declines in the prior three years.
In the next two years (2024 and 2025), 20 new natural gas-fired power plants are expected to come online with a total capacity of 7.7 GW.
CCGT plants commonly serve both base and peak electricity load because they are highly efficient and designed to run for extended periods of time. During 2022 and 2023, a total of 13 new CCGT plants with a combined capacity of 11.9 GW will have entered service. The average output for each of the 13 CCGT plants is 0.9 GW of electric generating capacity. Approximately 5.8 GW of the total capacity is located in Florida and Michigan, US. These two states already produce electricty primarily from natural gas-fired power plants.
During 2022 and 2023, 14 SCGT plants with total capacity of 1.9 GW will have begun operations. The average output for each of the 14 SCGT plants is 140 MW of electric generating capacity. Although the average capacity of SCGT plants is much lower than CCGT plants, SCGT plants are able to quickly ramp up operations in response to sudden changes in demand or when output from intermittent renewable energy sources is unavailable. Over half of the new SCGT capacity coming online in 2022 and 2023 is located in Texas, which has periods of high daily peak electricity demand throughout the summer and has had significant growth in renewable energy during the last few years. Additional new SCGT units with a total capacity of 2.8 GW, mostly located in Texas near high population areas, are expected to enter service in 2024 and 2025.
