According to the US Department of Energy’s EIA, the United States connected 20.2 GW (AC) of utility-scale power plants to the grid during the first half of 2024. This capacity includes 12 GW of solar, which represents 59% of the total additions. Energy storage accounted for about 4.2 GW of this new capacity.
Florida and Texas led the nation in utility-scale solar development, contributing 38% of the new solar capacity. Notable projects include the 690 MW Gemini Solar facility in Nevada, which integrates solar and storage, and the 653 MW Lumina Solar Project in Texas.
Energy storage was the second most significant technology by capacity with a total deployment of 4.2 GW. California led the charge, contributing 37% of the total energy storage capacity, followed by Texas (21%), Arizona (19%), and Nevada (13%). Together, these states accounted for 90% of the energy storage capacity added, with the 380 MW battery at the Gemini facility being the largest of the period.
Fossil fuel retirements far outpaced new fossil capacity deployments. The EIA noted that 5.1 GW of capacity was retired, with 53% from methane (2.7 GW) and 41% from coal (2 GW). In contrast, only 0.4 GW of new gas capacity was deployed.
The US energy sector’s growth trajectory is expected to continue its upward trend. For the second half of the year, the EIA forecasts an additional 42.6 GW from new capacity deployments, including 25 GW from solar and an additional 10.8 GW of energy storage. Combined with the first-half capacity of 12 and 4 GW, the nation could finish 2024 with 37 GW of new utility-scale solar and 15 GW of new energy storage facilities.
