Utility-Scale Solar Power Additions May Double In 2024: EIA Report

US New Solar Projects Report Fewer Delays In 2023: EIA

A latest report from the Energy Information Agency (EIA) on the preliminary monthly electric generator inventory shared the developers’ and power plant owners’ plan to add 62.8 gigawatts (GW) of new utility-scale electric-generating capacity in 2024. 

The EIA report found that 55% more capacity would be added than the 40.4 GW added in 2023 (the most since 2003), pointing to a continued rise in industry activity. The firm expects solar to account for the largest share of new capacity in 2024, at 58%, followed by battery storage, at 23%.

It shared plans in the solar sector. It said, “We expect a record addition of utility-scale solar in 2024 if the scheduled 36.4 GW are added to the grid. This growth would almost double last year’s 18.4 GW increase, which was itself a record for annual utility-scale solar installation in the United States. As the effects of supply chain challenges and trade restrictions ease, solar continues to outpace capacity additions from other generating resources.”

It added, “More than half of the new utility-scale solar capacity is planned for three states: Texas (35%), California (10%), and Florida (6%). Outside of these states, the Gemini solar facility in Nevada plans to begin operating in 2024. With a planned photovoltaic capacity of 690 megawatts (MW) and battery storage of 380 MW, it is expected to be the largest solar project in the United States when fully operational.”

In battery storage, it forecasts, “We expect battery storage to set a record for annual capacity additions in 2024. We expect U.S. battery storage capacity to nearly double in 2024 as developers report plans to add 14.3 GW of battery storage to the existing 15.5 GW this year. In 2023, 6.4 GW of new battery storage capacity was added to the U.S. grid, a 70% annual increase.”

Planned utility scale electric generation

Texas, with an expected 6.4 GW, and California, with an expected 5.2 GW, can account for 82% of the new US battery storage capacity. Developers have scheduled the Menifee Power Bank (460.0 MW) at the site of the former Inland Empire Energy Center natural gas-fired power plant in Riverside, California, to come online in 2024.

With the rise of solar and wind capacity in the United States, the demand for battery storage continues to increase. The Inflation Reduction Act (IRA) has also accelerated the development of energy storage by introducing investment tax credits (ITCs) for stand-alone storage. Before the IRA, batteries qualified for federal tax credits only if they were co-located with solar.

The EIA report said that wind operators report another 8.2 GW of wind capacity is scheduled to come on line in 2024. Following the record additions of more than 14.0 GW in both 2020 and 2021, wind capacity additions have slowed in the last two years.

Two large offshore wind plants scheduled to come online this year are the 800-MW Vineyard Wind 1 off the coast of Massachusetts and the 130-MW South Fork Wind off the coast of New York. South Fork Wind, which developers expected to begin commercial operation last year, is now scheduled to come online in March 2024.
