US utility-scale solar capacity additions hit 36.4 GW in 2023

From pv magazine USA

The EIA has released its Preliminary Monthly Electric Generator Inventory, featuring projections for high-probability electric generation capacity additions for 2024. 

The EIA expects nearly 63 GW of new capacity this year – significantly more than the 40 GW added in 2023. Last year was the largest boom in grid capacity additions since 2023, and 2024 is set to blow that out of the water. 

What’s more, solar and batteries are dominating the project queues. Solar represents 58% of expected capacity additions in 2024, and batteries take second place with 23% of the mix. This represents a record 36.4 GW of solar and 14.3 GW of battery energy storage. These figures only include utility-scale projects, meaning solar has an even larger piece of the pie when including distributed solar like rooftop residential and commercial behind-the-meter projects. 

The EIA’s 36.4 GW projection of utility-scale solar nearly doubles last year’s 18.4 GW increase, which was already a new deployment record.  

Texas is expected to be the head-and-shoulders frontrunner, adding 35% of the nation’s utility-scale solar in 2024. It is followed by California at 10% and Florida at 6%. 

Meanwhile, total cumulative battery energy storage is expected to nearly double this year. In its entire history, the United States has installed about 15.5 GW of grid-scale batteries. The EIA expects 14.3 GW more storage to be installed and operational in 2024. 

The two leading technologies are followed by wind (13%), natural gas (4%), and nuclear (2%). There zero coal-fired plants planned in 2024, and more decommissioning projects are on the way.
