Includes both standalone and hybrid capacity.
*Approximate because hybrid storage capacity was estimated for some projects.
Supplementary notes
According to the source, interconnection queue data through the end of 2022 was compiled for seven independent system operators (ISOs) and 35 utilities, serving about 85 percent of all U.S. electricity load. Only includes "active" projects in interconnection queues, and "operational" and "withdrawn" projects when available.

Power capacity in interconnection queues in leading U.S. states 2022, by source
Texas accounted for the largest cumulative electricity capacity in interconnection queues in the United States in 2022. The southern state had approximately *** gigawatts of solar power capacity and ** gigawatts of energy storage projects waiting to be connected to the grid.
Overall, roughly two terawatts worth of electricity storage or generation capacity were in interconnection queues in the U.S. that year.
