How many GW of solar generating capacity will come online in 2026?

Almost 70 gigawatts (GW) of new solar generating capacity projects are scheduled to come online in 2026 and 2027, which represents a 49% increase in U.S. solar operating capacity compared with the end of 2025. Much of the utility-scale solar generation capacity additions will come online in Texas.

How many solar energy systems are there in the US?

US solar electricity usage led to an increased demand in solar-based electricity generation. According to SEIA (Solar Energy Industries Association), about 5,425,045 solar energy systems are installed in the U.S. as of 2025. U.S. plans to expand its existing solar capacity by targeting 500 GW of additional solar capacity by 2035.

Is solar power the future of electricity generation?

Solar continues to dominate new electricity generation capacity added to the grid in the United States, according to the Energy Information Administration's (EIA) latest release of its Electric Power Monthly report with data through March 2025.

Will solar power and wind power grow in 2027?

We expect the combined share of generation from solar power and wind power to rise from about 18% in 2025 to about 21% in 2027. In our STEO forecast, utility-scale solar is the fastest-growing source of electricity generation in the United States, increasing from 290 BkWh in 2025 to 424 BkWh by 2027.
