More solar will be connected to the U.S. grid than wind power within three years

The majority of new utility-scale electricity generating capacity added in the first six months of 2023 in the United States came from solar and wind. This is according to a review by the SUN DAY Campaign of newly released data by the Federal Energy Regulatory Commission (FERC).

In its latest monthly “Energy Infrastructure Update” report (with data through June 30, 2023) FERC reports that of the 17,017 MW of new generating capacity placed in service during the first half of 2023, 5,867 MW (34.48%) came from solar and another 2,750 MW (16.16%) from wind for a combined total of 50.64%. Including new capacity from hydropower (254 MW), geothermal (44 MW) and biomass (30 MW), the mix of renewables accounted for 52.57% of the new generation added. Most of the balance came from 8,025 MW of natural gas (47.16%). The rest was comprised of 16 MW of new oil capacity and 31 MW of waste heat.

The new solar capacity added between January and June was more than that for the first half of any prior year reported by FERC. Utility-scale solar is now 6.97% of total available installed generating capacity in the United States. Wind is another 11.62%. Taken together, the mix of all renewables now accounts for 28.06% of the total. A year earlier, that number was 26.74% while five years ago it was 20.67%. Thus, renewables are adding about 1.5% each year to their percentage share of the nation’s generating capacity. And that growth may be accelerating.

Over the next three years, FERC anticipates “high probability additions” of solar to provide another 81,284 MW while wind is expected to expand by 19,734 MW. Assuming that materializes, in three years, solar and wind combined would provide over a quarter (26.01%) of U.S. generating capacity. Wind would account for 12.41% of installed capacity while utility-scale solar would provide another 12.60% . That is, installed solar capacity is poised to overtake that of wind within three years, making it the largest renewable source by capacity. And that does not include generating capacity provided by small-scale, distributed solar.

Factoring in FERC’s forecasts for hydropower, geothermal, and biomass, renewable energy sources would expand from today’s 28.06% of installed generating capacity to 33.99% by June 2026.

For perspective, utility-scale solar’s share of U.S. generating capacity by June 2026 could be more than four times that of oil (2.68%), substantially greater than that of nuclear power (7.58%), and nearly equal to that of coal (13.95%).

Solar and wind’s share of U.S. generating capacity could actually be substantially higher if new capacity exceeds FERC’s forecast of “high probability additions.” The agency indicates that the amount of solar and wind in the three-year pipeline could be nearly three times higher than the total of the “high probability additions.” Solar could add 214,563 MW while wind could grow by 66,286 MW.

Moreover, recent history suggests that solar and wind growth is outpacing FERC’s predictions for “high probability additions.” A year ago, FERC forecast “high-probability additions” for wind and solar within three years of 17,225 MW and 66,315 MW, respectively. FERC’s latest three-year outlook for those sources is now more than one-fifth (20.9%) higher.

Meanwhile, if just FERC’s “high probability” forecasts materialize, by June 2026, installed U.S. fossil fuels’ share of total capacity will drop significantly: natural gas – 41.65% (from 44.41% in June 2023), coal – 13.95% (from 16.43%), and oil – 2.68% (from 2.87%). Nuclear power will also fall from 8.06% today to 7.58% in June 2026.

“Solar and wind combined continue to add more new capacity to the nation’s electrical generating mix than any other energy source,” noted the SUN DAY Campaign’s executive director Ken Bossong. “Within three years, they will each account for over an eighth of U.S. generating capacity while the combination of all renewable sources will be over a third.”
