Utility-scale solar and wind each added more generating capacity than natural gas during the first nine months of 2022, according to a SUN DAY Campaign review of FERC data. FERC’s latest three-year forecast suggests that installed natural gas capacity will begin to decline by 2025 while solar and wind continue to rapidly expand.
Solar (6,751 MW) and wind (6,328 MW) each provided more new generating capacity during the first three-quarters of this year than did natural gas (6,086 MW). Combined with capacity additions by geothermal (90 MW), biomass (22 MW) and hydropower (14 MW), renewable energy sources accounted for 13,205 MW or 68.4% of the 19,316 MW of new generation put into service this year.
Besides natural gas, the balance came from nuclear power (17 MW) and oil (8 MW). No new capacity was reported for 2022 from coal.
In addition, solar provided 82.7% (487 MW) of the new capacity reported in September alone. This includes the 275.0-MW Noble Solar & Storage Project in Denton County, Texas, and the 150.0-MW Wood County Solar Project in Wood County, Wisconsin, among others. Also added in September was 99 MW of new natural gas capacity and 3 MW of new hydropower.
These recent additions bring renewable energy’s share of total U.S. available installed generating capacity up to 26.96%:
- wind – 11.23%
- hydropower – 8.05%
- solar – 6.14%
- biomass – 1.22%
- geothermal – 0.32%.
For comparison, five years earlier, renewables’ share was 19.84%. Ten years ago, it was 14.79%.
FERC reports that there may be as much as 206,184 MW of new solar capacity in the pipeline with 71,617 MW classified as “high probability” additions and no offsetting “retirements.” The “high probability” additions alone would nearly double utility-scale solar’s current installed capacity of 77,210 MW, while successful completion of all projects in the pipeline would nearly quadruple it.
Arguably more startling is FERC’s forecast for natural gas capacity over the next three years. FERC anticipates 107 units of “high probability” additions by natural gas by September 2025 totaling 17,062 MW of capacity. However, there will also be “retirements” of 130 units totaling 17,489 MW. If that materializes, installed natural gas capacity would actually decline, very possibly indicating that natural gas generating capacity has now peaked.
FERC expects new nuclear additions to total 2,200 MW (two new reactors being constructed at the Vogtle nuclear plant site near Waynesboro, Georgia). However, FERC also projects that nuclear retirements over the next three years will total 2,323 MW. In addition, FERC reports no new coal generating capacity in the three-year pipeline but 19,106 MW of expected retirements. Oil generating capacity is projected to fall by 1,710 MW as well.
“FERC’s latest data may be the most dramatic published thus far this year,” noted the SUN DAY Campaign’s executive director Ken Bossong. “A sharp increase in FERC’s three-year forecast for wind and solar within just the last month coupled with an apparent peaking of natural gas seem to confirm that the nation has finally turned a corner on its transition to sustainable energy sources.”
