New Power Generation Quarterly: 2022 Q4

Date: 16 Mar 2023 | posted in: Energy, Energy Self Reliant States | 0 Facebooktwitterredditmail

8.4 gigawatts of new power generation capacity came online in the fourth quarter of 2022. 60 percent of that total, or nearly six gigawatts, was new solar power. Wind power generation capacity grew steadily with 3.4 gigawatts, while developers only built 169 megawatts worth of gas-fired power plants.

In the chart below, we illustrate the past two years of new electric power capacity in the U.S., disaggregated by energy source on a quarterly basis.

Key takeaways:

  • 3.5 gigawatts of new wind capacity (all onshore) came online in the fourth quarter.
  • The fourth quarter of 2022 was the slowest quarter in two years for gas plant buildout.
  • 61 percent of power generation capacity added to the grid this quarter was from solar: 3.8 gigawatts of utility-scale solar and just under 2 gigawatts of small solar.
  • The growth of distributed solar, in particular, accelerated in each quarter of 2022, with the fourth quarter culminating in well over a gigawatt of residential solar alone.
  • 1,976 megawatts sets a new quarterly record for small solar buildout.
  • Developers built over a gigawatt of utility-scale energy storage this quarter, which paired with solar and wind, provides energy resilience and grid stabilization.
