US nuclear outages fall to 16.0 GW on Nov 12 as fall refuelling passes its peak

US nuclear capacity offline fell to 16,008 megawatts (MW) on Nov 12, from a peak of 20,248 MW on Nov 4. More reactors coming back from fall refuelling should mean somewhat less gas burned for power.

About 4.2 gigawatts of nuclear capacity came back in one week

The Energy Information Administration (EIA) publishes daily nuclear capacity outage figures. They show how much US reactor generating capacity is offline each day. When reactors are offline, other power plants, such as gas plants, have to make up the difference.

  • Nov 4: 20,248 megawatts (MW) offline, the peak
  • Nov 7: 19,297 MW offline
  • Nov 12: 16,008 MW offline

About 4.2 gigawatts (GW) returned over the past week. Total US nuclear capacity was unchanged at 100,057 MW. Roughly 84% of the fleet is now available.

Outages are still high compared with the summer

Outages fell to a low of about 1,000 MW in late July. They rose through September and October as plants shut down for fall refuelling. That refuelling season now looks past its peak.

Palisades in Michigan is still completely offline

The Palisades plant is listed as fully out of service. On each of the past 40 days, its outage has equalled its full capacity of 815.6 MW.

Electricity demand was normal for mid-November

Hourly electricity demand in the Lower 48 states, meaning the contiguous United States, peaked near 493k megawatthours (MWh). That peak came at the start of Nov 12 in Coordinated Universal Time (UTC). On Nov 11 the peak was about 490k MWh.

About FactIQ and these updates

  • What FactIQ is. FactIQ is a database of official statistics from government agencies, central banks and international organisations in the US, China, India, Europe and elsewhere. AI assistants such as Claude and ChatGPT connect to it to look up the exact figures and cite the agency that published them. It also holds what companies report in their filings and say on their earnings calls.
  • How an update is made. When Energy Information Administration publishes new figures, FactIQ loads them and an AI model writes a short summary of what changed. Before it is published, code checks that every number in the summary matches FactIQ's record of the release, and a second review checks that nothing is overstated. Values that look like errors in the source data are left out.
  • Where the numbers come from. Each key figure links to the full series, with its source, units and history.
