The U.S. Energy Information Administration (EIA) collects data on whether an electric generator is owned by one company or jointly owned by several companies, and for those jointly owned, each owner’s share of ownership. In 2019, about 14% of the 1,099 gigawatts (GW) of total operational U.S. electricity generating capacity was jointly owned. Nuclear capacity had the highest percentage of joint ownership at 37%, followed by pumped-storage hydropower at 34% and coal at 29%. These types of power plants tend to be large-scale facilities that are expensive to build, and the technologies come with higher regulatory risks, making joint ownership more attractive by reducing plant ownership risks for each owner.
