The U.S. Energy Information Administration (EIA) expects nearly 32 gigawatts (GW) of new electric generating capacity will come online in the U.S. in 2018, more than in any year over the past decade. Although renewables accounted for 98% of the 2 GW added so far this year (based on data for January and February), EIA expects about 21 GW of natural gas-fired generators will come online in 2018. If these generators come online based on their reported timelines, 2018 will be the first year since 2013 in which renewables did not make up a majority of added capacity.
The newly added generating capacity in January and February 2018 included 2,029 megawatts (MW) of renewables, 27 MW of fossil fueled generators, and 28 MW of other technologies, mostly consisting of energy storage batteries. In February 2018, for the first time in decades, all of the new generating capacity coming online within a month were non-fossil-fueled.
