Projected electric capacity additions are below recent historical levels

In the coming decades, additions to U.S. electricity generation capacity are expected to be lower than in the recent past. In EIA's Annual Energy Outlook 2015 Reference case, which reflects current laws and policies and does not include EIA's proposed Clean Power Plan, total generating capacity (including end-use generators like rooftop solar panels) increases from 1,065 gigawatts (GW) in 2013 to 1,261 GW in 2040.
