In our Summer Electricity Outlook, a supplement to our May 2022 Short-Term Energy Outlook, we expect the largest increases in U.S. electric power sector generation this summer will come from renewable energy sources. These increases are the result of new capacity additions. We forecast utility-scale solar generation between June and August 2022 will grow by 10 million megawatthours (MWh) compared with the same period last summer, and wind generation will grow by 8 million MWh. Forecast generation from coal and natural gas declines by 26 million MWh this summer, although natural gas generation could increase in some electricity markets where coal supplies are constrained.
