U.S. net electricity generation increased by 4% in 2018, reaching a record high of 4,178 million megawatthours (MWh), according to EIA’s Electric Power Monthly. Last year was the first time total utility-scale generation surpassed the pre-recession peak of 4,157 million MWh set in 2007. Weather is the primary driver of year-to-year fluctuations in electricity demand. The increased demand for electricity in 2018—including record demand in the commercial and residential sectors—is largely attributable to cold winters and a hot summer.
