Recent business shutdowns and changes to normal routines related to mitigation efforts for the 2019 novel coronavirus disease (COVID-19) have caused daily, weekday electricity demand in New York state to decrease by 11%–14% in March and April compared with expected demand, after accounting for seasonal temperature changes. Electricity demand changes in New York state and in New York City, in particular, have been more pronounced than in other parts of the country, which may partly be caused by differences in electricity consumption across regions and the varying effects of COVID-19 mitigation efforts on these sectors.
