NE power grid demand falls to its lowest level ever
Part of shift caused by solar power on homes
DEMAND FOR ELECTRICITY from the New England power grid fell to an all-time low on Sunday, a reflection of the weather and the region’s embrace of solar power.
Sunday was a very pleasant day, with mild temperatures, sunshine, and Sunday’s relatively low demand for electricity. The combination meant homeowners didn’t need heat or air conditioning, and the sunshine allowed homeowners with solar panels to generate more than 4,000 megawatts of power on their own.
Overall, demand for power from the grid fell to 7,580 megawatts during the afternoon, the lowest level since ISO-New England began operating the grid in 1997.Five years ago, on Sunday May 6, 2017, power demand from the grid was 10,929 megawatts.
The first time demand for power from the grid was lower in the afternoon than at night was on April 21, 2018. It happened 35 more times through the end of 2021 and it has happened 29 times so far this year.
