A regional first: New Englanders used less grid electricity midday than while they were sleeping on April 21

May 3, 2018

On Saturday, April 21, 2018, the right combination of sunshine and mild weather led to light consumer demand on the high-voltage electric power system, coupled with record-high output from the more than 130,000 solar power installations in the region.
