When conditions are right, the ISO sees a significant reduction in regional electricity demand from behind-the-meter (BTM) solar photovoltaic (PV) installations. During a heatwave in July 2018, BTM solar generation peaked each day at around 1:00 p.m., reducing demand from the regional power system by approximately 2,000 MW. [vermontbiz.com]
On a cool, sunny day in April 2018, BTM solar output reached an estimated record high at 1:00 p.m. and drove down electricity demand on the regional power system by 2,300 MW. The result was a regional first: New Englanders used more grid electricity while they slept that night than during the middle of the day. [vermontbiz.com]
Total wind generation share in 2018 for ISO-NE was 3%. [AWEA Blog]
