New England – Mt Washington – set a record of 65 degrees recently. And while 65 degrees may not seem particularly warm, back in January Mt Washington was the second coldest place on the planet.
With all that, this summer has been a hot one in which grids in several parts of the nation have leaned heavily on solar power. We saw hints of this coming back in the cool spring days of April when it became clear that New England had developed a case of the duck curves, with solar meeting 20% of demand and pushing peak pricing to after sundown. On July 19 solar provided as much as 15% of total electricity in New England, knocking a full 2 GW off of demand at its peak and shifting that peak to the early evening.
