Twice so far in 2021, Governor Newsom has suspended *all* environmental regulations on CA electricity generators for at least three days at a time.
On each of June 17 and July 9, the Governor issued State of Emergency proclamations covering separate “Extreme Heat Events” lasting several days. During each Extreme Heat Event, “[a]ny permit, regulation or law prohibiting, restricting or penalizing the use of stationary or portable [electricity] generators” was suspended, due to “significant demand and strain on California’s energy grid,” according to each proclamation.
