This alert was issued in anticipation of tight conditions on the 13-state system as electricity demand is set to top 160 gigawatts on the afternoon of June 23, which would be the highest peak since July 2011, according to PJM. The Eastern US grid operator also called a “maximum generation emergency” to shore up supplies.
