Regional transmission organization PJM Interconnection said Wednesday has issued widespread emergency alerts and secured federal orders to maintain power generation as extreme heat and humidity push electricity demand past an all-time summer record high of 165,563 megawatts.
A regional Hot Weather Alert will stay active for the entire PJM territory until at least Friday to prepare energy plants and transmission teams for massive spikes in power usage, the operator said on Wednesday.
Additionally, Maximum Generation and Load Management Alerts have been extended through Thursday, PJM added.
The power grid is bracing for massive stress as electricity demand is projected to approach, and potentially smash, historical records.
On Tuesday, the grid handled a preliminary peak load of around 150,000 MW. However, current projections show demand climbing rapidly over the week, with an expected peak of 166,147 MW for Thursday, it said.
If demand hits the forecast, it will break PJM's all-time summer electricity record of 165,563 MW in 2006, PJM stated.
Demand is expected to taper off slightly over the holiday weekend, dropping to 157,878 MW on Friday, 150,069 MW on Saturday, and 142,913 MW on Sunday, it noted.
PJM has also secured two federal emergency orders from the US Department of Energy.
The first order grants power plants temporary relief from strict environmental permit limits so they can run at maximum capacity through July 3.
The second order gives PJM the authority, as a strict last resort before facing blackouts, to temporarily cut grid power to data centers and other massive commercial loads that can successfully switch to using their own backup generators.
