Last week, West Virginia Metro News’s T. J. Meadows reported that PJM Interconnection had undertaken a preload emergency management reduction action across its system. This measure came in response to the Independence Day Week heat wave that has settled in the Eastern United States.
It also released a Maximum Generation Alert for July 3.
That said, the organization also stated that “this alert does not require any action from customers.”
PJM Interconnection, according to the Federal Energy Regulatory Commission, “operates a competitive wholesale energy market and manages the reliability of its transmission grid.” That grid serves the Mid Atlantic and part of the Midwest into the Chicago area.
Its main pillars of energy production rest on facilities in Pennsylvania and West Virginia. Its job lies in both ensuring the reliability of electric power while trying to keep consumer costs as low as possible. They do this through promoting grid capacity by encouraging adding supply to meet demand and also for added transmission lines to carry the increasing burden of national power demands.
West Virginia Governor Patrick Morrissey along with the West Virginia State Legislature have enacted policies to help PJM Interconnection meet rising demand in its area covering 13 states and the District of Columbia. This has helped PJM consumers avoid some of the problems afflicting other parts of the nation.
New York State, which uses its own system, called for voluntary load management from its system customers last week, asking them to keep thermostats in the high 70s to prevent power disruption. The Empire State has embraced “Green” policies over the past several years that block relatively inexpensive Appalachian natural gas from power production and also closed the Indian Point nuclear power plant that once supplied 25 percent of New York City’s power.
Reducing the supply of power for that system has forced New Yorkers to deal with the consequences of those policies. Also, since it is in a different system, its dysfunction does not affect PJM Interconnection’s system. Should PJM Interconnection’s ability to supply power fail to keep up with demand due to too little electricity generated by power plants, its average consumers could face similar issues as New Yorkers have so far this month.
PJM Interconnection advocates for policies at the state and federal level that will keep consumer rates as low as possible in the long-term as well. This includes advocating for policies that data center operations not pass on the added cost of their power to residential or other business customers. The West Virginia State Legislature, for example, followed this lead and mandated that data centers pay for their own electrical upgrades while also encouraging them to develop “microgrids,” independent sources of power that do not draw from the grid. Nor could they sell power to others to compete with the grid.
A preload emergency management reduction represents an early step in response to spikes in demand. One could consider electric power almost like a financial budget in this sense. PJM Interconnection has agreements in place with certain consumers to reduce use in ways that will not affect the average consumer. The purpose lies in keeping rates flat while also ensuring a steady flow of power.
One could consider it the same as reducing the weekly eating out at a restaurant part of the budget to help pay for an unexpected car repair. The budget remains in good shape, but requires moving resources around.
According to PJM Interconnection, it works because their “Demand Response programs pay customers in advance who sign up to allow reduction of their electricity use in emergencies.”
PJM Interconnected had to take these steps in June of 2025. In the wake of power demand hitting its highest level since 2011 last year, the organization released details. It stated that “PJM served a preliminary hourly integrated peak load of 160,526 MW between 5 and 6 p.m. Eastern on June 23. This exceeds PJM’s summer forecast load of 154,000 MW and is the highest demand recorded on the PJM system since 2011.”
One megawatt powers approximately 800 homes.
In addition to the pre load emergency reduction action, it also declared a maximum generation alert.
Last Thursday, PJM Interconnection reported that “its peak instantaneous load was approximately 162,700 MW between 5 and 6 p.m., according to preliminary figures, but that figure was suppressed by the use of demand response programs. The peak load is likely to have surpassed the all-time PJM record of 165,600 MW set in 2006.”
It explained also that “PJM coordinates with its generation and transmission owners as we respond to the needs of the grid in real-time based on actual conditions to preserve reliability for the 67 million people we serve.”
The Maximum Generation Alert, explains PJM Interconnection “is targeted at transmission/generation owners, who then determine if any maintenance or testing on equipment can be deferred or canceled. By deferring maintenance, the units stay online and continue to produce energy that is needed to serve electricity demand within the PJM region.”
Relief came last weekend as rains returned to the region, ushering in somewhat lower temperatures.
