Largest US power grid PJM escalates emergency actions to avoid blackouts

Source: Reuters

July 3, 2026 2:46 PM EDT Updated 36 mins ago


July 3 (Reuters) - Largest ​U.S. power grid operator PJM said ‌on Friday it was under a federal alert to cut electricity consumption across its ​territory as it battled generator outages, ​massive overloading on its transmission lines ⁠and a surge in air conditioning ​use from prolonged sweltering heat.

PJM said it ​told utilities to reduce electricity to customers who are under contract to reduce consumption during ​emergencies.

PJM serves 67 million people ​in the Mid-Atlantic, South and Washington, D.C., area.

Spot ‌wholesale ⁠electricity prices in northern Virginia, home to the largest collection of data centers in the world, have surged beyond $2,000 ​per megawatt ​hour this ⁠week. That compares to about $40 per MWh when PJM ​is not in distress.

Its a serious disease in this country. Everything is lit - every shelf in the store, every sign above businesses that are closed, lights everywhere. Entire buildings lit up with decorative lights. Offices lit all night for no reason. Its psychotic. Meanwhile the grid is being overwhelmed.

is that most of that lighting is LED, which uses much LESS energy and provides more bang for the buck.

has no lights on shelves and the frozen section freezer lights only turn on when a person is next to that segment of freezer space.
The smaller market that is closer to me leaves the freezer lights on but don't have more lights than they did decades ago. Lights are not the problem with electric use, blackouts and brownouts happen during the day when electricity use is the highest.

watt hours are watt hours, every single one counts at this point, all down the line. Thats why social fads like extreme lighting are so bad - everybody has to prove themselves and it becomes a major load on the sytem. Its also the sheer arrogance of lighting each bottle of wine.

3. From Capacity to Chaos: How AI Data Centers Challenge the Grid
Fri Jul 3, 2026, 04:14 PM
20 hrs ago

Data centers are an f-ing nightmare

To protect the American people from the countless harms, a national moratorium until the problems can be addressed should be a priority for electeds and candidates.

https://www.datacenterknowledge.com/uptime/from-capacity-to-chaos-how-ai-data-centers-challenge-the-grid

AI data centers are challenging a core assumption about the grid: that large loads operate predictably. The issue is not only how much electricity these facilities require, but also how they behave during disturbances.

This risk became reality in 2024, when dozens of data centers in Northern Virginia dropped off the grid in a single event, instantly removing roughly 1,500 MW of load, according to Reuters.

In this instance, grid operators moved quickly to stabilize the system and avoid broader outages. However, regulators have warned that the grid is not designed to withstand the sudden loss of such large blocks of demand.

The US is experiencing its fastest sustained growth in electricity demand in decades, with the Energy Information Administration projecting annual increases of roughly 2% through 2027, largely driven by data centers.

In regions like PJM, load forecasts show a sharp rise in peak demand with data centers accounting for a significant share of new load, while the Electric Reliability Council of Texas (ERCOT) has reported rapid growth in large-load interconnection requests tied to data center development.

Together, those trends point to a system under new strain – not just from the amount of power required, but also from how quickly large loads can change.

From Steady Load to Sudden Swings

over every inch of their roofs and parking areas. These would provide power for the servers and electricity for cooling systems.

Any excess power they generate could be channeled back to the utility grid during peak cooling times.

Covering their parking lots and roofs with solar panels would offset a few MINUTES of their daily consumption. They're truly energy hogs of the highest order.

Fri Jul 3, 2026, 05:56 PM

The amount of power required is utterly mind-boggling -- 50 to 100 megawatts and more -- which is what the essential problem is.

It would take over 1000 acres of panels. The roof wouldn't offer much space because they need to be covered with cooling equipment.

There are discussions of combined wind / solar / battery storage:
https://www.techtarget.com/searchdatacenter/tip/How-to-use-data-center-wind-turbines-for-sustainable-energy

The thing is, it is insane for this nation to be pushing forward with these monsters until approaches that don't cause the incredible harms are designed and regulated. Really and truly insane given that it is all for a technology that is costing billions for failure after failure to provide ROI. Talk about an f-ing money pit. Absolute lunacy.

Maybe they should use AI to solve this problem before building more centers.
I imagine the first part of the solution would be to eliminate Republicans that are blocking renewable sustainable energy.

Yes, that seriously needs to happen.

The proliferation of these energy hog data centers should not be allowed to continue willy-nilly. It's a disaster waiting to happen, and it's one that is completely foreseeable. We need some adults in the freaking room to put ths brakes on before the worst happens.

You know, the career public servants, who watch the nitty-gritty details of your daily lives, making life bearable, like keeping the lights on, keeping water and sewage at your place flowing, etc?

What do they think of data centres?

If those go unrestricted, we are heading for a dystopian future.

Sitting in your cold living room in winter, with only a candle for light, while the data center next door is humming and bathed in lights everywhere.
And in summer? No AC, just cold showers every 30 minutes and sitting in front of a fan.

Welcome to the future!

With more power plants. What is really needed are cooling systems that are more efficient. Cooling using less energy. It's only going to be worse in years to come, should be working on ways to alleviate the problem.

37. What needs replacing is private equity monopolizing utilities
Sat Jul 4, 2026, 03:45 AM
9 hrs ago

Private equity (PE) firms are aggressively acquiring regulated public utilities, a trend heavily driven by the artificial intelligence (AI) data center boom and the stable, guaranteed rates of return these essential services offer. When a PE firm takes a utility private, it introduces an aggressive, profit-maximizing corporate structure to a captive customer base.

The standard PE timeline relies on holding an asset for a few years while cutting operational overhead to maximize short-term cash flow, then flipping it for a profit. This can lead to severe underinvestment in long-term safety, maintenance, and upkeep, increasing the risk of infrastructure failures.

When a PE firm takes a utility private, it introduces an aggressive, profit-maximizing corporate structure to a captive customer base. PE firms frequently fund acquisitions by saddling the target utility company with immense amounts of debt. Captive ratepayers end up with the bill, paying higher rates just to service the Wall Street debt used to buy the utility in the first place.
