The United States has issued an emergency power grid order covering parts of 13 states and Washington, DC, as federal authorities move to prevent electricity shortages and possible blackouts amid rising demand and disruptions caused by scheduled maintenance.
US Energy Secretary Chris Wright issued the directive on October 12, authorising PJM Interconnection, one of the country's largest regional electricity grid operators, to deploy additional generation capacity and activate backup power resources when necessary.
The emergency order, effective from October 13 to October 16, is intended to maintain electricity supplies across the Mid-Atlantic and Midwest regions during a period of unusually high demand and reduced availability of generation and transmission infrastructure.
Officials clarified that the declaration was a preventive measure and did not mean that scheduled blackouts had been announced.

The US Department of Energy issued the order under Section 202(c) of the Federal Power Act following an application submitted by PJM Interconnection on October 11.
The directive authorises the grid operator to instruct designated power generation facilities to operate when required to maintain system reliability.
It also permits PJM to call upon backup electricity generation resources as a last resort before declaring the most severe level of energy emergency, known as Energy Emergency Alert 3, or during such an alert.
The Department of Energy said the measures would make additional electricity generation available to support millions of households and businesses dependent on the regional grid.
Wright said the order was intended to ensure access to reliable electricity by making additional power generation, including backup supplies, available when necessary.

PJM Interconnection coordinates wholesale electricity movement across all or parts of 13 states and the District of Columbia.
The states covered by its service territory are Delaware, Illinois, Indiana, Kentucky, Maryland, Michigan, New Jersey, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia and West Virginia.
The emergency directive applies to the PJM grid network rather than automatically placing every household in these states under electricity restrictions.
PJM is responsible for balancing electricity generation and consumption while ensuring that power can be transmitted safely across its interconnected network.
The operator serves a vast region containing major cities, industrial facilities, commercial establishments and large data centres, making grid stability important for both households and economic activity.

The emergency measures follow forecasts of unusually warm autumn weather, which are expected to increase electricity consumption across the PJM region.
Electricity demand was projected to reach approximately 111,500 megawatts or more on October 13, adding pressure to a system already affected by scheduled maintenance.
The autumn maintenance season typically extends from mid-September to early December, when electricity companies temporarily take generating units and transmission infrastructure out of service to carry out repairs and upgrades before winter.
This year, the combination of elevated demand, planned generator outages and transmission restrictions has raised concerns about the availability of sufficient electricity.
PJM issued a Maximum Generation Alert and a Load Management Alert for October 13 to prepare for the anticipated strain.
The Department of Energy warned that without additional emergency measures, the grid operator could face conditions requiring electricity demand to be reduced to preserve overall system stability.

A significant feature of the emergency directive is the provision allowing PJM to access backup generation resources at large electricity-consuming facilities.
These include data centres, major industrial installations and commercial establishments equipped with standby generators, battery storage systems or other independent power sources.
The authorities are exploring whether such facilities can temporarily operate their backup systems to reduce pressure on the regional electricity network.
The measure could help free up electricity for other consumers during periods when demand approaches available generation capacity.
The Department of Energy has estimated that more than 35 gigawatts of unused backup generation capacity is available across the United States, although not all of it is necessarily accessible within the affected region.
Backup generation under the emergency order is intended as a last-resort measure rather than a routine replacement for conventional electricity supplies.

For households across the affected region, the emergency declaration does not automatically require changes in electricity consumption or indicate that power cuts are imminent.
Residents can continue using electricity normally unless local utilities or grid authorities issue specific conservation requests or restrictions.
However, if demand rises beyond expectations or available generation declines further, PJM may ask businesses and households to voluntarily reduce non-essential electricity use during peak periods.
Such measures could include limiting unnecessary lighting, reducing electricity consumption from high-demand appliances and adjusting cooling systems where practical.
In more serious circumstances, grid operators have procedures for controlled reductions in electricity supply to prevent widespread system failures. No such general household blackout schedule has been announced under the current order.
The emergency framework follows established North American electricity reliability standards, which provide procedures for responding to capacity shortages, extreme weather and other threats to grid stability.

The emergency authorisation will remain effective through October 16, giving PJM temporary flexibility to deploy generation resources and manage electricity supplies during the anticipated period of heightened pressure.
Federal authorities said the objective was to prevent a deterioration in grid conditions that could otherwise lead to more severe emergency interventions.
The situation also highlights the growing challenge facing US electricity networks as demand from households, industries and energy-intensive data centres increases while ageing infrastructure requires regular maintenance.
For now, the emergency order is aimed at preventing outages rather than responding to a widespread blackout, with authorities continuing to monitor demand, generation availability and transmission conditions across the 13-state network.
The central challenge for grid operators will be maintaining sufficient electricity supplies while ensuring that the emergency measures can be withdrawn once normal operating conditions return.
