TL;DR: A U.S. Department of Energy emergency order effective Oct. 13-16 gave grid operator PJM extra tools to prevent outages during October heat and fall maintenance — no blackouts are expected and customers were not asked to take action.

What happened on Oct. 13

The U.S. Department of Energy issued an emergency order effective Oct. 13-16 covering 13 states and Washington, D.C., according to WUSA9 reporting published Oct. 13, 2026.

The directive was signed by Energy Secretary Chris Wright and directed at PJM Interconnection, the organization that coordinates electricity transmission across the District region and much of the Mid-Atlantic.

Federal officials framed the move as preventive. Wright said in a statement that the order would help ensure families and businesses across the Mid-Atlantic have access to affordable, reliable and secure electricity by making additional power generation, including backup power, available as needed.

The order did not forecast blackouts or brownouts. It was intended to lower the risk of outages while the system operated under stress.

The action followed a PJM alert for Oct. 13. That alert allowed transmission and generation owners to delay or cancel equipment maintenance or testing, and PJM said the notice required no customer action.

Why heat and maintenance collided

The core problem was timing. Unseasonably warm autumn weather lifted electricity demand at the same moment power plants and transmission equipment were offline for planned fall work.

PJM routinely schedules maintenance during cooler fall months when demand is lower. This year, that seasonal window did not appear.

Temperatures during the week of the order ran 10-20 degrees above normal across PJM territory, Dominion Energy spokesperson Jeremy Slayton told Axios Washington D.C. in Oct. 14 reporting.

The District area was described as moving through near-record October heat while the Mid-Atlantic grid entered the emergency period.

That combination left fewer mild-weather days to service generation and transmission equipment serving the PJM footprint.

Who PJM is and who is covered

PJM Interconnection manages electricity flows across more than 67 million people in 13 states plus the District, according to Maryland Patch reporting on the order.

The federal order identified three utility areas as facing especially acute challenges: Pepco, Dominion Energy, and Baltimore Gas and Electric, according to Axios Washington D.C.

Pepco serves customers in Washington and Maryland. Dominion serves much of Loudoun County, including the corridor often called Data Center Alley. Baltimore Gas and Electric serves the Baltimore region.

Dominion told Axios that none of the data centers it serves had been switched to backup generators because of the order.

The order remained in effect through Friday, Oct. 16, although PJM said additional measures could be necessary depending on grid conditions.

What extra tools the order unlocked

The emergency authorization gave PJM additional ways to keep electricity flowing through the week.

It allowed PJM to tap additional power generation and, under defined conditions, temporarily exceed certain environmental permit restrictions, according to Axios Washington D.C.

As a last resort, the order allowed PJM to direct data centers and other major electricity users to operate on backup generators rather than drawing from the grid.

WTOP News reporting on Oct. 15, 2026, described the same backup-generator provision as a step to be used before customer outages would be considered.

Federal officials also pointed to national reserves. The Department of Energy said 35 gigawatts of unused backup generation remained available nationwide if needed, according to Maryland Patch.

PJM separately extended operating alerts through Wednesday of that week, warning power suppliers that conditions were tight.

What customers were told to do — and not do

For households in the District, Maryland and Virginia, the immediate message was simple: no action was required.

PJM said its Oct. 13 alert required no customer response. Both WUSA9 and Axios reported that customers were not being asked to conserve energy at that stage.

If electricity demand began to outpace available supply, customers could later be asked to voluntarily reduce power use. Residents were advised to monitor updates from their electric utility and local officials in case conditions changed.

Social media complicated that message. The federal order circulated online, where some users incorrectly suggested a major blackout was imminent, according to WUSA9.

Some posts urged people to stockpile water and nonperishable food or warned that widespread outages were coming. Grid officials did not issue those warnings.

The confirmed guidance was narrower: stay informed, watch utility channels, and wait for any formal conservation request.

Why officials call this a new pattern

PJM and outside analysts said October conditions reflected broader pressure on the Eastern grid.

A PJM spokesperson said increased electricity demand, slower growth in generation capacity and unpredictable weather were creating new challenges for grid operators.

In a statement provided to multiple outlets, PJM said conditions in September and October showed that increased baseload demand was growing faster than new capacity could enter service, while unpredictable weather left fewer days for maintenance or construction.

PJM said planned maintenance outages were increasingly becoming a reliability concern outside the traditional summer and winter peak seasons.

PJM spokesperson Jeff Shields told Axios, “This is the new reality that grid operators are facing,” pointing to fewer stretches of mild weather for essential maintenance.

Shields added that planned maintenance season would continue to present risks formerly seen only in summer and winter.

Pepco spokesperson Chuck McDade told Axios that growing demand from data centers, electric vehicles and other sources was adding pressure as older power plants retire.

Ali Mehrizi-Sani, director of Virginia Tech’s Power and Energy Center, told WTOP News that rapid demand growth was part of the issue and that warnings once considered rare were being issued more frequently.

September warning signs

The October order was not the first fall reliability action.

Sweltering heat had previously forced PJM to act in mid-September, according to Maryland Patch.

PJM flagged two earlier periods — Aug. 31 to Sept. 4 and Sept. 15-18 — when it had to balance reliability against planned transmission and generation limitations as well as exports to neighboring systems.

On Sept. 17, PJM recorded a system peak shortly before 5 p.m., with system outages of 20.7% occurring the next day.

Mehrizi-Sani told WTOP News that Northern Virginia in particular had seen larger-scale electrification, leaving the system operating closer to its limits.

He said more investment and hardening of the power system would be needed, adding, “We need to have more generation and more transmission to be able to deal with the rapid load growth that we are experiencing.”

The October emergency therefore fit a short-term pattern of heat arriving during maintenance season, layered over longer-term load growth.

Household readiness while no outage is expected

Emergency guidance distinguished between the federal grid order and personal preparedness. Households were not told to expect an outage, but utilities offered practical steps for heat and high bills.

Axios reported utility suggestions to raise thermostats 3-4 degrees, use ceiling fans, close blinds and shutters, and run dishwashers and washing machines after dark.

Those steps were presented as ways to save money during unusual October heat, not as emergency orders.

Electricity supply costs were already climbing as regional demand outpaced available power. A typical Pepco customer in Washington was paying about $30 more per month for electricity supply than in 2024, while Maryland customers were paying roughly $17 more, according to the utility as reported by Axios.

Pepco said those increases were not a direct result of the week’s emergency, but said the same supply pressures were driving costs higher.

Residents who rely on powered medical devices, elevators, or refrigerated medication should keep their normal backup plans current and contact their utility about medical-priority lists. That is general household practice, not a directive issued in the October order.

How to follow official updates

Because conditions could shift, officials asked residents to use utility and government channels rather than social-media rumors.

Customers can check their own utility — including Pepco, Dominion Energy, and Baltimore Gas and Electric — for outage maps, alert sign-ups, and any voluntary conservation request.

PJM posts operating alerts and system information for its footprint. The Department of Energy posts emergency orders and statements from the secretary.

Local emergency-management offices in the District, Maryland counties, and Northern Virginia cities also relay utility guidance during grid events.

If PJM or a utility asks for voluntary reduction, that request will come through those official channels. Until then, officials said normal use could continue while the preventive federal order remained in place through Oct. 16.
