NEW UPDATE — WEDNESDAY, OCT. 14, 5:45 P.M. EDT: PJM Interconnection now expects emergency system conditions to ease after Wednesday. In Emergency Message 105573, issued at 5:45 p.m., the grid operator said it has not identified a reliability need to use the generating resources specified in federal Emergency Order No. 202-26-50 on the Oct. 15 and Oct. 16 operating days. “Emergency system conditions are not expected to continue past 10/14,” PJM stated.
What has changed: This is a new PJM forecast that the emergency measures may no longer be needed after tonight, not an announcement that the federal order has been canceled. The order remains scheduled to expire Oct. 16. The specified resources include four FirstEnergy Lemoyne generating units in Wood County, Ohio. PJM’s notice does not establish whether those units operated under emissions-limit relief on Oct. 13 or Oct. 14; that remains a question for DOE’s daily reliance reporting.
Alert status: The reviewed PJM dashboard still lists EEA 1 through 11:59 p.m. EDT Oct. 14, with no EEA 2, EEA 3 or controlled Ohio blackouts established by the posted messages. Primary source: PJM Emergency Procedures, Message 105573 (5:45 p.m. EDT). DOE Emergency Order 202-26-50 and related filings.
LATEST UPDATE — WEDNESDAY, OCT. 14, 5:20 P.M. EDT: PJM posted an additional transmission-related warning at 4:56 p.m. EDT, Emergency Message 105572, identifying a post-contingency loading concern on the Dillsburg–Gardners transmission facility and a 124-MVA operating limit. The warning lists BGE, FirstEnergy Met-Ed, PECO and PPL utility zones; PJM noted a slow generation response. The warning follows a 4 p.m. 30-minute demand-response activation in BGE, Dominion and Pepco zones, and the broader 2 p.m. activation covering 18 utility zones, including Ohio’s AEP, Dayton, Duke Energy Ohio/Kentucky and FirstEnergy ATSI territories.
Emergency classification: PJM’s posted systemwide designation remains Energy Emergency Alert Level 1 (EEA 1). These notices do not establish EEA 2, EEA 3, a directive for residential rolling blackouts or a confirmed Ohio power interruption. The demand-response actions are mandatory for dispatched enrolled participating resources, not a blanket order for Ohio households. Read PJM’s emergency postings (Messages 105568–105572 and 105563).
OFFICIAL PDF DOCUMENT: Read the U.S. Department of Energy’s original Emergency Order No. 202-26-50 (11-page PDF). Issued Oct. 12 and effective Oct. 13–16, this order authorizes specified emergency generation measures. It is the legal order underlying the response, not a report confirming that any particular Ohio plant used an emissions-limit waiver. DOE docket and updated resource exhibits.
NEW UPDATE — WEDNESDAY, OCT. 14, 4:00 P.M. EDT: PJM Interconnection activated an additional, faster 30-minute demand-response program in the Baltimore Gas and Electric (BGE), Dominion (DOM) and Pepco (PEPCO) utility zones, according to Emergency Message 105571. Participating resources must reduce electricity use under the program until PJM releases them. The new action follows the 2 p.m. activation of longer-duration demand-response resources across 18 zones, including AEP Ohio, Dayton, Duke Energy Ohio/Kentucky and FirstEnergy ATSI.
At 3:29 p.m., PJM also posted a separate transmission load-relief warning for the Ashburn–Goose Creek corridor in Dominion’s Virginia territory, citing a 1,579-MVA transmission limit (Message 105570). PJM’s published systemwide alert for Wednesday remains at Energy Emergency Alert Level 1. Neither the new demand-response activation nor the transmission warning establishes that PJM ordered rolling blackouts or declared EEA 2 or EEA 3.

BREAKING UPDATE — WEDNESDAY, OCT. 14, 2:00 P.M. EDT: PJM Interconnection activated another round of pre-emergency electricity demand reductions, issuing Emergency Message 105568 across 18 utility zones, including AEP Ohio, Dayton, Duke Energy Ohio/Kentucky and FirstEnergy’s ATSI territory. The action dispatches enrolled 60-minute and 120-minute demand-response resources, which must reduce electricity use until released by PJM. It does not direct all Ohio households to reduce their electricity use.
At 2:01 p.m., PJM also issued a separate transmission load-relief warning for the Pleasant View–Ashburn corridor in Virginia. The grid operator’s Energy Emergency Alert Level 1 remains in effect for Wednesday; these notices do not constitute an EEA 2 or EEA 3 declaration.

LATEST, WEDNESDAY, OCT. 14 — PJM Interconnection has extended its Maximum Generation Alert into Wednesday evening, with another round of demand response expected to be called for the evening peak, as generation outages climbed nearly 2 gigawatts day over day and the grid operator braced for system-wide load to rise by more than 5 gigawatts. Heat is concentrated in the eastern part of the footprint — feels-like temperatures pushing back into the 90s across Dominion Energy’s Virginia territory — while load in the South approaches 21 gigawatts, driving an extreme day-ahead result in that zone.
The squeeze has already reached Ohio customers. On Tuesday afternoon, PJM issued a Pre-Emergency Load Management Reduction Action for its long- and short-duration demand-response resources across a long list of zones that includes AEP Ohio, FirstEnergy’s ATSI system, Dayton and Duke Energy Ohio/Kentucky — the step that calls on enrolled homes and businesses to cut electricity use. Five-minute system load pushed past 101 gigawatts that afternoon, against more than 60 gigawatts of generation out of service in the heart of outage season.
PJM still expects to remain a net exporter over tonight’s peak, though peak flows are set to drop day over day, with imports from New York’s grid scheduled to rise and milder conditions across the Midwest’s MISO footprint easing some of the pressure. The federal emergency order behind the response — U.S. Department of Energy Order No. 202-26-50 — remains in effect through Friday, Oct. 16.
The numbers behind the request show how close the grid ran to the edge. PJM told the Energy Department it expected roughly 61,591 megawatts of generation to be out of service — planned, maintenance and forced outages combined — against a forecast peak load of about 111,500 megawatts for Oct. 13, a forecast PJM later updated to 112,447 megawatts. For Oct. 14, PJM projected its reserve margin could come within about 900 megawatts of the line — a sliver for a system of this size.
What the order actually does is loosen the pollution rules for a short list of plants, for four days, under certain conditions. Specified generating units may operate beyond their environmental permit and rolling-average limits while the order is in effect. It is not a blanket suspension of environmental law: the order requires monitoring, reporting and limits on operating hours to the maximum extent practicable, excludes critical facilities, and expires Oct. 16. PJM must identify, in daily notifications to the Energy Department, which units actually operated in reliance on the order.
Ohio plants are on that list. PJM’s updated Exhibit A, filed at 5:17 p.m. on Oct. 12, names four FirstEnergy Lemoyne units at Luckey, in Wood County, among the resources potentially covered — flagging them for nitrogen-oxide rolling limits, the kind of Ohio permit restriction a federal emergency order can temporarily override. Inclusion on the list does not by itself prove any unit ran over its limits; that is what the daily reliance reports are for.
Ohio customers felt the edges of the emergency in quieter ways. PJM issued a Maximum Generation Alert for Oct. 13 and a Capacity Advisory extending through Oct. 14, declared an Energy Emergency Alert Level 1 on Oct. 13, and posted pre-emergency demand-response activation notices that afternoon — the step that puts large power users on notice to cut load before the grid reaches controlled outages. PJM said the alert by itself required no action by customers. Nothing in PJM’s postings indicates the grid reached EEA 3, its most serious alert level, and the existence of the order does not mean widespread blackouts occurred.
The order also arms a last resort with an Ohio address. Before declaring an EEA 3, or during one, PJM may direct backup generation resources to operate in support of the grid — the generators standing behind large loads, including Ohio’s growing fleet of data centers. The Energy Department describes that authority as a last resort, and there is no indication any Ohio facility was ordered onto backup power this week.
What it means for Ohio is threefold. First, the squeeze is no longer seasonal: a mild-weather shoulder month produced a federal emergency order, with winter still ahead. Second, when the grid needs a relief valve, Ohio is part of it — Ohio plants, Ohio permits and Ohio air are in the mechanism, with the state’s own nitrogen-oxide limits temporarily overridden by Washington. Third, reliability held — but it held with the emergency playbook open: maximum generation alerts, demand-response notices, and a federal waiver standing behind them.
The order expires Oct. 16, and whether it is extended — and what the reliance reports show — is now the story. J News Network is seeking PJM’s day-by-day notifications to the Energy Department identifying which units and backup resources actually ran under the order, Ohio EPA records on the Lemoyne units’ nitrogen-oxide limits and any emergency operating reports, and the Energy Department’s after-action and environmental compliance reporting. Until those records are public, the central fact stands: for four days in October, keeping the lights on in Ohio required the federal government to loosen the pollution rules — and even then, the margin was measured in hundreds of megawatts.
