On 12 Oct 2026 the Secretary of Energy issued emergency Order No. 202-26-50 to PJM Interconnection, effective 13–16 Oct, after PJM forecast it would come within 900 MW of its reserve margin with roughly a third of its generating fleet offline for seasonal maintenance during unseasonably warm weather [1][4]. The order authorizes PJM to run specified plants beyond environmental permit limits and, as a last resort before or during an Energy Emergency Alert 3, to direct data centers and other large loads onto backup generation; hospitals, 911 centers, and water facilities are exempt [1]. S2 assesses region-wide rolling blackouts as unlikely (5–10%) through 16 Oct, with somewhat higher but still low risk of localized rotating outages in the Baltimore, Washington DC/suburban Maryland, and Virginia zones. Hospitals are well protected for short rotating outages; the more probable impact is emergency department strain from medically dependent residents at home.

Section 202(c) of the Federal Power Act allows the Secretary of Energy, during a declared emergency caused by a sudden demand increase or a shortage of generation or transmission, to order generation, delivery, interchange, or transmission of electricity [1].

PJM Interconnection is the regional grid operator and Reliability Coordinator for all or parts of 13 states and the District of Columbia, serving more than 67 million people [1][7]. Total PJM generating capacity is approximately 182,000 MW [8].

Mid-September through early December is PJM’s seasonal outage window, when generators and transmission lines are scheduled down for maintenance ahead of winter [9].

Order 202-26-50 is at least the fifth DOE emergency order issued to PJM in 2026, following orders in January, mid-May, early July, and early September [9]. PJM attributes recurring stress to baseload demand growing faster than new capacity and unpredictable weather shrinking the available maintenance window [6]. Data center load growth is reported as the primary driver of load growth in the region [7].

• Permit barriers: Many generating units hold air and water permits that limit run-hours, emissions, or fuel throughput. PJM identified units that could encounter operational limits from environmental permits or state requirements [1]. A 202(c) order authorizes operation beyond those limits and excludes emergency-period emissions from rolling-average permit calculations [1].
• Backup generation restrictions: Data center and large-load backup generators are generally permitted for on-site emergency use only. The order is the mechanism that allows PJM to direct those resources to operate for grid relief [1].
• Statutory triggers: Section 202(c) requires a sudden increase in demand or a shortage of generation or transmission facilities. The order cites all three: unseasonable heat, roughly a third of PJM capacity offline for maintenance, and planned transmission outages constraining imports [1][8].
• Structural load growth: Data center demand is reported as the primary driver of regional load growth, with new generation and transmission unable to keep pace [7]. PJM states that baseload demand is growing faster than new capacity and that unpredictable weather is reducing the days available for maintenance and construction [6].
• Recurring use in 2026: Order 202-26-50 is at least the fifth DOE emergency order to PJM in 2026 [9].
• Plant-retention orders (separate category): DOE has also issued longer 90-day 202(c) orders directing specific plants to remain available to operate, including Eddystone Units 3 and 4 in Pennsylvania (Aug–Nov 2026), F.B. Culley Unit 2 and R.M. Schahfer Units 17 and 18 in Indiana (Sep–Dec 2026), and Stanton Unit 1 in Florida (Sep–Nov 2026) [12][13][14][15]. Order 202-26-50 differs: PJM requested it, and it lasts four days [1].

DATE (2026)	EVENT
11 Oct	PJM submits 202(c) application to DOE; recalls all active generation maintenance outage tickets, effective noon 14 Oct [1][3].
12 Oct	DOE issues Order 202-26-50. PJM issues Maximum Generation Alert and Load Management Alert for 13 Oct; Capacity Advisory in place 12–14 Oct. MISO issues Capacity Advisory and Conservative Operations [1][3].
13 Oct	Order takes effect. PJM issues a Pre-Emergency Load Management action covering afternoon peak and the evening net-load peak when solar output falls to zero; alerts extended through 14 Oct. Generation outages approx. 61,000 MW [4][8].
14 Oct	Maintenance outage recall takes effect at noon. Above-normal temperatures persist, with hotter conditions South and West [4].
16 Oct	Order expires. Renewal, if needed, must be requested before expiration [1].

• PJM forecast demand at or above 111,500 MW on 13 Oct and projected being within 900 MW of its reserve margin on 14 Oct, with generation outages reaching 61,591 MW. The most acute conditions are in the BGE, PEPCO, and Dominion zones [1].
• PJM’s published load forecast was 103,125 MW (Mon 12 Oct), 112,447 MW (Tue 13 Oct), and 112,282 MW (Wed 14 Oct) [8].
• Transfer constraints limit deliverability: north-to-south on the Conastone–Peach Bottom 500 kV facility, west-to-east on the Crete–St. Johns 345 kV tie with MISO, and MISO–PJM seams transfers limited by loading on the Fostoria–Lallendorf facility [1].
• PJM also carried significant firm export obligations and notified neighboring grids to prepare for reduced imports from PJM [1][4].

• PJM may dispatch units listed in Exhibit A (Specified Resources) as needed to maintain reliability, and may add units with prompt written notice to DOE [1].
• PJM may direct backup generation (auxiliary, standby, directly connected, or battery storage) at data centers, including hyperscale facilities, and other large industrial and commercial sites to operate as a last resort before an EEA 3 (firm load interruption) or during an EEA 3 [1].
• Exempt from the backup-generation provision: defense, homeland security, first responder, air traffic control, hospital, 911, water and wastewater, and natural gas pipeline and gathering facilities [1].
• PJM anticipates exceedances of permit limits for sulfur dioxide, nitrogen oxides, carbon monoxide, wastewater, ammonia, and fuel throughput. Emissions during the order will not count toward rolling-average permit limits [1].
• Rate recovery is available under the statute [1]. PJM must report daily to DOE on each resource operated under the order [1].

• PJM states the alerts require no customer action and has not asked residential customers to conserve [4][10].
• PJM states it has not used large-load backup generation under any 2026 order to date [4].
• Media reporting characterizes the order as intended to reduce the risk of service interruptions rather than to announce planned blackouts [7]. Some social-media reporting has framed the event in more alarming terms than official statements support [11].

S2 assesses that rolling blackouts across the PJM region through 16 Oct are unlikely. Forecast demand of roughly 112,000 MW is far below the 166,000+ MW PJM forecast during the July heat event [9]. The noon 14 Oct maintenance recall should return generation to service during the highest-risk window, and several mitigation layers remain before firm load shed: demand response, export curtailment, voltage reduction, and large-load backup generation.

Risk is concentrated in the BGE, PEPCO, and Dominion zones (Baltimore, Washington DC/suburban Maryland, Northern and Central Virginia), where the tightest conditions coincide with the transmission constraints limiting imports. A 900 MW margin is roughly equivalent to the loss of one large generating unit; an unplanned trip during the evening net-load peak is the most likely path to localized rotating outages.

Hospitals are likely to be insulated from direct impact. Utilities typically place hospitals on priority or critical-load circuits excluded from rotation where circuit topology permits, though this is not guaranteed for facilities sharing a feeder with general load. Accredited hospitals are required to restore life-safety and critical-care branches on emergency generation within 10 seconds (NFPA 99/110), and Order 202-26-50 expressly prevents PJM from drafting hospital backup generators.

Operational degradation on generator power is likely if outages occur: essential electrical systems typically exclude full HVAC and chiller plant, which matters during unseasonal heat, and elective procedures and some imaging (MRI, some CT) may be deferred.

The more significant hospital impact would be indirect. Residents dependent on home oxygen concentrators, ventilators, powered mobility devices, home dialysis, or refrigerated medications are likely to present to emergency departments if outages extend beyond 30–60 minute rotations. Heat-related illness and degraded traffic signals and water pressure would compound EMS and ED load in the Baltimore–Washington–Northern Virginia corridor.

Adversary threat considerations: S2 assesses with moderate confidence that the current emergency is not adversary-driven. The emergency finding rests on demand, planned generation outages, and planned transmission outages [1]; an attack would more likely present as a surge in forced, simultaneous outages, which has not been reported. DOE also invoked Section 202(c), its routine supply-shortage authority, rather than the separate FPA Section 215A grid security emergency authority created for cyber and physical attacks, and no corroborating CISA, FBI, or E-ISAC messaging is visible. The adversary threat to the grid nonetheless remains real: U.S. agencies have reported PRC state-sponsored actors maintaining persistent access to U.S. critical infrastructure networks [17], and EO 14421 (Aug 2026) cited growing cyber threats from foreign actors including China and Iran [18]. Industry speakers have warned that adversaries may exploit periods of severe grid stress to launch physical or cyberattacks [19]. The principal risk is opportunistic exploitation of the tight operating window, not causation. Indicators that would change this assessment: a Section 215A declaration or energy-sector CISA/FBI/E-ISAC alert, a spike in forced generator trips, reported utility intrusions in the BGE, PEPCO, or Dominion zones, or an order renewal not explained by weather. Classified threat reporting, if any, would not appear in a public 202(c) order.

A 202(c) order also shifts accountability. Placing the directive to operate beyond permit limits with the Secretary of Energy protects plant owners from enforcement exposure, and it documents that PJM exhausted lawful options before any firm load shed, which matters if outages later occur [1].

The longer plant-retention orders are contested. The administration frames them as reliability measures, while critics argue that using emergency authority to retain uneconomic plants raises ratepayer costs and dilutes market signals for new supply [16]. S2 notes this policy debate is distinct from the short-duration, operator-requested order addressed in this report.

Beyond this event, the recurrence of emergency orders outside traditional peak seasons indicates structural supply tightness that is likely to persist into winter 2026–27.

Probability ranges are S2 analytic judgments based on open-source reporting available as of DTG. Assessment may be revised as additional information is developed.

• Contents of Exhibit A Specified Resource list and updates filed 12–13 Oct.
• Real-time EEA status and actual reserve margins on 14–16 Oct.
• Temperature forecast for 15–16 Oct across the BGE, PEPCO, and Dominion zones.
• Utility-specific load-shed rotation plans and which hospitals share feeders with rotatable load.
• Aggregate capacity and on-site fuel of data center backup generation in the affected zones.
• Whether PJM intends to request renewal of the order.
• Classified or non-public threat reporting on adversary activity targeting PJM-zone utilities, and forced-outage data for 13–16 Oct.

• Monitor official channels: Track PJM emergency procedures and local utility outage maps through 16 Oct; treat social-media “blackout” claims as unverified until confirmed by PJM or the utility.
• Medically dependent residents: Charge backup batteries for oxygen concentrators, CPAP/BiPAP, and powered mobility devices; confirm enrollment in utility medical-priority programs; maintain a cooler plan for refrigerated medications.
• Heat exposure: Identify a cooling location in case of a daytime outage; check on elderly neighbors and those without air conditioning.
• Voluntary load reduction: Shift discretionary electricity use away from late afternoon and the early-evening peak when solar output drops.
• Generator safety: Operate portable generators outdoors only, away from windows and vents, to prevent carbon monoxide poisoning; verify fuel on hand.
• Healthcare facilities: Verify generator fuel levels and transfer-switch testing, confirm critical-load status with the serving utility, and prepare ED surge plans for durable-medical-equipment patients.
• Travel: Expect dark traffic signals during any outage; treat them as four-way stops.

Area of concern: Operators in DE, IL, IN, KY, MD, MI, NJ, NC, OH, PA, TN, VA, WV, and DC — priority attention to the Baltimore, Washington DC/suburban Maryland, and Virginia areas.

Communications posture: PACE Primary — no change. Be prepared to shift to Alternate if localized outages affect commercial power, cellular, or internet service.

Station readiness: Verify battery and generator capacity to sustain station operations for a minimum of 24 hours.

Reporting: Report any utility outage, EEA declaration, or public conservation appeal through MAGNET situational awareness channels with location, time (Zulu), and observed scope.

Served agencies: Be prepared to support served agencies and healthcare coalitions if requested; do not self-deploy.

Information discipline: Do not relay unverified blackout claims; attribute all reports to their source.
