PJM — Operating under a DOE emergency order as the week’s heat wave winds down

• 5CP Capacity Tags: This week is a strong 5CP candidate window. PJM served a preliminary peak of 151,105 MW on July 14 and forecast roughly 164,078 MW for July 15, 160,227 MW for July 16 and 150,981 MW for today, per the July 15 hot weather operations update. These hours compete with the July 2 all-time preliminary peak of 168,158 MW for capacity tag positions.
• Real-Time LMP: A Maximum Generation Alert and Load Management Alert were in effect July 15-16, and a Hot Weather Alert continues through at least July 17. A U.S. Department of Energy emergency order, effective July 15-21, gives PJM temporary environmental permit relief and last-resort authority to curtail data centers and other large loads, per Utility Dive.
• Demand Response: The Load Management Alert signals that Pre-Emergency and Emergency DR could be declared. Roughly 6,000 MW of DR was activated during the July 2 record event, and performance calculations are underway during the 60-day review period.

NYISO — Thin summer margins with a key NYC import line offline

• ICAP Tag Tracking: NYISO’s summer reliability assessment shows the thinnest margins in recent history, with 34,615 MW of resources against a 31,578 MW forecast peak; an extended 95-degree heat wave would push the capacity margin to roughly -1,679 MW absent emergency actions, per Utility Dive. Hot mid-July afternoons remain live candidates for the ICAP peak-setting hour.
• Day-Ahead Pricing: The Champlain Hudson Power Express, NYC’s 1,250 MW hydro import line, tripped offline July 4 for the second time since activation and remained out of service in the latest reporting from RTO Insider. The outage supports NYC zone price premiums during heat-driven load.
• CBEP Program Alerts: No CBEP alerts or activations were reported in the last 24 hours.

ERCOT — Quiet grid, but the heart of 4CP season demands daily attention

• 4CP Season Tracking: Mid-July sits in the core of the June-September 4CP window. Hot late-afternoon intervals on high-load days remain candidate coincident peaks, and large C&I loads should be on daily 4CP watch via ERCOT’s grid and market dashboards.
• ORDC Pricing: No high ORDC events or reserve shortfalls were flagged in the last 24 hours. ERCOT’s summer 2026 outlook anticipates sufficient generation, supported by substantial new solar and battery capacity added since last summer.
• Grid Condition Alerts: No Weather Watch, Warning, Emergency or Conservation Alerts were in effect per ERCOT’s TXANS notification system.

ISO-NE — No scarcity events; summer outlook remains adequate

• Load Forecasting: ISO-NE expects a summer peak near 25.2 GW under typical weather and roughly 26.5 GW under above-average heat, and reports the region is positioned to meet demand, per its seasonal system outlook. No capacity scarcity conditions were reported in the last 24 hours.
• FCM Tag Events: No new qualification events, de-list bids or show-cause notices surfaced. Structurally, ISO-NE has trimmed its 10-year demand forecast on a slower electrification outlook, a factor for forward capacity positions.

MISO — Maximum generation emergency declared in second July heat dome

• Real-Time Settlements: MISO declared a maximum generation emergency July 15 as a days-long heat dome over MISO Midwest drove demand to roughly 122 GW, the second time this month the RTO has resorted to emergency procedures, per RTO Insider. Expect elevated settlement and make-whole activity from the event intervals.
• Zonal Pricing: Tight reserves and emergency conditions across the Midwest footprint imply elevated congestion and zonal spread risk; monitor MISO’s real-time operations notifications for the current declaration status as the heat dome exits.
• Planning Resource Auction: No new PRA developments in the last 24 hours. Note that MISO’s simplified Max Gen event steps, effective June 1, now align directly with NERC EEA levels, changing how emergency stages are communicated.

CAISO — Calm conditions and a healthy resource adequacy cushion

• Flex Alerts: No Flex Alerts or emergency notifications were issued in the last 24 hours, per CAISO’s emergency notification history.
• Renewable Curtailment: Routine midday solar curtailment continues at seasonal levels, with more than 16 GW of battery storage shifting energy into evening peaks; no unusual overgeneration events were reported.
• NQC Integration: CAISO’s 2026 summer assessment shows a roughly 2,547 MW reliability surplus under standard planning targets, with about 6.2 GW of new RA-eligible capacity expected online by the end of June. No RA deficiency notices surfaced.

Cross-Market Watch — Heat dome drives emergencies East; capacity prices hit the cap

• Extreme heat: The second heat dome of July pushed both PJM and MISO into emergency procedures this week, and DOE issued its fifth grid emergency order of the summer, this one for PJM through July 21, per POWER Magazine.
• Capacity markets: PJM’s latest capacity auction cleared at the $325/MW-day price cap and fell 6.8 GW short of its reliability requirement, procuring 138,318 MW, per RTO Insider and PJM. A third consecutive cap-clearing result signals sustained upward pressure on capacity costs for load.
• Regulatory: FERC’s show-cause directive requiring RTOs to address large-load interconnection continues to generate filings across markets, per RTO Insider.
