PJM — Heat wave continues to stress system with demand near all-time peak

• Real-Time Demand: Instantaneous load reached 162.7 GW on July 2, within 3 GW of the all-time 2006 record of 165.6 GW. July 20 forecast suggests potential for new peak as heat wave persists across mid-Atlantic. Source
• Emergency Response Active: DOE emergency order issued for maximum generation dispatch, including all fossil fuel plants and dual-fuel units. Source
• Demand Response: Robust DR participation prevented demand from breaking the 2006 record during early July peak. Virtual power plant programs actively discharging battery resources during event windows.

ERCOT — 4CP season with extreme heat risk documented by NERC

• 4CP Season Tracking: July is within the June–September 4CP window. NERC 2026 Summer Assessment identified western ERCOT as a higher-risk area under extreme weather conditions. Source
• Load vs. Capacity: Extreme heat across Texas contributing to near-peak or peak conditions. Grid Conditions dashboard available for real-time monitoring of reserve margins and ORDC adders. Source
• Rule Changes Pending: Texas regulators developing replacement of 4CP with 12CP methodology measured in 30-minute intervals, with implementation timeline TBD.

ISO-NE — Summer season with elevated risk in northeast corridor

• NERC Risk Assessment: Northeast Power Coordinating Council–New England identified as a higher-risk area under extreme weather conditions with cumulative 0.655 days of LOLE estimated for July-August. Source
• Capacity Forecast: Seven-day capacity forecast updated regularly through ISO Express. Resource availability tight but adequate under base assumptions. Source
• FCM Status: Forward Capacity Market operations nominal; no active qualification events or show-cause orders as of recent filings.

NYISO — Summer ICAP operations with routine zonal activity

• ICAP Tag Tracking: Installed Capacity market operating normally through summer tag period. Public portal (icappublic.nyiso.com) shows current UCAP calculations and event calendar with no emergency de-listings or capacity deficiency notices. Source
• Day-Ahead Pricing: Zone-level spreads (NYC, Long Island, Capital) within seasonal norms. Real-time dashboard reflects summer demand patterns. Source
• CBEP Program: No Customer Benefit Emergency Participation alerts active at this time.

MISO — Adequate supply across all zones; capacity prices moderate following 2026/27 PRA

• Planning Resource Auction Results: April 2026 PRA cleared at $424–$412/MW-day in North and Central regions, $384–$412/MW-day in southern zones, down from $666.50/MW-day year prior. Annualized summer capacity $116–$126/MW-day across 10 zones indicates robust supply. Source
• Zonal Pricing: No structural congestion or transmission constraints reported. Solar accreditation up 59% to 12.2 GW, increasing resource adequacy headroom. Source
• Real-Time Settlements: Normal settlement interval activity; no make-whole payment spikes or anomalies flagged.

CAISO — Summer assessment confirms sufficient resource margin for July

• Resource Adequacy: 2026 Summer Loads and Resources Assessment projects peak of 46.8 GW on September 2, with July peak 543 MW lower. Probabilistic resource portfolio assessment shows 2,547 MW excess above 1-in-10 LOLE target under all load, solar, wind, and outage scenarios. Source
• Flex Alerts: No Stage Flex Alerts active as of July 20. July benefits from approximately 3.6 GW more solar during peak than base case load assumptions.
• Renewable Integration: Solar and wind curtailment managed within normal parameters; no overgeneration events requiring emergency action.

Cross-Market Watch

• Heat Wave Impact Across Multiple Regions: Early July heat wave drove demand to near-record levels in PJM mid-Atlantic and stressed grids in ERCOT and ISO-NE. NERC 2026 Summer Reliability Assessment identified July and August as periods of greatest cumulative risk (0.655 days LOLE, 2.004 hours LOLH, 1,262 MWh EUE).
• NERC Level 3 Alert on Large Loads: May 2026 alert focused on computational load modeling and demand-side flexibility as critical to summer reliability, particularly for data centers and AI infrastructure. Source
• Regulatory Momentum on Demand Response: FERC and DOE actions highlight demand flexibility and virtual power plants as essential reliability tools during extreme weather events.
