PJM — Heat wave drives record demand, demand response activated

• Peak Demand Record: PJM set all-time peak load of 168,158 MW on July 2, surpassing the previous 2006 record of 165,563 MW. Preliminary figures account for Demand Response program suppression. Find update at PJM Inside Lines.
• Demand Response Dispatch: PJM activated Pre-Emergency and Emergency Demand Response customers on July 2 and July 3 for afternoon/evening peaks, increasing system reserves. Voluntary DR compensation remains critical for peak management.
• Hot Weather Alert: Regional Hot Weather Alert extends through at least July 17. Maximum Generation Alerts and Load Management Alerts remain in effect signaling potential further DR activation.

NYISO — Summer capability period operational, ICAP tags routine

• ICAP Summer Cycle: NYISO ICAP summer capability period active with routine capacity accreditation and tag updates. Event calendar and UCAP calculations available on NYISO public portal reflecting normal mid-summer operations.
• Day-Ahead Pricing: No significant pricing anomalies reported. Zone spreads between NYC, Long Island, and Capital remain within structural patterns typical of July demand conditions.
• CBEP Program: Customer Benefit Emergency Participation program in standby mode. No emergency activations recorded during reporting period.

ERCOT — 4CP season active, adequate supply outlook maintained

• 4CP Monitoring: Currently in June-September 4CP calculation window. Load tracking below historical summer peaks; ERCOT anticipates sufficient generation to meet demand. Dashboard tracking available at ERCOT 4CP page.
• Grid Conditions: No Weather Watch, Watch, or Warning alerts issued as of reporting date. ORDC adders remain at baseline levels. Real-time reserve position healthy.
• Seasonal Assessment: ERCOT Summer 2026 preparations indicate stable resource positioning. Regulatory focus shifting toward development of 12CP methodology to replace 4CP (rulemaking underway).

ISO-NE — Capacity auction closed, market development progressing

• FCM Status: Forward Capacity Market 2026-2027 capacity year auction closed with sufficient resources procured. No de-list notices or show-cause requirements flagged for current operating period.
• Capacity Reforms: ISO-NE refined Capacity Auction Reforms (CAR) transition mechanism in July meetings with NEPOOL, focusing on market power and resource qualification rules in prompt capacity framework.
• Load Forecast: Seven-day capacity forecast within normal range for mid-summer. Peak load expectations aligned with seasonal norms; no capacity shortfall concerns for July-August period.

MISO — 2026/27 PRA cleared, capacity prices normalize

• Planning Resource Auction Results: 2026/27 PRA closed in April with 142.6 GW of summer capacity offers cleared (up 4.8 GW year-over-year). Reserve margin settled 3.5 percentage points above MISO’s 7.9% reliability target. Results published at MISO PRA Results.
• Capacity Pricing Trends: Summer capacity prices fell sharply to $424/MW-day in North/Central regions and $384-412/MW-day in southern zones, down from $666/MW-day year-over-year. Annualized pricing range $116-126/MW-day reflects ample supply and new solar contributions (12.2 GW accredited).
• Real-Time Settlements: Settlement cycles normal. Day 7, Day 14, Day 55, and Day 105 settlements processing as scheduled; no material make-whole payment clusters reported.

CAISO — Summer 2026 resource adequacy strong, healthy reserve margin

• 2026 Summer Loads and Resources: CAISO Summer 2026 assessment shows net resource surplus of 2,547 MW against industry planning targets. 2,127 MW of new RA-eligible capacity onboarded since September 2025; additional 6,194 MW expected by June 30, 2026, including SunZia wind (3,167 MW nameplate). Full assessment at CAISO 2026 Summer RA Assessment.
• Flex Alert Status: No Stage 1, 2, or 3 Flex Alerts issued. No emergency demand response activation required. Renewable curtailment minimal given adequate reserve positioning.
• NQC Compliance: Aggregate compliance with all monthly year-ahead RA requirements and flexible RA requirements across all five summer months confirmed. Planning reserve margin set at 18% plus effective PRM adder.

Cross-Market Watch — Summer demand peaks, regulatory focus on reform

• Peak Season Dynamics: July demand peaks concentrated in PJM-NYISO eastern region and ERCOT due to regional heat. Western capacity surplus limits any systemic stress. Demand response program efficacy demonstrated in PJM activation events.
• Regulatory/Policy Updates: ERCOT 4CP-to-12CP rulemaking advancing (replacing 5-day peak window with 30-minute intervals). ISO-NE prompt capacity market design refinements continue for future implementation. FERC monitoring all transitions; no emergency orders issued to date.
• Supply Trends: Solar capacity driving resource adequacy improvements across MISO and CAISO (12.2 GW and 3.2+ GW additions respectively). Battery storage and gas resources providing flexibility support in peak hours.
