PJM — Capacity auction clears at price cap amid heat stress

• 5CP Capacity Tags: 2026/27 Base Residual Auction cleared 134,311 MW at price cap of $329.17/MW-day (22% increase year-over-year). Gas generation is 45% of cleared capacity; nuclear 21%; coal 22%. This is the highest capacity price and signals tight supply-demand balance driven by data center load growth exceeding 5,500 MW. PJM capacity auction report.
• Real-Time LMP and Load: PJM’s July heat wave pushed peak load to 168,158 MW on July 2, approaching the 165,563 MW historical record from 2006. Hot weather operations extended through mid-July. Real-time market data available via PJM data viewer.
• Demand Response: Demand response programs continue to suppress peak load; 2,669 MW of new generation and uprates cleared in this auction, signaling supply response to price signals. No active emergency dispatch documented for today.

NYISO — Reliability margins at critical lows entering late summer

• ICAP and Reliability Margins: NYISO continues to operate with “the lowest reliability margins in recent history” due to an aging generation fleet and extreme summer heat. Peak load during earlier July heat waves reached 32,410 MW, testing tight margins. Current ICAP market data available at NYISO ICAP portal.
• Heat Wave Impact: July heat wave created structurally elevated risk of blackouts given resource performance challenges. NYISO issued multiple energy warnings as extreme temperatures persisted through early July. No emergency alert documented for July 23, but structural concerns remain as summer continues.
• Day-Ahead Pricing: Pricing during peak heat periods reflected scarcity; normal conditions returning as temperatures moderate. Monitor NYISO’s energy market data portal for day-ahead signals.

ERCOT — 4CP season active; past first heat dome

• 4CP Season and ORDC: Four Coincident Peak (4CP) qualification period runs June through September. ERCOT managed a maximum generation emergency declaration during an earlier July heat dome that pushed demand to peak levels. No ongoing grid emergency or ORDC adders firing as of July 23. ERCOT 4CP data.
• Grid Condition Alerts: No Weather Watch, Watch, Warning, or Emergency Alert currently in effect. ERCOT uses TXANS (Texas Advisory and Notification System) to communicate future high-demand periods; check TXANS for forward-looking conditions.
• Capacity Position: Supply demonstrated adequate response during July heat dome. Texas typically sees peak demand in August; remaining 4CP season will likely see elevated ORDC monitoring in coming weeks.

ISO-NE — Load conditions easing post-heat wave

• FCM Capacity Market: Forward Capacity Market value declined to $78 million in June 2026 (13% decrease month-over-month and year-over-year), reflecting adequate supply position. July 2026 System & Market Operations Report shows structured market health. ISO-NE ops report.
• Load Forecast: Peak load projections during mid-July heat wave reached 25,850 MW with expectations of “exceptionally tight operating conditions.” Current conditions have stabilized with temperatures moderating. Seven-day capacity forecast available at ISO-NE forecast page.
• Resource Status: No de-list bids or capacity qualification issues reported in recent activity. New England’s generation mix remains stable heading into late July.

MISO — Emergency procedures used; capacity auction shows moderation

• Planning Resource Auction Results: 2026/27 PRA cleared with annualized capacity prices of $116–$126/MW-day across the 10 zones, down sharply from prior-year prices. Summer 2026/27 pricing: $424/MW-day (North/Central), $384/MW-day (Arkansas/Mississippi), $412/MW-day (Louisiana/Texas). About 12.2 GW of accredited solar cleared, up 59% from prior year. MISO PRA results.
• Heat Dome Operations: MISO declared maximum generation emergency during an earlier July heat dome that drove demand to 122 GW across its footprint. Emergency procedures have been stood down; current conditions are within normal parameters.
• Zonal Pricing: Summer pricing remains above winter on a basis spread; however, the significant capacity clearing suggests Zone 4 (Illinois) resource adequacy concerns have been addressed. No active zone-level constraints reported.

CAISO — Demand response on standby; no Flex Alerts active

• Flex Alerts and Curtailment: No Stage 1, 2, or 3 Flex Alerts issued for July 23, 2026. Demand response programs remain available and callable under emergency conditions. Curtailment of renewables is managed day-to-day but is not a primary constraint today. CAISO demand response programs.
• Resource Adequacy and NQC: California’s Net Qualifying Capacity (NQC) portfolio has been augmented by solar growth across the region. No resource adequacy deficiency notices issued. Current balancing conditions are stable.
• Forward Outlook: California continues to monitor late-July and August demand patterns. Flex Alert readiness remains in effect as a precaution, but current conditions do not warrant emergency measures.

Cross-Market Watch

• Heat Wave Recap: Extended heat dome across the Eastern U.S. (early-to-mid July) drove multiple ISOs to elevated operations. PJM and MISO both experienced peak load records or near-record conditions, while NYISO contended with the lowest reliability margins on record. U.S. electric generation hit 100,996 GWh for the week of June 28–July 4, 2026 — a national record — as air-conditioning demand surged across regions.
• Regulatory Status: No NERC Level 1 or 2 emergency alerts active as of July 23. NERC previously issued a Level 3 alert (May 2026) focused on large computational loads. No new FERC orders affecting market operations this week. Capacity auction results demonstrate supply-side response to price signals across multiple regions.
