Overview

Jefferies noted that U.S. investor‑owned utilities experienced significant performance challenges during early July 2026 because of a combination of extreme heat and severe storms. The most disruptive outages occurred overnight into July 4, primarily in Michigan and New Jersey, with Pennsylvania recording the highest number of separate outage events on July 5.

Outage Details

  • In Michigan, DTE Energy reported that more than 100,000 customers were without power on Sunday evening, marking the longest and largest outage among the affected utilities. The state’s reliability metrics remain below average, a factor Jefferies highlighted as a risk for utilities operating there.
  • CMS Energy also faced outages in Michigan, though the exact customer count was not disclosed.
  • In New Jersey, FirstEnergy and Public Service Enterprise Group (PEG) experienced major interruptions.
  • WE Energies, a subsidiary of WEC Energy Group, was the only notable outage on July 2, affecting approximately 31,000 customers, roughly 3 % of its total customer base.
  • Across the broader region, additional utilities reported smaller-scale disruptions, but no specific customer figures were provided.

Grid Demand and Emergency Measures

PJM Interconnection recorded a peak electric demand of 162.7 gigawatts on July 2, which fell short of its forecasted 167.0 gigawatts. To avoid setting a new demand record, PJM deployed up to 6 gigawatts of emergency demand‑response resources and declared a maximum‑generation emergency that evening, a status that could trigger potential penalties for participating generators.

Regulatory and Corporate Actions

  • The New Mexico Public Regulatory Commission, in a 2‑1 vote, issued a final order voiding a $400 million private‑investment‑in‑public‑equity (PIPE) transaction between TXNM Energy and Blackstone that had been announced in June 2025. The commission did not require a full refiling of the merger case.
  • Baltimore Gas & Electric, an Exelon subsidiary, filed a rate case on July 2 seeking a $156 million increase. If approved, the increase would raise the average residential monthly bill by 4 %, equivalent to about $8 per month.
  • Approximately 1,600 unionized workers at PECO Energy commenced a strike, adding labor‑related pressure to the utilities sector during the same period.

Implications

The confluence of weather‑driven outages, demand‑side stress, and regulatory actions underscores heightened operational and financial risk for investor‑owned utilities in the affected regions. The voided TXNM‑Blackstone PIPE and the BGE rate case illustrate ongoing regulatory scrutiny and the potential for cost pass‑through to consumers, while the PECO strike highlights labor‑related vulnerabilities.
