Companies named in the reporting of this entry (being named is not a finding of fault): United Illuminating

A transformer fire in New Haven, Connecticut, was reported to have cut power on the afternoon of 9 September 2026. Yale University said power was out in the area of 2 Science Park (50 Division Street) and 25 Science Park (150 Munson Street). Winchester Avenue was closed from Munson Street to Division Street. The university said power had been restored and the area was clear as of 5:10 p.m. More than 2,000 United Illuminating customers in New Haven were without power when the outage was first reported, and thirteen were still without power at 5:45 p.m. The cause of the fire was not reported.

Not reported.

  1. Alerts that name the affected streets help nearby users and responders act quickly.
  2. A short road closure around a transformer fire can keep the public clear while the fault is made safe.
  3. Customer counts should be checked again after the first restoration report, because a small number of supplies can remain off.
