Orange, CT — July 10, 2026 — Avangrid, Inc., a leading energy company and member of the Iberdrola Group, responded to a multi-state severe weather event that impacted more than 283,000 customers across New York, Connecticut and Maine during the Fourth of July holiday weekend.
"Over the course of one holiday week, our teams responded to multiple severe weather events across New York, Connecticut and Maine while managing record-breaking temperatures and periods of high energy demand," said Avangrid CEO José Antonio Miranda. "Thanks to strong coordination across our operating companies, support from mutual assistance partners and ongoing investments in grid reliability, we were able to safely restore service and keep energy flowing when it was needed most. These increasingly extreme weather events also highlight the critical, urgent need to invest in modernizing and strengthening our energy infrastructure to ensure reliability for our customers and communities.”
Beginning July 1, multiple rounds of storms moved across the Northeast while temperatures and heat index values climbed above 110 degrees in some areas. Avangrid coordinated restoration efforts across Rochester Gas and Electric (RG&E), New York State Electric & Gas (NYSEG), Central Maine Power (CMP), and The United Illuminating Company (UI), deploying more than 1,370 personnel and support resources.
RG&E experienced significant impacts on July 1, followed by severe damage in NYSEG's Mechanicville Division on July 2, particularly in the Chatham area. On July 4, a powerful line of thunderstorms swept through the Hudson Valley, Connecticut and portions of Maine, affecting NYSEG's Brewster Division, UI's service territory, and CMP's Portland and Alfred service areas.
Crews from across Avangrid’s operating companies worked around the clock throughout the holiday weekend to restore service. On July 5, resources from New York and Maine were mobilized to support restoration efforts in Connecticut and the Hudson Valley. Power was fully restored to UI customers by July 6 and NYSEG customers by July 7.
At the same time, Avangrid’s Energy Control Centers continuously monitored system conditions and coordinated with regional grid operators to maintain reliability during periods of exceptionally high electricity demand.
