Connecticut's Public Utilities Regulatory Authority has found that the state's two largest power companies did not meet certain acceptable performance standards in preparing for and responding to Tropical Storm Isaias.

Today's final decision concludes an eight-month investigation following Gov. Ned Lamont's request for PURA to investigate how Connecticut's Electric Distribution Companies Eversource and United Illuminating prepared for and responded to the Aug. 4, 2020 storm.

An estimated 1 million Connecticut residents were in the dark, some for as long as two weeks, after the tropical storm tore through Connecticut.

Today's decision will now require the two companies to make several enhancements to their emergency response plans.
