Ten days after Tropical Storm Irene slammed the Connecticut coast, knocking out power to more than 16,000 customers in Fairfield, United Illuminating reports at 5 p.m. Wednesday that all electric service has been restored in town.

The number of local outages fluctuated throughout day, UI said, ranging from a single customer in the dark at 6 a.m. to several dozen in the early afternoon.

The fluctuations were caused primarily because the repair process required some areas to have power shut down by utility crews so that other neighborhoods can have service restored.

At the peak of the storm, roughly three-quarters of Fairfield was blacked out, or 16,606 customers, among the total of 22,194.
