Power will be out for about 700 United Illuminating customers in West Haven during a planned power outage on Sunday morning.
The United Illuminating Company is sending out advanced warning about a planned outage from 6 a.m. until 10 a.m. on Sunday and said the customers who will be affected have been notified by direct mail and other means.
UI officials said the outage is needed to upgrade a substation.
If weather is inclement on Aug. 25, UI will postpone the outage and announce a future date for the system upgrades.
Customers with questions, including those with medical conditions or generators, should call UI’s scheduled outage hotline at 877-491-9533.
