Power has been restored to Pfizer in Groton and the surrounding area after strong winds brought down power lines Tuesday.
Electrical wires came down on Rainville Avenue and Benham Road, according to Groton Utilities. Officials said winds likely brought down a tree branch, which took down primary lines and sent surges through the system, which affected more lines in the area.
Power was also knocked out to traffic lights, so police put up stop signs to control traffic.
The utility company said power was out along Eastern Point Road and south of Rainville Avenue. Crews fixed the problem as of 3:22 p.m.
