More than 6,000 customers were without power in Trumbull County Saturday afternoon.
Power in several parts of the county including Vienna, Liberty and Brookfield went out around 3 p.m.
Robin Patton with First Energy said the outage was caused by a tree that fell on a transmission line in Vienna.
Service was restored in Liberty around 3:30 p.m. Brookfield and Vienna customers are still without power. Patton said power should be completely restored by 5:30.
