Defects in power lines were blamed by Baltimore Gas and Electric Co. for two separate power outages yesterday that affected more than 1,100 homes and businesses in Annapolis and downtown Baltimore.

The first outage, from 1 p.m. to 2:30 p.m., occurred in Annapolis and affected 1,105 BGE customers. Those indoors reported dimmed lights; others, temporary loss of electricity.

By 3 p.m., 28 customers in downtown Baltimore were plunged into darkness when a feeder line failed. The blackout lasted for a few seconds as power was rerouted to a second feeder, said BGE spokesman Charles Welsh.
