Power was restored last night to the remaining 300 Baltimore Gas and Electric Co. customers in Lansdowne who were among the 14,000 homes and businesses who lacked power for most of yesterday after a pole fire cut electricity there and in Halethorpe, a spokesman for the utility said.

The cause of the 8:40 a.m. fire wasn't known, said the spokesman, Charles Franklin. By 1 p.m., the utility had restored power to all but 700 customers, Mr. Franklin said. The final 300 customers had power by 8:30 p.m.

A BGE service operator had put out the fire by the time the Baltimore County Fire Department responded, he said.
