The Baltimore Gas and Electric Company Building is a historic office building located at Baltimore, Maryland, United States. It is the former headquarters of the old Consolidated Gas, Light and Electric Power Company of Baltimore City, which was a merger at the turn of the 20th century of the former century old Gas Light Company of Baltimore with several other formerly competing gas and electric power companies which had risen in the late 19th century, to form a single metropolitan wide unified utility system. In 1955, the old cumbersome Consolidated title was jettisoned and the utility rebranded as the Baltimore Gas and Electric Company (BG&E).
