The Westport Generating Station (named after the Westport neighborhood where it stood) was a massive power plant which rested on the edge of Baltimore Bay. When it was opened in 1906, it was reputed to be the largest reinforced concrete building in the world. The lack of wood in construction made the station extremely fire resistant. Built by the Baltimore Gas and Electricity company, it worked in parallel with a hydroelectric plant to supply power to Baltimore and the surrounding area. The total capacity of the plant was 252 megawatts; about half the power was produced from steam turbines and the rest from combustion turbines. The original smoke stack stood 209 feet high, the tallest in Baltimore.
The plant was closed in 1993, and subsequently sealed shut using welded plate metal. The abandoned power station was a filming location for the move Twelve Monkeys (1995), and was demolished in 2008
