Brighton B Power Station was replaced in 1998 by the new 400MW Combined Cycle Gas Turbine power station. The old power station had 2 chimneys which were each 107metres (354ft) tall. The new station's single chimney is 100metres tall (330ft) and is not the tallest building in Brighton. Sussex Heights, Brighton's concrete monstrosity is the tallest building, standing at 140metres (462ft).
