White Bay Power Station was initially built by NSW Rail Commissioners to provide power for Sydney's growing rail network.
The power station was constructed in two stages. The first stage, built between 1912 and 1917, consisted of a boiler house, standing roughly where the present boiler house stands, and part of the turbine hall and switch house. The second stage, which commenced in 1925, saw the completion of the turbine hall and switch house.
