Designed by
Jesse Hartley, the dock opened on 16 September 1830. Clarence Dock was named after William, Duke of Clarence, who became
William IV. It was built as a self-contained steamship dock facility. The dock was the principal berth for the Irish ferry ships. During the Irish famine in the 1840s over 1.3 million Irish people travelled through the dock. After many weeks or months, many took a ship to America from
Waterloo Dock, there being fewer direct sailings to America from Ireland at this time. However many thousands made their home in Liverpool. Others moved to London and other British towns and cities in search of work.
Clarence Dock power station Clarence Dock power station was constructed for Liverpool Corporation in 1931 to be an integral part of the local electricity grid system supplying electricity throughout Liverpool. The station plant comprised a low pressure station (No. 1) and a later high pressure station (No. 2) both based on coal-fired, water tube boilers and steam turbine driven
alternators. The plant in the low pressure station (installed 1931–32) comprised: Boilers (all coal-fired) • 4 × 160,000 pounds per hour (20.16 kg/s) of steam at 450
psi and 775 °F (31.0
bar and 413 °C) • 4 × 200,000 lb/hr (25.20 kg/s) of steam at 450 psi and 775 °F (31.0 bar and 413 °C) Turbo-alternators • 2 × 51.25 MW twin cylinder
Metropolitan-Vickers, 1,500 rpm, 7,250 kV, 3-phase, 50 Hz. The plant in the high pressure station (installed 1937–53) comprised: By 1972 the No. 1 station had been decommissioned and the No. 2 station converted to oil firing. The No. 2 station was decommissioned in the early 1980s. The three large chimneys of the Clarence Dock Power Station were a familiar local landmark, known as the
Three Sisters, until the power station was demolished in 1994. ==Present==
