Frequency Clock (1924)

This clock was used to calibrate steam turbines at the Estevan Generating Station. It contains two clocks; an accurate mechanical pendulum clock that provides real time, and a synchronous motor clock that relies on the system frequency. In 1911, Estevan's municipality owned and operated a power station which was sold to Dominion Electric in 1928. In 1930, Dominion Electric turned it into a coal burning facility. In 1946, SaskPower purchased the facility and added expansions throughout the 1950s.
