The Sheerness Mine is a 7,000 Ha. surface strip mine located in South Central Alberta south of the Town of Hanna. The mine operates two active pits and supplies sub-bituminous coal to the two generating units at the Sheerness Generating Station which is owned by TransAlta Utilities and ATCO Power and operated by ATCO Power. The mine has been supplying coal to the station since 1984.
Coal is uncovered using the two draglines (1 – BE 1300; 1 – Page 736). The exposed coal is hauled directly from the mine to the generating station. Current annual production of the mine is 3.3 million tonnes. The current coal supply contract for the mine expires in 2026.
In 2014, Sheerness Mine achieved 19 years without a lost time accident. Work is underway to explore adjacent properties and greenfield opportunities for life extension of the mine to the end of the expected plant lives (2040).
