Boundary Dam Power Station

Boundary Dam Power Station is a coal-fired station located in the RM of Estevan. It consists of six units with a combined generating capacity of 813 net MW. The first two 62 net MW units were com-missioned in 1959, with two more 139 net MW units added in 1970, a 139 net MW unit in 1973 and a final unit (273 net MW) added in 1978. In July 2003, a long term project to reduce air particulate emissions by installing electrostatic precipitators on all units was completed.

A new fly ash load out and storage facility was opened at the power station by SaskPower 2012. Construction of the Boundary Dam facility tripled the fly ash storage capacity to 5,000 tonnes. SaskPower wanted to find a company that could help maximize fly ash sales, given the increased storage capacity and the steady demand for the high quality of fly ash. All this was unique to Boundary Dam. Boundary Dam has also been selected as the site for a $1.4 Billion clean coal expansion. This expansion would convert the power station to a near zero emission plant, creating a resource (carbon) that can be used for enhanced oil recovery through carbon sequestration.

 

Shand Power Station

Shand Power Station is another coal-fired station in the RM of Estevan. Shand, commissioned in 1992 consists of one unit, generating 279 net MW. Shand Power Station is considered the cleanest and most efficient coal-fired power generating plant in Canada and in 1993, received a Power Plant Award from Power Magazine in recognition of its advanced environmental design. This design includes the LIFAC (Limestone Injection into the Furnace and reActivation of Calcium) system, which uses powdered limestone and water to remove SO2 emissions, and a closed-loop, zero-discharge water management system that ensures the water used in the plant will not be discharged into the environment, except through evaporation. The system also ensures finely tuned burner temperature and air quantity to reduce nitrogen oxide formations by up to 50%. The plant also features a high-efficiency electrostatic precipitator that collects up to 99% of the fly-ash before it leaves the station’s stack.

Hitachi Ltd. agreed to collaborate with Saskatchewan Power Corporation to jointly construct a Carbon Capture Test Facility in march 2012. The test facility will be a part of SaskPower's larger "Clean Coal Project", which is a comprehensive initiative to select and apply emerging carbon capture technologies to coal fired power plants to manage their emission of greenhouse gases. In this project equipment to capture CO2 will be installed at SaskPower's Shand Power Station. SaskPower and Hitachi will jointly invest 5 billion yen to cover the cost of the project. Operations of the CCTF will begin mid 2014.
