Location: Estevan, SK
Fuel source: Coal, Coal with CCS
Net capacity: 672 MW
- The first two units (with Unit #1 having 62 and Unit #2 having 61 net MW) were commissioned in 1959.
- The next two units (with a combined generating capacity of 278 MW) were added in 1970.
- The following unit (with a generating capacity of 139 MW) was added in 1973.
- The final unit (with a generating capacity of 284 MW) was added in 1978.
- A long-term project to install electrostatic precipitators on all units — to reduce air particulate emissions — was completed in July 2003.
- Due to federal regulations related to CO2 emissions standards, Units 1 and 2 were retired in 2013 and 2014, respectively.
Carbon Capture (CCS)
Completed in 2014, the Boundary Dam Carbon Capture Project has transformed the aging Unit #3 at Boundary Dam Power Station near Estevan, Saskatchewan into a reliable, long-term producer of 120 megawatts (MW) of base-load electricity and can reduce greenhouse gas emissions by up to one million tonnes of carbon dioxide (CO2) each year. That’s equivalent to taking more than 250,000 cars off Saskatchewan roads annually.

The high-pressure steam is directed into a turbine, which turns the turbine shaft. This shaft, connected to an electrical generator, produces electricity as it turns.
A condenser converts the spent steam from the turbine back to water that is reused in the boiler. The condenser cooling water comes from the reservoir and is returned for reuse.
