Facts about the Boundary Dam Power Station
- In 1959, Unit #1 (62 MW) and Unit #2 (61 MW) produced a total of 123 MW.
- The next 2 units were added in 1970. They had a combined capacity of 278 MW.
- Unit #5 was added in 1973 and created 139 MW.
- The final unit, was added in 1978, generating 284 MW of power.
- To clean the emissions from the smokestacks, we installed a dry scrubber on all units. It traps over 99% of the fly ash. Helping to remove harmful pollutants before it ever leaves the power station's smokestacks. This long-term project finished in July 2003.
- Units #1 and #2 retired from service in 2013 and 2014. This was because of federal rules on carbon dioxide (CO2) emissions.
Carbon Capture and Storage (CCS)
In 2014, the Boundary Dam Carbon Capture Project transformed the energy landscape. The Power Station near Estevan, Saskatchewan, turned Unit #3 into a reliable 120 MW producer of base-load power.
CCS technology can reduce up to 90% of greenhouse gas emissions from Unit 3. Since operations began, CCS prevented more than 4-million tonnes of CO2 entering the atmosphere. That's equal to taking 1-million vehicles off the road for a year.
