Boundary Dam Carbon Capture Project


In the fall of 2014, Boundary Dam Power Station near Estevan, SK, became the first power station in the world to successfully use Carbon Capture and Storage (CCS) technology.

Boundary Dam Unit#3 CCS at a glance...

  • Produces 115 megawatts (MW) of power—enough to power about 100,000 Saskatchewan homes.
  • Capable of reducing the SO2 emissions from the coal process by up to 100 per cent and the CO2 by up to 90 per cent.

Why Carbon capture and storage on coal

Coal is still the most widely used power source in the world, making up about 40 per cent of the world’s electricity. Saskatchewan has lots of coal. It’s cheap to use and coal plants are very reliable. However, burning coal also creates harmful C02 emissions.

SaskPower is increasing our use of natural gas, hydro, wind and solar. But these power sources together can’t replace coal overnight. As we increase these other power sources, we still need a constant power source that keeps the lights on 24/7 and is affordable for our customers. We also need to do all of this while renewing our aging infrastructure.

By capturing and safely storing CO2 emissions before they reach the atmosphere, we can help ensure a brighter future for both our province and the world.
