Boundary Dam Integrated CCS Project

The Boundary Dam carbon capture project is operated by SaskPower at Unit 3 of the Boundary Dam coal-fired power station near Estevan, Saskatchewan, Canada. The project retrofitted the existing generating unit with post-combustion carbon capture technology to capture CO₂ from flue gas before release to the atmosphere. The capture system is designed to process emissions from a rebuilt 110 to 115 MW generating unit and capture up to 1 million tonnes of CO₂ per year. Captured CO₂ is compressed and transported by pipeline primarily for enhanced oil recovery, with excess volumes injected into deep saline formations for permanent geological storage. Commercial CO₂ injection began in 2014, making Boundary Dam the world’s first full-scale coal power plant with integrated CCS in continuous operation. The project was developed as a large-scale demonstration to validate long-term performance, reliability, and economics of CCS on coal generation. The total project cost was approximately $1.24 billion, funded through a combination of $240 million from the Government of Canada and about $1 billion from SaskPower, Saskatchewan’s provincially owned utility. Boundary Dam continues to operate as a reference facility for utility-scale post-combustion carbon capture deployment
