SaskPower and Cenovus Sign Agreement for Carbon Capture Project

LCG, January 30, 2013--SaskPower and Cenovus Energy executed a 10-year agreement for the purchase of carbon dioxide (CO2) produced from SaskPower?s carbon capture and storage (CCS) project at the Boundary Dam Power Station, near Estevan, Saskatchewan. Cenovus will purchase all of the CO2 captured - 1 million tonnes per year - and transport it to support enhanced oil recovery (EOR) activities near Weyburn, Saskatchewan.

The C$1.24 billion Boundary Dam Integrated Carbon Capture and Storage Demonstration project is currently under construction and scheduled to begin commercial operation on April 1, 2014.

Cenovus will need to construct a pipeline from the power plant to the oil fields, a distance of approximately 70 km. For ten years, Cenovus has been injecting CO2 into the Weyburn EOR field from the Dakota Gasification Corp. (DGC) plant located in Beulah, North Dakota. The new volume received from SaskPower will provide roughly 25 percent of the CO2 injected annually.

With the EOR market for CO2, SaskPower plans to increase its CO2 sales through the installation of additional carbon capture systems on other units.

The Government of Saskatchewan approved construction of the Boundary Dam Integrated CCS Demonstration Project in April 2011.

The existing Boundary Dam Power Station is SaskPower's largest power generating facility and includes six, coal-fired units, with a total plant generating capacity of 824 MW. Unit 3 will be rebuilt to incorporate a carbon capture process that will reduce capacity from about 139 MW to 110 MW, given expected energy loads for the carbon capture process. Cansolv, a wholly owned subsidiary of Shell Global Solutions, will supply the carbon capture process, and Hitachi will supply the steam turbine.
