The Project involves the replacement of three aging petroleum coke-fired boilers with two highly efficient natural gas cogeneration units. The use of cogeneration will generate approximately 800 megawatts (MW) of reliable, low cost, low-carbon power to the Alberta Interconnected Electrical System.
The Coke Boiler Replacement Project is located at Suncor’s Oil Sands Base Plant, 25 kilometres north of the city of Fort McMurray, Alberta.
The figure below identifies the location of the project.
Regulator (AER) applications were filed in January 2018. Suncor received key approvals from the AER in July 2018 and from the Alberta Electric System Operator (AESO) in November 2018. Alberta Utilities Commission (AUC) approvals were received in March 2019. The project was sanctioned in September 2019. Suncor will continue to be engaged with all required regulatory agencies as the Project proceeds into construction. Construction is targeted to begin in the fall of 2019, with commissioning of the cogeneration units expected by 2023.

- Existing coke-fired steam generation boilers at Suncor’s Base Plant provide a large portion of the steam requirements within the Suncor oil sands operations. This project will involve replacing these boilers with modern, highly efficient, natural gas-fired cogeneration technology, which generates two products: low-carbon electricity (which the province requires to meet its stated climate goals) and steam (which Suncor requires to supply its Base Plant operations).
- The project will generate approximately 800 MW of additional reliable, low cost, low carbon intensity power to be exported to the Alberta Interconnected Electrical System.
- Suncor is primarily focused on ensuring reliable steam supply for its facilities, but believes that implementing cogeneration is the most cost and carbon efficient method of producing both steam and power to meet demands.
- Because of the 24/7 nature of our Base Plant operations, this is expected to provide a reliable and stable power source.
- The Coke Boiler Replacement Project has the potential to make a measurable environmental contribution in support of the provincial and national climate change strategy. The Project is expected to reduce our air emissions, including sulphur dioxide and nitrogen oxides, as well as net water intake.
Cogeneration produces heat energy using natural gas, which would replace the petroleum coke fuel, with the added benefit of producing electricity. Suncor’s systems are designed to fulfill its facility electrical demands first, and then deliver any excess power to Alberta’s Interconnected Electrical System.
The excess power we would supply to the grid is expected to benefit the province as it is a by-product and is produced at a low cost. This project is well positioned to contribute towards Alberta’s transition away from coal and towards more sustainable energy sources.
Our goal:
- Community and stakeholder engagement is a key component of the Coke Boiler Replacement Project and we will continue to work closely with stakeholders throughout the project.
- This includes Indigenous communities in the Regional Municipality of Wood Buffalo. Throughout this engagement process, Suncor seeks to build effective, long-term and mutually beneficial relationships.
Throughout construction, Suncor representatives will continue to share information with RMWB communities in support of our regulatory obligations. Ongoing engagement will continue during start-up and commissioning.
- net water intake,
- GHG emissions, and
- other air emissions, including sulphur dioxide, nitrogen oxides and particulate matter.
Suncor will continue to engage with local stakeholders. Our project development plan reflects input provided by stakeholders including regulators and local Indigenous communities.
Consistent with Suncor’s commitment to continued investment in the region, this project may also:
- create employment opportunities
- promote economic growth and business development
- provide valuable revenues for governments
- increase access to education and training
- enhance community investment
