Suncor Energy to invest $1.4 billion in low-carbon power cogeneration at its Oil Sands Base Plant

·Delivers superior returns and a significant contributor to the company’s goal of growing incremental free funds flow by $2 billion by 2023

·Suncor’s greenhouse gas (GHG) emissions associated with steam production at Base Plant will be reduced by approximately 25%

·GHG emissions in the province of Alberta will be reduced by approximately 2.5 megatonnes per year

Calgary, Alberta (Sept. 9, 2019) — Suncor today announced it is replacing its coke-fired boilers with two cogeneration units at its Oil Sands Base Plant. The cogeneration units will provide reliable steam generation required for Suncor’s extraction and upgrading operations and generate 800 megawatts (MW) of power. The power will be transmitted to Alberta’s grid, providing reliable, baseload, low-carbon power, equivalent to approximately 8% of Alberta’s current electricity demand. This project will increase demand for clean natural gas from Western Canada.

“This is a great example of how Suncor deploys capital in projects that are economically robust, sustainability minded and technologically progressive,” said Mark Little, president and chief executive officer. “This project generates economic value for Suncor shareholders and provides baseload, low-carbon power equivalent to displacing 550,000 cars from the road, approximately 15% of vehicles currently in the province of Alberta.”

The project cost is estimated to be $1.4 billion, delivering a high teens return and projected to be in-service in the second half of 2023. This project will substantially contribute to the company’s goal of an increased $2 billion in free funds flow by 2023. This will be achieved through Oil Sands operating cost and sustaining capital reductions along with margin improvements. It will also contribute materially to Suncor’s publicly announced GHG goal.

Replacing the coke-fired boilers with cogeneration will reduce GHG emissions associated with steam production at Base Plant by approximately 25%. It is also expected to reduce sulphur dioxide and nitrogen oxide emissions by approximately 45% and 15% respectively. The cogeneration units will eliminate the need for a flue gas desulphurization (FGD) unit, which is currently used to reduce sulphur emissions associated with coke fuel. Decommissioning the FGD unit will reduce the volume of water the company withdraws from the Athabasca River by approximately 20%.

By producing both industrial steam and electricity through a single natural gas-fuelled process, cogeneration is the most energy-efficient form of hydrocarbon-based power generation. Suncor believes this project will contribute to both Alberta and Canada’s climate ambitions.

Free funds flow is calculated by taking funds from operations (FFO) and subtracting capital expenditures, including capitalized interest.  Free funds flow and FFO are non-GAAP measures.  Non-GAAP measures do not have any standardized meaning under GAAP and therefore are unlikely to be comparable to similar measures presented by other companies and should not be considered in isolation.  See Non-GAAP Measures in the Q2 MDA for further information.
