PROJECT

Great Plains Power Station

We were the engineer-procure-construct (EPC) partner for the 370-megawatt (MW) Great Plains Power Station, a combined-cycle, natural gas-fired thermal electric generating facility supplying reliable, cost-effective baseload power to the province of Saskatchewan, supporting local and regional growth.

Brought online in 2024, the facility features a single gas turbine generator, a triple pressure heat recovery steam generator (HRSG), an air-cooled condenser and two generator step-up transformers. Other plant components include a new switchyard connecting to an existing transmission line and a building that combines water treatment, maintenance, warehousing and administrative functions.

The project contributes to SaskPower’s goal of achieving a net zero greenhouse gas (GHG) emissions power system by 2050. The combined-cycle model uses the most efficient technology and is held to stricter emission regulations than other plants.

This is the third in a series of projects we have brought online for SaskPower, with a fourth — Aspen Generating Station — in design and early construction.

Design and Construction Challenges

The extreme temperatures of the region meant much of the piping was buried 2.5 meters to 2.8 meters below the surface, providing added insulation to prevent waste and wastewater from freezing. Plant wastewater is routed to the city of Moose Jaw’s wastewater lagoons adjacent to the facility.

To facilitate an efficient on-site construction schedule, a number of plant components — including the demineralized water storage tank and HRSG stair tower and stack — were fabricated and assembled off-site and shipped to the project site in larger units.

Commitment to Community

During construction, about $60 million in additional revenue was generated for Saskatchewan businesses, with 35 jobs created from the provision of services to the plant and spending of plant employees.

Throughout every phase of the project, we worked with SaskPower to prioritize the hiring of local and/or Indigenous firms and other local labor. As of early 2025, more than 300 Saskatchewan companies contributed to the project, for a total of $332.9 million Canadian in local participation and $49.6 million Canadian in Indigenous participation. At the peak of construction, more than 700 workers were on-site each day. Overall, 70% of workers were from Saskatchewan, including 13% from Moose Jaw.

The plant is operated by 25 full-time, on-site employees.
