SaskPower’s new 370-megawatt (MW) Great Plains Power Station has officially started generating electricity for Saskatchewan’s provincial grid. Located near Moose Jaw, the plant uses Siemens Energy’s advanced gas turbine and steam turbine technology, including the SGT6-5000F6.3 gas turbine, SGEN6-1000A generator, SST700-900 steam turbine, and SGEN6-100A steam turbine generator.
Construction on the plant began in March 2021, and by July 2023, more than 600 workers were involved at the peak of construction. Now operational, the Great Plains Power Station is run by a dedicated team of 25 full-time employees.
SaskPower’s EPC partner for the Great Plains project was Burns & McDonnell, which is also working on other key initiatives in the utility’s $1.6 billion modernization plan for the 2024-25 fiscal year. The plan includes several major investments to expand and enhance the province’s energy generation capacity.
In addition to the Great Plains Power Station, the modernization plan features the construction of the Aspen Power Station, a 370 MW natural gas combined-cycle (NGCC) plant expected to be online by Spring 2028. Burns & McDonnell is again the EPC partner for this project.
SaskPower is also expanding its existing facilities. The Ermine Power Station will add a simple-cycle natural gas turbine, producing an additional 46 MW of power, with the new turbine set to come online by May 2025. Similarly, the Yellowhead Power Station will add its fourth turbine, contributing another 46 MW, with the unit scheduled to be operational by December 2025.
The $1.6 billion modernization plan also includes grid maintenance and upgrades, smart meter deployments, and growth projects, representing an increase of $433 million over the previous year’s capital investment.
