Why SaskPower reported two completion percentages for Aspen Power Station

Overall progress includes engineering and procurement

On 1 July 2025 SaskPower put construction at about 20% and the overall project at 42%. The operator describes the overall measure as including the procurement and engineering portions. Components can be designed, contracted or delivered before construction crews finish putting them in place. Source 1

Equipment deliveries preceded substantial site completion

By February 2026 engineering was reported 95% complete, 93% of procurements had been awarded and 95% of materials and equipment had arrived at the site. Construction stood at 44%, with mechanical and electrical work still underway. The different percentages describe different work and use their own denominators. Source 1

The gap narrowed by the end of July

At 31 July 2026 the operator put construction at 82% and overall progress at 88%, a six point difference compared with about 22 points in July 2025. It separately reported 2.8 million work hours on site and more than C$589 million awarded to Saskatchewan companies. Awards are contracts and do not by themselves show cash paid to date. Source 1

The plant and connection are part of the delivery scope

SaskPower describes a 370 MW natural gas station near Lanigan with a new 230 kV connection about three kilometres long to the existing Wolverine switching station. Its project page targets operation in 2027. The construction figures track progress before the target in-service date and cannot establish how much electricity the plant has supplied.
