Location: Estevan, SK
Fuel source: Coal
Net capacity: 276 MW
- One unit with a generating capacity of 276-net MW.
- Received a Power Plant Award from Power Magazine in 1993 in recognition of Shand’s advanced environmental design.
Advanced Environmental Design
- The LIFAC (Limestone Injection into the Furnace and re-Activation of Calcium) system, which uses powdered limestone (sorbent) and water to remove sulphur dioxide emissions
- The finely-tuned burner temperature and air quantity reduces nitrogen oxide formations by up to 50 per cent. Nitrogen oxide contributes to acid rain and smog.
- A closed-loop, zero-discharge water management system ensures the water used will not be discharged into the environment, except through evaporation.
- A high-efficiency electro-static precipitator (ESP), which acts as a giant dust collector to trap over 99 per cent of the fly ash before it leaves the power station’s stack.
- A state-of-the-art computer control system that ensures the station runs as efficiently as possible.

The high-pressure steam is directed into a turbine, which turns the turbine shaft. This shaft, connected to an electrical generator, produces electricity as it turns.
A condenser converts the spent steam from the turbine back to water that is reused in the boiler. The condenser cooling water comes from the reservoir and is returned for reuse.
