Hydroelectric developments

Island Falls

The only operating hydroelectric generating station on the Churchill River is Island Falls, with a capacity of 111

megawatt The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantify the rate of energy transfer. The watt is named after James ...

s (MW). The purpose of the Whitesand Dam mentioned above is to control the amount of water flowing through Island Falls, since the generating station is downstream of the Reindeer River fork.

Wintego Hydroelectric Project

In the 1970s, SaskPower was considering building another hydroelectric station on the Churchill River called Wintego. This station would've been located downstream of the Reindeer River forks, and upstream of Island Falls. The project was expected to cost $338 million (equivalent to $1.3 billion in 2020), including transmission and roads, and the capacity of the station would have been 300 MW. The cost estimate assumes a 50-year lifespan, but the lifespans of SaskPower's other hydroelectric stations have been proven to be much longer (such as 90 years for Island Falls). Construction of Wintego would also enable the output of Island Falls to increase by 70 MW, and this benefit is not included in the cost estimate above.

Other Saskatchewan

Two other potential hydroelectric developments between the Reindeer River Fork and Island Falls are the Iskwatam Generating Station and the Pita Generating Station, with unknown MW capacities.

Manitoba

In Manitoba, the Bonald and Granville Falls generating stations could produce 110 MW and 120 MW, respectively.
