All of these developments would require a large increase in electric power exports, since
Manitoba load growth will not require this capacity for a generation or more. All of these projects require additional HVDC transmission capacity from the North to the South. One such project, Bipole III, had been discussed with communities on the east side of Lake Winnipeg, but this area has been reserved by the provincial government, making transmission line construction infeasible. The government and Manitoba Hydro have currently rerouted Bipole III through the west side of Manitoba and construction has begun as of 2012.

This causes South Indian Lake to rise 3 metres (10 feet), as opposed to the 10.6 metres (35 feet) envisioned in the original plan.

Although development of the Nelson River system was intended to secure a reliable source of low-cost energy to promote industrial development in
Manitoba, such development was not forthcoming. Concerns about the magnitude and cost of Hydro development led the provincial government to start an inquiry

More than 5000 MW of hydroelectric potential could be developed in
Manitoba, which includes 1380 MW at the Conawapa site, 630 MW at the Keeyask site, and 1000 MW at the Gillam Island site, all on the lower Nelson river. Other sites have been assessed but are not currently under study for development.

Manitoba. Jointly harnessing the water increased the flow of the Nelson River by 40%, while the flow of the Burntwood River is now 9

Several sites on the Nelson River, with potential of millions of horsepower, had been identified as early as 1911, but transmission of power to population centres in the south was beyond the state of the art of electric power transmission at that time. Between 1955 and 1960, studies were carried out

Churchill River diversion project was set into operation. Flow was diverted by a series of channels and control structures into the Nelson River. Instead of developing hydroelectric sites along the Churchill River, water was diverted by control structures and an artificial channel into
