New Hydroelectric Projects
Hydroelectricity has been the driver of Ontario's economy for much of the 20th century, providing the province with the power it needs to grow. Ontario still has considerable hydroelectric resources that can be developed, and OPG is working to develop those resources in a safe and environmentally responsible manner.
The newly completed Niagara Tunnel is a major initiative on the road to this goal. The tunnel will annually produce more power, on average, than cities the size of Niagara Falls or Kingston use every year. With minimal maintenance costs, all this energy will be generated year-in, year-out for a hundred years or more.
The new 12 MW Lac Seul Generating Station was recently completed. Built adjacent to an existing facility - the Ear Falls Generating Station - Lac Seul captures the water that is spilled past the existing station to maximize the use of the available water resources at the site.
As well, OPG recently redeveloped three generating stations located on the Upper Mattagami River and one on the Montreal River in Northern Ontario. The combined capacity of 35 MW at the new stations is an increase of 45 per cent from the old generating stations.
OPG is currently working on the Environmental Assessment for the Little Jackfish project in Northwestern Ontario. It is planned to generate up to 75 MW of new power for Ontario.
OPG has also proposed the expansion of the Ranney Falls Generating Station on the Trent Severn Waterway, in Northumberland County. The project will double the stationís current capacity, and generate up to 20 MW of clean power for Ontario.
In addition to these projects, there are a number of other projects in different phases of development. The most notable of these is the Lower Mattagami project, which is currently under construction. At the completion of the project, OPG will add another 438 MW of hydroelectric capacity to Ontario's electricity system.
