The upgraded Enerdu Generating Station is now operating in Almonte, Ontario, Canada, and the redevelopment work increased its generating capacity by 70%.
A grand opening celebration was held Feb. 27.
According to an announcement from the Ontario Waterpower Association, Enerdu Power Systems Inc. constructed a new powerhouse to “maximize the waterpower potential of the Mississippi River at Almonte.” The new powerhouse was needed to accommodate two larger axial-flow Kaplan pit turbines, each with a capacity of 500 kW.
“Enerdu Power Systems is to be commended for the completion of this project,” said Paul Norris, OWA president. “This is a great example of the opportunities that exist across the province to expand the contribution of waterpower to provide economic, environmental and reliable energy benefits for present and future generations.”
Enerdu says the total budget for this project exceeded $10 million. All civil work was awarded to local companies, including Thomas Cavanagh Construction. The design of the new building was created working with The Ventin Group.
The new inflatable weirs that form part of the run-of-river project will add to the Mississippi Valley Conservation Authorities toolbox to deal with flood waters, Enerdu says. In addition, the new plant will provide the first upstream and downstream American eel migration methodologies on the Mississippi River.
Canadian Hydro Components provided water-to-wire equipment for the project. OWA says the generators were custom-designed to connect directly to the turbine shaft using the pit wall as the generator shell. This arrangement eliminates the need for gearbox connection and provides better efficiency while decreasing costs, OWA says.
In other recent news in Ontario, HydroWorld recently reported that the owner of the 10-MW Namewaminikan Waterpower Project was issued fines in two separate matters.
