The Bighorn Plant is one of the highest performing hydro plants in Alberta, producing an average of 408,000 megawatt hours each year. The site has required significant upgrades and expansion over the years. Rising Edge provided engineering, construction, and commissioning services. Rising Edge moved all protection and control equipment from the generating plant to the substation. Additional scope included the expansion of the substation to accommodate a new control building as well as major equipment additions and replacements. All outdoor cabling was also replaced. In order to minimize the environmental impact of reduced river flow in the North Saskatchewan River, Rising Edge was able to complete all transfers and cutovers within two (2), 24-hour Plant outages.
