We're at Minnesota Power's hydroelectric dam in Scanlon, Minnesota, to replace 7 of the structure's Tainter gates. Extending the life of this renewable energy source by 50 to 100 years, the Scanlon Dam Gate Replacement Project enables the further creation of clean, renewable power provided to local communities. 

We were pulled into the project very early on during the design phase of the project. Both Nelosca and Minnesota Power attribute the project's success to early contractor involvement.

At Nelosca, we work on dams of various sizes and functions. Very few new dams are built each year, so most of our work consists of rehabilitation and repairs. Dams are built to last for long periods of time, however certain components require periodic repairs and replacements. Radial gates, often referred to as Tainter gates, consist of components most commonly in need of attention. In our experience, we have found certain best practices that will increase the longevity of these gates, as well as increase their functionality.
