L&S Electric (L&S) was selected by the City of Thief River Falls, Minnesota, to rehabilitate and upgrade the unit number two generator after it was damaged by a fire. The rehabilitation work included supplying a new unit turbine shaft, rehabilitating the turbine bearings, and rewinding the generator.

The L&S team works to remove the runner.

The upgrade portion of the project provided new plant protective relaying, a new unit automation system, a new unit governor with a new high-pressure hydraulic power unit (HPU), a new unit exciter, and new unit protective relaying. The rehabilitation and upgrade services were provided on a turnkey basis.

On its way to get rewound, the generator stator is loaded onto a truck.

The unit number two rehabilitation and upgrade project required the talents of multiple L&S divisions, including the Onsite Services division, the Power Services division, the Large Motor Repair division, and the Power Control Solutions division. In addition to the L&S team, the project also utilized the services of two subcontractors.

The rebuilt runner is installed.
