Rehabilitation of HPP Letten in Sweden

Končar – Generators and Motors, Inc. successfully started 2021 by contracting the rehabilitation of the G2 generator (22,5 MVA, 11 kV, 500 rpm) at HPP Letten.

The tender and contracting process was very short due to the G2 generator breakdown which expedited the start of repair process. The contract was signed in January 2021. The scope of work includes finishing the existing housing and installation of a new stator core and coils, re-insulation of poles, a new generator cooling system, refurbishment of bearings, on-site installation, testing and commissioning.

Realization deadlines are very short and commissioning is expected in the first half of August 2021.
