Swedish firm wins civil rehab of 3.7-MW Ludvika

Swedish generator Vasterbergslagens Kraft AB (VB Kraft) has awarded a 27.1 million kronor (US$3.8 million) contract for civil works refurbishment of the 3.7-MW Ludvika hydroelectric project.

VB Kraft awarded the contract to AEB Anlaggningsentreprenader Hogtryck AB of Sweden, the sole bidder for the work at Ludvika, 240 kilometers from Stockholm.

The board of VB Kraft decided in 2005 to invest US$8 million in refurbishment of Ludvika, which was built in 1901. (HNN 12/29/05) The full project is to include replacement of machines built in 1930 and 1941, reinforcement of a masonry headrace tunnel, and installation of new penstock, controls, electrical and cooling equipment, and gates.

The work is to reinforce the existing tunnel and boost efficiency, increasing annual production to 13 gigawatt-hours from 10 GWh. Reservoir levels and discharge will remain the same as stipulated in the project’s original permit.
