Efacec Energia of Portugal has been awarded a contract worth $19 million to supply generator step-up transformers for the 270 MW Burfell hydroelectric project on the Thjorsa River in southern Iceland.
Icelandic utility Landsvirkjun solicited bids for the work in February 2013. Per the award, Efacec Energia will supply three identical single-phase power transformers to act as a generator step-up transformer bank for Burfell Units 1 and 2.
Landsvirkjun awarded a contract in 1998 to ABB Asea Brown Boveri AB of Sweden to refurbish electrical equipment at Burfell, which supplies one-third of the power for Iceland’s national grid. Modernization at Burfell began in 1996-1997 with installation by Sulzer Hydro of six new Francis turbines.
The utility took bids in 2003 for the Nordlingaalda River Diversion to divert additional water through Burfell and five other hydroelectric projects. It took bids last year for generator step-up transformers for another one of those plants, 80 MW Budarhals on the Tungnaa and Kaldakvisl rivers.
