Iceland utility Landsvirkjun plans to seek bids by August for consulting engineering work to help develop three hydroelectric projects on the lower Thjorsa River.
Landsvirkjun said it plans to seek tender design and preparation of tender documents, and possibly detail design and construction supervision for civil and electro-mechanical contracts of the three projects to be built downstream from the 270-MW Burfell hydro project in southern Iceland.
The three run-of-river projects include:
o Hvammur, 75 MW, including three kilometers of waterways, a concrete weir, 3.5-kilometer dyke, and a shaft-type powerhouse containing a 75-MW vertical Francis or Kaplan turbine. The plant would have a maximum flow of 300 cubic meters per second, a head of 32 meters, and average annual generation of 620 gigawatt-hours;
o Holt, described as a second stage of the Hvammur development, featuring short artificial waterways, an intake pond, and a powerhouse with two vertical Kaplan turbines of unspecified megawatts. It would have a maximum flow of 310 cms, a head of 18 meters, and average annual generation of 390 GWh;
o Urridafoss, 120 MW, including a 4.3-kilometer dyke and reservoir, short underground penstocks, 3-kilometer tailrace tunnel, and an underground powerhouse with two vertical Kaplan units. It would have a design flow of 320 cms, a head of 42 meters, and average annual generation of 960 GWh.
Landsvirkjun said it plans to open tenders in August, with work to be carried out between 2006 and 2010.
