Test production is under way on the first two of three generating units being installed at the new 270-MW Sonna hydroelectric project in Norway.
Norwegian metals producer Elkem Saudefaldene named Alstom in 2005 to supply two 120-megavolt-ampere generators and one 70-MVa generator for the plant. Additionally, Alstom is to supply instrumentation, controls, and balance of plant.
Alstom completed installation and began test production of the two 120-MVa units in June. The 70-MVa unit is to begin testing in early August, project manager Harald Kjetil Glendrange said.
The new three-unit plant replaces an existing plant, increasing generating capacity by 240 MVA and 210 MW. Glendrange said the project’s new intakes create higher heads and increase production by about 500 gigawatt-hours a year.
