Norway’s biggest power producer, Statkraft SF, has awarded the largest turbine upgrade contract in the company’s history to GE Hydro, a unit of GE Power Systems, for the refurbishment of five hydropower plants.
The project is said to cover 770 megawatts of capacity and is valued at $11.9 million.
According to GE, this is the most extensive turbine modernisation project to date for the Oslo-based Statkraft, which owns about 30 percent of the country’s electric power production capacity, all of which is hydro-based.
Under the terms of the contract, GE will upgrade and refurbish a total of 10 Pelton turbines at Statkraft’s Aura North, Aura South, Hoyanger, Mauranger and Mar hydropower plants.
The turbines are said to include both horizontal and vertical units, all manufactured by other OEMs. The project scope includes the design, model testing, engineering, installation and commissioning of new runners and refurbishment of existing parts. Efficiency improvements from the upgrades are expected to range from one to three percent at maximum output.
The turbine runners for the project will be manufactured at GE’s Norway production facility. Using a newly developed GE technology, the runners will be made from solid, rather than traditional cast, forgings to improve the accuracy and fatigue strength of these core turbine components.
Equipment for the project is expected to begin shipping in mid-year of 2003 and will continue through to 2005.
