Norway generator Ringeriks-Kraft Produksjon AS invites separate applications for pre-qualification to supply a turbine, a generator, and construction of a new powerhouse at the 19-MW Vittingfoss hydroelectric project. Responses are due June 27.
Ringeriks-Kraft issued a similar solicitation in 2008. It recruited a designer in 2007 for at least one Kaplan turbine-generator set for Vittingfoss.
The firm has a site license to add a new Unit 5 of between 8 and 16 MW at the run-of-river plant in Buskerud County. It said it plans a new surface powerhouse for an expansion at the side of the existing powerhouse.
In one solicitation, it seeks a vertical Kaplan turbine designed for a head of 19.5 meters and total flow of 65 to 80 cubic meters per second. Estimated value is between 25 million and 35 million kroner (US$4.68 million and US$6.5 million).
In a second solicitation, it seeks a three-phase 50-Hz generator to be directly run by the turbine. That contract’s estimated value is between 25 million and 30 million kroner (US$4.68 million and US$5.6 million).
In a third solicitation, it seeks a new powerhouse alongside the existing plant. Work is to include demolition of the existing dam and concrete works in connection with a new dam. That contract’s estimated value is between 35 million and 50 million kroner (US$6.5 million and US$9.3 million).
Documents for each solicitation may be obtained from the address below.
