Rainpower - large hydro reference projects

Rainpower´s Large Hydro Reference Projects

Rainpower is a supplier to a number of large projects; here is a selection:

France

EdF Energy, France

tinee

Rainpower has entered into an agreement with the international energy group EDF Energy for a study of hydraulic systems, and delivery of two refurbished turbines for the Courbaisse power plant. This is phase two of the Tinée power plant, located near Plan du Var, north of Nice. The river power plant has a capacity today of 25.5 MW. The project is particularly important because it opens up for Rainpower in the French refurbishment market.

Switzerland

Robiei, Switzerland

ofima2

Rainpower has entered into an angreement with the Swiss energy producer Ofima for delivery of equipment for the Robiei power plant. The contract comprises pump turbines and a Francis turbine with equipment; replacement of the electro mechanical equipment at the plant, as well as four reversible pump turbines adjusted to a head between 284 and 395 metres, with maximum effect of 41 MW. One Francis turbine is adapted to a head between 270 and 390 metres, with maximum effect of 27 MW. The deliveries include inlet and outlet valves, as well as oil pressure systems. Due to the large variations in head, Rainpower will perform model testing of two different turbine runners. The project will be carried out by by a consortium with Alsthom in Switzerland, which will deliver the generators/motors and the inlet valves for the pump turbines.

Bavona, Switzerland

bavona_loepehjul

One of our large international projects is the refurbishment of Bavona power plant, owned by Ofima, Switzerland. Rainpower will deliver two double horizontal Pelton turbines (each 41.3 MW); these are of the world´s largest of their kind. The delivery comprises ball valve, inlet valve, model test in our Trondheim laboratory, turbine regulator with oil pressure system, cooling system, assembly management, training and commissioning. Alstom is Rainpower´s supplier of generators.

Norway

Svartisen Generator 1 Project, Norway

svartisen

Rainpower delivers Svartisen aggregat 1 for Statkraft Energi AS. The power plant is located near the glacier Svartisen, in Nordland county. Rainpower delivers complete turbine, main valve and turbine governor. The turbine´s effect is 250 MW. This is one of the largest hydropower developments in Norway during recent years. The upgraded power plant will make use of existing waterway of Generator 2, which was delivered by Kværner in 1993. Rainpower is also delivering a new 350 MW turbine runner for Generator 1, model tested at the Trondheim laboratory.

Aurland III, Norway

stolsvatn

The power plant Aurland III, owned by ECO Vannkraft, started production in 1979. Aurland III is a reservoir and pumped storage power plant with an approximate head of 400 metres, and installed capacity of 270 MW. The power plant has two pump turbines, and an average annual production of 281 GWh. Rainpower delivers a complete reversible pump tubine with valve guidance and governor for oil pressure system for Aurland III, turbine No. 1.

Øljusjøen power station, Norway

Rainpower has refurbished the Øljusjøen power station for Østfold Energi AS. The power station consists of a single pump turbine of 48.5 MW with a fall of 220 m. The pump capacity is on the 17.5 m3 per second, with a 205 m head. In addition to a new turbine runner, Rainpower also supplied slit rings, oil pressure system and the main servo motor. The project started in December 2006 and was completed in December 2008.

Nedre Vinstra power station, Norway

Rainpower upgraded Lower Vinstra power plants from 50 to 65 MW for Eidsiva Hydropower AS. Rainpower has delivered a new turbine runner, turbine shaft, bearing, tetningsboks, lid, lead device, sugerørskonus and new turbine governor. Delivered in September 2008.

Rendalen 2, Norway

For the new power station in Rendalen, which will replace the existing station, Rainpower will deliver the turbine and the pressure shaft and associated parts. The customer is Eidsiva Hydropower AS. The power station will be built inside the mountain in the immediate vicinity of the existing Rendalen power station, which was completed in 1971. The water is transferred via a 29 km long transfer tunnel between Glomma by Høyegga and Northern Rena river at Lomnessjøen. The turbine produces 100 MW, with a head of 185m, and in addition to this Rainpower will deliver the main valve, turbine governor, installation and commissioning. For the waterway Rainpower will supply 140 metres of penstock, with a diameter of 3.8 metres, butterfly, straws hatch, cross sport and valve in the clear chamber with tubes. The delivery will be completed in October 2012.

Hol 1 Power Station, Norway

Rainpower will upgrade the four Francis turbines with ancillary equipment in Hol 1 power plant, which is owned by E-CO Vannkraft AS. Unit 1 and 2 are each of 57 MW, with a head of 396 meters; units 3 and 4 are each of 53 MW with a head of 355 meters. In addition to the new turbine runners, Rainpower will also deliver four new safety valves, four main valves with the current, four new oil pressure system and four new turbine governors. The project started in November 2007, and is planned to be completed in November 2012.
