Norway Has Discovered Wind Wind Power at the Arctic Sea The 16 turbines with a total output of 40 MW mark a turning point in the country’s energy industry. They will be producing 120 gigawatts of clean electricity each year in attempt to address the problems that Norway is experiencing in ensuring secure supplies of electricity. Formerly a major exporter of hydroelectricity, the country is now consuming almost as much electricity as it is producing. Thus, in 2000, it used 125.5 terrawatthours. By contrast, it produced some 142.2 TWh of hydroelectricity, accounting for 99 % of total electricity output. Thermal power stations contributed a sizeable 731 GWh, while wind power remained on the sidelines, contributing only 30 GWh. 8 In Havøysund, Norway’s largest wind farm to date has gone into operation. WINDPOWERUPDATE ı Europe The Nordex 40 MW wind farm at Havøygavlen. “I am pleased that the community of Måsøy is now also generating energy”, says Ingalill Olsen. “Finnmark is the coldest region in Norway but only covers 15 % of its own energy requirements”. The town mayor is sitting in her office opposite the port. From her window, the 287 meter high Havøygavlen, home to the new turbines, can be seen.
The wind farm starts five kilometres above the port facilities. All of Havøysund’s five roads used to end at the town’s last houses. Now, there is a gravel road leading up the hill behind the cemetery. The dark stone is covered only by moss and lichen. The 16 turbines operate at altitudes of between 250 and 280 metres, with the 80 metre high towers providing a fantastic view across the Arctic Sea. Havøygavlen lies at the end of the world, which is why Nordex has fitted the 2.5 MW turbines with a power crane system; a special facility developed for offshore use. In this way, all main components can be replaced without the need for an external crane, allowing time to be saved and doing away with the need to transport heavy equipment. Ingalill Olsen has been observing the construction work from her desk since April 2, 2002. The most important woman in the town watched the 11 kilometre network arising on the hill. She also heard the explosions when holes were dug in the naked stone of the hill for the 16 base elements, each one three metres deep and ten metres in diameter. She watched the heavy transporters and the Caterpillar lug the individual turbine parts up the mountain and technicians from Denmark and Germany assemble the turbines as quickly as possible under the midnight sun. The wind turbines have been watching over the fishing village since August 22. The 21 Måsøy town elders were unanimously in favor of constructing the wind farm – not only because it created a number of long-term jobs but also because they all realized the advantages of “good energy”. “This location offers decisive advantages over other places,” says Ingalill Olsen. In addition to our port and the support on the part of our population, reindeer play a key role in this region, wandering between the summer fields along the coast and the winter locations in the interior. However, as there are no reindeer on the island of Havøya, negotiations with the locals were not necessary. The wind farm generates enough electricity for 6,000 households. In Germany, this volume of electricity would be sufficient for seven times as many households. However, no other country in the world consumes as much electricity per capita as Norway. And nowhere is this truer than in Finnmark. In fact, Ingalill Olsen alone needs around 28,000 KWh per year. The country’s energy ministry is expecting a further increase in consumption. For this reason, parliament passed a bill in March 2001 providing for the establishment of a state energy agency. Its duties will include revising energy policy, promoting regenerative sources of energy and implementing measures to ensure more efficient use of energy. Known as Enova, it commenced its operations in January 2002. At this stage, Norway had 28 wind turbines with an output totalling 17 MW. The Havøygavlen wind park is a decisive step towards reaching the national goal of generating 3 TWh from wind power by 2010. A further five projects with total annual output of 605 GWh have already been approved. “We consider the target to be realistic and are sure that we will achieve it by 2010,” says Dr. ing. Magnar Førde, director of regenerative energy at Enova. The world’s northern-most wind farm is a reference project for both Norway and for Nordex, which assembled the 16 turbines on a turn-key basis for operator Arctic wind, a joint venture forged by Norway’s largest industrial group Norsk Hydro and Dutch utility Nuon as well as the planning agency Norsk Beautiful view from the top of one of the Havøygavlen turbines. Miljøkraft. Enova contributed 3 8 million to the 3 40 million project. “This wind farm marks the entry to an interesting new market for us,” says Dietmar Kestner, CEO at Nordex AG. Nordex is now also engaged in negotiations with Norsk Miljøkraft concerning a 200 MW wind farm 500 km south of Havøysund. “Conditions here on the coast are ideal for our N80 turbines,” says Tage Christensen, project manager at Nordex. The climate is moderate thanks to the Gulf stream, with winter temperatures rarely dropping below minus 26 degrees Celsius. On the other hand, there is a steady wind with an average annual speed of 9 metres per second. If the wind speed exceeds 25 m/sec, the turbines automatically disengage. Although construction work was interrupted for five days due to a gale twice this speed, the 40-year old mechanical engineer sitting in his office container at the port says that this was an exception. “This project is also a test for our offshore units.” Looking forward, Nordex also wants to assemble the N80, the world’s largest series turbine, in offshore locations.
