Wear and tear, sand, bugs, strikes of lightning and not to mention winter itself all affect the need for blade maintenance. Experts in the field say it has to be done on a yearly basis, but that is not always the reality. The Finnish company Bladefence is curing...

Uncertain electricity supply, undeveloped infrastructure and a loss of profit due to icing. These are all factors which may lower the availability of loans for wind energy in cold climates. – “We need proven technology”, says a Swedish bank. Swedish bank Nordea...

On February the 13th we will have a guided tour 07.30-15.00 to the wind farm Mörttjärnberget, located in Bracke municipality, southeast of Östersund. The wind farm with 37 wind turbines will have an installed capacity of 100 MW and an annual production electricity of...

The wind park Blaiken is one of four Swedish projects nominated for support from the EU NER300-program, one of the world’s largest programs providing funding for renewable energy. - “A support can mean a big step forward for the development of wind energy in cold...

Surrounded by mist, ice-cold air and blue light, as the temperature declines a thin layer of frost is slowly building up on the transformer. It is subjected to a simulated winter, closely observed and subsequently analyzed. A newly built climate chamber will help wind...

The veteran Jos Beurskens is challenging the Swedish wind power industry: Devise your own technical solutions instead of waiting for the big industrial players to grasp the potential of cold climate wind energy.  But, he emphasises, don’t forget to look beyond low...

A Retrospective Overview Of Wind Farms In Cold Climate Regions Challenges Of Cost Effectiveness Wind energy in cold climate regions (WECC) stands at the threshold of major research and development trends within onshore & offshore wind energy. It is actively...

Put simply, blade heating on wind turbines is cost effective. That is the result of last year’s study at the Uljabuouda wind farm in northern Sweden. The tests conducted during the ice season, between November and March, showed that the amount of energy produced by...

Vestas introduced a de-icing system at the wind energy conference Vind 2013 in Stockholm. The system is based on a hot air flow within the blades The long awaited system has been tested in Canada for the past winter season. Now a prototype is ready for field testing...

A water droplet on a superhydrophobic surface. The build-up of ice and frost is a big problem in many industrial applications. On cold climate sites around the world icing has a negative influence on the energy production. Can we call on the help of nanotechnology to...
