Operators view on dealing with wind farms in cold climates and potential to save costs

At extreme icing sites, the energy consumption of blade heating is not negligible and blade heating systems could be sometimes used at half power to save energy, or have an optimized, low-power, anti-icing mode, says René Lemoine, Swiss Winds Developments. Learn more here.

Wind Energy IQ conducted an exclusive interview with Rene Lemoine on how to cope with icing events, ice assessment and the potential for cost savings during operation.

Operators view on dealing with wind farms in cold climates and potential to save costs

  1. 1. Swiss Winds Development on how to cope with icing events Expert Interview www.anti-icing-wind-turbines.com
  2. 2. IQPC: You are Project manager - wind farm development at Swisswinds Development. Can you give us some more information of your background and your current project? René Lemoine: I am physicist and worked before at the Royal Meteorological institute in Brussels. After 10 years at this institute I left for a new job as consultant in renewable energies and energy efficiency in buildings. I quickly specialised in wind energy. Four year ago, I started this job as project manager at Swisswinds Development in Switzerland. At Swisswinds, we develop several alpine wind farm projects, mostly in Canton Wallis. The best example is the Gries wind farm, where a first wind turbine was built in 2011 at 2.400m altitude. Three additional wind turbines were just granted building permits and will be erected next year. IQPC: Which improvements do we need – in your opinion – to assess icing risks in the resource assessment phase towards a more bankable project? RenéLemoine:Energylossesdue to icing are very hard to estimate. The link between measured/ observed icing and energy losses depends on so many parameters. The resource assessment should at least be able to tell you if you need de-icing, if you need a de- icing system that runs during operation, or even a system that does anti-icing (preventive). This way you can chose your strategy: estimate energy losses if they are moderate, or fight losses with the right technology if losses are too large. The resource assessment should at least tell you which way you should go. www.anti-icing-wind-turbines.com RenéLemoineisProjectManagerWindFarmDevelopmentatSwissWindsDevelopmentinSwitzerland, and will present on the lessons learnt operating in cold climates at the Gries alpine wind farm at this year’s international conference Anti-icing for Wind Turbines. Before the event takes place 06 - 07 May 2015 in Hamburg, Germany, we had the chance to talk to René Lemoine about needed improvements to assess icing risks in the resource assessment phase towards a more bankable project, and about the potential to save costs during operation.
