DNV GL has joined forces with Swedish atmospheric science experts WeatherTech to develop an icing model to predict the performance of wind turbines in cold climates.

The partnership will combine WeatherTech’s WICE model, which predicts losses in production due to ice build up on blades, with DNV GL’s database of operating wind farms in cold climates. WeatherTech and DNV GL aim to produce icing loss estimates for turbines.

DNV GL energy business in Northern Europe, Middle East and Africa executive vice president Prajeev Rasiah said: “With greater numbers of wind turbines utilised around the world to meet growing electricity demands, we need to be sure that turbines can function as intended in challenging environments, including cold climates, such as Scandinavia, Northern Russia and Canada.

“By joining our renewables energy analytics department, the WeatherTech team will bring immense knowledge of meteorology and mesoscale to our global pool of experts.

“It is also great to see our renewables expertise grow even further in the Stockholm office, to accompany the exponential growth of the market in Sweden.”

WeatherTech owner Stefan Soderberg said: “The combined strengths of DNV GL and WeatherTech marks the start of a new and exciting chapter in cold climate assessment. The collaborative powers of DNV GL and WeatherTech will provide greater insight into cold climate challenges and mitigation techniques.

“This insight will greatly benefit an entire industry which still has unanswered questions relating to this atmospheric phenomenon.”
