Vestas has introduced an anti-icing solution which they say will remove ice built up on the blades that would otherwise reduce wind turbines’ annual energy production.
Vestas Anti-Icing System™ is based on electro-thermal heating elements embedded in the laminate directly below the blade’s surface. The control system includes different operational modes allowing the heating elements to separately create the optimal heating level, increasing effectiveness and minimizing energy consumption. This results in fast and targeted anti-icing action tailored to the specific icing situation. Vestas Anti-Icing System™ is designed to operate both in rotation and standstill, thereby being applicable from low to high ice severity.
In most common icing conditions, the system ensures a minimum of 90 percent production retention. The system complies with the latest warranty guidelines.
Vestas estimates a potential market size up to 14.6 GW from 2018 to 2026, mainly in Sweden, Finland, Norway and Canada.
The company also introduced the Vestas Ice Assessment™ siting tool which uses metrological models and algorithms to provide an accurate and precise ice assessment down to turbine level..
Building on 16 years of experience within cold climate and 4 GW of installed turbines in ice-prone sites (above IEA ice class II), the two new cold climate solutions are developed and optimized based on extensive performance data insights, gathered from thousands of turbines in cold climate sites.
"Vestas Anti-Icing System™ significantly increases the potential for wind production in many cold climate locations where the risk of icing has constrained the otherwise excellent wind resources,” said Brian Daugbjerg Nielsen, Senior Product Manager in Vestas Product Management.
