Vestas Addresses Extreme Conditions

Vestas has introduced a new variant of the 4 MW platform. The V136-4.2 MW Extreme Climate wind turbine is specially designed for maximum power generation at low to medium wind speeds, while coping with extreme weather conditions.

The turbine was presented at the current Japan Wind Expo 2019 in order to underline its specific suitability for many project locations in Japan and Asia that have been problematic in climatic terms up to now. But the plant is also interesting for other markets with similar conditions all over the world, such as South China, the Caribbean and the UK.

The Extreme Climate variant builds directly on the popular V136-4.2 MW turbine and offers design enhancements such as reinforced rotor blades and a reinforced hub. The new variant is capable of withstanding extreme wind speeds of 53 m/s (exceeding IEC Class I extreme wind speed) and extreme gusts of up to 74-78 m/s. The new turbine is designed to withstand the most severe wind conditions. The variant is also designed to withstand lightning strikes, which occur regularly in Japan during typhoons.

“With the introduction of V136-4.2 MW Extreme Climate, Vestas is connecting our proven technology with customised solutions to help customers unlock low to medium wind sites with high turbulence”, said Thomas Korzeniewski, Vestas’ Vice President of Product Strategy. “The larger rotor delivers improved energy production, with the strength and versatility necessary to handle extreme wind gusts and high turbulence”.
