It will supply 66 V155-3.3MW turbines for two undisclosed projects in China with a combined capacity of 201MW and expected online next year.
The turbine, which was introduced to the Chinese market in June 2019, has the largest rotor (155 metres) and lowest power rating (3.3MW) of Vestas’ 4MW platform, the manufacturer said.
This gives it a specific power rating of 175W/m2, and will help it “optimise a project’s capacity factor in low wind speeds”, Vestas claimed.
China has “a growing number of low and ultra-low wind sites”.
Vestas also said the turbine’s lower rotor speed would produce low sound power levels.
The V155-3.3MW is currently only available in China, a Vestas spokesman told Windpower Monthly.
It leverages existing technology from the manufacturer's 4MW platform and a prototype is currently being manufactured.
Thomas Keller, president of Vestas China, said the turbine was an “optimal fit” for China’s low wind market, especially as the country “transitions to distributed wind and grid-parity projects, causing a more competitive and complex business environment”.
Vestas will manufacture the turbine's nacelle at its factory in Tianjin, eastern China. An undisclosed local partner will produce the 76-metre blades at its factory also in Tianjin, the manufacturer added.
It expects to deliver the turbines and commission the projects, which were both successful in China’s ongoing auction scheme, in Q3 2020. The manufacturer will also service the turbines for five years.
