AARHUS, Denmark—The first commercial wind farm to incorporate eight-megawatt turbines began commercial operations just last month. But even as the blades start turning, the approximately 640-foot MHI Vestas V164 turbines—dubbed the world’s most powerful a few weeks ago—are already playing second fiddle to a sleeker younger cousin.
MHI Vestas announced this week that its engineers have tweaked the V164 platform, boosting the offshore turbine’s maximum output by about 20 per cent. The upgrades increase the turbine’s capacity to 9.5 MW from 8.0 MW.
Torben Hvid Larsen, the company’s Chief Technology Officer, said his team was able to achieve the power boost with only “minimal design changes.” He credited a redesigned gearbox and upgrades to the V164’s cooling system for much of the energy increase.
While the turbine retains its 262-foot (80-metre) blades, as well as its rotor diameter of 538 feet (164 metres), its nacelle is slightly larger compared to its eight-MW cousin.
MHI Vestas, a joint venture between Japan’s Mitsubishi Heavy Industries and Denmark-based Vestas Wind Systems, says just one of the new turbines can power the equivalent of 8,300 U.K. homes.
Like other countries in northern Europe, the U.K. has been invested heavily in offshore wind energy as turbines become more affordable. MHI Vestas says the supercharged turbine will continue to drive down costs and help it push toward a global expansion.
