Danish wind turbine manufacturer Vestas has announced that its multi-rotor concept wind turbine has generated its first kWh.

Earlier this year Vestas announced that it was installing a multi-rotor concept wind turbine at the Risø test site near Roskilde, Denmark. On Monday, on its Facebook page, Vestas announced that the multi-rotor concept turbine had produced its first kWh.

“Following satisfactory results of necessary tests, the multi-rotor concept turbine recently produced its first kWh according to the plan,” the company said on Facebook.

“Right now we are testing various software functions,” explained Erik Carl Lehnskov Miranda, Senior Specialist, Electrical, Load & Control at Vestas. “One of them is the cut-out functionality, i.e. if the concept demonstrator stops when it reaches the cut-out wind speed. Another one is the yaw system supervision that shuts down the turbine in case the yaw misalignment exceeds certain values.”

The multi-rotor concept turbine will undergo a series of tests and monitoring over the next few years to determine the design’s feasibility, specifically the technical feasibility of operating and controlling a multi-rotor turbine.

“Installing a concept turbine shows that innovation sometimes entails entirely new thinking and new approaches,” said Jorge Magalhaes, Senior Vice President, Vestas Innovation & Concepts, in April. “This process of continuous innovation and exploration is extremely important. It provides us with essential knowledge that can help us bring down our products’ cost of energy and integrate key technologies to solve our customers’ challenges. Ultimately, the goal is to assess if we can build an even more cost-efficient turbine by challenging the scaling rules.”
