Vestas has unveiled a cable-anchored tower design that it hopes will slash manufacturing costs for giant onshore turbines.
The so-called “cable-stayed tower” features three tensioned multi-strand steel wires that root the turbine to the ground in a bid to reduce leverage factors and loads.
Vestas believes the concept will mean it can use narrower towers on larger turbines that will require less material in order to reduce costs and ease component transport headaches.
The V126-3.45MW prototype, which is being installed at Osterild in Denmark, was first revealed in subscriber-only reNEWS last month.
It features a 137-metre tower and is due to be operational shortly.
The turbine will be tested for the remainder of the year before Vestas decides whether to deploy it commercially.
