Ready for a future of improved wind farm sustainability
As of this writing, the eight V80 turbines are in the final stages of refurbishment and will be shipped to Scotland and installed on the new site in the autumn of 2021, realising Eurowind Energy’s ambitions to combine cost savings with environmental considerations.
“It would have been a shame to just let these turbines go to waste”, says John Hemdrup Jakobsen. “The Vestas V80 turbines are fairly sturdy machines, and with a light refurbishment, they will be able to run for another 15 years as well. We will have doubled the lifetime of these turbines. Instead of just letting them go to waste and instead of using resources to remanufacture the materials in them, we reuse the parts and add a few bits and bobs”. Sustainability is a consideration in the project. For example, the original turbine gearbox oil was drained and stored when the turbines were taken down. Now unsuitable for gearbox use, the oil will be reused in the tower damping systems, eliminating the requirement to buy new oil for this and reducing the amount of waste oil generated during the project.
The project sets new standards for wind farm sustainability and as such is a perfect fit for Eurowind Energy’s ambitions to develop a position as a leading developer and operator of sustainable energy projects. John Hemdrup Jakobsen does not rule out using DEIF solutions for similar projects in future if the refurbished wind turbines perform as expected.
“We might well consider retrofitting other turbines with a DEIF solution” he says. “If we had a set of turbines somewhere in the world on a wind farm that was not performing as it was supposed to, we might decide to use a DEIF system in those as well”.
