Refurbished

wind turbine

 

Our initial market focus is on redeploying wind turbines in community wind projects throughout the Europe. Given the nascent nature of the refurbished wind markets we often develop our own projects, but prefer to work with other developers seeking a reliable solution to their community wind and/or net-meter project needs.

With a lead-time of less than three-months, we hope developers will find refurbished wind turbines an economical, timely, and wise solution to the current supply issues plaguing the community wind market.

REFURBISHED WIND TURBINES

We conducted an overhaul of the nacelle, blades and towers, is a comprehensive review of all parts of the nacelle, replacing filters, oil seals, replacement of damaged machinery, painting in nacelle, tower, blades, fiberglass work glass blades.
