With the wind industry booming, many owners of wind farms built during California’s wind boom of the 1980s are thinking about upgrading their wind turbines. However, with everyone thinking greener these days, many are finding alternatives to sending their worn-out wind turbines to the junk yard.

An increasing number of new companies are buying up the old turbines on the cheap, overhauling them and reselling them at cheaper prices. Portland-based Nexion DG, for example, offers recycled wind turbines that the company salvaged from California wind farms.

“To go out and build a new turbine of the size we’re working with, it would end up costing twice as much,” said Matt Stein, director of operations for Nexion DG. “And anybody building components for new wind turbines is focusing on the 1 megawatt-plus turbines because that’s where the action is.”

Perks for customers of recycled wind turbines include cheaper prices as well as shorter waiting times, around two months for a rebuilt machine, rather than a year for a new one.
