How long do turbines last?

These in New York were built between 2013 and 2015.
The sales pitch is that The lifespan of a windmill typically spans 20 to 25 years, but these turbines began to break down in less than three.

New York state spent millions on a lauded wind project several years ago, but most of the turbines now stand idle as officials wait to repair malfunctioning parts.

The New York State Thruway Authority — the governing body of a major toll highway that runs across the state — has taken part in New York’s attempts to transition to renewable energy. From 2013 to 2015, the authority built five wind turbines along the thruway in the western corner of the state.

The project was expensive, with the five windmills costing $4.8 million and another $500,000 for design expenditures. The authority believed that the turbines would pay for themselves, saving as much as $420,000 annually on energy bills.

However, the project did not go as planned. Of the five turbines that are dotted across the thruway from Eden, New York to the Pennsylvania state line, four aren’t even spinning.

“They are currently offline waiting for replacement parts and/or maintenance,” thruway authority spokeswoman Jennifer Givner said, according to Buffalo News. “We’re working with the manufacturer to get replacement parts.”

Between October 2017 and January 2018, all the turbines except for one were taken offline.
