6 FAQs about [Service life of wind power tower]

How long do wind turbines last?

The expected service life of wind turbines is approximately 30 years. This does not mean that every individual turbine component is designed to last for 30 years. While foundations and towers are expected to meet that timeline, blades, gearboxes, generators, and other smaller hardware may need to be repaired or replaced earlier.

Do wind turbines need a lifetime extension?

A significant number of wind turbines will reach the end of their planned service life in the near future. A decision on lifetime extension is complex and experiences to date are limited. This review presents the current state-of-the-art for lifetime extension of onshore wind turbines in Germany, Spain, Denmark, and the UK.

What percentage of wind turbines are older than 15 years?

In 2016, 12% of the installed wind turbine capacity in Europe was older than 15 years. This share increases to 28% by 2020 . These wind turbines will soon reach the end of their designed service life, which is typically 20 years.

What is a wind turbine lifetime extension assessment?
