What is the average lifetime of a wind turbine?

Explanation:
Wind turbines are designed to operate reliably for roughly two decades. The main idea is that after about 20 years, the wear on components like blades, gearboxes, generators, and other systems makes ongoing operation less economical without major refurbishments. Because this 20-year mark lines up with typical project lifespans and economic planning, it’s considered the standard average lifetime. Some turbines can reach 25 years with excellent maintenance and occasional upgrades, but 20 years sits in the middle of the common range, making it the best general estimate.
