6 FAQs about [Wind power generation loss rate]

How much do wind turbines lose a year?

Wind turbines are found to lose 1.6 ± 0.2% of their output per year, with average load factors declining from 28.5% when new to 21% at age 19. This trend is consistent for different generations of turbine design and individual wind farms.

How has wind power changed over the last year?

U.S. wind capacity increased steadily over the last several years, more than tripling from 47.0 GW in 2010 to 147.5 GW at the end of 2023. Electricity generation from wind turbines also grew steadily, at a similar rate to capacity, until 2023.

Do wind turbine load factors decline with age?

By accounting for individual site conditions we confirm that load factors do decline with age, at a similar rate to other rotating machinery. Wind turbines are found to lose 1.6 ± 0.2% of their output per year, with average load factors declining from 28.5% when new to 21% at age 19.

What is the average decline rate of wind turbines?

This decline rate appears stable until 2002, after which it reduces for more recently commissioned turbines. Farms built before 2003 have an average decline rate of −0.49 ± 0.05 points per year, whereas those built afterwards average −0.16 ± 0.08.

Why do wind farms lose output a decade?

Onshore wind farm output falls 16% a decade, possibly due to availability and wear. Performance decline with age is seen in all farms and all generations of turbines. Decreasing output over a farm's life increases the levelised cost of electricity. Ageing is a fact of life.

How much do wind farms degrade a year?

When variations in the weather and improvement in turbine design are accounted for, we find that the load factors of UK wind farms fall by 1.57% (0.41 percentage points) per year. This degradation rate appears consistent for different vintages of turbines and for individual wind farms, ranging from those built in the early 1990s to early 2010s.
