New research has evaluated the performance of American wind farms over the years.

The first in-depth study of wind power plants in the United States shows relatively low levels of performance decline over the years.

US wind power plants maintain 87% of peak performance after 17 years, and newer plants show virtually no yield loss in the first 10 years, according to a recent study from the Berkeley Lab.

Compared to studies on the aging of European wind turbines, the US wind farm shows a slight loss in performance with age, and factories built after 2008 show the lowest levels of performance decline ever found.

A team of researchers from the Energy Analysis and Environmental Impacts Division of the Berkeley Laboratory analyzed the performance of 917 onshore wind projects in the United States.

The US wind market is the second largest in the world and provided 7.3% of the country’s electricity generation in 2019, but this is the first research effort to assess the impact of age. the power station on the performance of the American wind farm.

The results indicate that age-related performance loss can be influenced by technological choices and profitability decisions by project operators. The study proves that recent technological changes have a positive influence on the aging of wind turbines.
