The contractual warranty, also called Defect Notification Period (DNP), must be used to verify that the performance of our turbines is the one indicated by the manufacturer in its specifications.
To compose this newsletter, we first perused the annual and quarterly financial reports of all U.S.-based power generation equipment manufacturers that have reported warranty costs from 2003 to 2023. We
The AWEA Operations and Maintenance Recommended Practices provide guidelines for managing wind turbine warranties, particularly focusing on End of Warranty inspections.
Turbine servicing - Act before the warranty is over US: Of all the inspection cycles for a wind project, the end-of-warranty quality assurance inspection is possibly the most important to a
This PEAK Wind Products checklist provides a generic overview on most relevant End of Warranty activities for handling the expiry of the defects notification period under the turbine supply agreement.
When the warranty period of the Original Equipment Manufacturer (OEM) is almost over, an end-of-warranty analysis becomes essential for wind turbine owners. During the

Of course, where there is a product failure, there is a warranty. So this wave of turbine malfunctions and collapses over the past couple of years is really a warranty story. This is particularly interesting because each warranty claim is from one business to another, e.g. a power company to a manufacturer.
End of Warranty projects consist of several workstreams and involve different functions across the owner’s organization. Therefore, well-defined EoW planning considering main EoW activities is key in bridging both commercial and technical aspects and delivering a successful EoW project.
And relatively new and experimental technology means a higher likelihood of product failures, recalls, and other issues that can drive up warranty costs. So the proportion of U.S. power generation equipment product warranty costs that belong to GE will continue to fall, even as GE itself transitions to renewable energy.
GE held $1.89 billion in warranty reserves at the end of 2021, and that balance increased to $2.15 billion at the end of 2022. Next, we are going to take a look at China's largest wind turbine manufacturer, Goldwind. China has accounted for a growing share of the wind power industry over the past decade.
In fact, on paper, it looks like around half of that $500 million went right into the reserve balance, at least for now. GE held $1.89 billion in warranty reserves at the end of 2021, and that balance increased to $2.15 billion at the end of 2022. Next, we are going to take a look at China's largest wind turbine manufacturer, Goldwind.
