How long do wind turbine warranties last?

These warranties were usually negotiated at the time of wind turbine purchase and the standard warranty “built into” the sales price of the turbine was two years with a three year extension available for an additional per turbine, per year charge. Figure 3 Over the last 20 years, the length of warranties has decreased dramatically.

What is the end of warranty strategy for turbines?

As turbines approach the end of their warranty period, it is therefore critical to put into effect a well thought out end of warranty strategy. The first step should be sourcing an independent inspection of each and every turbine that is coming off warranty. It is critical that this inspection be done before the warranty ends for several reasons.

What is a wind turbine supply agreement?

Almost all wind turbine supply agreements are very specific about both the maintenance schedule and who is to perform the work.

How to plan a successful end of warranty project?

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.

Why are GE Power generation equipment warranty costs falling?

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.

Are power curve and LVRT warranties still valid?

Yes, Power Curve, LVRT, HVRT, and other performance or compliance warranties are still valid and important, regardless of whether a Comprehensive O&M is in place. But failure-based equipment warranties (standard 1-year ones) get nullified under Comprehensive O&M, unless the IPP plans to take over maintenance.
