Life Cycle Cost Analysis of Small Wind Power Generation–A ...

This paper analyses life cycle reliability and maintenance of wind turbines. The analysis applies the concept of failure mode and effect analysis (FMEA) and Bond graph modelling to simulate the effect of changing maintenance strategies on the life cycle cost of wind turbines. The analysis results can be used to determine the optimum maintenance schedules and preventive part replacements. 2.

Have you ever read that wind energy “is the cheapest energy source available?” These claims are based on cost-estimates that assume the lifespan of wind turbines to be 30 years. However, according to the U.S. Energy Information Administration (EIA), the lifespan of wind turbines is about 20 to 25 years.. In Iowa, wind turbines are reaching the end of their lives even faster as MidAmerican ...

A comparison between the onshore and offshore impact of the very same wind turbine (a Vestas V90. 3.0 MW) was carried out by Vestas. Results of this LCA show similar environmental profiles in both cases. However, offshore wind turbines produce more electricity (11,300 - 14,800 MWh/turbine) than onshore wind turbines (6,900 - 9,100 MWh/turbine).
