Economic evaluation of the life cycle of a wind farm and improving the levelized cost of energy in region Champagne-Ardenne, France

This study focused on an industrial area, i.e., Champagne-Ardenne, France, containing 25 wind turbines with a lifespan of 25 years. We assessed the economic situation from the beginning of the operation of this plant to the end of its lifetime using the levelized cost of energy (LCOE) indicator, which assesses the average cost of energy production during a project. We also considered the environmental cost associated with the wind sector. The objective of this study was to explore the effects of all parameters, including the calculation of the LCOE indicator, to provide decision-makers and local authorities with optimization solutions. We also developed an optimization algorithm to provide the best combination of all LCOE parameters for producing sustainable energy at the lowest cost.
