When wind turbines have reached to a life that oldest machines are reaching their designed life, it is intended to maintain the WTGs in operation until year 40.

This requires conducting a technical study on them to identify priorities, and structural and safety components. To point out which strategy to be followed (replace, reinforce, or inspect and repair if damaged), below key factors need to be determined for each turbine:
 * The physical condition
 * Theoretically admissible lifetime
