Wind power plays an important role in European low carbon’s energy transition. Offshore wind investments have reached a reasonable maturity over the past decade with more than 90 wind farms in operation in the European countries. The advantages of wind power are many resulting in a considerable growth demand for this technology. This thesis is the result of an intensive collaboration with RINA S.p.A, company sited in Genoa (Italy). An innovative and accurate Discounted Cash Flow Financial Model for Offshore wind power is verified and developed, with the objective to facilitate the evaluation and the decision-making process in Offshore wind projects for possible investors.
