Evaluation metrics system of offshore wind power projects based on fuzzy analytic hierarchy process

Traditional project evaluation models were focusing on individual project impact factors and there is a lack of systematic research on comprehensive project evaluation during the pre-investment period, which include construction assessment and economic evaluation. In light of the complex construction environment and high investment cost of offshore wind power projects, a key metric evaluation system for offshore wind power projects during the pre-investment period was put forward based on the multi-level fuzzy comprehensive evaluation method. Two specific cases in China were evaluated with the assessment model. The results showed that Case 1 in the East China Sea was built in a less favourable environment than Case 2 in the South China Sea, but its electricity price is higher. The system can assist the decision-making procedure by systematic evaluation and comparison of investment opportunities. The system provides technical support for development planning, policy making, and investment management in the offshore renewable energy field.
