Abstract This study aimed to analyze the differences in perception of the offshore wind power project and the personal and social determinants that influence the acceptability of the project among residents in areas where there is conflict over offshore wind power. In particular, rather than viewing local residents as a single group, we subdivided them into fishermen and non-fishermen, people with and without experience in past government-led projects, and residential areas to compare and analyze differences in perception of the acceptability of offshore wind power. As a result of the analysis, the acceptance of offshore wind power was found to be higher among fishermen than among non-fishermen, and the group that experienced conflict with the government in the past showed higher acceptance than the inexperienced group. Also, by region, the acceptance of offshore wind power was high in that order: Incheon, Jeju, and Busan. Fishing activities, age, and visibility of offshore wind power plants were found to be significant factors influencing residents' acceptance of the offshore wind power project. Through this study, it seems necessary to take a delicate approach by segmenting stakeholders according to each individual's environment and experience, rather than viewing offshore wind power residents as a single group.
