AbstractInnovative offshore grid designs such as integrating offshore wind farms (OWFs) with interconnectors are gaining popularity. Adequate investment in these designs requires aligning the interest of stakeholders through an appropriate cost allocation method. The aim of this paper is twofold. First, it shows how welfare distribution can influence a stakeholders offshore grid design choice. Second, it evaluates the effect of various cost allocation schemes in aligning diverse stakeholder interests toward efficient grid design. The results confirm that an investment in an efficient offshore grid design may not be guaranteed as long as the chosen cost allocation method ignores the welfare distribution effect. Most methods fail in this regard. Even when they provide cost incentives, they do not always ensure cooperation. Cognizant of this limitation, this study proposes a method that allocates costs in proportion to the incremental net benefit (PINB) of each stakeholder. This method reflects both the distribution of welfare and cost savings.
