Deliverable 7.7: “Final holistic assessment of potential X-Rotor economic impact” aims to provide a regional economic impact analysis of the X-ROTOR technology in comparison with traditional horizontal axis offshore wind turbines (HAWTs). An assessment of the relationship between offshore wind levelized costs reductions undertaken in Devoy McAuliffe et al. (2023): “Modelled LCOE for the X-ROTOR” from WP6, is used to provide input to a system-wide economic modelling framework. The results show a comparative analysis of the aggregate economic metrics including GDP and Jobs. The I-JEDI model used is an Input Output framework used to measure regional economic impacts of renewable energy technologies. Three economic regions are studied Ireland, UK, and Spain. Considering information from D6.2 we assume two market scenarios, one with deployment of 5GW of offshore wind in the three regions to compare X-Rotor and HWATs, and a second scenario with 100% deployment of X-Rotor in all offshore wind generation in the UK so that direct comparisons may be made with the computable general equilibrium (CGE) model in Deliverable 7.8 (Williamson and Allan, 2024).
