SUREWAVE Economic Assessment – Cost Model and Financial Analysis for Offshore Floating PV (Deliverable D7.4)

This dataset accompanies Deliverable D7.4: Economic Assessment of the SUREWAVE Floating Photovoltaic (FPV) System, developed under the Horizon Europe project SUREWAVE – Structural Reliable Offshore Floating PV Solution Integrating Circular Concrete Floating Breakwater (Grant Agreement No. 101083342). The Excel file (D7.4_surewave_costs_v2.xlsx) contains the detailed techno-economic model used to evaluate the financial feasibility of offshore FPV deployments in three European maritime regions (Mediterranean, Baltic Sea, North Sea) across multiple scales (2 MW, 10 MW modular, 10 MW full-scale). It includes: CAPEX and OPEX breakdowns for pontoons, breakwaters, anchoring, electrical systems, and installation logistics. Energy yield and degradation assumptions over a 50-year horizon, including PV module reinstallation at year 25. Key financial metrics: Levelised Cost of Electricity (LCOE), Net Present Value (NPV), Internal Rate of Return (IRR), and payback periods under base, pessimistic, and optimistic scenarios. Sensitivity analyses for discount rates, cable configurations, and structural design variants. The model supports strategic deployment recommendations and bankability considerations for offshore floating solar in Europe. It is intended for researchers, policymakers, and industry stakeholders interested in techno-economic modelling of marine renewable energy systems.
