Ireland Offshore Wind Energy Infrastructure Development Feasibility Study with Renewable Energy Market Outlook

Executive Viability Abstract

This feasibility study evaluates the development of a 500MW offshore wind energy project off the East coast of Ireland. With Ireland's commitment to 5GW of offshore wind by 2030 and 37GW by 2050, the regulatory environment is increasingly favorable. The project focuses on fixed-bottom technology in the Irish Sea, leveraging the OREDP II framework to ensure alignment with national grid upgrades and decarbonization targets for the heavy industrial and data center sectors.

## Market Analysis Ireland possesses one of the most significant offshore wind resources in Europe, with a sea area seven times its landmass. The Market is driven by the Renewable Electricity Support Scheme (ORESS), providing long-term price certainty. Demand is bolstered by Ireland's status as a global data center hub, requiring high-uptime green energy. Competition includes major players like SSE Renewables and Ørsted, but the 'Phase 2' maritime area consents provide ample room for new infrastructure. ## Technical Feasibility The project utilizes 15MW+ Siemens Gamesa or Vestas turbines. The East Coast (Irish Sea) offers shallower waters (20-40m) suitable for monopile foundations, reducing Capex compared to floating offshore wind (FLOW). Key technical hurdles include grid integration at EirGrid nodes and the requirement for specialized heavy-lift vessels which are currently in short supply globally. ## Financial Projections Total Capital Expenditure is estimated at €1.65 Billion. Revenue is projected through a combination of ORESS-2 auction strike prices (estimated at €80-100/MWh) and Corporate Power Purchase Agreements (CPPAs). Annual Opex is modeled at 3% of Capex, covering turbine maintenance and port logistics. ## Risk Assessment Primary risks include prolonged planning permission timelines under the Maritime Area Regulatory Authority (MARA) and global supply chain inflation. Mitigation strategies involve early engagement with the supply chain and securing grid connection agreements early in the development cycle.
