Technical assessment for sub-sea interconnection

REQUEST FOR EXPRESSIONS OF INTEREST (CONSULTING SERVICES – FIRMS SELECTION) Saint Kitts and Nevis Resilient Renewable Energy Infrastructure Investment Facility Project Loan No./Credit No./ Grant No.:_ GFPP Grant No. TF0C9072 Assignment Title: Grid Modernization and Submarine Cable Interconnection Study Reference No . (as per Procurement Plan): KN-MPIEU-528498-CS-CDS The Government of Saint Kitts and Nevis has received financing from the World Bank toward the cost of the Preparation Grant for the Caribbean Resilient Renewable Energy Infrastructure Investment Facility – SOP2, and intends to apply part of the proceeds for consulting services. The consulting services (“the Services”) include a study that shall explicitly address the climate and disaster-risk vulnerabilities typical of Small Island Developing States (SIDS), including hurricane and cyclone resilience of grid and submarine cable infrastructure, seismic and volcanic hazard exposure characteristic of the Lesser Antilles, and regional energy-security cooperation. The assignment will be for a duration of 10 months and shall deliver a technically robust, investment-ready roadmap for modernizing the electrical grids of Saint Kitts and Nevis and interconnecting them via submarine cable, enabling full integration of renewable energy — including the proposed 30–50 MW geothermal plant, utility-scale solar PV, wind, and battery energy storage systems (BESS) — into a resilient, climate-responsive grid. Specific objectives include: Grid Modernization: assess and redesign transmission and distribution infrastructure on both islands, including reconfiguration to a 69 kV ring topology, to reduce losses, improve reliability, and prepare the network for high renewable penetration. Geothermal Integration: evaluate and specify transmission and substation requirements for delivering up to 50 MW of geothermal generation to both islands. Submarine and Terrestrial Cable Interconnection: develop a technical, economically, and envi
