Infrastructure Development and Economic Assessment of a Smart Mini-grid Photo-Voltaic Power System for a Strategic Information and Communication Technology Park in Lagos State, Nigeria

This study assessed the technical and design specifications of a proposed smart mini-grid photovoltaic (PV) system for the strategic Katangua Information & Communication Technology (ICT) Park in Lagos State. It also analyzed the system’s techno-economic and environmental viability compared to a diesel generator alternative using an energy technology foresight framework. The smart PV system was designed to support a 4.911 MW power load, featuring a peak PV module size of 15.35 MW, 34,111 PV panel modules, a 10,000 W/48V inverter, and a 10 kWh/48V lithium battery. In contrast, a 250 kVA diesel generator consumed 540 liters daily and emitted 1.5 tonnes of CO2. Life cycle cost analysis revealed that the PV system had a significantly lower cost (N 91.17/kWh) than the diesel generator (N 365.51/kWh), and would eliminate the production of 217,080 tonnes of CO2 over 20 years. The study concluded that the smart PV system is a viable solution with clear technological, economic, and environmental advantages, recommending its implementation for the proposed ICT Hub.
