Abstract

The electricity mix and access duration in Nigerian educational institutions is poor. This paper presents analysis of the off-grid optimal energy systems (OES) for serving a Nigerian university building load. The feasible system for serving the demand load of 250kWh/day for the building is a hybrid power system consisting of a 75kW rated solar PV, 40kW biogas engine and a 30 number 1kWh battery bank storage operating with a 33.6kW converter. The OES’s COE and NPC are 0.253$/kWh and $175219.7 respectively. Scenario analysis outcomes indicate that the building OES varies with load and resource potential.
