Abstract

Electricity challenge in Nigeria is such that only a dramatic increase in both generation and distribution capacity could leapfrog it out of the situation. Reports show that about 61% of the population have access to electricity, and those that do have are currently grappling with epileptic supply. The power network has installed capacity of about 12.5GW whereas the distribution network has capacity for about 6 GW, and often only about 4.5 GW is available to the consumers. Shortfalls are often met with private generations using diesel generators, resulting in noise and environmental pollution with the attendant health consequences. Frightfully so, the challenge is further exacerbated by the burgeoning population. Nevertheless, the government have set an ambitious target for increasing electricity access in VISION 2030 national development plan. A major milestone of this policy is the audacious ambition to increase the existing grid capacity to 30 GW, with 30% of the mix coming from low carbon technology sources. This study explores the use of available renewable energy resources at eleven locations in different regions of the country for optimal generation of energy in contribution to the Nigerian energy matrix. The study was conducted using HOMER™ and Power BI models. Four energy sources were investigated comprising of solar, wind, hydro and diesel. Our findings show that most places in the southern and middle belt parts of the country support mini-grid systems but are more receptive to grid extension, while a majority of the locations in the north are more environmentally friendly to the implementation of mini-grids. In addition, most places investigated in the south, solar technology contributes more than 80% to the energy mix, meanwhile, most northern locations despite having higher solar irradiation are better suited for wind technology with above 60% contribution to the fold.
