Introduction |
Per capita consumption of electricity in Nigeria is currently estimated to be |
149 kWh/year, which is considered very low compared to 13,246 kWh/year per |
capita electricity consumption in the USA (World Bank Data 2015). This demon- |
strates low access to electricity, which is a consequence of poor electricity gener- |
ation and supply. While a large hydropower potential exists in Nigeria, even above |
the total electricity demand of the country, by 2013 this technology only accounted |
for about 32% of the total installed generation capacity connected to the grid. This |
has led to an extensive use of diesel- or gasoline-operated generating sets for |
electricity generation for industrial and commercial activities. These emissions |
are associated to the wide use of small-scale fossil fuel-powered generators by |
about 55% of its 180 million people, yet to be connected to the grid (Nnaji 2011) |
(BPE 2011) (Energy Commission 2013) (SEC, 2014). Tuwan Agribusiness Resort |
(TAR) in Kaduna State, Nigeria, developed by Premier Agricultural Development |
(PAD) Ltd. is an agricultural service provision centre offering agricultural value |
chain development services to rural farmers. TAR has demonstration facilities that |
show various technologies in production and processing of crops and fish. The |
demonstration facility sits on a 15 hectare plot of land with a stream of water |
flowing across it. Requirements for electricity are lighting and powering equipment |
in offices, animal feed production and storage warehouse, recreation spots, lodging |

facility and the fish fingerling production hatchery. This is currently being met by |
two 25 kW diesel generators, which increases the operational cost of running TAR |
beyond what is expected when electricity is accessed from the grid and makes the |
venture unprofitable in the long run in addition to the considerable negative |
environmental effects of associated high greenhouse gas (GHG) emissions. |
Initiatives similar to TAR are fundamental in Nigeria, where there is a need to |
support food production activities to enable reduction of hunger and poverty in the |
country, with about 70% of the population depending on agriculture for income |
(Osugiri et al. 2012) Fig. 1. |
With booming energy demands from a growing population, one major house- |
hold or business decision is the source of their energy supply, by either renewable |
sources, fossil fuels or a combination of both. |
This study analyses, at prefeasibility level, the technical, economic and envi- |
ronmental advantages of a proposed run-off river, mini-hydro power plant on the |
Tuwan River supplying part of the energy demand of TAR in comparison with |
supplying the full demand with two 25 kW diesel generators. This is a relevant |
project to the community since TAR, an agribusiness service provision outfit, is a |
social enterprise with a potential to stimulate the creation of over 1000 jobs when |
fully operational. The expected medium-term outcome is the provision of a viable |
sustainable alternative to electricity supply for TAR, development of local capacity |
and community awareness on clean energy and sustainable development, while |
motivating research by local communities and tertiary institutions. In addition, it |
will serve as guide for other development agencies and small business owners |
investing in local communities on meeting their electricity needs beyond the classic |
choice of purchasing a diesel generating set (The Economist 2010). |
