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).
