Abstract
There is the need for the provision of an
alternative sustainable electric power supply system to
provide electricity for Community Service Facilities (CSF)
such as Information Communication Technology (ICT) for
e-service to rural communities, rural banking, hospitals,
and supply of potable water if the social and economic lives
of rural citizens in Nigeria are to be improved. This paper
presents the feasibility study of a stand-alone Photovoltaic
(PV)/Hydro power system for CSF in Ogologo-Eji Ndiagu
Akpugo in Nkanu-West L.G.A located in South-Eastern
Nigeria on Latitude 6°35'N and Longitude 7°51'E with
annual average solar daily radiation of 4.73kWh/m²/d. The
river used for the study is Atavo stream also located in
Ogologo-Eji Ndiagu Akpugo. In carrying out the flow
measurement of the stream, the length, width, and depth of
the stream were measured, while a floating object was used
as the technique for the determination of the surface speed.
The readings were taken over a period of 2 years
(2010-2012) with an average stream discharge of 26.42
M3/s. Load estimates of a typical rural ICT infrastructures,
banking and hospital were estimated. The simulation results
show that the renewable energy system (RES) is capable of supplying sufficient power, is reliable, economically
viable and, most importantly, is environmentally friendly.
The Optimization study indicates that energy requirements
to provide electricity for community service facilities load
demand of the 58 kWh/day with a 3.7 kW peak and a
deferrable load of 6.6kWh/d with 1.1kW peak can be
accomplished by a combination of the 3 kW solar PV array,
2.62 kW hydro turbine, 24 Surrette 6CS25P Battery, and
a 4 kW AC/DC converter.
