Background Nigeria’s population is currently over 160 million people but only about 40% of these population have access to electricity. The larger population without access to electricity lives in rural communities. Those off the grid now rely on biomass, kerosene lantern and local paraffin lamps as their energy source. The World Bank estimates that: 780 million women and children breathing kerosene fumes inhale the equivalent of smoke from two packets of cigarettes a day. According to the report released this year (2012) by the National Electricity Regulatory Commission (NERC), a total of 23.73 million households, out of the 28.9 million in the country, do not have access to the national electricity grid. This means that 82.1 per cent of Nigerian households do not have access to electricity from the national grid. Ofetebe Community in Ovia North-East L.G.A of Edo State, southern Nigeria is among the numerous communities that do not have access to electricity. With a population of about 2,000 individuals including women and children, the community is located in a very difficult terrain near the forest reserve of Odighi community and borders of River Ose. The main occupation of the indigenes of the community is fishing and farming. Despite the high level of farm activities in this community, there is no good access road. The poor access road contributes to the high price of kerosene used as fuel for lighting which cost 250 Naira per litre in the community. Their little and hard earned income from agricultural produce is spent on non-renewable energy sources which has not only increased poverty in the community but also the stress of sourcing kerosene during scarcity. Due to the emission of CO2 gas from these unsustainable energy sources, the people are exposed to respiratory ailments resulting from the continuous inhaling of obnoxious and dangerous gases. Also the community clinic does not have electricity supply thereby forcing health workers to close before it is dark. There is no access to clean and portable water in the community. The indigenes depend on rain water and the water from River Ose as their water source. As a result of this, the people constantly suffer from water borne diseases. The Solar Micro Off-Grid Facility (SMOF) will be used to generate 4,000 watts (4kw) of electricity in a central location within the Community which will be called the ‘Green House’. From the Green House, electricity will be distributed in a 'STAR' network within a 500 metre radius in order to minimise power loss during transmission to power an existing community borehole (which is currently out of use due to lack of power supply), the Community Clinic and 40 Households (HHs) (which also include houses that have barbing shops, Retail shops and Local Relaxation Spots attached to them). Indoor Lighting System (ILS) consisting of 90LED lamps & a 12V/5AH battery pack shall be provided to the beneficiaries. There is no permit or clearance to be obtained from the state or federal government as it will generate electricity that is less than 1MegaWatt. Based on average solar insolation installation of 4KWh/m2 in Ofetebe community in particular, a minimum of 16.0KWh of electricity shall be generated daily by the SMOF. The energy generated shall be stored in a large battery bank for use during sunset. Electricity shall be supplied daily by the SMOF from 6pm - 10pm (4 hours of electricity supply) which will allow them watch their Televisions, operate their DVD, and listen to their Radio set for entertainment and get both local and international information. However, the beneficiaries will have electricity supplied from individual battery pack (Backup power) for extended period of 2-8 hours depending on usage. A prepayment keypad meter shall be installed in each households and Village shops to ensure payment of electricity used/consumed.


Executive Summary The project “Providing Sustainable Energy in Ofetebe Community Using Solar Micro Off-Grid Facility” was implemented by the Community Research and Development Centre (CREDC) as part of the PREEEN Project (Promoting Renewable Energy and Energy Efficiency in Nigeria) as been funded by the Global Environment Facility Small Grant Programme (GEF-SGP/UNDP) Abuja, Nigeria. The Project is located at Ofetebe Community in Ovia North-East Local Government Area of Edo State, Southern Nigeria. Ofetebe community is yet to be connected to the national grid and the people of the community rely on candles, kerosene lamp, bush lamp, and generators for those who can afford it as their sources of energy for lighting and other services. These energy sources do not only expose them to the dangers of respiratory diseases but also the CO2 gas emitted from these energy sources contributes to climate change. The objectives of the project were to; reduce CO2 emission from unsustainable energy sources in Ofetebe Community by using solar micro off-grid facility as a clean energy source, to increase access to clean and portable water in Ofetebe community, to build Capacity of 15 youths of the Community to be able to install and maintain Solar Micro off-Grid Facility and to create awareness in Ofetebe community and beyond on the role of renewable energy technology in preserving the environment. Project activities reported in this report includes; courtesy visit to Ofetebe Community, the training workshop for 15 community youths and the first phase of the installation activity By the completion of these activities, it is expected that, 15 youths that were trained can now install and maintain solar facility and also that 3 members of the community are now employed as Local Energy Regulatory Committee members to undertake management of the project.


Courtesy Visit to Ofetebe Community On the 12th of July, 2013, the staff of the Community Research and Development Centre (CREDC) paid a courtesy visit to the elders and youths of Ofetebe Community. Staff member that embarked on the trip includes Mr. Ogbemudia Godfrey (Programme Manager), Miss Agharese Edevbaro (Operation Manager) and Mr. Osazee Uyigue (Head of Technical Unit). They were received by elders and the leadership of the community youths at the residence of Pa. Edobor who is currently acting as the Community Head. Addressing those present at the meeting, the Programme Manager, Mr. Ogbemudia said that the CREDC Team was in the Community to inform them that the proposed solar off-grid project will commence in August 2013 with the training of the 15 selected youths and the implementation of first phase of installation activity. He used the medium to solicit for their support to make the project implementation process a success.

At the Village Head Residence

Responding on behalf of the Community, the Community Secretary Mr. Friday Omoregbe appreciated CREDC and the sponsors of the project - GEF SGP/UNDP Nigeria for coming to their aid in providing electricity for them using Solar Micro Off-Grid Facility. According to him, they have been getting promises from both the Government, NGOs and other organizations before now but none was fulfilled but today, he is a very happy man because God has decided to bless their community through GEF-SGP and CREDC. He however on behalf of the community pledged their full support to the project.


Training Workshop for Selected Community Youths The training of 15 youths in Ofetebe Community as solar technicians was held between the 21st and 23rd of August, 2013. The training which was coordinated by Mr. Valentine Eku focused on solar system components, sizing of solar projects and installation of solar systems. Other components of the solar system which were discussed by the consultant include, the charge controller that regulates the charging process of the battery by the solar panel, the inverter which is used to covert direct current (DC) from the solar system to alternating current (AC) which can be used to operate our household appliances. He also discuss the use of the battery which is for storing energy that have been generated by the solar cells to be used later when the sun goes down.

Mr Valentine Eku

According to him, Sizing a solar system begins with knowing the energy to be consumed. This is done by summing up the power rating of all the appliances that will be powered by the system and then multiply the value by the number of hours they will be used per day and also multiplying the figure you got by the sunshine factor which in the case of southern Nigeria should be between 4hours to 4 and1/2 hours and this will give you the rating of solar panels that will be used or purchased.

. He said that to know the type of charge controller that will be suitable for a solar system, the short circuit current value behind the solar panel written on the solar panel name plate should be multiplied by 1.25 and the value gotten gives you an idea of the controller to be used. Charge controllers are rated in ampere. He added that batteries are rated in amp/hour to size the battery; you multiply the total energy need by the depth of discharge {DOD} which should be at least up to 50%. First Phase of Installation Activity The installation phase of this project started on the 1st of September, 2013. Equipment’s were transported to the site by speed boat through the Ose River from Owan Community in Ovia North-East Local Government Area of Edo state, Southern Nigeria. The Green House (where the PV System will be installed) was constructed with blocks and zinc roofing sheets. Transmission poles (made of Teak wood) were cut from the forest and used as electric poles. The transmission network which is made up of three distribution cables were connected from the Green House to different locations in the Community to power different electrical equipment such as the Community borehole.


Youth lifting up solar array

Mounting of solar panels was the next task and this was done by bolting each of the 20 units of 200watts solar panels to the solar supports that were fabricated on the ground before lifting it to the top of the roof of the Green House with the help of the community youths. Five solar arrays containing four solar panels were mounted on top of the roof and tilted at angle of 15o due south of the equator.

Equipment being installed in the greenhouse


Two equipment racks were also fabricated and each had a charge controller, an inverter and four 200Ah batteries mounted on them. The cable from the five solar arrays on top of the Green House was connected to a circuit breaker before connecting it to the equipment assembly. A distribution switch used for electricity distribution from the Green House was connected to the PV system. The facility was later earthed to secure it from damage from lightning. The next task was the installation of indoor lighting units for the 30 benefiting households by the trained youths and CREDC Team. Each household was given 3 LED lamps and a socket with three backup batteries. The faulty borehole pump in the Community was replaced with an efficient solar water pump by a civil enginnering company which was contracted to do the job.
