“Rural Electrification Project in the North-East of DR Congo : village of Boga, locality of Nyakabale
Currently for young people growing up in the bush, the only outcome after primary school is the leak in the city, where they are often swell the number of idle, living crime such as theft. The council of elders of the village of Boga and all residents are mobilizing for many years to develop innovative projects and give birth to original economic initiatives: Workshops drying, husking and pounding (rice and coffee), craft workshops , woodworking, fish etc..
Electrification and structuring some workshops for villagers to create a new dynamic open to residents of the entire area concerned future prospects unthinkable in the current situation. This is why electrification is more than light! With the creation of sustainable jobs, we hope that this project will start of an integrated development in the bush, essential alternative to the exodus of young people.
The choice of appropriate technology
The Nyakable stream has its source Igandi. It supplies the locality of Nyakabale and offers a vertical drop of about 200 m with a minimum flow of 30 l / sec and more than 100 m3/sec in the rainy season. A masonry intake on the creek will feed a floodway near 400 m hillside. The water will be decanted into the basin charging that feed the penstock 1000 m with an elevation of 120 m and a stabilized rate of 20/25 l / sec.
The installation of a micro-hydro plant is a choice suited with the relief and climatic conditions that characterize the area of intervention: it is indeed a region of humid tropical climate (more than 3 meters of water annual average). The first relief before the first cliff offer interesting gradients to capture the energy of small rivers and turn it into valuable electrical energy while respecting the environment.
At Nyakabla, the available power will supply 20kwa workshops on the day. At night, power generation, with two bulbs of 40 W per dwelling will be well enough to the village of 250 habitations.
The installation of micro-hydro and electrical system
The purpose of the PIRD being sustainable development respecting the environment, so it is a good decision to use a natural and ecological resource presents at Nyakabale: the water like a group uses thermal electric by some people and bad for the environment pleasant Boga.
The choice of PIRD is focused on micro-hydro of IREM brand, equipped with a turbine PELTON. Upon reading the data sheet of the manufacturer and according to the EDF hydraulic UP East experts, the assembly is called very simple and requires basic maintenance uncomplicated to access parts. The micro power will have a sufficient water resources and free to hope for a sustainable supply of the electrical machine.
As for the choice of a power grid buried or overhead, it appears that the underground solution is very well developed and less well-known locally. The network will also air he favored in terms of interviews to come ..
Finally, it is strongly recommended to support these developments by a security awareness, including in response to mechanical and electrical hazards.This awareness could be achieved by technicians from Kilo-Moto (Electricity Company serving the city of Bunia in the north of the village of Boga), with whom PIRD is already in contact.
The installation of electrified workshops
Exploration and feasibility study
Various techniques were visited by PIRD not far from our study area. This survey helped to make a diagnosis on initiatives that seem to work and those that seem more difficult to implement or rent are less able.
Type visited workshops: A beekeeping workshop; a a woodworking shop, a welding shop and workshop husking rice developed in the town of Bunia and Beni.
The workshop rice husking was particularly interesting because it creates a strong productivity gains, while the machines are inexpensive energy (11 kW for a yield of 900 to 1200 kg / h) and simple enough to use. At this stage of the project and from our understandong are ground, this workshop has been privileged because rice is one of the the staple and has grown throughout the village of Boga.
Summary workshop hulling rice:
Productivity (kg / h) 900 1 200
Sale price husked (Ar) 1100 1100
Total Recipe 990 000 1320000
Raw material cost (Ar / kg) 375 375
Raw material cost (Ar / h) = (cost per mat.prem 337,500 450,000
kg x productivity)
Power demand (kW) 11 11
Electricity cost (Ar / kWh in Aditsara) 150 150
Electricity cost (Ar / h pricing Aditsara) 1650 1650
Labor (Ar / h) 1100 1100
Total Debt 340,250 452,750
Estimated gain (Ar / h) 649,750 867,250
A second workshop is planned to meet an identified need in the socio-economic study: Workshop oil pressing, allowing households to Boga to valuable savings on this essential expense, and ensure a vibrant local market with all neighboring villages.
Once the creation of formalized OPEDI and installation of effective electrical network, the cooperative may consider installing electrified workshops. PIRD will then clearly define the nature of its participation in the operation. In one case, the workshops could be a gift from PIRD. They would then be managed by the management committee. Another solution would be to provide OPEDI workshops as a micro-credit.
Microcredit will undoubtedly preferred because it fits better in the current direction of development policy and will be able to meet our goals of autonomy and sustainability: it makes it possible to actually engage beneficiaries by empowering and strengthening their self-determination.
The objective of these new activities will be firstly to accelerate the process of transformation of certain agricultural products to increase the production and sale of these products, and also to make new goods, which will farmers more independence
– motorization of pounding and husking coffee, maize and rice
– drive the oil pressing (following the peanut crop activity) and palm fruit oil, which provide valuable dietary supplement.It is also one of the most important spending.
The villagers are willing to invest in this project and think they can manage by themselves if they receive adequate training.However, as stated by the village chief, an intermediate is necessary to coordinate activities and provide research opportunities and travel.
Budget needed $111 182
