Energy for Development Case Study – Replication of Rural Decentralised Off-grid Electricity Generation through Technology and Business Innovation

Prof. AbuBakr Bahaj and Rucha Amin from Southampton University write on the University’s Energy for Development (E4D) project, providing renewable and reliable power to rural Kenyan communities.

Reliable and affordable sources of energy are fundamental not only for wellbeing, but also for economic growth and poverty reduction. Rural communities that do not have access to the national electricity network are also deprived of the associated benefits in health and quality of life provided by electrical services such as lighting and refrigeration. Fulfilling the energy needs of developing countries without compromising the environment is a challenge requiring imaginative policies and methods.

The approach adopted by E4D in Kitonyoni, Kenya focussed on a replicable, community based solar mini-grid electrification system aimed at invigorating village trading centres and promoting business innovation. The core of the project is based on a 13.5 kWp solar photovoltaic (PV) array with integrated rainwater harvesting system coupled to a mini-grid. The latter provides power to all trading centre buildings (shops, cafes, schools, health centres, churches etc.) and local businesses that in turn are able to provide charging facilities for electrical appliances, such as LED lanterns and mobile phones, to customers.

A major focus of this project has been to establish an economically sustainable system whereby the community contributes to the project and is responsible for the operation and maintenance of the plant. Income is generated for the cooperative which is also set up as an energy supply company (ESCO) through membership fees, local sales of electricity and share ownership. This income covers the running costs of the project, provides finances to the community as well as contributing to the recovery of the capital cost of the project.

Since the installation in September 2012, there are clear indications that the trading centre in Kitonyoni is being transformed with land prices increasing, a number of new buildings constructed, new businesses opening and existing business owners reporting profit increases.  There has also been a marked improvement in healthcare provisions with a newly donated, fully electrified maternity clinic in operation. Furthermore, one replication project has already been carried out in Bambouti, Cameroon with a third installation in Oloika, Kenya planned for later this year.
