“…In many developing countries where access to electricity is low, e.g. rural sub‐Saharan Africa, small‐scale off‐grid solutions are being promoted as an important mechanism in achieving sustainable development goals (Deichmann et al ., ; UN Sustainable Development, ; Abdul‐Salam and Phimister, ). It is often argued that access to small amounts of electricity, e.g.…”

Low power home electrical items such as radios, mobile phones and televisions are an important source of agricultural information for small-scale farmers in developing countries. To empirically test the effects of access to information from these items on efficiency in agriculture, we formulate a stochastic frontier model augmented with a technical efficiency model that controls for an index capturing farmers' 'ability to access information'. The index is constructed with a 2-parameter item response theory (IRT) model based on farmers' access to the electrical items. Using six rounds of panel data on small-scale farmers in Uganda, we find empirical evidence of a significant and positive relationship between farmer ability to access information and farm efficiency. There is also evidence that the size of these effects is larger for more literate hence better educated farmers. Greater access to information also appears to be associated with increased variance of (in)efficiency and output although the form of the increased variances is underpinned by low risk of lower efficiency and output realisations and high likelihood of higher efficiency and output realisations. Our findings imply that access to limited quantities of electricity needed to power these electrical items can have positive farm efficiency effects, 1 Yakubu Abdul-Salam is in the and hence the importance of off-grid electricity (e.g. standalone solar panels) for small-scale farmers in typically isolated communities in developing countries.

“…Based on typical average wind speed in Ghana of 6.1 m/s reported by the Ghana Energy Commission, the estimated power production from the EYO7-8, EYO8-8, and EYO9-8 rotors according to Equation (11) is 1488 W, 1468 W, and 1435 W, respectively. This potential power generation from the small wind turbines meets the power demand of most residential facilities in developing countries as reported in the works of [48][49][50][51].…”

Small wind turbine power generation systems have the potential to meet the electricity demand of the residential sector in developing countries. However, due to their exposure to low Reynolds number (Re) flow conditions and associated problems, specific airfoils are required for the design of their blades. In this research, XFOIL was used to develop and test three high performance airfoils (EYO7-8, EYO8-8, and EYO9-8) for small wind turbine application. The airfoils were subsequently used in conjunction with Blade Element Momentum Theory to develop and test 3-bladed 6 m diameter wind turbine rotors. The aerodynamic performance parameters of the airfoils tested were lift, drag, lift-to-drag ratio, and stall angle. At Re = 300,000, EYO7-8, EYO8-8, and EYO9-8 had maximum lift-to-drag ratios of 134, 131, and 127, respectively, and maximum lift coefficients of 1.77, 1.81, and 1.81, respectively. The stall angles were 12°for EYO7-8, 14°for EYO8-8, and 15°for EYO9-8. Together, the new airfoils compared favourably with other existing low Re airfoils and are suitable for the design of small wind turbine blades. Analysis of the results showed that the performance improvement of the EYO-Series airfoils is as a result of the design optimization that employed an optimal thickness-to-camber ratio (t/c) in the range of 0.85-1.50. Preliminary wind turbine rotor analysis also showed that the EYO7-8, EYO8-8, and EYO9-8 rotors had maximum power coefficients of 0.371, 0.366, and 0.358, respectively.

The lack of access to electricity in developing countries necessitates spatial electricity planning for guiding sustainable electrification projects that evaluate the costs of centralized systems vis-a-vis decentralized approaches. Heuristic approaches have been widely used in such electrification problems to find feasible, cost effective solutions; however, most of the time global optimality of these solutions is not guaranteed. Our thesis through its modeling approach provides a new methodology to find the least cost solution to this electrification problem. We model the spatial network planning problem as Prize Collecting Steiner Tree problem which would be base for a decision support tool for rural electrification. This new method is systematically assessed using both randomly generated data and real data from rural regions across SubSaharan Africa. Comparative results for the proposed approach and a widely used heuristic method are presented based on computational experiments. Additionally, a bi-objective approach that permits to take carbon emission level into the account is implemented and experimented with numerical data.
