“…Despite the promising potential of renewable mini-grids, several gaps remain in the literature on how to correctly size these systems throughout their lifetime to serve communities currently lacking energy access. Notably, realistic electricity demand assumptions are uncertain (Ortega-Arriaga et al 2021) and there is a lack of measured data on the utilisation of mini-grids and how this changes and grows over time (Blodgett et al 2017, Prevedello andWerth 2021). Thus, it is challenging to forecast the current and future demand of unelectrified communities, which in turn affects mini-grid design and financial feasibility Dauenhauer 2016, Blodgett et al 2017).…”

Mini-grids are a critical way to meet electricity access goals according to current and projected electricity demand of communities and so appropriately sizing them is essential to ensure their financial viability. However, estimation of demand for communities awaiting electricity access is uncertain and growth in demand along with the associated cost implications is rarely considered during estimation of mini-grid sizing. Using a case study of two rural communities in India, we assess the implications of demand growth on financial costs and performance of a mini-grid system consisting of solar photovoltaic (PV) panels and battery storage using two different system sizing approaches. We show a cost-saving potential of up to 12% when mini-grids are sized using a multi-stage approach where mini-grids gradually expand in several stages, rather than a single-stage optimisation approach. We perform a sensitivity analysis of the cost of the two sizing approaches by varying six key parameters: demand growth rate, logistics cost, system re-sizing frequency, likelihood of blackouts, solar PV and battery cost, and degradation rate. Of these, we find that system costs are most sensitive to variations in demand growth rates and cost decreases in solar PV and batteries. Our study shows that demand growth scenarios and choice of mini-grid sizing approaches have important financial and operational implications for the design of systems for rural electrification.

“…Electrification via off-grid focuses on the economic aspects in terms of financial sustainability [3]. Many rural electrification projects have failed due to lack of attention to the issues beyond financial and technical dimensions [4]. Real data from an off-grid microgrid in the Philippines were analyzed and used for simulating different sharing scenarios and presents a combined approach applying geospatial analysis, cluster analysis and energy system modelling [5,6].…”

Rural electrification in the Philippines is one of the main problems in the country. In this study, the possible electrification of Barangay Puray using three alternatives, namely, solar power, generator set and Meralco connection was analyzed. The stakeholders in this study were the people of the barangay, the local government of Rizal and the Meralco Corporation. Some assumptions are made, one of which is that the local government of Rizal will pay the capital costs for solar power and generator set, while the residents of the barangay will pay the government within 25-year period of the study. Here, two cases were introduced, whether the residents will pay the capital and maintenance costs or the maintenance costs only. The values of the initial costs and maintenance costs were compared and used to get the generation cost of the system. The results showed different values, with total of 189,889,720 pesos for the solar power while for the generator set was 235,425,304 pesos, thus the conclusion was made for the perspective of each of the stakeholder. For the residents of Barangay Puray, the most feasible was the solar power utility system. For the local government of Rizal, the generator set was more advantageous. While the Meralco Corporation would need the road laid out first before the electrification even it only has capital cost of 10,721,984 pesos in which the MOE was disregarded.
