Abstract
Electricity access in rural areas is a critical challenge for global electrification. Most countries have focused on increasing electricity coverage without assessing the long-term sustainability of such solutions. To achieve sustainability in rural electrification solutions, it is necessary to consider five dimensions: technical, environmental, economic, social, and institutional. This paper reviews the state of rural electrification worldwide and proposes a dynamic tariff scheme that increases the technical and economic conditions of implemented solutions over an extended period. The proposed time-of-use (TOU) pricing methodology aims to flatten the system demand curve and utilize on-site renewable energy potentials. For the methodology’s evaluation, we analyzed a case study focused on electrification in isolated areas of Colombia, conducting a sensitivity analysis of user-behavior to the proposed tariff scheme using the concept of price elasticity of demand. We also evaluated the effect of the achieved demand curve flattening on the system frequency. The identified benefits highlight that an accurate pricing scheme can reduce the variation range in the system frequency. Furthermore, the evaluation results show that the implementation of the proposed tariff scheme has the potential to significantly flatten the demand curve and encourage the connection of non-conventional renewable sources to improve network conditions.
