Solar microgrids in rural India: A case study of household benefits

Abstract

This study evaluates the benefits that rural households in India derive from dedicated solar microgrid service systems. A case study was conducted in Lakshmipura-Jharla, Rajasthan, a village in western India with significant potential for producing solar energy. In 2013, a private investor set up a solar microgrid in the village and distributed energy-efficient appliances. Its goal was to give poor households access to modern energy services. The study data were collected through a survey conducted among randomly selected households in the village. The survey found that such an electricity provision service had multidimensional benefits: flexible use of the energy service, more effective time allocation among women, more study time for students, improved indoor air quality, and safer public places. Given the initial unmet demand for modern energy in the village, technological interventions supported by policy has helped to expand consumption possibilities and new demand for services has emerged. The household-level frontier rebound effect is estimated to be more than 100%, reflecting a one-and-a-half times increase in the demand for illumination services among rural households. Frontier rebound effect estimates help quantify the benefits of solar microgrids and energy-efficient appliances for households in rural areas. The results of this study are consistent with existing literature that suggests that efficient appliances and access to electricity will increase the energy demand manifold and satisfy the growing and largely unmet demand for energy.
