    Analytical Frameworks and an Integrated Approach for Mini-grid based Electrification
    (Springer, 2014-01-31) Bhattacharyya, Subhes; Mishra, A.; Sarangi, G. K.
    Although rural electrification using mini-grids has attracted recent global attention, the concept has been there for quite some time. Consequently, a number of analytical approaches exist to support the decision-making process. This chapter first provides a review of literature dealing with analytical frameworks for off-grid and mini-grid based electrification projects. The range of analytical options includes simple worksheet-based tools to more sophisticated optimisation tools for technology selection as well as assessments based on multicriteria analysis. This is followed by an evaluation of mini-grid based off-grid electrification projects in India that allows the identification of critical factors for the success of such projects. Finally, the chapter proposes an integrated approach for analysing decentralised mini-grid projects in a holistic manner.

    Poverty Amidst Plenty: Renewable Energy-Based Mini-Grid Electrification in Nepal
    (Springer, 2014-01-31) Sarangi, G. K.; Pugazenthi, D.; Mishra, A.; Palit, D.; Kishore, V.V.N.; Bhattacharyya, Subhes
    Providing access to electricity to a large section of rural population in Nepal has traditionally been a challenging exercise. This has been exacerbated by difficult geography, poor-socio-economic profile of rural Nepal and moreover by the on-going energy crisis. This chapter conducts an objective assessment of the renewable energy-based off-grid electricity sector in Nepal, with specific focus on micro-hydro-based mini-grid systems by applying a mixed method research design built on both qualitative and quantitative research techniques. While the country’s experiences of developing micro-hydro- and solar energy-based off-grid interventions are captured by qualitative analysis, a standard techno-economic analysis of a micro-hydro mini-grid project is conducted to explore the possibility of introducing additional productive loads and to examine the cost efficacy of generating energy from micro-hydro vis-à-vis solar. Assessment of off-grid electrification options reveals that despite visible progresses, there still exist multiple roadblocks to scale up. Absence of clearly spelt out policy goals, weak institutional designs, low load factors, and lack of adequate finance and overall regulatory concerns stand as major obstacles for off-grid electricity sector development in the country. In addition, project-specific analysis reveals that solar loses out as a cost-effective option compared to micro-hydro. But optimal use of energy generated from micro-hydro-based mini-grids requires creation of productive applications at the local scale on a sustainable basis.

    Replication and scaling-up of isolated mini-grid type of off-grid interventions in India
    (AIMS Press, 2016-02-25) Pugazenthi, D.; Sarangi, G. K.; Mishra, A.; Bhattacharyya, Subhes
    Providing basic minimum energy services has become a real challenge for developing countries of the world. India encounters the problem of provisioning basic minimum electricity services to a section of her population. Renewable energy-based decentralised systems have emerged as a viable electrification option for many developing countries of the world, particularly for rural and remote areas of the country. This study explores the replication and scaling-up of potential of such mini-grids in the least electrified states of India by considering a set of evaluation criteria i.e. grid-extension option, renewable energy resource potential, electrification rate, organisational strength, presence or absence of technical support system, and ease of access to banking services. Overall rankings suggest that top 20% districts offer good business potential for private investors to venture into the mini-grid market. However, the concern lies with the districts placed at the bottom, which require specific government interventions through appropriate policy, regulatory and financial support.
