Mini Grid Solutions for Underserved Customers

New Insights from Nigeria and India

By: Bernard Tenenbaum,Chris Greacen,Ashish Shrestha

TRaditionally, mini grids have been viewed as “off-grid†? systems that are built and operated solely for communities without electricity. The reality, however, is that millions of people in Sub-Saharan Africa and India who are connected to the main grid suffer from poor grid reliability (“weak grid†?), sometimes with a power supply of less than 4 to 8 hours daily and with frequent disputes over the accuracy of billing. As a backstop, these poorly served customers often find themselves forced to rely on small fossil fuel†“powered generators that are noisy, polluting, and expensive to operate. Mini Grid Solutions for Underserved Customers: New Insights from Nigeria and India explores another option: undergrid mini grids. These are mostly solar hybrid†“powered mini grids built and operated by private companies in areas already connected with the main electricity grid but facing poor technical and commercial service. This comprehensive book examines how undergrid mini grids can create win-win-win outcomes for retail customers, distribution enterprises, and mini grid developers. Drawing on extensive discussions with pioneering developers, the book showcases detailed case studies from Nigeria and India, shedding light on the challenges and opportunities of interconnected and non-interconnected undergrid mini grids. The authors address technical issues of grid interconnection and delve into the policy and regulatory considerations crucial for the financial sustainability and success of undergrid mini grids. The book is an invaluable resource for policy makers, energy practitioners, and researchers seeking practical insights to bridge the electricity access gap, empower communities with reliable and affordable electricity, and drive environmentally and commercially sustainable development. • “The report is rich with insight, not least because the authors have been able to contrast the Nigeria and India approaches taken by the respective private sectors in each country. The five case studies are very valuable. The authors have powerfully illustrated the importance of the policy and regulatory framework and how that translates into investor behavior.†? — Mohua Mukherjee, Senior Research Fellow, Oxford Institute of Energy Studies • “This great report represents a pivotal turning point in the history of energy and has global implications for the role of mini grids for communities that have been poorly served by main grid utilities.†? — Peter Lilienthal, Founder HOMER Energy • “This is a tremendous addition to the literature on mini grids and an important guide for all of us practitioners working in this area.†? — James Sherwood, Director of Research & Innovation, RMI | Global South Program • “This refreshingly honest and open report provides an excellent overview of interconnected and isolated mini grids, as well as a thorough analysis of key ground-level implementation issues in regulation, business, and engineering.†? — Joanis Holzigel, Chief Operating Officer, INENSUS

Introduction To Hydraulics Of Fine Sediment Transport, An (Second Edition)

By: Ashish J Mehta

This book expounds the hydraulics of fine sediment which is almost ubiquitously found in coastal and estuarine waters, and in rivers, lakes, and reservoirs. Although the basic subject may be categorized as applied marine physics in shallow waters, several physicochemical and biological effects on particulate transport have been addressed.In this second edition most of the chapters have been substantially updated, rewritten, and expanded. Overall, a significant change has also been made throughout by replacing sediment concentration, a unit dependent quantity at the heart of numerous descriptions, measurements, and calculations, with the nondimensional sediment volume fraction. It marks a divergence in the manner in which fine sediment transport data and calculations are conventionally presented.The book is mainly written for civil engineering seniors and graduate students, to offer a comprehensive foundation in hydraulics of fine sediment. The book is also a useful reference for researchers interested in the effects of physical chemistry and biology on fine sediment transport in water and to an extent on coastal and estuarine morphodynamics, sediment transport, port and harbor engineering, and applied shallow watwer marine physics. The book is also recommended reading for those interested in understanding particle transport in water.Related Link(s)

An Introduction To Hydraulics Of Fine Sediment Transport

By: Ashish J Mehta

This book presents observations on the phenomena of fine sediment transport and their explanations under process-related divisions such as flocculation, erosion, and deposition.The text is a compilation of the author's lecture notes from nearly four decades of teaching and guiding graduate students in civil and coastal engineering. Illustrations of fine sediment transport processes and their complexities given in the book are taken from field and laboratory-based observations by the author and his students, as well as numerous investigators.The wide-ranging composition of particles (of inorganic and organic matter), their universal presence and their complex interactions with hydraulic forces make this branch of science a difficult one to deal with in a single treatise. It is therefore essential to study fine sediment transport as an independent subject rather than cover it in no more than a single chapter as many texts on coarse sediment transport have done.Even though the entire coverage is “introductory”, the twelve chapters collectively include more material than what can be reasonably dealt with in a one semester, three-credit course.The book includes an extensive description of the components of fine-grained — especially cohesive — sediment transport. It covers the development of the subject in scientific and engineering applications mainly from the 1950s to its present state. Solved examples and chapter-end exercises are also included.This text is aimed at senior civil engineering undergraduates and graduate students who, in the normal course of their study, seldom come across the subject of fine sediment transport in their curricula. Interested students should have a basic understanding of the mechanics of fluid flow and open channel hydraulics.

Fiber Crop-Based Phytoremediation

Socio-Economic and Environmental Sustainability

By: Pooja Mahajan,Purabi Saikia,Ashish Praveen,Vimal Chandra Pandey

Fiber Crop–Based Phytoremediation: Socio-economic and Environmental Sustainability provides an informative source of information on using fiber crops for phytoremediation. Phytoremediation is gaining attention globally due to ever-increasing numbers and areas of industrially polluted sites. The major challenge is to develop new and cost-effective solutions to decontaminate polluted sites. In this regard, plant-based remediation, especially using fiber crops, is a promising and cost-effective approach for environmental remediation on a large-scale due to its socio-economic and ecological sustainability. Furthermore, changing environmental conditions also cause various biotic and abiotic stresses in fiber crops and thereby negatively affect the fiber crop establishment, growth and yield.This book will be specifically important to these readers who need to be able to select specific fiber crop species according to site-specificity of the contaminated site. - Provides up-to-date research and understanding on how to utilize fiber crops for the phytoremediation of contaminated land - Covers a wide range of applicable fiber crops, including bast, grass and woody crops, allowing for the utilization of techniques regardless of specific fiber crop - Details the uses and benefits of fiber crop phytoremediation on environmental, societal and economic development

Planning, Design and Optimization of Distribution System for Affected Area of Upper Karnali Hydropower Project

By: Ashish Shrestha

Master's Thesis from the year 2017 in the subject Engineering - Mechanical Engineering, grade: 4, Kathmandu University (School of Engineering), course: Masters' Program in Planning and Operation of Energy System, language: English, abstract: This study illustrates the best approach for energy access to the affected area of a 900 MW Upper Karnali Hydropower Project (UKHPP) located in Western Nepal. As per concession agreement executed between the developer of UKHPP and the Government of Nepal, the developer will develop 2 MW power plant at the toe of the dam using the environmental release discharge to electrify the affected area of UKHPP. First, the study looks at the optimization of the electric grid network in the project affected area, using Kruskal’s algorithm. The optimization is carried out so that access to electricity is guaranteed to possible load centers in the affected area to the extent possible in technical and financial feasible manner. This study is an attempt to connect the possible load centers through an optimum network design based on demography, topography, technical feasibility and socio-economic factors. The study focuses on the design of the electrical network based on a least distance path between the identified nodes. The designed network is based on the survey using GIS, Topographical maps, and satellite views from Google map. A total of 57 load centers are identified connected through a grid 144.59 km in length. Similarly, taking n=4 sample, the total length of 220V distribution system is estimated to be 417.24 km. After that, the study focuses on the Static Load Flow Analysis (SLFA) by developing a framework based on Conventional Newton- Raphson method to analyze the network’s parameters. The result obtained from the analysis is compared with the results of standard 33-bus radial feeder system and forward/backwards (f/b) sweep based algorithm using statistical analysis. The standard error is accepted for the 95% level of significance. It is concluded that, the load flow analysis (LFA) of the primary distribution in this study conducted using the N-R method was adequate and best fit for a grid-like network with medium voltage level. The estimated losses are low and under the limit (i.e. 2.04%) which shows that the designed system performs adequately. From the analysis, it is found that, the pre-defined generation of 2 MW power is insufficient to electrify the whole affected area of the UKHPP. Different alternative ways are recommended to manage the load and provide electricity to the people of the affected area.

What is Man?

Selected Writings of Sri Madhava Ashish

By: Sri Madhava Ashish

For anyone who has wondered ‘What is life all about? Why are we born? And does it all just end with death?’ the essays in this anthology provide profound answers. The author, Sri Madhava Ashish, was for many years the head of a remote and rather unconventional ashram in the Himalayan foothills of northern India. The ashram drew visitors from India and all over the world—people driven by just such questions about ultimate meaning and purpose. The distilled teaching that Ashishda, as he was fondly known, offered freely and that forms the core of these essays, is intensely relevant to our lives today. It has little to do with conventional religions, but can be called secular spirituality. It points out the folly of viewing the cosmos in material terms alone, encouraging us to open our minds and see that our lives are not restricted to the closed box of purely physical existence. Sri Madhava Ashish urges us to set out on the most urgent of all quests: the path of self-knowledge that integrates timeless inner practices—such as meditation—with a meaningful and active outer life. Using methods that include intelligent inquiry, psychological self-examination and dream analysis, his unorthodox teaching provides a road-map for the emotions, the intellect and the soul to develop in harmony—so that both individuals and society can free themselves from egoism, violence and greed, and begin to base their values on the reality of their spiritual source.
