An essential addition to the Earthscan Planning & Installing series, Planning and Installing Micro-Hydro Systems provides vital diagrams, pictures and tables detailing the planning and installing of a micro-hydro system, including information on the maintenance and economics once an installation is running. The book covers subjects such as measuring head and flow, ecological impacts, scheme layouts, practical advice, calculations and turbine choice. Archimedes screws are also covered in detail, as well as the main conventional choices relevant to small sites. Micro-hydro refers to hydropower systems with a power rating of 100kW or less. A 100kW system will produce 100 standard units of electricity in one hour. These systems have been popular in some sparsely populated or mountainous countries for a number of years, but now new technology, less stringent regulation of grid connected generators and standardised turbine designs are encouraging more widespread interest in micro-hydro in the developed world. The renewable energy sector is growing at a remarkable rate, and whilst much attention has so far focused on solar and wind technologies, Europe and elsewhere have great potential for generating power from small scale hydroelectric installations. This book is aimed at site owners, designers and consultants who are looking to develop schemes in the micro-hydro scale – 5 to 100kW – although the concepts are applicable to smaller and larger schemes.

Small Hydroelectric Engineering Practice is a comprehensive reference book covering all aspects of identifying, building, and operating hydroelectric schemes between 500 kW and 50 MW. In this range of outputs there are many options for all aspects of the scheme and it is very important that the best options are chosen. As small hydroelectric schemes are usually built against a limited budget it is extremely important that the concept design is optimum and every component is designed to maximise the benefi t and minimise the cost. As operating costs are often a high proportion of the income it is very important to make sure that everything is designed to be simple, reliable and long lasting. The book is based on the experience gained over 45 years on the overall and detailed design, construction and commissioning of more than 30 small hydropower schemes. It includes contributions from experts in the field of intakes, water diversion structures, geology, canals, painting and other aspects of hydropower development. It is intensely practical with many drawings and photographs of schemes designed and commissioned by Leyland Consultants and others. There are also sections on preparing specifi cations, tender assessment and operation and maintenance. The book includes a CD with spreadsheet programs for analysing aspects of small hydropower development and many arrangement drawings and detail designs for gates, penstocks, electrical systems and control systems. Typical specifi cations for generating plant are also included. The spreadsheets will be useful during the feasibility stage and the drawings will enable designers to scale the designs as needed for their own projects. Consultants, developers, designers, builders and operators of small hydroelectric schemes will find this book invaluable..

Small hydro power installations have the potential to provide a renewable supply of energy to people in remote, hilly communities, far from the national grid. This book is based on the authors' considerable experience of installing hydroelectric schemes that produce up to 500 kW for powering small communities. It describes not only the electro-mechanical equipment and how it is installed, but also the correct siting of the installation and how to design and build the channels leading up to the turbine so as to optimize performance. These civil works can be carried out by local manpower, using materials that are usually available locally. Chapters cover the main components of small hydroelectric plants from the intake and the headrace channel, via the conveyance channel, to the forebay tank, penstock, turbine, and generator. Designing and Building Mini and Micro Hydropower Schemes is essential reading for engineers, NGO managers and consultants planning and implementing micro hydro schemes. `This book's strength is that it is based on years of experience out in the field of designing micro hydro systems that work.' Dr Arthur Williams, School of Electrical Electronic Engineering, The University of Nottingham, UK `For remote communities lucky enough to live near hill streams or rivers, micro-hydro power is the most cost effective way of generating electricity. And it is clean energy. But it takes years of experience and skill to design the weirs, canals and spillways that are needed. Experienced practitioners take you through the whole design process, with drawings and calculations, so that anyone with good practical building skills can learn enough from the many years of knowledge crammed into this instruction book to build a solid scheme, without over-spending.'

Micro-Hydro Design Manual has grown from Intermediate Technology's field experiences with micro-hydro installations and covers operation and maintenance, commissioning, electrical power, induction generators, electronic controllers, management, and energy surveys.There is an increasing need in many countries for power supplies to rural areas, partly to support industries, and partly to provide illumination at night. Government authorities are faced with the very high costs of extending electricity grids. Often micro-hydro provides an economic alternative to the grid. This is because independentmicro-hydro schemes save on the cost of grid transmission lines, and because grid extension schemes often have very expensive equipment and staff costs. In contrast, micro-hydro schemes can be designed and built by local staff andsmaller organizations following less strict regulations and using 'off-the-shelf' components or locally made machinery.

More than two billion people worldwide have currently no access to grid electricity or other efficient energy supply. This is one third of humanity and the majority live in rural areas. The productivity and health of these people are diminished by reliance on traditional fuels and technologies, with women and children suffering most. Energy is the key element to empower people and ensure water, food and fodder supply as well as rural development. Therefore access to energy should be treated as the fundamental right to everybody. Renewable energy has the potential to bring power, not only in the literal sense, to communities by transforming their prospects. This book offers options that meet the needs of people and communities for energy and engage them in identifying and planning their own provision. It describes updated renewable energy technologies and offers strategies and guidelines for the planning and implementation of sustainable energy supply for individuals and communities.

The role of small hydropower is becoming increasingly important on a global level. Increasing energy demand and environmental awareness has further triggered research and development into sustainable low-cost technologies. In developing countries, particularly in rural areas, the possibility of local power generation could considerably improve living conditions. With this in mind, the development of a next generation low-head hydropower machines was subject of investigation in the EU-project HYLOW. Being part of the research lines of that project, this thesis presents a numerical modelling approach to improve the design of machines like water wheels for increased hydraulic efficiency. Nowadays, Computational Fluid Dynamics (CFD) enables numerical models to be quite accurate and incorporate physical complexities like free surfaces and rotating machines. The results of the CFD simulations carried out in this research show that a change in blade geometry can result in higher torque levels, thereby increasing performance. Numerical simulations also enabled to determine the optimal wheel-width to channel-width ratio and further improve performance by modifying the channel bed conditions upstream and downstream of the water wheel. With a power rating in the low kilowatt range, low-head hydropower machines like optimised water wheels seem to have a clear potential for small-scale energy generation, thereby contributing to achieving the Sustainable Development Goals by providing local energy solutions.

Hydro-Power: The Use of Water as an Alternative Source of Energy deals with the use of water as an alternative source of energy. The principles of the technology involved in the extraction of energy from water for use in some other form are discussed, and some of the projects that are being undertaken in a number of countries are described. Comprised of 12 chapters, this book begins with an overview of global energy consumption and projections for energy demand, along with electricity generation using hydraulic resources and developments in the use of hydroelectric power. The next chapter focuses on the principle of wave power as an energy source, with emphasis on how power can be derived from the slow oscillation of the waves; the economics of wave power; structural design of wave energy converters; and mooring considerations. Subsequent chapters explore national wave power programs in countries such as the United Kingdom, Japan, South Africa, Egypt, Mauritius, Norway, Sweden, and the United States; tidal power and hydrogen; and energy storage and hydroelectric schemes in Europe. The final chapter assesses the environmental impact of hydroelectric power. This monograph will be a useful resource for experts and policymakers in the field of energy as well as those with little knowledge of the potential contribution that water can make to the world's energy needs.
