Micro-Scale Hydropower for the Eighties

Caicedo-Maddison, E. Beatriz 01 January 1982 (has links) (PDF)
The objectives of this project are to show the feasibility of micro-hydropower and to provide adequate engineering data for those people who wish to design their own micro system. Nine case studies are reviewed and analyzed in an attempt to determine general design parameters. Comparative data for these studies comes from preliminary permit applications submitted to the Federal Energy Regulatory Commission. Information on such topics as flow measurements, heads, generators and turbine technology are presented. Duration curves are explained with examples using data from a river found in Colombia, South America. Finally, a preliminary design of a micro-hydro facility is calculated for implementation on a stream that is part of the Tennessee River Basin.

Small Scale Hydropower-Appropriate Technology for Rural Development in Lesser Developed Countries

Harper, Stephen R. 01 July 1980 (has links) (PDF)
Less Developed Countries (LDC's) now have a total of about 2.8 billion people, or approximately 70 percent of the total world population. World populations and current energy consumption are such that is all the world's countries came up to the U.S. per capita energy use, the world's consumption would multiply by a factor of seven. For the LDC's, energy development will be an increasingly important issue. Hydropower technology is on the shelf, and available now, of proven feasibility both technically and economically, and presents a sound and rational energy solution from the environmental viewpoint. It is a technology which could be useful to the Less Developed Countries for the long term, irrespective of the shift from abundant low-cost fossil fuel options or the development of more exotic alternate energy technologies. With its continuing replenishment and nondepleting characteristics, it remains one of the most attractive sources of energy. The nature of water resources includes a distributive element which makes it ideal for rural development. The apparent shift in development policy, from the traditional "top-down" industrialization approach to the "bottoms-up" reach the village approach, requires decentralized applications of energy resources attainable through development of hydropower in many regions of the world. Distributed Small Scale Hydropower (SSH) systems offer excellent opportunities to augment energy supplies to many rural areas. Also, in a modest way the development of a community infrastructure, training of operating and maintenance personnel, and initiation of small scale agribusiness enterprises may be undertaken. Each of these activities could result in relatively major contributions to the improvement of quality of life. SSH sites are found in abundancy in most mountainous regions and offer sensible possibilities for decentralized applications in LDC's.

The economic and policy aspects of small hydro development in British Columbia

Croll, Geoffrey Edward George January 1990 (has links)
Small hydropower offers many advantages as a source of energy and it has been successfully developed by the private sector in the U.S. and in Ontario. Although there is considerable interest in developing British Columbia's vast small hydro resource, there has been very little progress to date. The reasons for this are related more to economic and political factors than to technical issues. In this thesis I review the situation in B.C. and propose a policy framework for energy purchase price, one of the main issues involved in small hydro development. The price offered small hydro producers for their electricity is clearly less than B.C. Hydro's avoided cost, but there is little evidence to support the amount offered. I suggest that, in the absence of an established, competitve market, energy purchase rates should be based on the utility's avoided costs, and that avoided costs be determined by amortizing the capital costs of the next scheduled project over a 20 year period, rather than basing them on the average levelized costs of all future projects. Furthermore, small hydro development should take a two-stage approach, similar to Ontario's, whereby energy is initially purchased at the utility's full avoided cost and later, when the small hydro industry has had a chance to develop, energy would be purchased at market value or through a competitive bidding process. / Applied Science, Faculty of / Civil Engineering, Department of / Graduate
