Micro-hydropower in the United States

An assessment study of the interest and problems relating to the development of micro-hydropower, i.e., capacities of less than 100 kW, was completed in December 1980 under DOE sponsorship. A total of 62 individuals from 10 states and 4 groups, i.e., developers, A/E firms, equipment manufacturers, and state and federal agencies, were polled to determine their perceptions of the advantages and disadvantages of micro-hydro developments and the needs for such developments. Financing, technical assistance, and help with the economic analysis and regulatory aspects of micro-hydro development appeared to be the paramount needs. Whether or not a specific site can be successfully developed depends on site conditions. A micro-hydro plant discussed as an example is shown to be a poor investment, e.g., maximum $200 per month return on $60,000 investment.
