Pico-hydropower is a viable technology that can be integrated into a decentralized, off-grid approach to rural electrification in regions that currently have only limited access to electricity. The Turgo turbine is classified as an impulse turbine, similar to the Pelton wheel, often used in...

This paper describes the design of four different specific speed microhydro propeller turbines operating at heads between 4m and 9m, and their application to a wider range of heads and outputs by scaling. The features are specifically tailored for ease of manufacture and uniquely resistant to...

This paper describes the design of two different specific speed microhydro turbines operating at heads between 6 and 12m, at small scale and up to heads of 50m at larger scales. The features are specifically tailored for ease of manufacture and uniquely resistant to debris blockage. Test...

This paper presents an analysis for penstock optimization, for low head microhydro schemes. The intent of the optimization is to minimize capital cost per kilowatt rather than maximize the energy from the site. It is shown that site slope is an important consideration that affects the economics.
