Intro to Hydropower - Measuring Head and Flow
Small-scale hydro is the only renewable energy source that works for you 24 hours a day, 7 days a week. In the first article in this series (HP103), I explained the basics of hydroelectric system theory, and reviewed system components. This article focuses on measuring a stream’s head and flow. Before you can begin designing your hydro system or estimating how much electricity it will ...

An assessment of reservoir filling policies for the Grand Ethiopian Renaissance Dam
Africa's largest hydropower facility is currently under construction on the main stem of the Blue Nile River in Ethiopia. The Grand Ethiopian Renaissance Dam (GERD) is poised to facilitate regional development with a 63 billion cubic meter reservoir and 6,000 MW of power generating capacity. To date, however, no reservoir filling rate policy has been established. This policy will have ...

Power estimation and reliability evaluation of municipal waste water and self–excited induction generator–based micro hydropower generation system
This paper presents power estimation and reliability evaluation of the micro hydro power generation system based on municipal waste water. Self–excited induction generator was used in the developed power plant, situated at IIT (BHU) campus, Varanasi, India. The hydro potential of the waste water flowing through sewage system of the Banaras Hindu University has been determined for annual flow ...

Intro to Hydropower Part:2 Measuring head & flow
Measuring the stream course—Anna and Joe work downstream, shooting vertical drop (head) with a sight level, and getting a rough measurement of the pipe run at the same time. Small-scale hydro is the only renewable energy source that works for you 24 hours a day, 7 days a week. In the first article in this series (HP103), I explained the basics of hydroelectric system theory, and reviewed ...

How to make hydropower more environmentally friendly
Hydropower provides 85 percent of the world’s renewable electricity, but comes with a hefty environmental price tag. Here’s what some are doing to fix that. Humanity got its first large-scale electricity thanks to hydropower. On Aug. 26, 1895, water flowing over Niagara Falls was diverted to spin two generators, producing electricity to manufacture aluminum and carborundum. Since ...
