Run of the river hydroelectric systems are hydroelectric systems that harvest the energy from flowing water to generate electricity in the absence of a large dam and reservoir which is how they differ from conventional impoundment hydroelectric facilities A small dam may be used to ensure enough water goes in the penstock and possibly some storage for same day use The primary difference

Voila hydro potential At the driest time of year our creek measures about 3 feet wide by 3 4 inches deep and a five gallon bucket and stopwatch suggested we had over 300 gpm flowing past our intake site Wow lots of potential With 80 feet of drop a nozzle flow chart indicated we could theoretically pass 134 gpm through a Harris 4 nozzle

Hydropower is still used as a source of electricity in the United States Using the same concepts from your experiment water wheels capture the force of powerful rivers converting it into electricity and sending it into the electrical grid Hydropower is an example of renewable energy energy that can be continually replenished What other
Homestead Hydro Part 1 Many farms ranches and other fair sized tracts of land embrace at least one brook within their limits In most cases the idea that a small stream can provide a useful
By 1900 hundreds of small hydropower plants were in operation as the emerging technology spread across the world In China in 1905 a hydroelectric station was built on the Xindian creek near Taipei with an installed capacity of 500 kW A century of rapid changes
Microhydropower Systems Microhydropower can be one of the most simple and consistent forms or renewable energy on your property If you have water flowing through your property you might consider building a small hydropower system to generate electricity Microhydropower systems usually generate up to 100 kilowatts of electricity
Table 1 Classification of small hydropower by size kW Kilowatt = 1000 Watts MW Megawatt = 1 000 000 Watts or 1000 kW Small hydro 115 MWusually feeding into a grid Mini hydro from 100 kW up to 1 MW either stand alone schemes or more often feeding into the grid Micro hydro

Fun Facts about Hydropower There are over 2 000 hydroelectric power plants in the United States Many countries such as Norway and Brazil get a significant portion of their electricity as much as 85 from hydropower The largest dam and hydroelectric power plant in the world is the Three Gorges Dam in China It provides 22 500 Megawatts of
The two vital factors to consider are the flow and the head of the stream or river The flow is the volume of water which can be captured and re directed to turn the turbine generator and the head is the distance the water will fall on its way to the generator The larger the flowi e the more water there is and the higher the headi e the higher the distance the water falls
The Smart Hydro Power turbine was developed to produce a maximum amount of electrical power with the kinetic energy of flowing waters Because it is powered by kinetic energy instead of potential energy it is known as a so called zero head or in stream turbine As such no dams and/or head differential are necessary for the
