What is a micro hydro power plant?
Micro-hydropower systems are small hydropower plants that have an installed power generation capacity of less than 100 kilowatts (kW). Many micro-hydropower systems operate “run of river,” which means that no large dams or water storage reservoirs are built and no land is flooded.
What is a microhydro generator?
Microhydro is considered to function as a ‘run-of-river’ system, meaning that the water passing through the generator is directed back into the stream with relatively little impact on the surrounding ecology.
Why is micro hydro important?
Because of the low-cost versatility and longevity of micro hydro, developing countries can manufacture and implement the technology to help supply much needed electricity to small communities and villages.
What happens if a site produces a large amount of energy?
If your site produces a large amount of excess energy, some power companies will buy back your electricity overflow. You also have the ability to supplement your level of micro power with intake from the power grid.
How far away can hydroelectricity be delivered?
Electricity can be delivered as far as a mile away to the location where it is being used.
What happens if you use the latest electronic control equipment?
The Truth: If the latest electronic control equipment, inverters and alternators are used, the resultant power supply has the potential to be of higher quality the main electrical power grid.
What are the factors to consider when considering a small stream?
Factors to consider are: distance from the power source to the location where energy is required, stream size (including flow rate, output and drop), and a balance of system components — inverter, batteries, controller, transmission line and pipelines.
How much does it cost to build a hydroelectric system?
Building a small-scale hydro-power system can cost from $1,000 – $20,000, depending on site electricity requirements and location. Maintenance fees are relatively small in comparison to other technologies.
Micro hydro power project design
The project described was intended to select a Pelton Wheel moving-water turbine and synchronous generator combination suitable for supplying electricity to a grid at a fixed voltage. The generator, driven by the turbine, operates at variable speed, and hence with varying voltage and frequency.
Outcome of the project
By implementing this set of hardware, software and PID algorithms, the project succeeded in demonstrating control and maximizing system performance under different upstream water flow and electrical load conditions. Its achievements can be listed more specifically:
A valuable contribution to sustainability?
Research projects like this, which facilitate the viability and efficiency of micro hydro power plants could contribute to a more sustainable future. At a casual glance, hydro power of any type may appear to be renewable and green – but it is not that simple. Large scale hydro plants create emissions due to construction and site traffic.

Impulse Turbines
Impulse turbines, which have the least complex design, are most commonly used for high-head microhydro systems. They rely on the velocity of water to move the turbine wheel, which is called the runner. The most common types of impulse turbines include the Pelton wheel and the Turgo wheel.
Reaction Turbines
Reaction turbines, which are highly efficient, depend on pressure rather than velocity to produce energy. All blades of the reaction turbine maintain constant contact with the water. These turbines are often used in large-scale hydropower sites.
Pumps and Waterwheels
Conventional pumps can be used as substitutes for hydraulic turbines. When the action of a pump is reversed, it operates like a turbine. Since pumps are mass produced, you'll find them more readily than turbines. Pumps are also less expensive. For adequate pump performance, however, your microhydropower site must have fairly constant head and flow.

Irrigation can be made to at least 20 hectares ( say, otherwise depends upon the discharge and head available) of land on the vicinity of the project site. The people of other places can also use electric pumps to irrigate their lands in a restricted manner to ensure that adverse effects will not be created to the ecology and sociology of the society.
Why are diesel units only available to the wealth?
The diesel units are only accessible to the wealth due to exorbitant rates. So one or two community controlled grinding units can be stated in the village which will in turn reduce the work load of the women-fold in addition to financial benefits.
Why is hydropower important?
Hydropower gives us a new resource for drinking water conservation. Because the water that gets stored in a dam is fresh (not salt water), it gives us a way to provide drinking water resources to nearby communities. Many cities around the world get their water from nearby streams and rivers.
How does hydropower work?
Hydropower provides the opportunity to generate electricity without the creation of greenhouse gas emissions after the installation of the facility. The concrete and other materials may create a significant investment, but it is also possible to create long-term power to create massive net savings.
How does hydropower affect Egypt?
1. Hydropower creates opportunities for political conflict.#N#The Renaissance Dam project on the. Nile River is sparking an ongoing dispute between Ethiopia’s developmental needs and water scarcity concerns in Egypt. Climate change is one of the primary drivers of this disadvantage, but there are also political issues to consider. Scarce resources and national boundaries create rights issues that can lead to potential conflict. Meetings have been so unproductive that neutral parties, including the United States, have been called in to mediate.
