Micro hydro, or small-scale hydro, is one of the most environmentally benign energy conversion options available, because unlike large-scale hydro power, it does not attempt to interfere significantly with river flows. Low Head Systems: One way to identify sites for small hydro power projects is to look for old water mill sites (or place names including the word “mill”). Environmental criteria are very important in deciding whether a site is suitable for hydro power. The environmental impacts associated with construction and possible alterations to the river environment should be minimal for a micro hydro power project if the scheme is well designed.
You will almost certainly require an abstraction and containment license for any hydro scheme. Costs and Maintenance: High head hydro systems have proved to be very reliable and can have a design life of 25 years or more.

Licence fees: A licence fee will be charged for any media (low or high resolution) used in your project.
Micro-hydro power is the small-scale harnessing of energy from falling water, such as steep mountain rivers.
Practical Practical Action promotes small-scale hydro schemes that generate up to 500 kilowatts of power. We have developed micro-hydro systems with communities in Peru, Zimbabwe, Sri Lanka, and Kenya.
For industrial use, the output from the turbine shaft can be used directly as mechanical power, as opposed to converting it into electricity via a generator or batteries.
Micro-hydro schemes are owned and operated by the communities they serve, with any maintenance carried out by skilled members of that community. Please donate to our essential work today, and support projects like this around the world. For a Sri Lankan school facing an energy crisis a small 'pico' hydro scheme installed with help from Practical Action has come to the rescue. The Tungu-Kabri micro-hydro power project in Kenya is an example of a cheap, sustainable and small-scale technology.


Our monthly e-newsletter, SmallTalk, provides regular updates on our work around the world. With a regular or single gift, you can support our work with poor people in developing countries. Practical Action uses technology to challenge poverty, working with poor women and men around the world.
Hydropower is a well-proven technology, relying on a non-polluting, renewable and indigenous resource, which can integrate easily with irrigation and water supply projects. The amount of energy produced by a hydro power scheme depends on how far the water is falling (called head) and the flow rate (i.e. Some of the water flowing along a watercourse is re-directed into the intake which screens for debris and fish to prevent them entering the turbine. Usually the highest cost in Hydro power development is the building work needed to house the turbine appropriately and redirect water from the river through the turbine, and old mill sites may have some of the building work in place already.
Costs vary due to a range of factors such as length of penstock, size of turbine and geographic location.  Hydro systems generally require very little maintenance other than ensuring they are kept relatively clean and checking that the amount of flow in the watercourse is not at a low level (thus affecting your license to use the water). Please use the navigation menu to find a list of local, accredited (Low Carbon Buildings Programme) installers. The micro-hydro station, which converts the energy of flowing water into electricity, provides poor communities in rural areas with an affordable, easy to maintain and long-term solution to their energy needs.
These systems, which are designed to operate for a minimum of 20 years, are usually 'run-of-the-river' systems.
Instead they divert water from the stream or river, channel it in to a valley and drop it in to a turbine via a pipeline called a penstock.
By not requiring an expensive dam for water storage, run-of-the-river systems are a low-cost way to produce power.
People can use these convenient sources of electricity to fuel anything from workshop machines to domestic lighting - and there are no expensive connection costs.
This is suitable for agro-processing activities such as milling, oil extraction and carpentry. So they provide employment in themselves, as well as providing the power to re-energise entire communities. If you require further details regarding the transaction data, please contact the supplier directly.


From the intake the water then leads into a channel or pipe (called the penstock) where it falls down through one or more turbines.
Although it is possible to use existing waterwheels to generate electricity it can be expensive and inefficient due to the gearing required to get the low revolutions per minute (rpm) of the waterwheel to the much higher rpm required by the electricity generator.
The EA recognises the potential benefits of small-scale hydropower to rural communities and in meeting local needs for power, but by their nature, hydropower proposals often require the EA to balance the requirements of developers with protection of the environment. If you do not own the land ensure that you have written consent from a landowner and that your consent has been checked by a legal professional.
It can generate 25 Kw of electricity and with the feed in tariff for renewable energy generation should make the owner around 25,000 per year.
They also avoid the damaging environmental and social effects that larger hydroelectric schemes cause, including a risk of flooding. The batteries are charged at a station in the village, thus providing the local community with a clean, renewable source of power.
The water passing through the turbines generates electricity and is returned to the river afterwards. Where a proposed scheme is inappropriate for its location the EA will advise a prospective developer at as early a stage as possible. High-head sites, especially in the Brecon Beacons, can have up to several hundred metres of head. It will take a positive view of reasonable and well designed proposals for hydropower schemes and will work with developers and others in attempting to agree a viable, sustainable project. We advise that you consult with an accredited installer and develop detailed designs of the project before seeking planning permission. There is huge potential for small scalehydro projects in the Lake District, and other upland areas of the UK. The National Park Authority Planning Department view hydro installations favourably, but they will require detailed drawings of your proposal. We recommend that you contact them first of all to ensure that they have no major concerns with your particular watercourse, but you will be required to have access and planning permissions already granted for the EA licences to be approved.
