Choosing a Turbine to Generate 5KWh from a Waterfall, River or Stream

Generating electricity from a river or waterfall can be a great way to access sustainable energy more reliably than solar or wind, and all year round. Effective power generation requirements vary from case to case.  Consider the different types of turbines available and their specific application. This guide discusses the three main types of turbines suitable for generation: Pelton wheel, Francis turbine and Kaplan turbine. It is hard to provide guidance on commercial products that would work best for each system configuration because of lack of supply and constantly fluctuating prices.  If you are a supplier or a customer with useful experiences, please leave details in the comments including URLs. However, the info below gives all you need to search out products in your own area.

Why generate 5KW from a waterfall or river?

Hydroelectric power generation has been around for centuries, but the latest technologies are more efficient, allowing greater amounts of power to be generated with less impact on the environment. Hydroelectricity is clean and sustainable energy, and more cost-effective than traditional sources such as coal-fired plants or petrol generators. Not only does this reduce carbon footprint, it also takes advantage of one of nature’s most abundant resources: running water. Harnessing the power of rivers and waterfalls offers benefits in terms of reducing air pollution from burning fossil fuels as well as providing local jobs installing and maintaining these systems. With careful planning, 5KW turbines can not only provide enough energy for homes and businesses but can also feed excess electricity to neighbours (or into the grid).

The best turbine to generate 5KWh from a waterfall or river

The choice of turbine will depend on the specific conditions of the site, in particular water flow rate and head.  Water flow is how much water passes through the hydro plant, and head refers to water pressure -ie how hard/quickly it flows. In general, Pelton wheel turbines are ideal for high head sites with lower flow rates, whereas Francis turbines are better suited for medium-head sites with higher flow rates. The Kaplan turbine is suitable for low head/high flow applications although it tends to be less efficient than other types of turbines due to its complex design.

Pelton wheel: best suited for high head, low flow applications

The Pelton wheel turbine is  the most popular type of turbines for hydroelectric power and likely to be the least expensive. It is suitable for high head and low flow applications, where the water pressure is greater than the flow rate. It works by using a series of buckets or cups which capture and redirect the water’s kinetic energy as it passes through them to spin a shaft connected to an electric generator. You will also need to buy a generator like this one. The buckets are angled in such a way that they capture more force from each wave as it …
