In the post we will talk about small water turbine price, 1kw hydro turbine price, ultra small water power generator and how to make a water turbine generator at home. keep reading.
small water turbine price
It’s quite difficult to make generalisations about the cost to build hydro systems because of the different combinations of head (the change in water levels between the intake and discharge) and maximum flow rate, and how that affects the maximum power output and choice of turbine type.
Also the extent of any civil engineering works is very site dependent, with some new-build sites requiring everything to be built from scratch, while other retrofit projects can make use of and adapt the existing civil engineering structures.
Having said that, we’ll try to answer the question anyway to give you an idea of the ‘scale’ of costs involved. The table below is a rough ball-park estimate of typical project costs for systems requiring an ‘average’ amount of civil engineering works and grid connection upgrades and assuming access to the site was reasonable. In all cases it is assumed that good quality hardware is used throughout, which we would recommend anyway if you want a reliable hydro system in the long-term.
It is possible to install systems for a lower cost, particularly if the existing infrastructure at the site lends itself to easy adaption for a modern hydropower system so only modest or no civil engineering works would be needed. However even in the most favourable circumstances it is unlikely that the cost would reduce by more than 50% from that shown in the table.
|Maximum Power Output||Estimated Project Cost||£ / kW installed|
To estimate the cost to build hydro systems for a maximum power output between the bands shown, use the chart below and read-off the appropriate £/kW figure – for example a 130 kW hydro system would be approximately
130kW x 4,800 £/kW = £624,000.

Hydropower system build cost
You’ll notice that very small hydropower systems are disproportionately expensive, and this is because hydro projects of any size have to include a substantial fixed-cost element at the design and consenting stages, and to a slightly lesser degree during the installation stage. This is why we generally advise people that to get an economically-viable hydropower system the maximum power output will have to be at least 25 kW, and preferably at least 50 kW. Smaller systems can make sense, particularly at sites with higher heads or if other intangible benefits, such as sustainability, environmental protection or publicity, are valued as much as return on investment.
The payback period for the project can be reduced keeping the inlet screen clear of debris which maximises energy generation.
Hydropower generation benefits consumers through lower electricity costs. States that get the majority of their electricity from hydropower like Idaho, Washington, and Oregon on average have energy bills that are lower than the rest of the country. Relying only on the power of moving water, hydro prices don’t depend on unpredictable changes in fuel costs.
Hydropower offers the lowest levelized cost of electricity across all major fossil fuel and renewable energy sources, and costs even less than energy efficiency options, according to a recent study from Navigant Consulting and the American Council on Renewable Energy (ACORE).

The levelized costs show above reflects the relatively low cost of hydro in terms of maintenance, operations and fuel costs when compared with other electricity sources and across a full project lifetime. For hydro projects, a longer lifespan (in the Navigant study, assumed at 50 years) means not only are costs spread across a longer timeframe but also takes into account that the power generating equipment used at these facilities can often operate for long periods of time without needing major replacements or repairs.
These low balance-of-system costs only make it more critical that we expand the country’s hydropower capacity, but like any other major power generating source, significant up-front costs remain, and the right mix of tax and other policy incentives will foster growth of this reliable, cost-effective and clean resource. In addition, the new technologies that hold tremendous promise – such as marine and hydrokinetics – need continued R&D funding in order to reach their full potential. Learn more about the policies that support hydro development.
A look at the installed project costs – as opposed to levelized electricity costs – for various types and sizes of hydro projects reveals a wide range, and a number of technologies need continued or expanded federal incentives, supportive tax and regulatory environments and other support to improve and deploy at the project level.
|Hydropower Technology||MW Range||Installed Cost ($/kW)||Discussion|
|Conventional Hydro (impoundment)||50 (average)||$1,000-$5,000||A mature technology, conventional hydro falls at the lower end of the range of installed costs, particularly for upgrade projects at existing sites. New dams and greenfield sites are more expensive.|
|Microhydro||< 0.1||$4,000-$6,000||The installed cost for low-impact hydro systems is not expected to decline in the near term.|
|Run of River (diversion.||Approx. 10||$1,500- $6,000||Similar to conventional hydro, installed costs for run-of-river can vary widely.|
|Pumped Storage||>500||$1,010-$4,500||Traditional pumped storage is a proven technology and costs are not expected to decline going forward. The new underground pumped storage technology has been quoted at $2,000/kW and cost declines can be expected going forward, if the concept proves itself.|

New types of hydro that have yet to be widely deployed also carry different costs.
|Marine Technology||Expected Commercial Cost||Discussion|
|Wave||Installed Cost (in 2020) is expected to be approximately $2,500/kW||Wave technology is still under development and needs R&D support to realize the promise of ocean power.|
