The hydroEngine is a proprietary hydropower turbine designed for high flows at low heads generating electricity at or less than US$0.05 at projects as small as 1 MW. Civil works and installation are also simplified delivering significant cost savings.
The hydroEngine has two basic configurations:
A Fully Flooded model rated 200-500 kW per unit that works with a draft tube and accommodates sites with more tailwater variation.
A Free Jet model rated 25-1,400 kW per unit that does not need a draft tube.
- Works best with lower heads and large flows
- Competitive cost savings for both the turbine (less expensive manufacturing) and civil works (reduced excavation)
- Units rated up to 6 m net head
- Accommodates larger tailwater variation
- Works best with higher heads, and/or where draft tubes are a challenge due to civil works constraints
- Open flow, cylindrical runners, vertical discharge, and no draft tube
- Units rated up to 20 m net head
The hydroEngine is uniquely suited for low-cost development of small hydropower resources due to low-cost civil works and flexible installation constraints. hydroEngine plants can follow several different layouts - run of river, over canal or in dam - depending on the best fit for each site.
Run of river
In dam or weir
The hydroEngine can be installed into existing infrastructure, using the existing waterway as a bypass, or alongside the existing works in a standard, minimal excavation, plant layout.

Your Site Estimate
Plant Design Head is an estimate of the pressure at the turbine inlet, caused by the change in height between headwater and tailwater.
Plant Design Flow is an estimate of the maximum flow for which your hydropower plant is designed. It may be less than the maximum flow of your canal, stream, or river, and is generally a balance between power output, cost and environmental considerations such as minimum in-stream flow requirements.
Capacity Factor is an estimate of the ratio of the plant's actual output over a period of time (usually a year), to its potential output if it were possible for it to operate at full nameplate capacity continuously over the same period of time. Typical capacity factors for hydro power are between 40 and 60%. Reference: US EIA
Generation is an estimate only based on rough input parameters. Actual site results will vary.
