The Scott Hydro Turbine is rated at 1500 watts output. For comparison, a home using non-electric heat in the USA consumes on average about 1000 watts continuously, well within the potential of a single Scott Turbine. Unlike most water turbines which have axial or radial flows, in a cross-flow turbine, water passes through the turbine transversely or across the turbine blades. After passing the runner, it leaves on the opposite side. When the water leaves the runner, it helps clean the runner of small debris.
You also have the option of choosing an electrical kit to go with your turbine. Each kit includes everything you need to wire the turbine into your electrical system, whether you want to use it in a grid-tie AC power system, or an off-grid 12V or 24V battery system. Scroll down to see what items are included in each electrical kit.
The Advantages of a Scott Hydro Turbine:
- Designed & Manufactured for years of maintenance free service
- System runs 24/7—365 days a year in all weather conditions
- Turbine housing constructed of heat treated aluminum with powder coated finish
- Entire assembly made out of non-corrosive material
- Bearings are double sealed permanently lubed stainless steel
- The runner, shaft and fasteners are made from 300 series stainless steel
- Permanent magnet alternator: 3-phase AC direct drive with no gear box
- High voltage AC output for long line transmission capability
- 3-phase rectifier changes AC to DC for battery charging
- Generator is rated at 1500 watts output, and capable of up to 2000 watts depending on installation conditions
- Ideal for low head conditions as low as 15 feet of vertical drop (9 psi minimum water pressure)
- The flat efficiency curve yields better annual performance than other turbine systems
- Excellent behavior with partial load or low stream flow
- Well suited for unattended electricity production
- There are only three rotating components = Simple maintenance
- Almost no turbine noise
- Self cleaning. No runner cleaning is necessary
- No dam required-simple diversion up stream or any water source meeting requirements
- Made in the United States of America

Question:
I have a large pond/small lake with a dam at the outlet. It is a spring fed lake with continual flow over the dam year round. The only issue is I will only be able to gain about 12feet of head. The volume of water flow is plenty and constant. Can I still utilize this product to create 120v AC to power a year round cottage?

Scott HydroElectric's own website cites a minimum of 15 feet of head (with 25ft minimum recommended), but also suggests an alternate minimum measure of 9 psi water pressure at the turbine inlet. However, their calculation for converting feet of head to PSI says 15ft only results in 6.51 psi, so their own recommendations are mixed.
Here is a link to download the manufacturer's site evaluation instructions. You may be able to determine whether or not your site will work by following this pdf: Hydro Turbine Site Evaluation Guide. In the meantime, I will also contact them and see if I can gain some clarity on their recommendations.

Tim,
I heard back from Scott Hydro, and they don't recommend using their turbine with only 12 feet of head.
