PowerSpout TRG (Turgo) Micro-Hydro Turbine

Call for Price

  • Turgo/Impulse style micro-hydro turbine
  • Designed for high-head, low-to-moderate flow sites
  • Water flows downhill via a penstock (pipe) to build head pressure
  • Call to see if a Turgo-style turbine is right for your site!


PowerSpout’s Turgo water turbines bridge the gap between very low-head install locations, and very high-head low-flow locations. If your location has at least 7 feet of head, and 8+ liters/sec of water flow, a PowerSpout TRG might be ideal for your power system. And if you have a site that can generate more power than one turbine, you can install multiple turbines up to the limit of your water flow. Each turbine can generate up to 1.6kW of power, depending on your water flow.

  • Head range: 2 to 30 (6.6 –100 feet)
  • Maximum flow/turbine: 16 l/s (254 gpm)
  • Minimum flow/turbine: 8 l/s (127 gpm)
  • Dimensions: 430 x 410 x 350 mm (16.9 x 16.1 x 13.8 inches)
  • Maximum power: 1200W (Standard) or 1600W (HP)
  • Maximum current rating: 32 amp

The TRG can work off-grid, on-grid or directly connected to a resistive element. A standard turbine is capable of up to 1200 watts, the high power turbine is capable of up to 1600 watts (special cases up to 2000 watts). Thousands of PowerSpout turbines are running around the world and they have been proven to be very reliable and cost effective.

The PowerSpout TRG is situated at the end of a long pipe that creates the fall. The head of pressure is this fall. At the turbine there are jets which convert the pressure (head energy) to a high velocity jet (kinetic energy). This high velocity jet impacts on a specially shaped Turgo rotor that extracts almost all the energy from the high velocity flow. This Turgo rotor is directly connected to a permanent magnet alternator which produces electricity. The current is rectified within the unit to DC suitable for a Maximum Power Point Tracking (MPPT) battery charge controller or a grid-tied inverter (GTI).
