  1. Micro Hydro Power. A Solution for Thailand.

  2. Micro Hydro Power. OUTLINE Problem & Consequences The Solution Finance Summary Reference

  3. Problem. Large Hydro Power Systems - generate water pressure - propell downstream high speed turbines - cutting the water stream

  4. Problem. Current Small Hydro Power Systems do the same with smaller technology.

  5. Problem. Many Micro Hydro Power Systems do the same with even smaller technology.

  6. Consequences. • - high water flow rate necessary (m/sec) • high hight difference necessary (m) • high turbine rotation (rpm) • water quality depletion (cod/bod/pH) • high water accidity = high corrosion • natural water stream is cut • negative impact on animal population • upstream and downstream effects • often clogged or damaged by debris

  7. Micro Hydro Power. OUTLINE Problem & Consequences The Solution Finance Summary Reference

  8. TheEffect. Gravitational Water Vortex.

  9. The Solution. Gravitational Water Vortex Power.

  10. The Solution. Gravitational Water Vortex Power.

  11. The Solution. Gravitational Water Vortex Power. • - 1.2 m hight difference • 1 m3 / sec. continuous • 12 kW hydraulic capacity • 6.2 kW generator output • 0.9 Capacity Utilization • 50 MWhel / year • free water aeration • fish unharmed

  12. The System. Power Generation Water In Water Out

  13. The Pilot Plant. Schoeftland / Switzerland.

  14. Solution. Gear Box Generator Control Cabinet Rotor

  15. The Pilot Plant. Capacity: 30 kW Grid Export: 263 MWh p.a. Diameter: 6.5 m Water Flow: 0.8 - 2.5m3/s Hight Difference: 1.7m Turbine Frequency: 21 rpm Concrete used: 65 m3 Steel used: 4 t Components: Rotor, Control Cabinet, Gear Box, Generator Features

  16. The Solution. Direct Instream System - 10 - 150 kW - low water flow – only 2-3m/sec - low hight difference – from 0.7m - low turbine rotation – max.60rpm - water quality melioration - low cod/bod, optimum natural pH - fish can pass unharmed up/downstream - debis can pass without damage or clogging

  17. The Solution. New Effect: Gravitational Vortex Certified by SGS 50 kW 90% Availability Water Vortex Power Plant 50 kW 2-3 m/sec 0.7 m Natural COD/BOD/pH Fish Population Unharmed

  18. Micro Hydro Power. FEATURES High Adaption to Local Condition Low Water Input Necessary Low CAPEX & OPEX High Power Output High Capacity Utilization Environmental Impact Positive

  19. Micro Hydro Power. OUTLINE Problem & Consequences The Solution Finance Summary Reference

  20. Finance. CAPEX t.b.developed (>2 M Bht) Cap.Util.< 0.90 OPEX < 1% p.a. IRR> 20 % ROC 3.2 yrs Rev > 400 MWh p.a. / 50 kW inst.

  21. Micro Hydro Power. OUTLINE Problem & Consequences The Solution Finance Summary Reference

  22. Summary. New System - Adapted Technology. Highest Capacity Utilization Lowest CAPEX, O&M. Positive Environmental Impact. Comunity Based and Easy to operate
