  • Mohave Power Station , a 1,580 MW coal power plant near Laughlin, Nevada , out of service since 2005 due to environmental restrictions [1] The Susquehanna Steam Electric Station , a boiling water reactor . The reactors are located inside the rectangular containment buildings towards the front of the cooling towers .

  • Hydroelectrc is 3% View slide
  • Most of that 3% is from large hydroelectric plants http://en.wikipedia.org/wiki/File:Sayano-Shushenskaya_hydroelectric_station.jpg View slide
  • Classification Size Power Output Typical Use Large >10MW Usually part of a large grid. Small 1MW-10MW Usually grid intertied. (up to 50MW in Canada [1] ) Mini 100kW-1,000kW (1MW) Community and industry. Often grid intertied. Micro 1kW-100kW Small low energy consuming community, small industry, rural high energy consuming household. Usually off-grid. Pico <1kW Radio tower, low energy consuming household, charging station. Almost always off grid.
  • What does that look like? http://en.wikipedia.org/wiki/File:Gluehlampe_01_KMJ.png Size Power Output Large >10MW Small 1MW-10MW Mini 100kW-1,000kW (1MW) Micro 1kW-100kW Pico <1kW

    • Turgo Turbines
  • Micro Hydro
    • Small in scale
    • Minimum environmental impact
    • Site specific : you must have the resource
    • Affordable
    • Consistent: Produces continuously, 24/7

  • Classification of turbine types. Source: Micro-hydro Design Manual, IT Publications, 1993 Types of Systems   High head Medium head Low head Impulse turbines Pelton Turgo Multi-jet Pelton cross-flow multi-jet Pelton Turgo cross-flow Reaction turbines   Francis Pump-as-turbine (PAT) propeller Kaplan
  • Pelton and Turgo Impulse – jet of water 4 “ Don Harris
  • Turbines are turned by water. That turning motion drives a generator which produced electricity. Don Harris
  • The Intake Diverting clean water into the penstock Screen Start of Penstock Steam Flow The intake’s job: Filter and Settle Build it either: Simple and easy to repair Or Bullet-proof Don Harris
  • The Intake Diverting clean water into the penstock Screen Start of Penstock Steam Flow A dirty creek may need more settling time Overflow Don Harris
  • Penstock A full pipe; delivering clean water to the turbine Don Harris
  • Burying Pipe
    • Burying a pipe line removes the biggest eyesore of a hydro scheme.
    • It is vital to ensure a buried penstock is properly and meticulously installed
      • subsequent problems such as leaks are much harder to detect and rectify.
