| + | ==== What use can a hydropower installation satisfy? ==== |
| | | | |
| − | Answer...
| + | *Direct drive of machinery |
| | + | *Electricity production for local use |
| | + | *Electricity feed into grid for revenue<br> |

| | + | ==== How many people can be supplied? ==== |
| | + | |
| | + | *Available <u>share per household (hh) depends on local hydro potential and type of use</u> (lighting, TV, machinery, ...) |
| | + | *Required power for <u>lighting</u> depends on no. and type of lamps used (3 - 5 Watt energy saving lamps are existing)<br> |
| | + | *Machinery needs usually several kW (often machinery's power is given in HP (metrical Horsepower) 10 HP = 7.36 kW)<br>A motors starting power can be 50% higher than its regularly stated power. There are technical possibilities to address these (soft start). |
| | + | *Electrical heating requires very high power. E.g. has a typical water heater ~ 3 kW. Within an isolated grid, electrical heating / cooking / oven is usually not practicable. Hot water can be produced centrally from the ballast load.<br> |
| | + | *Electrical cooling is possible. |
| | + | *Electrical fan ~ 200 Watt. |
| | + | *Radio / DVD ~ 10 W / 2 W |
| | + | *Water pump ~ 1 kW |
| | + | *TV 50 -150 W (depending on type and size) |

| | + | '''What are typical difficulties'''<br> |
| | + | |
| | + | *financial coverage<br> |
| | + | *remote location<br> |
| | + | *specific conditions<br> |
| | + | *uncertain outcome<br> |

| | + | *'''Price range: '''depends on size of potential site, ranges from 2000 - 5000 USD/kW |
| | + | *'''Material needed: '''Turbine, generator, controller come from a specialist |
| | + | *'''Suitable geographic area: '''usual hilly and all year round water flow, also irrigation canals can have good hydropower potential |
| | + | *'''Required competencies: '''Experience in mhp feasibility for pre-study and planning, patience in cooperation with the local entities'''<br>''' |
| | + | *'''How Long does it take: '''Ideally flow measurements should be taken over several years to ensure safe data. A must is the measurement of the minimal flow during dry season. From there on a mhp plant can be installed within one year. Accessibility of remote location, delivery times for turbine and generator and social setup usually take longer than estimated. |
