1 Mini & Micro Hydro Power Generation EBARA Hatakeyama Memorial Fund Tokyo, Japan
2 Definitions Large Scale hydro power generation : Capacity 100(MW) Most of them involve major construction of dams. Small Scale hydro power generation : Capacity 5(MW) per site Commonly do not involve major construction of dams. Most of them are Run-of-river type. less environment impact Micro Scale Hydro : Capacity 100(kW) per site
3 Advantages of Mini/Micro Hydro Schemes 1. Renewable and sustainable source of electricity Hydro energy is a free and a continuously renewable electrical energy source. Hydropower is a completely national resources, without importing any other fuel. 2. Little or no environmental impact No water pollution or greenhouse gas emissions 3. Technology is proven and reliable 60~80(%) efficiency for conversion to electricity Low operating and maintenance costs Full time staff are not required for serving. The system can be integrated with water supply for irrigation and potable systems The working life of the machine is much longer than for diesel generator
4 Advantages of Mini/Micro Hydro Schemes (continued) 4. Long life equipment Existing plants have been in operation for more than half a century and are still providing continuous power as long as water resources are sufficient. 5. Create job opportunities locally In remote areas, small hydro may have a positive impact on the development of local communities where young people may leave the farms because of low income from farming. The possibility of supplementary income from local electricity production with possibility to start small industry could be the goal for small hydro development in remote areas of developed countries as well as for developing countries. Hence, reduce population migration from remote rural area to urban
5 Disadvantages of Mini/Micro Hydro Plants 1. Seasonal Water Flow Fluctuation Flows often vary throughout the year, affecting the availability of water in a certain seasons. 2. Location is everything Locations where power can be economically exploited are limited. The best sites have a reliable water supply year-round and a large vertical drop in a short distance. 3. Long construction period and higher initial investment The problem is that the new investors place primary importance on short payback time( Fast Money ), where the long life of system is not reflected in the economic analysis of small hydro projects.

9 Intake Canal Route Parallel to river system A system taking water from the up-stream, providing a canal along the river and feeding water to turbine by steep penstock Short cut system A system providing a short cut canal at the bend of a river, and feeding water by steep penstock.

16 Water Intake Facility for Micro Hydro Turbine
17 Points necessary for Mini Hydro Exploitation The following items shall be taken into the consideration for Mini Hydro Exploitation. A high rainfall catching area A river or water source with a suitable head of water A easiness of water intake placing in a stream A easiness of transporting the water to the turbine (Easiness of installation of conduit pipe or channel) A easiness of electrical distribution line/grid connection A easiness of returning its water to the main stream Topography, Rainfall data, Availability of funds
18 Assessing Hydro Plant Capacity The amount of energy at a given site can be assessed as ; P=9.8 Q H e, e=ηt ηg ηgr where, P : Plant capacity (kw) H : Turbine net head (m) Q : Water flow to turbine (m 3 /s) e : Turbine generator combined efficiency Mini Hydro : approx. 75~85% Micro Hydro : approx. 65~75% ηt : Turbine efficiency(=75~90%) ηg : Generator efficiency(=85~96%) ηgr : Speed increaser efficiency(=97~97.5%) For assessing the power potential, Q and H shall be measured at site.

24 Comparison of Turbine Performances
25 Flow Duration Curve Flow Hydrograph : A period of 20~25 years records is required for planning the Run-of River type Plant. The most suitable design flow for run-of-river type power station is around 95 day flow. 95day The area below the curve shows the energy of hydro potential in the river Flow Duration Curve : A curve of flow versus the percentage of time. This curve is usually the most convenient form for turbine size selection.
26 An Example of Flow Duration Curves Flow (m 3 /s) Days
27 Design Flow for Conventional Turbine too small design flow (Run-of of-river type Mini Hydro Plant) too large design flow 365days operation available operating duration shorter Bypass flow from turbine increased (cannot operate in dry season) Bypass flow decreased Annual Energy Output(kWh) = 365(days) x 24(hrs) x Pg(kW) Unit Electricity Cost( /kwh) = Total Construction Cost Annual Energy Output
28 Flow Duration Curve vs Unit Efficiency ηmax In case of maximum efficiency (ηmax) being selected on extreme partial flow point, the runner cavitation at maximum flow shall be carefully studied.
29 The cost of the Mini Hydro Plant is site specific and may vary widely from scheme to scheme The cost of the Mini Hydro Plant is site specific and varies greatly depending on the remoteness of the site and physical features of its major components, namely, civil works (including waterways), generating equipment(turbine, generator, control, protection) and electrical transmission/distribution lines. While the cost of generating equipment in the powerhouse is almost a linear function of kw/h 0.5, the cost of civil works further depend upon the gradient of the waterway(intake to powerhouse). Similarly, the cost of electrical line further depends upon the energy density of the load centers. Therefore, the coat of Mini Hydro Plant installations can vary widely from scheme to scheme. The share of initial civil works component cost may vary from a mere 20% for a relatively high gradient waterway profile and low cost construction to 60% for a relatively low gradient and expensive construction. Therefore, the percentage share of one component on the total initial investment cost would depend upon its own as well as other component s construction feature.
