Serialization

  • Small hydro turbines have a total
  • f 26 models in series, 83 kinds of

products, applicable in the head range of 2 ~ 1000 meters.

  • Auxiliaries

including governor, exciter, valve, control panel and automatic components etc. all being produced in China.

Import 10 factories serialization  Completely done in manufacturer , trucked to the site  Less Time and Cost on site

  • 90% of the rural

households have access to electricity.

  • On average, per

capita electricity consumption is around 200 kWh.

Favorable policies for SHP-RE

  • “the one who invests owns and operates”
  • “revenue from electricity for development of

electricity”;

  • a preferential rate of value added tax rate of 6%

instead of the normal 17%;

  • the connection of small local grids to larger grids.
  • Policies designed to protect electricity supply areas

for small hydropower

CONCLUSIONS

  • Put it under the time axis
  • Put it under the rural electrification
  • Put it under the rural development
  • It is small hydropower in China.
