China’s SHP Development
By the end of 2004, total installed capacity 34661mw, evaluated to two Three gorges project. SHP:LHP=2:3
In 2004, 3470 MW SHP was added from 2904 SHP Stations, total investment in SHP 37.7 billion yuan.
311 counties generated electricity from SHP of more than 100GWh in 2004.
0.66 million people were employed by SHP enterprises
China’s SHP Development
98% of renewable energy in China is from SHP at present
55% of power generation capacity owned by county level or below in whole China is from SHP
SHP is the indispensable electricity source in remote and/or poor areas where large grid can not reach
About one half of China’s territory, one-third of counties and one-fourth of population mainly relies on SHP
SHP Based Rural Electrification Program
2001—2005, 400 counties to be electrified mainly by SHP, covering 1.99 million km2 of 24 provinces , serving 40.87 million families, 152 million people Build 8,000 MW and associated power grid, Total investment 70 billion RMB Yuan
Send Electricity to Villages Up to the end of 2004, China still has 10 mil. people without electricity. They mainly live in remote areas.
Small hydro power is the most effective electricity supply solution for villages without electricity. Conventional method is inadequate for solving the problem. Project: 100~500 kW for a single township, 500~2,000 kW for several Total investment: 5.8 bil. Yuan (US% 701.3 mil), directly from central government
Replacing Fuel Woods with Electricity Plan: 2003—2020 provide electricity for 28.3 mil families, 104 M people, for cooking and heating Annual new installation 24.04 GW electricity 78.1 TWH Total investment: 127.3 bil. Yuan ( 50% from Government) Pilot Phase: 27 SHPs in 26 counties of 5 provinces Newly added installation 58 MW, investment 280 mil. Yuan Serving 300,000 people, electricity price 0.19~0.30 Yuan/kWh, 40% of normal price
Upgrade Local Grid in Rural Areas In SHP supply areas, Investment for power grid in rural area of 240 counties (1998-2003): 21.3 billion Yuan Investment for power grid in 208 county-towns (2003) 5.9 billion Yuan Price reduction: 15-30 cents/kWh Total investment for whole China from 1998 is about 500 bil. Yuan

Small is a hot spot for private investment Case 1: Jingning County, Zhejiang Province Total population: 170,000, among them 50,000 have shares in SHP projects. Most of them are villagers Case 2: Longmen SHP Project, Tonglu County, Zhejiang Province • Head:340 m, flow:1.123m3/s,
capacity: 3200 kW,annual generation: 1.2 GWh, reservoir capacity: 1.2 mil. M3 • Private-owned, payback time 7
