electrification. As of 2002, the SHP
installed capacity is equal to 33.7% of
the installed capacity of large
hydropower. Overall, estimates are that
about 300 million people in 400 counties rely solely on SHP while up to
another 400 million rely in part on SHP.
During the first development
phase of rural electrification in China,
despite policies concerning poverty
alleviation and agricultural development, electricity supply in rural areas
is not the priority for the central
government. The central government
paid special attention to commercial energy construction,
such as large power stations, coal mines, and oil fields, to
provide energy for cities and industries. One thing stood

China is characterized by distributed
self-production from local resources
rather than large-scale energy companies. These DPCs are administered
by the government at the local township, county, or village level. They not
only own distribution business but
also run subtransmission (35 kV)
systems and generation plants. The
DPC, especially SHP, has been regarded as the most successful rural electrification experience. It is also part of
the bottom-up approach.
Most SHP plants are located in southwestern and central
China, where water resources are abundant (see "SHP in
China"). They are developed particularly for supplying rural
