SHP In China
China has 17% of the earth's hydropower resource
and has installed around half of the world’s SHP capacity.
Since the establishment of the Peoples’ Republic in 1949,
approximately 20GW of SHP has been constructed, with more
than 80% of this coming on-line since the mid 1970s. One third
(7GW) of this total capacity is below 500kW and 14.5GW is
below 10MW. The economic SHP resource is estimated to exceed
70GW. The latest statistics about China’s SHP can be found
in the annex of this article. Table 1 shows the provinces
with total capacity of small hydro power over 1,000 MW.

Capacity under 50MW was classified as SHP
As many as 56 million rural Chinese people still do not have
access to electricity, but the wide dispersal of the unelectrified
communities tends to make large-scale centralized generators
and extension of electric grid networks impractical or uneconomic.
These problems have to be addressed by exploiting locally-available
energy forms to stimulate rural self-reliance. SHP is a key
environmentally-sound solution for improving the economic
growth rate in Chinas vast rural areas, many of which have
rich, undeveloped SHP resources.
The Government has major plans for continued rural electrification
via SHP; the technology is now well-proven and is cost-effective
in areas remote from the grid. As such the investment risk
for new SHP projects is low. China is perhaps unique in promoting
a national policy which places equal importance on hydro and
thermal power, and which devotes as much attention to small
hydropower as to medium and large scale projects.
In recent years the rate of commissioning of new small hydro
capacity has been around 1000MW per year. The Chinese government
plans to install between 1500 and 2000 MW of SHP capacity
every year between 2001 and 2005, in conjunction with improving
water supplies for around 20 million people.
The Electric Power Law of 1996 established the framework for
foreign investment in Chinese power projects. “The State will
encourage and introduce domestic and foreign financial sources
to invest in exploiting electricity sources and erecting enterprises
in this field”. Article 3 of Chapter 1, stipulates that investments
in the electric power industry observes the principle of “He
who invests is he who profits” and “ the investors are empowered
with legal right over the electricity generated from their
investment.” In the respect of medium and small hydro power,
“The State advocates the development of medium and small hydro
power which could improve electrification in the rural areas.”
China's practice and experience has shown that exploitation
of medium and small hydro power can give impetus to rural
economic and social development. As this experience now has
been upgraded to law, it should have a profound effect on
the future development of medium and small hydro power in
China. In many respects, the key features of China’s approach
to SHP development during the past thirty or so years could
be a blueprint for SHP and rural electrification in other
developing countries. SHP implementation is very much decentralized
away from central government, with local government and local
communities taking on responsibility for construction and
management of their plant, and ultimately consuming the electricity
produced. This is achieved by mobilizing capital from a number
of channels, including all levels of government, the local
community (mainly farmers), share-holders and private enterprise,
and development banks. Nevertheless, the State Government
has certainly assisted new SHP capacity building by identifying
the value of the resource as a tool for rural electrification
and development – as stipulated in various state directives
– and backing this with partial financial contributions.
