Electrification Program in China

Background
- China
is a developing country with about 70% rural population;
- Rural infrastructure
is poor, it needs be improved with a great efforts;
- In recent
years, more than RMB 280 billion (EURO 28 billion) have been invested
for rural grid improvement including extensions.
- However,
by the end of 2003, there are still about 29,000 villages with about
7 million rural households (about 3.55% of the total population) which
are not connected to the grid.
Renewable Energy Resources
- Hydropower:
about 395 GW,
- Solar energy:
about 2400 Bio. Tce /year,
- Wind power:
about 1000 GW,
- Biomass:
about 840 Mio. Tce /year
Efforts from 1970--2000
- small hydropower:
28 GW,
- small wind
turbines: about 160,000 sets with a total capacity of 25 MW,
- Solar home
systems: about 30,000 sets with a total capacity of 600 kWp have been
disseminated,
- The installation
was realized through many provincial projects with certain support from
the state government.
Brightness Program
- The “Brightness
Program of China ” was drawn up under the leadership of former State
Development Planning Commission during 1996 till 1999
- The plan is to
speed up the activity of decentralized electrification of remote rural
areas; it is also a positive response to the proposal of the world solar
summit in Zimbabwe.
- It is planned
that 23 million people in remote area shall be electrified by wind and
PV technologies till 2010 with an average capacity of 100 W per capita.
The total installed capacity will reach 2,300 MW then.
Pilot
Projects of the Brightness Program
Pilot
Projects
- Under the
leadership of SDPC, the pilot projects were lunched in March 2000.
- Applied by
provinces, Inner Mongolia, Gansu and Tibet were selected as pilot provinces
- SDPC allocated
RMB 20 million grant for the projects and installed a executing system
- About 5500
sets of Wind/PV hybrid home systems, 1 W/D/B village system were installed
in Inner Mongolia by end of 2003
- About 10,000
solar home systems and 3 PV mini-grid village systems were installed
in Gansu by end of 2002
- 6 PV village
systems around 6 kW were installed in Tibet by end of 2001
Installations of the Pilot
Projects
Supported by SDPC, MOST an SP,
electrification project of Ali Prefecture, Tibet was implemented in
2001. 688 kW PV were installed. The total investment is about RMB 70
million.
- 11,000
sets of 40W PV home systems
- 30 sets of
5 kW PV village station
- 30 sets of
PVP systems
- 10 sets of
400W PV TV antenna receiver
Program in Ali Prefecture
of Tibet

Program (1)
- It is the
first step towards the large-scale dissemination of renewable energy
technologies for decentralized rural electrification launched in 2002
by NDRC.
- The objective
of the program is to supply power for the basic needs of the 1,065 not-connected
township locations, which are distributed in 12 provinces, by
use of small hydropower, PV and PV/wind hybrid systems under consideration
of the actual resource-situation of the location.

(2)
- 688 PV or
PV/wind hybrid mini-grid systems with a total capacity of 20 MW will
be installed by the end of 2004, most of them have been in operation;
- 377 small
hydropower mini-grid systems with a total capacity 264 MW will be installed
by the end of 2005;
- The total
investment was RMB 4.7 billion;
- All of the
townships of China are supplied then;
- More than
1 million people benefits from the program

Experiences
- It is feasible
to electrify remote areas by RE technologies as the least cost option
compared with grid extension and diesel generation.
- Government
grant and support are necessary as the costs of RE technologies are
still relatively high at present and difficult to be financed by the
rural population
- The RE electrification
significantly improves living conditions of the local people and provides
better opportunity for the social and economical development, although
the RE power may only satisfy a limited range of needs such as
lighting, communication, and small-scale machinery and equipment.
- Capacity
building, training and set-up of local service networks are fundamental
conditions to guarantee a long term success and sustainable development
of the program.
Challenges
- The operating
costs of some RE technologies such as PV are still very high on this
stage due to the limited lifetime of the batteries, a long term subsidy
is actually needed even under the condition of the capital investment
being granted. An appropriate cross subsidy scheme with grid power has
therefore to be established;
- How to install
a commercial approach of a long term O&M system based on necessary
subsidy condition?
- How to optimize
the function of the RE systems with their limited capacities to deal
with increasing requirements of the mini-grid users to achieve good
benefits?
- How to extend
the lifetime of the battery bank to limit the running costs of PV systems?
Outlook
- “Renewable
Energy Promotion Law” is already in the pipeline of the legislation
system to establish the legal framework for the further development
of renewable energies
- RE technologies
will continue to play an important role for the electrification of the
remaining 7 Mio. households in remote areas till 2010
- It is planned
to install about 1 GWp PV during the 11th Five-year Plan
(2006-2010)
- Large scale
dissemination is expected.
Significances
- We hope that
our experiences are useful for other developing countries to provide
electricity to their un-electrified rural population who counts in total
for more than 2 billion in the world;
- Our efforts
will contribute to the renewable energy development, limitation of emission
and sustainable development of human society;
- China offers
a huge market for RE industry of the world.
It is really good to have
a electrical light !
Thanks!
We would
express our sincere appreciation to those nations and international
organizations that supported us in the field. China welcomes all of
you to join us in the next large scale programs!
