Case study 9
China’s mini-grids
for rural
electrification
Township Electrification
Programme


Problem
 In

2008, there were still an estimated two
million households, or nine to ten million
people, primarily in villages and farming areas
in western China, lacking electricity, according
to the National Energy Administration


How to solve?


Township Electrification Programme



From 2001 to 2005



100% renewable energy system for village
power





688 villages: PV-battery mini-grids



337 villages: small-scale hydro mini-grids



Expand to 20,000 villages in 11 provinces


Results


Increased electricity access in
western provinces: provide electricity
to 1.3 million people



Electricity for basis services but not
productive uses: improve quality of
life and economic development



Stimulated solar PV production

A PV module in rural
area in China


Lesson learned
A site-specific costbenefit analysis is
required

Tibetan home with 20-watt PV
panel and 500-watt wind turbine


Success factors


Public financing: US$ 293 million from central
government and US$ 437 million from provincial
government



Government-led implementing: National
Development and Reform Commission (NDRC)



Site assessment of energy resources: high solar
insolation, good wind speeds, biomass resource





Preference for local production: System
integrators responsible for design, installation,
operation, maintenance



Focus on capacity building: US$ 100 million
for training and institutional development.


Considerations for replicating


Ability to pay: gauge the ability, willingness and
reliability of customers to make payments to
cover operation costs



Supply and demand balancing: Pricing too low
could lead to excessive demand whereas pricing
too high could lead to non-use.



Operations and maintenance know-how: local
technicians capable or operating and maintaining
the mini-grids to maximize efficiency
