11. Strategic Significance of Hydropower in China
• To adapt to climate change
• To safeguard energy safety
• To reduce poverty
• To support social, economic development

12. To Adapt to Climate Change
China’s Energy Structure
Hydro 7%
Nuclear & others 2% Non-fossil 9%
Fossil 91%
Copenhagen Commitment: by 2020,
•Non-fossil energy: up to 15% Coal 76%
Oil 11%
•Carbon emission: down 40-45% Natural gas 4%
than 2005 Fossil
Non-fossil

13. To Safeguard Energy Safety
China’s Power Structure
• Proportion of thermal Wind Nuclear
2% 1%
power: too large (74%)
• Increase hydropower: Hydro
inevitable choice to adjust 23%
power structure Thermal
74%

14. To Reduce Poverty
• China’s hydropower
resources concentrate in
western less-developed
regions
• Hydropower: boost
economy, reduce poverty

15. To Support Social, Economic Development
Industrialization Development Stage of Hollis B. Chenery
Per-capita GDP ($) Economic Development Stage
300-600 Primary Products Stage
600-1200 Initial Stage
1200-2400 Middle Stage Industrialization Stage
2400-4500 Advanced Stage
4500-7200 Early Stage
Developed Economic Stage
7200-10800 Higher Stage
• China GDP per capita: $ 4,371
• Population under poverty line: 150m (< $1.2/d/p)
China needs hydropower to support social and
economic development

16. Strategy of Hydropower Development
• To actively develop hydropower on the premise
of ecological protection
• Goals:
– Total hydropower: 380 GW by 2020
– Including conventional hydropower: > 330 GW

21. Challenges of Sustainability; Solutions
 Dam safety
Mostly built in 1950s- 70s Reservoirs repaired &
reinforced (in 10 yrs: 7,356)
Danger removal and
reinforcement Reservoirs to be
repaired & reinforced
Safety monitoring (in next 5 yrs: 41,000)
Emergency response Research, management,
monitoring (guarantee
Informatization and system, emergency
modernization response, warning…)

22. Challenges of Sustainability; Solutions
 Laws and regulations
Property of hydroenergy Central government’s
resources No. 1 Document in 2011
Benefit sharing One of 4 goals:
to establish institutions and
Whole-process monitoring systems for scientific
& management development of water
resources
……

23. Challenges of Sustainability; Solutions
 Hydropower price
Lower than thermal Market-oriented pricing
