Yunnan Huaneng Lancang Hydro Co.
One of five power conglomerates split off
from former Ministry of Electric Power
Officially “stock company” but majority of
stocks are non-tradable
Development begun in 1987; first dam
completed in 1993 (Manwan)

Yunnan Huadian Nu River Hydro Co.
One of five power conglomerates split off
from former Ministry of Electric Power
Officially “stock company” but majority of
stocks are non-tradable
Development halted in March 2004 by
Premier for failure to follow EIA procedures
Ongoing “illegal” development halted again in
spring 2009

Policy Framework
Western Development Campaign (2001)
Send Western Electricity East (西电东送)
Ultra-high-voltage DC lines (800 kV) by 2010
Send Yunnan Electricity Outward (云电外送)
Prioritized in 2001
Send Yunnan Power to Guangdong (滇电粤送)
Focus on resources and infrastructure
Power sales to Vietnam since 2004, Thailand next

China’s dam-builders go south (and elsewhere)
EXPORTING EXPERTISE
Global dam efforts by Chinese firms
Roughly 100 projects (McDonald et al., 2008)
Often coupled with related infrastructure
Investment approach in addition to aid
Roads, bridges, communications
Motivated in large part by primary resource needs
Reforms in electric power industry open door
for flexibility and opportunism (Magee 2006;
McDonald et al., 2008)
Magee, D. Powershed Politics. The China Quarterly 185 (2006).
McDonald, K., et al., Exporting dams: China’s hydropower industry goes global, Journal of Environmental Management (2008).
Exporting knowledge
Africa
Eastern Europe
Albania, Georgia
Central Asia/Middle East
Algeria, Botswana, Ethiopia, Congo, Sudan
Kazakhstan, Kyrgyzstan, Uzbekistan, Iran, Pakistan
And of course, next door…
China and Mainland SE Asia
China upstream, regional power
Mekong River Commission (MRC)
Projects key to China’s western and regional development
Concerns downstream about China hegemony
Cambodia, Laos, Thailand, Vietnam members
China, Myanmar dialogue partners
MSEA governments, with or without blessing of MRC,
buying into China hydro development
Inter-government Agreement for Power Trade in GMS
Thai co-investment in Chinese power stations
Power sales from China to Vietnam
GMS focus on regional power grid integration
Power lines across Laos to Thailand
Mekong River Commission
New Strategic Plan (2006-2010)
“more investments in irrigation, navigation, and
hydropower are bound to occur”
“appropriate exploitation of hydropower potential”
“potential area for cooperative development”
Review & update hydropower assessment (30 GW)
Hydropower “can play several important roles”
Modeling & assessment of proposed projects
13 GW on mainstream Mekong
13 GW on major Mekong tributaries
Energy Profile: Cambodia
Installed capacity:
~0.012 GW
Theoretical capacity:
~10 GW
Much of infrastructure, including power grid,
was destroyed during latter half of 1900s
Widespread dependence on diesel
generators for power (high cost, highly
polluting, dependent on oil imports)
More than 20 isolated systems
Energy Profile: Vietnam
Installed capacity:
~4.5 GW
Theoretical capacity:
~18 GW
Plans for additional 5 GW by 2010
Transboundary power sales already
occurring from Yunnan since 2004 (110 kV)
New 500-kV line completed in 2006
Energy Profile: Laos
Installed capacity:
~0.7 GW
Theoretical capacity:
~30 GW
Second greatest hydro potential on Mekong
“Battery” for powering GMS development
“Transhipment” point for power transfers
Sinohydro, China National Electronics, and
China Datang all bidding on Mekong cascade
e.g., Xanakham (600 MW, US $880M)
Energy Profile: Thailand
Installed capacity:
~3.5 GW
Theoretical capacity:
~15 GW
Most of technically, economically and
politically feasible hydropower already built
Significant popular resistance to new projects
and to operating rules of existing projects
Energy Profile: Myanmar (Burma)
Installed capacity:
~0.75 GW
Theoretical capacity:
~37 GW
Developing massive reserves requires
international partnerships, made difficult by
military regime in power
Ta Sang Project on Salween: 7110 MW
Thailand major investor, Chinese interest growing
Majority of power will go to Thailand
Sinohydro
Consulting and construction company built
from assets of former MEP
Projects
Kamchay 193 MW, US $280M, largest investment
by China in Cambodia, largest hydro project in
Cambodia; also Kirirom III (13 MW)
Paklay (1320 MW) on Mekong in Laos
Also high-speed rail in China and other
infrastructure projects in Angola
Grid Corporations
Two national-level grid corporations from MEP
Restructuring in 2002 was intended to
separate generation from transmission in the
electric power industry
China State Grid Xin Yuan International Investment
Co. for Kirirom III (13 MW) in Cambodia
China Southern Power Grid signed MOU in 2007 to
conduct feasibility study for Sambor (3300 MW or
465 MW) and Stung Cheay Areng (260 MW) in
Cambodia
SOUTHEAST ASIA’S RIVERS
BE DAMMED?
Why the push southward?
China’s power shortages, future surplus?
“Soft power” approach to regional relations
Resource diplomacy throughout GMS
Curbing Japanese influence in the region
Japan Banking and Investment Corporation wields
considerable influence through infrastructure funds
Asian Development Bank – Japan major partner
Mekong River Commission – Japan major donor
Social and Ecological Concerns
Changes to flow regime may impact downstream
fishing and agriculture
Sediment trapping reduces natural fertilization of
floodplain and dam efficiency
Resettlement disrupts social fabric and livelihoods
Interference with local power provision
Concerns about increase in dissolved gases,
potential for methane production in warm reservoirs
Great uncertainty due to political obstacles to
scientific collaboration and data-sharing
Monsoons
Real concerns about
dam impacts on
unique Tonle Sap
ecosystem
Monsoon season
Dry season
Water enters lake
Water leaves lake
Major protein and rice
source
Monster Catfish
Charismatic megafauna?
Giant catfish of symbol of
unique Mekong system
Decidedly less cuddly than
pandas
Real concerns about
future of anadromous fish
in Mekong and tributaries
~10 species migrate north
past Chinese border
No fish passage structures
Pros and cons of large dams
Benefits
Irrigation
Flood control
Power generation
Navigation
Recreation
Costs
Altered flow regime
Impacts on ecosystems and
human communities
Change in water quality
Population displacement
Habitat alteration
Health risks
To dam or not?
Multipurpose dams
How do dams alter the hydrograph of a river?
Why do they often fail to meet design expectations?
Highs? Lows?
Particularities of dams on transboundary rivers
in China/Mainland SE Asia
Do the benefits outweigh the costs?
Is C/B analysis even a good way to evaluate?
Sustainable Development?
