Clean electricity options for a free Burma
Chris GreacenPalang ThaiSeminar on
“Energy: Tragedy in Burma”20 November 2007
Chulalongkorn University
Outline
• Default scenarios– For revenue: Mega dams, gas exports– For electrification: power imports & diesel generation
• Addressing the Thai side– Removing bias in load forecasting– Consider clean, decentralized options on level playing
field
• Addressing the Burma side– Some clean community energy options
Tasang7,000 MW
Upper Salween4,000 MW
Lower Salween500 MW
Hut Gyi 1,200 MW
Yawatit600 MW
Tanaosri720 MW
Planned megadams to export electricity to Thailand
Natural gas
• Used to make 71% of Thailand’s electricity (among highest in world)– 1/3 of gas used in Thailand comes
from Burma– 20% of our (Thai) electricity bills pay
for Burmese gas
• Single largest source of revenue to Burmese military government– Accounts for fully half of Burma’s
exports in 2006– US$2.16 billion to junta from
Thailand.– Total, Chevron, PTTEP, Petronas,
Nippon Oil, etc.

Can we imagine something different?
Addressing the Thai side:
1) Remove bias in Thailand’s load forecasting
Demand growth has been linear over the past 20 years…

2007 Forecast Historic peak demand trend
14,500 MW
… so they always overestimate actual demand, building power plants that aren’t needed…
including new hydropower in Burma…

The Arun-3 story
• Planned 201 MW hydro in Nepal• Sell electricity to India, rural electrification• Nepalese NGOs and small business:
“Micro-hydropower cheaper, better for local economy”
• World Bank pulled out of project, project cancelled
• 10 years later…the Nepali power system has seen the addition of:– over a 1/3 more capacity than the Arun-3– at ½ the cost– In ½ the time it would have taken to complete Arun-3
Addressing the Burma side:
(… besides the political and human rights problems…)
1) clean, decentralized energy options – especially for rural
applications
