Electricity in Thailand:current arrangements, impacts, alternatives 2 August, 2006 ERI Chris Greacen www.palangthai.org
Natural gas • Used to make 71% of Thailand’s electricity (among highest in world) • Cleaner than other fossil fuels (especially SOx) but still big CO2 emissions • Limited domestic supply. • Human rights issues in pipeline from Burma (Yadana) LNG terminal
Natural gas • Severe price volatility – linked to crude oil price. • Now around $0.05 to $0.07 / kWh
Coal • Used to make 14% of Thailand’s electricity • History of respiratory illnesses from coal smoke – Mae Mot, Lampang • Acid rain • Worst fuel for global warming • Limited domestic supply • Cheaper (now) than natural gas ($0.04 to $0.06/kWh) • Strong environmental opposition
Big hydro • Used to make 6% of Thailand’s electricity • Consensus: no more big dams will be built in Thailand • Limited sites left in Thailand • Strong environmental opposition • Environmental issues • Inundation • Fish killed • Global warming • Changes in temperature / sediment loading / flow regime • Can be cheap • If reasonably close to load centers

Khao Laem dam resettlement • According to a study produced by the World Bank's Operations Evaluations Department in 1993, 80% of people evicted by the dam "were...dissatisfied with the resettlement outcome", considering themselves "to be worse off than before resettlement". • "We had to spend all of our compensation for living, and it wasn't enough, actually. The condition of the land here and my previous land is very different...I miss the fertile resources. I could find things for a meal. The thing that I miss most is rice. Rice is my soul. Our ancestors did rice farming for ages. But now I cannot grow rice and have to buy it, which is also very expensive ... If I could ask the officials for one thing, I would like to ask, 'Please can I return to where I was?'" • Panya Kwanprasertwaree, a Karen elder who was forced to move because of the dam
Nuclear • Currently not used to make any of Thailand’s electricity • Cost uncertain • $0.02 to $0.12/kWh • Environment & security issues • Generates materials that can be used to make weapons • Thailand has spotty nuclear safety record already • Waste dangerous for 250,000 years.
What should be done to make sure that there is enough electricity? Industry response… • Natural gas interests say: • “Use more gas!” • “It’s clean(er).” • Coal interests say: • “Use more coal” for fuel diversity • “Clean” coal • “It’s cheaper” • Hydropower interests say: • “New dams in Lao and Burma!” • Asian Development Bank GMS grid • “Big hydro for poverty reduction!” • “It’s cheap” • Nuclear advocates say: • “Nuclear energy is part of the ultimate answer”
What should be done to make sure that there is enough electricity? ADB/World Bank response… ADB’s Indicative Master Plan on Power Interconnect-ion in the GMS
Civil society response… • Fix governance problems • Transparency, accountability, public participation • Remove conflict of interest • Set up empowered, competent regulatory authority • More realistic demand projections • Consider a full range of alternatives in power development plan including: • Energy savings • Renewable energy • Combined Heat and Power
Fix governance problems: Transparency, accountability, public participation
Fix governance problems: Remove conflict of interest • Example: transmission shouldn’t be controlled by the same business that owns generation.
Fix governance problems: regulatory authority • Independent • Able to think for itself • Competent in working for public interest • Public wants reliable, affordable energy without environmental impacts • Empowered • Has authority to enforce the rules

More realistic demand projections • Official Thai Jan 04 forecast overestimated 2006 peak demand by 1674 MW. • Lao NT2 = 995 MW

Combined Heat and Power (CHP)… also called “cogeneration”
CHP potential in Thailand • 8610 MW cogen installed as of 2001 • At least 3,000 MW of additional cogen had applied and have not been accepted.
