IGES-URC Regional Workshop in Asia

on Capacity Development for the Clean Development Mechanism

Organized by: Asian Institute of TechnologyUNEP RISØ Center, Denmark Institute for Global Environment Strategies, Japan

29th September – 01st October, 2004,AIT Conférence Centre, AIT, Bangkok, Thailand

• Project to build, own & operate a 22MW gross rice

husk fueled power plant in Pichit province

• ATB is developing identical projects in 3 other

provinces

• Fuel supply from some 30 rice mills for Pichit

alone; ATB has contracts with some 100 mills

• Electricity supplied to EGAT’s grid through 25-year

Firm PPAs

• Rice husk ash sales to local cement manufacturers

• Emissions reductions generate additional revenue

introduction to the ATB project

multiple projects in Central Thailand

rice husk supply

• Rice farmers in

Central Plains

plant and harvest

3 times per year

• Stable annual rice

production

• Ample supply of

rice husk

rice husk supply• About 30 supplying

rice mills in 3 provinces for each

plant

• Long term supply

contract is best...

• ...but good relationships

are key

a cleaner alternative

This mill’s rice husk boiler, stoked by hand is inefficient and produces unfiltered emissions.

a cleaner alternative

Open burning

releases methane

(CH4), creates

caked ash and

releases heavy

smoke

renewable energy in Thailand

• Biomass fuels < 1 % of firm capacity

• ATB Pichit’s 22MW rice husk power

= 89,000 tons of bituminous coal per year

= 59 million litres of fuel oil per year

= 80-90,000 tCO2e per project, per year

technology highlights -> combustion

• Suspension-fired boilers: rice husk burns “in-suspension”

technology -> plant flow

technology -> plant flow

• Good quality ash eliminates environmental issue of ash disposal

• First example of state-of-the-art technology in Thailand -- and Asia

technology highlights -> RHA

• Ash is ~ 18% husk

• High quality ash

• No need for disposal

• Natural pozzolan: can used as filler or additive in cement

technology highlights -> clean water

Treated wastewater will not leave the power plant site

Public participation

ATB addressed community’s concerns by…

-making regular field visits & meetings -enlisting visits by 3rd party experts-organizing field trips to operating biomass power plants-publishing ATB News

technology transfer -> training

• Training in state-of-the-art technology

• All local, Thai plant personnel

• ATB’s policy to give preference to applicants from local communities

the Social ContractATB’s Social Contract:

Environmental Protection Fund: Finances the monitoring of environmental impact on host community, provides guarantees, ensures protection.

Community Development Fund: Earmarks more than 1 million Baht for each host community to help drive local development.
