ROI-ET Green Power Project
ROI-ET Green Company Limited
Biomass : Organic matters:
Firewood, Rice husk, Bagasse, Woodscrap, Rice straw, Palm shell, Coconut shell, etc. and other agricultural wastes
Animal manure
Waste product form agro-industrial plants
Rubbish
Experience of Rice Husk Power Plant in Thailand
Thailand is mainly an agricultural country :Abundance of agricultural residuals Left over of residual, no value gained Disposal cost
Since 1995, National Energy Policy office (NEPO) :Policy of energy conservationRenewable energy as alternativeFeasibility study
History of Biomass in Thailand
Reduce pollution caused by left over of residuals Reduce Greenhouse effect caused by natural decay (Methane : CH4) and use of fossil fuels as well as utilization of residuals (CO2) Reduce import of fuelReduce electricity total system loss Increase stability of electricity system in area of generation Lower cost of fuel compared with fossil fuelImprove living of people and community
Economics : Local community’s revenueSocial & Cultural : Soil improvement by ash, Environment,
: Residue disposalEducation : Technology & Environmental friendly
Benefits
Higher investment cost of equipment per MW. (>1.2 M. USD)Higher cost of fuel storage and transportationFuel availability is not firm:
SeasonalClimate Export market of main product Government policyUncertain amount of local utilization
Variation of moisture, difficult control combustion Higher corrosion in fuel & ash pathsImplementation of same kind of project in the areaPoor environmental management could cause pollution
Constraints & Threats

• LHV of Fuel : 12.6 MJ/kg (3,000 kcal/kg)
• Water Supply : Chi River, ~13.6 km pipeline
• Connection : 22 kV line PEA
• Installed Capacity : 9.95 MW
• Contracted Capacity with EGAT : 8.8 MW
• Contract period : 21 years
