Abstract: The objectives of this research were to estimate available biomass quantityfrom agro-industries and agricultural residues, which could be used as energy sourcesand assessment of technical and financial potentials of cogeneration system in palm oilmills.Biomass quantity in 1997, from agro-industries and from agricultural residuesto had more than 60 million tons or 20 million tons, of oil equivalent includingamounted to straw (20 million tons), bagasse (17 million tons), corn cob (9 milliontons), cassava stalk (7 million tons) and husk (5 million tons) respectively.The representative cogeneration system requires electrical power more thansteam, steam was therefore generated in large amount for generating electrical power.The excessive steam was blownout about 20-50 % of total steam generated. For idealcogeneration system which is assumed to generated an excess electrical power about76 % of total electrical power generated.Cost analysis of electrical power and steam generated. It was found that therepresentative cogeneration system were about 0.010 US$/kWh and 0.003 US$/MJrespectively, (the cost of mix fuel is neglected) and were about 0.022 US$/kWh and0.006 US$/MJ respectively, (the cost of mix fuel is included) and the ideal cogenerationsystem will be about 0.016 US$/kWh and 0.004 US$/MJ respectively, (the cost of mixfuel is neglected) and will be about 0.023 US$/kWh and 0.006 US$/MJ respectively,(the cost of mix fuel is included).The ideal cogeneration system in case of non-firm with a payback period andinternal rate of return at about 7.7 years and 11.4 % respectively, (the cost of mix fuelis neglected) and will be about more than 20 years and less than 1 % respectively, (thecost of mix fuel is included) and case event of firm with a payback period and internalrate of return at about 5.5 years and 17.5 % respectively, (the cost of mix fuel isneglected) and will be about 10 years and 7.8 % respectively, (the cost of mix fuel isincluded).Cost analysis of electrical power from biogas of palm oil mill effluent. It wasfound that will be about 0.017 US$/kWh, in case of non-firm with a payback periodand internal rate of return at about 4.3 years and, 22.8 % respectively, in case of firmwith a payback period and internal rate of return at about 2.6 years and 39 %respectively
