Introduction
Current Situation Sugarcane in Indonesia
• Total number of sugar-mill in Indonesia are 61 sugar-mill, with crushing capacity ranging 1000-12000 TCD, total crushing capacity is 225.018 TCD *)
• Total sugar-mill plantation in Indonesia is 418.259 ha (2010) which is concentrated in east java (45%) and Lampung (25%)
• Total Sugar production (2010) :2.214 Mio Tonnes Sugar, while the sugar demand is 5.4 Mio Tonnes *)
• Indonesian sugarmill Factories: mostly were old factories need to improve performance
• off-season, existing boiler and turbine is not operated,while one unit of a new boiler operates at 47.4 TPHand new turbine operate with condensing mode at9.975 MW (10 MW).

Conclusion
• Bagasse Surplus can be utilize to produce electricity through cogeneration system in sugarmill (send to grid) , (7200 TCD 71.5 GWhr/year)
• The net electricity production will be of about 71.5 GWh will distributed to the grid as electricity sales that generate revenue annually about IDR 58.648 billion base on electricity selling price of IDR 820/kWh
