Trang 5Introduction and Background
Barbados Agricultural Management Company, Ltd (BAMC) developed a model to provide
sustainable energy from cane residue
(bagasse) This plan:
Provides vision
Diversifies energy sources
Substitutes green fuels for fossil fuels
Supports environmental stewardship
Creates added value for cane farmers
Promotes economic development
Trang 6Introduction and Background
Summarization of Project Objectives:
Investigate the viability of the fuel cane model
Evaluate the current sugar estates/cane fields, sugar
factories and sugar production
Assess the potential for power production
Provide economic and financial assessment for BAMC in the energy sector
Determine the best way forward for BAMC in developing its energy program
Provide options and alternatives to the existing model that will make it economically feasible
Trang 7Introduction and Background
Summarization of Project Benefits:
Fuel security
Ethanol fuel blends
Green fuel for electricity product
Food security
Tourism
Sustainable/renewable supply of electricity
Minimal impact on tourist areas and green spaces
Economic Growth Driver
Creates employment
Creates economic stability for cane farmers and investment confidence
Provides renewable source of power (ethanol & electricity)

Trang 11Options: Summaries
SAIL initially developed seven potential cogeneration models and ultimately nine that were taken into
consideration:
Grinding Rates
Acres of Cane in Production
Total Tons of Cane
Analysis (% Brix, % Pol, % Fiber, Mixed Juice Purity)
Products (Specialty Sugar, Molasses, Refined Sugar, Ethanol, Electricity)
Power Generation
Note: The final two models using combinations of options were developed subsequent to the last site visit in September 2005.
Trang 12Option #9 Case 2A + 1B with Combined Cycle Power
Assumed Gas Turbine Combined Cycle, Sugar Cane
& HFC, Refined Sugar, Specialty Sugar & Fuel
Ethanol (Case 2A + 1B with Combined Cycle Power)
Sugar cane: Fiber: 15.85%, Pol: 12.65%
High fiber fuel cane: Fiber: 28%, Pol: 8%
Production
– Refined Sugar (local) 12,000 metric tons
– Specialty Sugar (local) 5,000 metric tons
– Specialty Sugar (export) 10,000 metric tons
– Ethanol 14,000,000 liters/year
– Electricity (bagasse) 102,751 MWh
– Electricity (natural gas) 157,680 MW/year
Trang 13Option #9 Case 2A + 1B with Combined Cycle Power
Benefits
– High sugar production during part of the year and high fiber for electrical generation and ethanol production
during the remainder of the year
– Combined cycle makes up to 30 MW of firm power
possible
Constraints
– Need to find a suitable variety of high fiber cane
– Requires larger initial investment
Acceptable:
– Yes
Preliminary Indicative Capital Costs: $156.0 million
Trang 14Project Economics (Option 9)
Major Foreign Exchange Earnings/Import Substitution Savings
Product Quantity Savings (U.S $) Annual FOREX
Fuel Ethanol 14.4m liters/year 8.425 million
Sugar 27,000 MT per year (local/
export) 15.200 million Molasses 9,215 MT 0.844 million
Power (from fiber) 102,800 MwH 11.308 million
Power (from natural gas) Balance up to 30 Mw
(158,000 MwH)
2.897 million*
Power (from waste) 8,200 MwH 0.902 million
* Difference between using Natural Gas versus Fuel Oil/Diesel

50312 625 31.5 million
49300 525 25.9 million
49300 425 (US $25.1 million) 20.9 million
32097 425 (US $16.4 million) 13.6 million Hence, the new Project’s FOREX benefits compare favorably with historical economics
