By means of a Linear Programme (LP) model, an Optimal Fuel Scheduling Scheme has been obtained for the Aboadze Thermal Plant in Takoradi. The model which used weekly power output, Light Crude Oil, (LCO) delivery and inventory of the storage tanks as decision variables was solved using a computer code in Fortran. It was found out that LCO delivery to the two plants should be 25000 barrels to plant t1 and 15000 barrels to plant 2 in the first week, 23000 and 17000 barrels to plant 1 and plant 2 respectively in the second week. In the third week, the scheduled is 23000 and 18000 barrels of LCO to plant I and 2 respectively.. The inventory of the storage tanks at the end of the 3week period for the main problem was 18767 and 12169 barrels of LCO to plant 1 and plant 2 respectively. The optimal solution remained insensitive to 25% Tolerance in the model parameters.
