Abstract

A memory unit stores selling electricity income data; profit data from the selling electricity, electricity generation cost at power plant, domestic carrying-in cost from the discharge at a discharge port to the carrying-in the power plant, importation cost from the shipping port of the producing country to the discharge port, and producing country carrying-out cost data from exploitation of the fuel through an oil refinery to the carrying-out to the discharge port. A calculation unit calculates a netback whole value of the fuel by subtracting an amount of profit data and an amount of electricity generation cost from an amount of the selling electricity income data.

Claims

1. A method of assisting price determination of fuel for electricity generation using a computer system having a calculation device and a memory device,

wherein the memory device memorizes selling electricity income data by an electricity generation enterprise using the fuel, profit data in the profit by the enterprise using the fuel, electricity generation cost data required for electricity generation using the fuel carried into a power plant, domestic carrying-in cost data in cost required for carrying-in of the fuel from a discharge port to a power plant, importation cost data required for the carrying-out from a shipping port of a producing country to the discharge port, and producing country carrying-out cost data in a cost required for exploitation of raw material, a fuel refinery and carrying-out to the shipping port, and

wherein the calculation device carries out a step for calculating a netback whole value of the fuel by subtracting an amount in profit data and an amount in the electricity generation cost, both being memorized in the memory device, from an amount of the selling electricity income data memorized in the memory device, a step for calculating a netback price of the fuel by subtracting the amount in the importation cost and the amount in the producing country carrying-out cost data, both being memorized in the memory device, from the netback whole value of the fuel, and a step for outputting a netback price of the fuel to an output device of the computer system.

2. The method of assisting price determination of fuel for electricity generation according to claim 1,

wherein the selling electricity income data, the profit data, the electricity generation cost data, the domestic carrying-in cost data, the importation cost data, and the producing country carrying-out cost data of a period in the past are memorized in the memory device,

wherein before carrying out the netback whole value calculation step, the calculation device carries out a step for accepting designation of a calculating timing of the netback price of the fuel from an operator by means of the input device of the computer system, a step for presuming an selling electricity profit, a profit, an electricity generation cost, a domestic carrying-in cost, an importation cost, and a producing country carrying-out cost in the designated period for computation in accordance with data memorized in the memory device that includes the selling electricity income data, the profit data, the electricity generation cost data, the domestic carrying-in cost data, the importation cost data, and the producing country carrying-out cost data of the respective periods,

wherein the step for calculating the netback whole value carries out calculation of the netback whole value of the fuel at the designated period, using the presumed income from selling electricity, profit, electricity generation cost, and

wherein the netback price calculation step carries out calculation of the netback price in the designated calculation period, using the netback whole value, the presumed domestic carrying-in cost, the importation cost, and the producing country carrying-out cost.

3. The method of assisting price determination of the fuel for electricity generation according to claim 1,

wherein the calculation device further carries out acceptance of selection from an operator as the object for the calculation of the netback price among the fuel before exploitation of the raw material, the fuel at the time of carrying-out from the shipping port, and the fuel at the time of the fuel carrying-in the power plant.

4. The method of assisting determination of a price of the fuel for electricity generation according to claim 1,

wherein the computation device carries out memorizing in the memory device by inputting at least one of data from a server for administration of selling electricity income data, the profit data, the electricity generation cost data, the domestic carrying-in cost data, the importation cost, and the producing country carrying-out cost data by means of a communication device of the computer system.

5. An apparatus for fuel price determination for power generation, which comprises a memory device, a computation device and an output device,

wherein the memory device memories selling electricity income data using the fuel by a electricity generation enterprise, a profit data in a profit from electricity generation by the electricity generation enterprise, a electricity generation cost data in a cost required for electricity generation using the fuel carried into the power plant by the electricity generation enterprise, a domestic carrying-in cost data in a cost required during the discharge of the fuel at a discharge port through carrying of the fuel into the power plant, an importation cost data in an importation cost during the carrying-out of the producing country through the discharge port, and a producing country carrying-out cost data in a cost required during exploitation of the fuel raw material through the refinery of the fuel to the carrying-out to the shipping port, and

wherein the computation device carried out a netback whole value calculation processing for calculating the netback whole value by subtracting an amount of the profit data and amount of the electricity generation cost memorized in the memory device from an amount of selling electricity income data memorized in the memory device, a netback price calculation processing for calculating the netback price of the fuel by subtracting an amount in the importation cost data and an amount of producing country carrying-out cost data memorized in the memory device from the netback whole value of the fuel, and a netback price outputting processing for outputting the netback price to the output device.

6. A program readable with a computer system for supporting determination for electricity generation fuel,

wherein there are memorized in a memory device, an selling electricity income data in the selling electricity income using the fuel by a electricity generation enterprise, a profit data in a profit from electricity generation using the fuel by the electric generation enterprise, a electricity generation cost data required for electricity generation using the fuel carried-into the power plant by the enterprise, a domestic carrying-in cost data in a cost required during discharge at a discharge port through carrying of the fuel into the power plant, and a producing country carrying-out cost data in a cost required during exploitation of raw material of the fuel through a refinery to the discharge port, and

wherein the program makes the computation device carrying-out a netback whole value calculation step for calculating the netback whole of the fuel by subtracting an amount represented by a profit data and an amount represented by an electricity generation cost memorized in the memory device from an selling electricity income data memorized in the memory device, a netback price calculation step for calculation of the netback price of the fuel by subtracting an amount of an importation cost and an amount represented by a producing carrying-out cost data memorized in the memory device from a netback price value of the fuel, and a netback price outputting step for outputting the netback price of the fuel to an output device of the computer system.
