Control device, control method, and program for transaction of power or environmental certificate

A method causing a computer to perform:

• generating, based on power demand-supply plan information when the power demand-supply plan information indicating a power generation plan and a power consumption plan for each time zone is received,
• environmental certificate selling note data associated with a par amount and a holder ID, and
• environmental certificate purchasing note data associated with a par amount and a holder ID, and storing the data in a storage unit;
• making a contract of a future transaction of environmental certificates by,
• based on future transaction information when the future transaction information is received,
• duplicating the environmental certificate selling note data, rewriting the par amount of the duplicated environmental certificate selling note data to the same value as a contract amount, rewriting the holder ID of the duplicated environmental certificate selling note data to the same value as a purchaser ID, and storing the data in the storage unit, and
• duplicating the environmental certificate purchasing note data, rewriting the par amount of the duplicated environmental certificate purchasing note data to the same value as a contract amount, rewriting the holder ID of the duplicated environmental certificate purchasing note data to the same value as a seller ID, and storing the data in the storage unit;
• rewriting, based on power demand-supply performance information when the power demand-supply performance information is received, par amounts of the environmental value selling note data and the environmental value purchasing note data to actual values;
• and
• making a contract of a physical transaction of the environmental certificate by,
• based on physical transaction information when the physical transaction information is received,
• duplicating the environmental certificate selling note data, rewriting the par amount of the duplicated environmental certificate selling note data to the same value as a contract amount, rewriting the holder ID of the duplicated environmental certificate selling note data to the same value as a purchaser ID, and storing the data in the storage unit, and
• duplicating the environmental certificate purchasing note data, rewriting the par amount of the duplicated environmental certificate purchasing note data to the same value as a contract amount, rewriting the holder ID of the duplicated environmental certificate purchasing note data to the same value as a seller ID, and storing the data in the storage unit.

A non-transitory recording medium on which a program is recorded, the program causing a computer to perform:

• generating, based on power demand-supply plan information when the power demand-supply plan information indicating a power generation plan and a power consumption plan for each time zone is received,
• environmental certificate selling note data associated with a par amount and a holder ID, and
• environmental certificate purchasing note data associated with a par amount and a holder ID, and storing the data in a storage unit;
• making a contract of a future transaction of environmental certificates by,
• based on future transaction information when the future transaction information is received,
• duplicating the environmental certificate selling note data, rewriting the par amount of the duplicated environmental certificate selling note data to the same value as a contract amount, rewriting the holder ID of the duplicated environmental certificate selling note data to the same value as a purchaser ID, and storing the data in the storage unit, and
• duplicating the environmental certificate purchasing note data, rewriting the par amount of the duplicated environmental certificate purchasing note data to the same value as a contract amount, rewriting the holder ID of the duplicated environmental certificate purchasing note data to the same value as a seller ID, and storing the data in the storage unit;
• rewriting, based on power demand-supply performance information when the power demand-supply performance information is received, par amounts of the environmental value selling note data and the environmental value purchasing note data to actual values;
• and
• making a contract of a physical transaction of the environmental certificate by,
• based on physical transaction information when the physical transaction information is received,
• duplicating the environmental certificate selling note data, rewriting the par amount of the duplicated environmental certificate selling note data to the same value as a contract amount, rewriting the holder ID of the duplicated environmental certificate selling note data to the same value as a purchaser ID, and storing the data in the storage unit, and
• duplicating the environmental certificate purchasing note data, rewriting the par amount of the duplicated environmental certificate purchasing note data to the same value as a contract amount, rewriting the holder ID of the duplicated environmental certificate purchasing note data to the same value as a seller ID, and storing the data in the storage unit.
