EMISSION FACTOR CALCULATING APPARATUS AND EMISSION FACTOR CALCULATING METHOD
First Claim
1. An emission factor calculating apparatus comprising:
- a receiving unit configured to receive an emission factor of a higher-level system at first regular intervals;
a received electricity measuring unit configured to measure, as a received electricity, electricity received from the higher-level system and accumulated;
a generated electricity measuring unit configured to measure electricity generated with zero emission in a target system; and
an emission factor calculating unit configured to calculate a substantial emission factor of the target system at second regular intervals, based on a ratio between the received electricity and the measured electricity generated, and the emission factor of the higher-level system, the emission factor calculating unit informing a load or a lower-level system of the substantial emission factor.

Abstract
According to one embodiment, an emission factor calculating apparatus includes a receiving unit, a received electricity (i.e., electric power) measuring unit, a generated electricity measuring unit, and an emission factor calculating unit. The receiving unit receives an emission factor of a higher-level system at first regular intervals. The received electricity measuring unit measures, as a received electricity, electricity received from the higher-level system and accumulated. The generated electricity measuring unit measures electricity generated with zero emission in a target system. The emission factor calculating unit calculates a substantial emission factor of the target system at regular intervals (i.e., at a fixed interval), based on a ratio between the received electricity and the measured electricity generated, and the emission factor of the higher-level system. The emission factor calculating unit informs a load or a lower-level system of the substantial emission factor.
