2. Description of the Related Art As described above, in a facility that owns an in-house power generation facility, at least a part of the power consumed by the in-house power generation facility is usually covered by the power generated by operating the in-house power generation facility. Insufficient power is supplied from a power company. In a facility equipped with in-house power generation facilities like this,
When the in-house power generation equipment stops operating due to periodic inspection, periodic repair, failure, or the like, the power originally generated by the in-house power generation equipment is insufficient, and it is necessary to secure the insufficient power.

[0003] Therefore, it is possible to make a contract with the electric power company for self-supply power and to receive the supply of the self-supply power as the shortage power from the power company. However, the basic charge of self-supplied electric power supplied from the power company is 10% higher than the basic charge of electric power by load factor. (If no self-supplied electric power is used, the basic charge of electric power by load factor is (30% of the 10% surcharge), which is higher than normal contract power. The power rate-specific power contract is a type of contract concluded with a power company. The more the power load factor (the ratio of the used power to the contracted maximum power) is improved, the more the power rate is discounted. belongs to.

[0004]

In a contract with an electric power company, when power is supplied together with the above-mentioned self-supplied replenishing power, the above-mentioned contract maximum power is determined by the contract power normally used and the self-supplied replenishing power. (The power generation capacity of the private power generation facility), and when the private power generation equipment owned by the user is not operated and the private power supply is not used, the load factor is reduced and the power rate is set higher. . On the other hand, if a standby power generation facility is installed that automatically switches and starts operation immediately when the private power generation facility stops, the self-supplied supplementary power will be calculated based on the power generation capacity of the private power generation facility. Since the power generation capacity is subtracted, the load factor can be slightly improved. However, even if the standby power generation facility is provided in a facility where the private power generation facility is provided, the standby power generation facility is operated only when the private power generation facility is stopped, and the operation frequency is extremely low, On the other hand, the low operation frequency has problems such as securing of installation space, increase of facility management cost and facility cost, and the economic effect of performing private power generation is reduced. Therefore, in view of the above circumstances, the present invention improves the economic effect of performing private power generation by securing private power supply at low cost in a facility provided with the private power generation facility as described above. It is an object of the present invention to provide a self-supplying power transfer method and a power generation facility.
