Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for calculating a charge according to the amount of resources used, such as gas, electric power, water, and communication lines, and a computer program for realizing this apparatus by a computer. Regarding the medium.

[0002]

2. Description of the Related Art The consumption of electric power, which is one of the resources, is greatest in summer throughout the year. The main reason is that the cooling load increases. As a result, the power supply companies will prepare for the increase in power demand in summer by expanding the facilities, but when the power consumption becomes less than in summer, some of the facilities will become surplus and the utilization efficiency of the facilities will decrease I do.

On the other hand, gas consumption is highest in winter throughout the year. The main reason is that the heating load increases. As a result, gas suppliers are planning to expand their facilities and prepare for the increase in gas demand in winter, but this will result in a surplus of equipment at other times when gas consumption is lower than in winter, resulting in reduced utilization efficiency of facilities. I do.

[0004] Therefore, if part of the electricity demand in summer can be replaced by gas and part of the gas demand in winter can be replaced by electric power, each energy supplier can prepare for seasonal increase in demand. It is not necessary to make useless capital investment. If unnecessary capital investment can be avoided, it will also contribute to resource saving. Further, if the transfer to alternative energy is promoted, the peak demand for electricity is eased in the summer season, and the peak demand for gas is eased in the winter season.

[0005] Further, as a countermeasure for energy, CO ₂ is used on a national scale.
In order to reduce greenhouse gas emissions, the majority of the population will need to switch to cleaner alternative energy to achieve this.
In order to promote the switch to such large-scale alternative energy, it is necessary not only to raise the awareness of environmental issues among individual consumers but also to provide strong economic incentives for the transfer. Giving is effective.

[0006] Further, promotion of energy saving is an important issue in order to protect the global environment. However, if the replacement of old equipment with low energy efficiency with equipment with high energy efficiency is promoted, the comfort of customers will be sacrificed. Energy saving can be easily achieved to some extent without doing so. Providing the customer with a merit that exceeds the economic burden of replacing equipment will promote such replacement and lead to energy savings.

[0007]

By the way, in order to utilize the alternative energy, load equipment is newly purchased, for example, by replacing the power cooling equipment with the gas cooling equipment and replacing the gas heating equipment with the power heating equipment. Must. As described above, the transfer to the alternative energy imposes an economic burden on the consumer, and thus it is difficult to promote the transfer to the alternative energy.

If a new gas pipe is laid in a region where city gas is not supplied and a new capital investment is made in order to switch to alternative energy, the consumption of city gas in that region must increase. If so, it will be difficult to recover the investment.
As a means of promoting customers' consumption of city gas, it is effective to provide toll-based services such as discounting rates as consumption increases, but the current rate system is uniform and alternative It is difficult to promote the transfer to energy.

[0009] Further, as the energy consumption increases, the cost is set higher to raise the customer's cost awareness, or the price of the old device with low energy efficiency is set higher, so that the old device can be replaced. Promoting the replacement of new equipment with high energy efficiency is effective in promoting energy savings.However, the current rate system is uniform, so customers can be more cost-conscious and It is difficult to provide consumers with sufficient motivation to promote replacement of equipment.

The present invention has been made in order to solve such problems. For example, it is possible to reduce a gas rate in summer when power consumption peaks or to reduce a gas rate in winter when gas consumption increases significantly. When energy consumption is concentrated on one energy, such as by lowering the electricity rate, and lowering the usage rate of other energy to promote the transfer to alternative energy, it is possible to increase seasonal demand such as a season. Calculate fees that will contribute to resource savings while avoiding excess equipment due to unnecessary capital investment, which will contribute to alleviating the peak demand for electricity in summer, the peak demand for gas in winter, and reducing CO ₂ emissions. It is an object of the present invention to provide an apparatus and a recording medium in which a computer program for causing a computer to realize the apparatus is recorded.

[0011] The present invention also reduces the gas consumption for heating, for example, as the consumption of heating gas increases, and promotes the transfer of heating energy from kerosene to gas. In addition to promoting gas prices, by reducing gas prices in line with the increase in electricity consumption, we will diversify the tariff system, activate competition among operators, and calculate charges that contribute to reducing energy prices. It is an object of the present invention to provide an apparatus for performing the above, and a recording medium in which a computer program for causing a computer to realize the apparatus is recorded.

[0012] The present invention also provides, for example, an increase in telephone charges as gas / electric power consumption increases, and an increase in gas / electric charges as automobile mileage increases. To promote energy saving of gasoline, gas, electric power, etc. by raising the consumer's cost awareness of, and promoting the replacement of old equipment with low energy efficiency to new equipment with high energy efficiency. It is an object of the present invention to provide an apparatus for calculating an appropriate fee and a recording medium on which a computer program for causing a computer to realize the apparatus is recorded.
