Abstract

PROBLEM TO BE SOLVED: To solve a problem that, although natural energy utilization, such as photovoltaic power generation and wind power generation and the like, is utilized conventionally subordinately to a commercial power supply in independent power generation or in system cooperated usage utilization, recently, such an undertaking that investors participate to loan a photovoltaic power generation device on a roof of a building has appeared because of high-price purchase of electricity by power companies, and on the basis of such a background, because a time zone in which the maximum demand power of the building is generated is at a summer peak, strict maintenance is required for attending to business without damaging the environment especially in facilities that select air-conditioning as a demand control (peak-cut) target.SOLUTION: In facilities independently selling natural energy at a high price, by switching from the energy selling at a peak while being operated with demand control, the basic charge can be reduced. If facilities in which the maximum demand that determines a contract power comes at a summer peak perform the switching all over the country, it is presumed that thermal power plants corresponding to several million KW can be stopped in the country. By performing this model in IT industry and communication industry, stopping global warming of this country can be achieved immediately.

Description

  The present invention relates to a technology for rationally implementing a basic charge and usage fee of energy performed by a local government, a major company, or the like.

Currently, TEPCO's electricity tariffs have been increased by 17% in usage fees, especially at home, so the trigger was a nuclear power plant shutdown since the Great East Japan Earthquake last year, and efforts to conserve electricity The movement is spreading.
Electricity and gas charges are made up of basic charges and usage charges, but it is said that 30 minutes are measured at establishments with substations and one hour is measured for gas, but there are about 250 gas companies, peak use There are still few gas companies that adopt demand contracts (maximum demand) that determine contracts by volume.

  In addition, as for the private power receiving facilities that are said to be 770,000 nationwide, the record of peak usage for only 30 minutes as described above determines the contract power for one year. Demand power) Monitoring devices are becoming popular, but still less than 10% of the total. Furthermore, the amount of energy used in homes and condominiums pursuing a comfortable living environment continues to increase, and there are no immediate energy saving measures.

  In such a situation, the power company has decided to purchase high prices for renewable energy, so electric power consumers are paying attention to solar power generation that sells the most, especially on the roofs of condominiums and public facilities, Even if local governments are raising their hands, such as Ota City, Gunma Prefecture, they are overlooked at the time of introduction because the basic fee is a problem.

  Under the revised Energy Conservation Law, it is obliged to submit periodic reports and medium- to long-term plans to the Ministry of Economy, Trade and Industry at the responsibility of corporate managers. Therefore, in the local government, if the chief proposes to change the terms and conditions for the basic fee for the electric power company, not only can energy creation, energy saving, and energy storage be realized in public facilities, but also the energy of local production for local consumption A model that can be incorporated into the grid can be promoted.

Problems to be solved by the invention

In water purification plants, sewage treatment plants, etc., reducing water demand (maximum demand) directly leads to contract power reduction, so it is necessary to devise not to operate multiple water pumps and drainage pumps at the same time. In addition, the electric power company has created contract agreements as one contract per treatment plant, but the interpretation that the electric power has already been liberalized (public facilities in the same local government can be collectively contracted) This is an issue that should be considered as a one-way countermeasure against price increases.
Furthermore, solar power generation is purchased in full and is contracted separately from the building. However, in facilities where demand (maximum demand power) occurs during peak summer weather, it is consumed at the place where power is generated rather than being transmitted and lost. Because it seems that it is much more efficient, measures are necessary.

Means for solving the problem

Considering the fact that local governments charge for water charges and sewage charges together, water treatment plants and sewage treatment plants have different demand (maximum demand power) time zones. Significantly reduce contract power.
At the peak of the summer season when maximum demand is reached, switching the electricity sales to self-consumption, cutting the peak and leveling the load will produce a synergistic effect. There is no local government that has announced the creation of energy and the visualization of energy conservation at the same time.
And I think that it would be good to show the residents the energy supply and demand forecast as if TEPCO and Tohoku Electric are distributing the whole power in real time. In most cases, the maximum power demand (demand peak) at the water purification plant is determined to be the day off during the summer peak. For example, the water charge is from 8:30 am to 10.30 am If the terms and conditions are changed so that other times are doubled and the other time is reduced to half, contract power can be reduced by about 50% immediately. Of course, just as TEPCO and Tohoku Electric are currently distributing the total amount of power generated by each company and requesting power saving during demands, incentives are given to households, condominiums, and companies that the local government has issued and requested to save water. If it is given, it is speculated that local energy conservation and stagnant global warming countermeasures can be solved at once. By the way, if the above measures are simulated at the Asaka Water Treatment Plant in Tokyo, it is estimated that a basic fee of about 50 million yen can be saved annually.

In other words, the gist of the present invention is that the local government is not the power company's belief, but has changed the system to obtain water supply provisions when the residents save water (water charges by time zone) and contracts with the power company. There are two points to requesting a collective contract.
If the local government can adopt this collective contract system, it is speculated that even disabled people will be able to hire new employees by being indirectly involved in meter reading and become a business model that will lead to regional revitalization.

Effect of the invention

The present invention can be applied to municipal water purification plants and sewage treatment plants to reduce basic charges in the billions of units. As a source of funds, it can be used for government buildings, libraries, cultural halls, schools, etc. With the introduction of the Biscampani), it is possible to operate the facility with less than 50% of energy consumption and CO2 emission in the public facilities due to the synergistic effect of facility renovation and natural energy.
At homes and condominiums, CO2 emissions can be predicted and power, gas, and water can be saved by comparing with past hydrothermal data and environmental household account books submitted in advance. Furthermore, it is judged that energy saving action is advised by mobile mail distribution, and if it can be made into points, it will lead to the activation of the shopping street in local currency, and energy saving will be realized for each city.

The following are examples of the present invention. A conventional existing BEMS (building management system) is for controlling and starting / stopping equipment, and is not a device for instructing a new energy saving method or an emergency action. In order to prevent the water pumps from operating at the same time during the power peak at a water purification plant, the present invention is linked to the electric power company's electric vehicle forecast for customers who have registered mobile phones in advance (especially where water usage is high). Deliver time notification emails and energy-saving measures. The customer who received it returns what kind of water-saving action and power-saving action by e-mail, and makes a point with CO2 monitoring on the center side.
Unlike the meter reading performed by a conventional energy supply company, the customer can grasp the amount of water usage by time zone by reading the meter himself. In addition, the local government that received the photo mail will prove the amount of water usage by time and bill it for a fee, so it is possible to reduce the amount of hot water.

  An embodiment of the present invention in a local government is shown in FIG. The role of the energy-saving navigation center is to calculate the discharge amount by processing the photothermal water amount data from the whole navigation system sent from the water purification plant and residents.
