Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric power investment system and an electric power sales system for promoting the introduction of green power generation.

[0002]

2. Description of the Related Art The coming 21st century is called the century of the environment.
It is an important issue that cannot be avoided in the 21st century, such as ozone hole, desertification, acid rain, marine pollution, soil pollution, energy problem and deforestation, triggered by global warming. The planet is likely to be catastrophic if appropriate actions are not taken early on at the global level. Under such circumstances, in Japan, starting with COP3 held in Kyoto in 1997, acquisition of ISO 14000 by listed companies and voluntary reporting of environmental accounting, the revised Ministry of Energy and Environmental Affairs Act of 1999, and enforcement in the future are scheduled. As regulations on the environment, such as the Home Appliance Recycling Law, have increased, public awareness of the environment has grown year by year. As typified by the so-called “green consumer,” some people are becoming more aware of the environment when purchasing goods and enjoying services. One survey found that women who buy more environmentally friendly products at higher prices are more likely to save women than men when they are older, have a higher degree of education, and have more household savings. It has been found that more and more, as a result, has a high support layer of 60% or more.

[0003] Also, as symbolized by "eco-funds" that are starting to attract attention recently, there is a movement to highly evaluate the rating of a company that is active in the environment as a whole society.

[0004] Regarding energy, in COP3, Japan has pledged a worldwide reduction of 6% in CO2 equivalent in 2010 compared to the 1990 level. However, in recent years, energy consumption has been
Although it has been almost flat since 1998, it has been increasing at a rate of several percent each year, mainly in the consumer and transport sectors, and energy saving has not progressed at all. Japan, which has scarce resources, does not rely only on thermal power, but has a so-called best mix of hydropower and nuclear power, but nuclear power that does not emit CO2 does not proceed as expected because of opposition from local residents. Electricity companies have become extremely cautious about new large-scale power generation sites due to the increase in CO2 emissions and the partial opening of the electricity retail business due to the deregulation of the Electricity Business Law that began in March this year. On the other hand, there is an increasing need for such a centralized power supply for a distributed power supply centered on a cogeneration system of about 3,000 kW capable of supplying both electricity and heat to a large-scale building.

[0005] Under such circumstances, attention has been given to distributed power generation using so-called natural energy such as solar power generation and wind power generation. Photovoltaic power generation has been spread to some extent due to measures such as subsidies for ordinary households and price reductions made by solar cell manufacturers. On the other hand, wind power has come into the spotlight since 1998 when existing power companies introduced a long-term preferential purchase system for large-scale wind power. As a result, domestic power generation capacity increased sharply from 388,000 kW in 1998 to 83,000 kW in 1999, mainly in areas with relatively high annual average wind speed, such as Hokkaido, Tohoku, and Okinawa. The Ministry of International Trade and Industry and the Agency for Natural Resources and Energy have set a target of 300,000 kW for wind power generation in 2010, but have begun reviewing the target in order to increase the amount. In response to this trend, bipartisan parliamentarians have imposed obligations on power companies to purchase electricity from renewable energy sources, such as wind and solar power, while at the same time the state has supported some of the costs. We are working on the enactment of the "Renewable Energy Power Generation Promotion Act" aiming to spread power generation.

[0006]

However, there are still problems to be solved regarding green power generation. For example, photovoltaic power generation has the advantages of being able to be installed near customers, having no operating parts, and being symbolic and environmentally appealing. This is one of the issues. In order to overcome economic problems, the Ministry of International Trade and Industry (NEF) has been implementing the “Residential Solar Power System Monitoring Project” since 1994 and has provided some subsidies for installation costs. Under this system, 3,59 in 1994-96
0 cases, about 13,000 kW were introduced, and the system price and the effect of mass production have been affected. The system has been reduced by about 40% compared to before the start of the system. It is undeniable that the cost is very high. That is, a system of about 3 kW that is widely used in homes costs slightly more than 3 million yen including installation costs, and the burden on each home is about 2 million yen even if NEF subsidies are considered. Considering that the household electricity bill is about 120,000 to 180,000 yen per year, this amount is for the case where the entire household electricity is applied by the amount of solar power generation.
It will take about 5 years. This is 22 years or 24 years, which is the useful life of a wooden house (according to "Appendix Table of useful life of tangible depreciable assets other than machinery and equipment" in "Ministerial Ordinance on the Useful Life of Depreciable Assets";
(Specified service life of different types), and its widespread acceptance in ordinary households would be difficult, even considering the advantages of environmentally friendly systems. The cost of home inverters is about 300,000 yen, but it is difficult to use them for the above-mentioned 25 years because the product is incomplete and inefficient. Is necessary). In addition, to introduce to existing buildings such as buildings,
There are considerable costs for incidental works such as waterproofing work, so considerable costs are incurred and the introduction is limited. It has already been decided in 2002 to stop the subsidy program.

On the other hand, regarding wind power generation, it is said that a relatively large wind power generator of 300 kW or more is profitable at an average wind speed of 6 m or more, but generally, wind power generation is located far from a place where power demand is high. Usually, it is necessary to sell the power directly to the power company or to transfer the power using the existing transmission line from the installation site, so in any case, negotiation with the existing power company becomes a barrier There are also limitations due to factors such as the location of the location, good wind conditions, noise from wind power generation, and landscape problems.

[0008] Furthermore, the biggest weakness of the power generation using such natural energy is that it is greatly affected by natural conditions such as weather, that is, the sun and the wind are left. Buildings and other buildings cannot be powered.

Consumers are becoming more and more interested in power generation using natural energy, and the number of consumers who want to contribute to the environment even if the cost is somewhat higher, such as "green consumers", is increasing. The biggest problems with solar power are that the price is still too high, and that wind power has to be installed far away from general consumers.

Further, the green power generation equipment itself is quite expensive, and the future is uncertain, considering the future, even if it is an individual or a company alone of a certain scale. It is a difficult situation.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a power investment system and a power sales system that promote the introduction of green power generation. .

[0012]

To solve the above-mentioned conventional problems, a power investment system according to a first aspect of the present invention provides a green securities obtained by securitizing the asset value of a green power generation facility via the Internet. It is characterized by managing investors who sell and purchase green securities.

According to the present invention, an investor can invest in green power generation while staying at home or the like, and therefore, the introduction of green power generation can be promoted.

In the power investment system according to claim 2 of the present invention, in the power investment system according to claim 1, the public offering for the purchase of the green securities is performed via the Internet. Simply apply, you can buy green securities, so

According to a third aspect of the present invention, in the power investment system according to the first aspect, the value of the green securities is notified to a computer of the investor.

According to the present invention, for example, the value of the green securities calculated based on the operation status such as the amount of power generated by the green power generation facility is notified to the investor's computer. This will increase the willingness to invest and, for this reason, promote the introduction of green power. Further, it is preferable that the change of the value of the securities purchased by the investor from the past to the present is visually displayed as a graph or the like, so that the investor's willingness to invest can be further enhanced.

According to a fourth aspect of the present invention, there is provided a power selling system for selling, via the Internet, green power generated by a green power generation facility and power generated by a power generation facility other than the green power generation facility as the same power brand. In addition, it manages the consumers of the power from which the power has been purchased.

According to the present invention, a consumer can purchase green power and normal power via the Internet, so that the customer is willing to purchase green power without having to bother to purchase these powers separately. Therefore, introduction of green power generation can be promoted.

A power selling system according to a fifth aspect of the present invention is the power selling system according to the fourth aspect, wherein a power rate is displayed on a computer of the customer connected via the Internet. I do.

In the present invention, the fee may be displayed, for example, in the form of a bill issued monthly.
