Description

Rental operation system and method for solar power generation facilities {System and Method for Operating Rental of Solar Photovoltaic Power Station}

The present invention is a system and method for mutual operation of solar power generation facility rental business for the purpose of actual participation in RE100 and ESG management and practical operation of carbon emissions rights (greenhouse gas emissions rights) and calculation of rental fees (business profits) accordingly. It's about.

The world is currently experiencing a rapid increase in abnormal weather phenomena such as heat waves, floods, droughts, forest fires, and typhoons due to climate change, and is feeling a sense of crisis about the seriousness of climate change, and awareness of the need for dramatic reductions in greenhouse gas emissions is spreading. It is becoming. Amid this trend, major developed countries, led by the United Nations (UN) and the EU, have strongly advocated the need to achieve carbon neutrality by 2050 in response to climate change. Amid international pressure to declare carbon neutrality, more than 60% of countries around the world have joined the global declaration to achieve carbon neutrality by the mid-21st century. Accordingly, the Korean government also announced its intention to achieve carbon neutrality by 2050.

As such, carbon neutrality has become a major issue in the international community and is being implemented with direct binding force on implementation, such as carbon neutrality legislation, beyond the declaration of carbon neutrality. The United Nations (UN) manages carbon emissions rights through its responsible organization to manage the reduction of greenhouse gas emissions through the Clean Development Mechanism (CDM) project, and these carbon credits are traded in the market through the emissions trading system. In particular, the EU will implement a carbon border tax, a policy that imposes tariffs on products produced and imported from countries that emit more carbon dioxide than their own, in 2023 on a pilot basis in five business sectors, including steel, cement, fertilizer, aluminum, and electricity, and thereafter. We plan to pursue full introduction in 2025, and this will be implemented not only in the EU but also in the United States. As an export-dependent country, Korea is at a time when more preparations and efforts are needed to become carbon neutral and secure carbon emissions rights.

Moreover, these efforts for carbon neutrality are being expanded and promoted more realistically through the voluntary participation of global companies beyond political efforts between countries. RE100 stands for '100% Renewable Electricity', and the goal is to cover 100% of the power used by companies with renewable energy such as wind and solar power by 2050. The important thing is that the RE100 activity, which started as a voluntary campaign by global companies around the world, has become an obligation for domestic companies that supply goods to those global companies to carry out production activities using renewable energy. If a factory cannot produce products using renewable energy, it will have to spend more money to purchase carbon credits or pay a carbon tax or carbon border tax.

In addition, deep awareness of the environment caused by the climate crisis is being recognized as a social responsibility for companies and investors. A company's non-financial elements ESG (Environment, Social, and Governance) are indicators for investors to pursue long-term profits and are also a standard for consumers' active choices.

Recently, low-carbon, green growth has become a topic of national policy in Korea as well, and in order to supply and expand new and renewable energy, the government has introduced the RPS (Renewable Energy Certificate), or new and renewable energy supply certificate system, since 2012. RPS is a system that obliges power generation business operators to supply a certain percentage of total power generation as new and renewable energy. Through this system, it is intended to create a domestic market as well as business investment in new and renewable energy by domestic companies.

In particular, there is a great demand for research on related technologies to overcome the crisis of environmental change caused by the depletion of fossil energy and global warming and to support green environment and green energy policies as national growth engines. Renewable energy has emerged as an alternative, and various technologies are being developed.

Renewable energy refers to energy used by converting existing fossil fuels or renewable energy including sunlight (solar energy), wind power, hydropower (water), geothermal heat, biological organisms, etc., providing sustainable energy. Its characteristics are future energy sources for the system.

The importance of new and renewable energy has increased due to the instability of oil prices and the regulatory response to the climate change agreement. In Korea, there are eight fields of renewable energy (solar heat, solar power, biomass, wind power, small hydro, geothermal, marine energy, and waste energy) and three fields of new energy (fuel cells, coal liquefaction gasification, and hydrogen energy), a total of Eleven fields are designated as new and renewable energy by law.

Among these new and renewable energies, solar power generation is power generation using solar energy or solar heat. Solar power generation business requires obtaining a power generation business license (for example, financial capacity or technical ability required to carry out the electricity business, etc.) in accordance with the Electricity Business Act. This is a business that generates profit by purchasing and installing solar power generation facilities and then selling the electricity produced by operating the power generation facilities and SMP, REC, or carbon emissions rights (greenhouse gas emissions rights). Here, SMP stands for System Marginal Price, meaning the electricity transaction price, and REC stands for Renewable Energy Certification, and 1 REC is issued per 1 MWh for power produced using new and renewable energy. , 0.46 Ton per 1MWh is issued as a carbon emission certificate (greenhouse gas emission certificate).

Unlike coal or natural gas power plants, this solar power generation business has the advantage that even small businesses and individuals can carry out the business because it is small in scale and not very difficult to operate, but there are many restrictions on installation locations due to environmental regulations and ordinances. there is. Therefore, the rooftop solar power generation project using buildings is evaluated as environmentally friendly, but the current solar power generation project has the following problems.

First, building owners can secure electricity bill reductions and carbon emissions rights by investing their own capital to install solar power facilities on the roof of their building, but in this case, there is a problem in avoiding investment because it requires a lot of money.

Second, the most active building roof rental business currently in progress is that the building owner leases the roof of the building, which is an idle site, and the power generation facility investment company leases it and installs and operates solar power facilities. The blind spot of this business is that the building owner does not care at all. Since there are no other benefits other than a small amount of building roof rental income without ownership of the electricity and carbon emissions produced by power generation facilities, the number of participating factories is limited to a few, which is a problem that does not greatly help in expanding the supply of new and renewable energy implemented by the government. there is
