On May 17, the Ministry of Ecology and Environment issued the "Carbon Emission Rights Registration Management Rules (Trial)", "Carbon Emission Rights Trading Management Rules (Trial)" and "Carbon Emission Rights Settlement Management Rules (Trial)", which will be implemented immediately. According to the Regulations on the Administration of Carbon Emission Trading (Trial), carbon emission quota trading takes the "price of carbon dioxide equivalent per ton" as the unit of pricing, and the minimum change in the declared volume is measured
as 1 ton of carbon dioxide equivalent, and the minimum change in the declared price is measured as 0.01 yuan.Trading institutions to implement the rise and fall limit system. A trading institution shall set the proportion of the rise and fall of different trading methods, and may adjust the proportion of the rise and fall according to the market risk situation.
This marks the national carbon emission right trading work and a big step forward!
First of all, we need to figure out a question, why the implementation of carbon emissions trading will benefit photovoltaic power stations?
We know that industrial and commercial photovoltaic power stations can pay back their investment costs in about 5 years.With the opening of national carbon emission quota trading, users or investors who own photovoltaic power stations get a pie from the sky. According to the "Clean Production Research Report on China's Photovoltaic Industry" released by the Renewable Energy Committee of the China Association of Comprehensive Utilization of Resources and the international environmental organization
Greenpeace, the energy recovery cycle of photovoltaic power generation is only 1.3 years, while its service life is 25 years, which means that photovoltaic power generation will have zero carbon emissions for about 24 years.According to the calculation, the carbon dioxide emission of photovoltaic power generation is 33-50 grams/kWh, while that of coal power generation is 796.7 grams/kWh.With carbon dioxide emissions only one-tenth to one-twentieth of those of fossil fuels, photovoltaic power has an overwhelming advantage in reducing carbon emissions.
According to article 31 [offsetting mechanism], CCER (Nationally Certified Voluntary Emissions Reduction) for renewable energy development can be used to offset 5% of verified emissions.
According to our experience in developing CCERs for PV projects, a 100MW PV project can develop 110,000 tons of CCERs per year, with a maximum of 21 years of development during its full life cycle, and a maximum of 2.31 million tons of CCERs during its full life cycle. According to the current CCER transaction price of 20 yuan/ton in Beijing, a 100MW photovoltaic power station can gain an additional income of 46.2 million yuan through carbon trading, which is equivalent to 1.5 years' generating income and
2.3 cents per kilowatt-hour.This part of revenue can effectively reduce the LCOE by about 7% (based on the annual utilization hours of 1000 hours, the on-grid electricity price is 0.3 yuan /kWh), which can ensure the photovoltaic power stations across the country to achieve affordable or even low-cost access to the Internet, with significant economic and environmental benefits.
