Installed capacity, generating capacity and prospect of biogas power generation

First, the development of biogas power generation industry

Biogas generator refers to a power generation system that uses biogas to generate electricity. China's biogas started in the 20th century from the 1920s to the 1930s, as early as 1929 in Shantou city, Guangdong Province, China's first biogas promotion agency was established. Before liberation, biogas utilization throughout the country's 13 provinces, but basically in a sporadic scattered application state, China's biogas power generation industry development history is as follows:

Second, biomass power price subsidy policy

Biomass power generation implements a divided electricity price policy, among which, biogas power generation implements a "benchmark price + fixed subsidy" electricity price policy, and agricultural and forestry biomass power generation and waste incineration power generation implement a unified national benchmark electricity price policy. Encourage the selection of project investors through bidding, the bid price shall not be higher than the electricity price standard set by the state. The part of the on-grid price of the biomass power generation project that is higher than the local benchmark price of coal-fired power generation will be compensated through the central financial subsidy funds and provincial financial funds.

Iii. Analysis of the development status of China's biogas power generation industry

1. Biomass power generation structure

In 2021, the annual power generation of biomass power generation in China will reach 163.7 billion kW·h, an increase of about 23.6%. The proportion of total power generation reached 2.0%, an increase of 0.2 percentage points year-on-year. Among them, the annual power generation of agricultural and forestry biomass reached 51.6 billion kW·h, accounting for 31.5%; The annual power generation of waste incineration reached 108.4 billion kW·h, accounting for 66.2%; The annual power generation of biogas reached 3.7 billion kW·h, accounting for 2.3%.

2. Installed capacity

With the continuous progress of comprehensive utilization of biogas technology, biogas power generation as an emerging biogas utilization technology appears in everyone's vision, in recent years, China's biogas power generation cumulative capacity continues to grow, according to statistics, as of 2021 China's biogas power generation cumulative installed capacity of 1.11 million kilowatts, new installed capacity of 220,000 kilowatts.

3. Power generation

In recent years, with the support of a series of policies, the development of biogas industry in China has experienced a process from small to large and from scratch. According to statistics, in 2021, the annual power generation of biogas in China will reach 3.7 billion kW·h, which is basically the same as that in 2020.

Iv. Analysis of the competitive pattern of China's biogas power generation industry

1. Number of enterprises

Biogas power generation is a widely distributed and inexpensive distributed energy, enterprise check data show that in 2021, related companies registered 118 new, down 63%.

2. Key enterprises

At present, Minhe Shares are mainly engaged in breeding chickens on behalf of parents and slaughtering and processing commercial chickens, of which commercial chicken seedlings are the main profit source. A special subsidiary was established to centrally treat the manure produced in the company's breeding process. Developed a set of best manure treatment technology and recycling technology: manure through anaerobic fermentation, the resulting biogas for power generation and biogas purification; According to statistics, as of the first half of 2022, the income of Minhe biogas power generation business was 0.06 million yuan, an increase of 0.65%, accounting for 0.92% of the total operating income.

Since its establishment, Baichuan Changyin has focused on biogas power generation business and accumulated rich experience in operation and management. Baichuan Changyin operates a large number of biogas power generation projects, which has formed a relatively obvious scale advantage. According to statistics, as of the first half of 2022, Baichuan Changyin biogas power generation revenue was 218 million yuan, down 5.98% year-on-year, accounting for 94.76% of total operating revenue.

V. Prospects of China's biogas power generation industry

The "14th Five-Year Plan" period is a key period for China to promote "carbon peak, carbon neutrality", deeply implement the rural revitalization strategy, increase urban and rural environmental governance and build a modern energy system, and the biomass power generation industry will usher in new development opportunities. It is manifested in:

1, biomass power generation overall maintained steady growth

The growth and rigid treatment needs of urban and rural organic waste will promote the continued growth of the biomass power generation industry, but the growth differentiation characteristics of different types of power generation projects are also more obvious. Among them, domestic waste incineration power generation will continue to grow rapidly, continue to serve as the main growth engine of biomass power generation industry, agricultural and forestry biomass power generation, biogas power generation will maintain a small growth.
