Leading global industrial development
Promoting clean and low-carbon transformation
——"Thirteen "Five" Solar Energy Development Overview
These are 5 years of breakthrough and improvement. The photovoltaic industry completed the "13th Five-Year Plan" installation target in just two years. Three international standards led by China in the solar thermal power generation industry lead the development of the global industry. Polycrystalline silicon, components , cell production capacity has ranked first in the world for many years. The continuously updated records have become the best proof of the progress of the industry.
This has been five years of optimization and upgrading. The consumption situation in various regions has continued to improve, the light abandonment rate and the amount of light abandoned have "double dropped" year after year, and the intensity of subsidies continues to decline. The continuous optimization of the industrial structure injects more vitality into the high-quality development of the industry.
During the "Thirteenth Five-Year Plan" period, my country's solar energy industry continued to make breakthroughs, deepened innovation, and became increasingly perfect, writing a colorful development picture.
Completed the installation target two years ahead of schedule
The consumption situation continues to improve
If you use one word to describe the development of the solar energy industry during the "Thirteenth Five-Year Plan", it must be "unexpected." Breaking through industry expectations time and time again, it has become the best gift given by solar energy to promote the transformation and development of clean and low-carbon energy in our country.
At the beginning of the “Thirteenth Five-Year Plan”, the “Thirteenth Five-Year Plan for Solar Energy” clearly stated that “by the end of 2020, the installed capacity of photovoltaic power generation will reach more than 105 million kilowatts”, pointing out the direction for the development of my country’s photovoltaic industry. What is unexpected is that by the end of 2017, my country's cumulative installed photovoltaic power generation capacity reached 130 million kilowatts, achieving the "13th Five-Year Plan" photovoltaic installation guidance target ahead of schedule.
Under the guidance of the National Energy Administration and relevant departments, the photovoltaic power generation industry has chosen to "ride the wind and waves" and continue to stride forward. As of the end of October 2020, my country's installed photovoltaic power generation capacity reached 228 million kilowatts, more than doubling the target of the "13th Five-Year Plan". Its new installed capacity has remained first in the world for eight consecutive years, significantly exceeding industry expectations. It has become a new “China business card”.
During the "Thirteenth Five-Year Plan" period, thanks to factors such as the continued rapid growth of electricity load, the continuous optimization of the construction layout of renewable energy projects, and the continuous strengthening of power grid dispatching and operation assessment, while the scale of photovoltaic power generation installed capacity has grown rapidly, it has been troubled for a long time. The consumption problem of industry development is gradually being alleviated.
According to statistics from the National Energy Administration, in the first ten months of 2020 alone, my country's photovoltaic power generation reached 223 billion kilowatt hours, a year-on-year increase of 16.7%, ranking first in the world. At the same time, my country's photovoltaic power generation utilization rate reached 98.3%, a year-on-year increase of 0.2 percentage points, and an increase of 9 percentage points from the end of the "Twelfth Five-Year Plan". The consumption situation continues to improve, providing strong support for promoting high-quality energy development.
From "two ends outside" to the world's leading
The pace of industrial transformation and upgrading is accelerating
In the past, my country's photovoltaic power generation industry was only the "factory" for the photovoltaic industry in developed countries such as Europe and the United States. The dilemma of "two ends outside" made the development of the industry difficult. In recent years, thanks to the strong support, encouragement and guidance of the National Energy Administration and other energy authorities, my country's photovoltaic power generation industry chain system has been increasingly improved, and remarkable achievements have been made in the fields of equipment manufacturing and system application. Now it has established an integrated system ranging from upstream high-purity crystalline silicon production to midstream The vertically integrated system from the production of high-efficiency solar cells to the construction and operation of terminal photovoltaic power stations has formed a complete photovoltaic new energy industry chain with independent intellectual property rights, providing strong support for the industry to seize the global market.
According to industry statistics, in 2020, my country's polysilicon, silicon wafer, cell and module production capacity accounted for 69.0%, 93.7%, 77.7% and 69.2% of the world respectively, an increase of 7.4, 2.9, 4.0 and 0.9 percentage points respectively. , with its product capacity and output ranking first in the world, it has become one of the main driving forces for the development of the global photovoltaic industry. High-quality development of
requires not only a quantitative increase, but also a qualitative improvement. While the installed capacity is growing rapidly, the conversion efficiency of solar cells and modules in my country's photovoltaic industry is also constantly updating records.As of the end of 2019, the average conversion efficiency of large-scale production of single and polycrystalline cells has increased by approximately 4 and 3 percentage points respectively compared with 2015. The average conversion efficiency of advanced cells such as heterojunction cells has reached 23.0%. A number of technological innovations have led the development of the global industry. . my country's photovoltaic industry has gradually transformed from a world processing base with "two ends outside" to a global photovoltaic development innovation and manufacturing base for the entire industry chain.
What’s even more gratifying is that with the strong promotion of the large-scale development of the entire industry chain and the unified bidding of projects across the country, photovoltaic power generation companies continue to strengthen system optimization and cost control, effectively reducing project costs. The average cost of photovoltaic power generation units in 2019 was relatively high. In 2015, the price dropped by about 49%, reaching about 4,000 yuan/kilowatt, laying an important foundation for the industry to achieve affordable access to the Internet.
During the "Thirteenth Five-Year Plan" period, my country's solar thermal power generation industry has also achieved great development. Since the National Energy Administration announced the first batch of solar thermal power generation demonstration projects in 2016, the development of my country's solar thermal power generation industry has continued to accelerate. As of the end of 2019, the cumulative installed capacity reached 420,000 kilowatts, accounting for 6% of the world, and there were nearly 300 major related companies in the industry chain. . At the same time, the Delingha 50-MW solar thermal power station, one of the first batch of demonstration projects, has achieved full load operation, and the depth and speed of peak regulation are significantly better than conventional thermal power.
It is worth mentioning that the proposal "Performance Test Procedures for Trough Solar Thermal Power Station Thermal Collection System" led by China General Nuclear Power Corporation has also successfully passed the voting and project approval, becoming the third international standard in the field of photothermal led by my country and setting the standard for my country's solar energy industry. Another shining star has been added to the long history of industry development.
Simultaneous efforts in poverty alleviation and environmental protection
The advantages of new energy are becoming increasingly prominent
"Photovoltaic power generation can kill two birds with one stone. It not only helps the poor but also develops new energy. We must increase support."
"Implement photovoltaic poverty alleviation in places with photothermal conditions. , building village-level photovoltaic power stations... is a good way to solve deep poverty."
...
General Secretary Xi Jinping’s sincere instructions have pointed out the direction for poverty-stricken areas to win the battle against poverty. Photovoltaic poverty alleviation projects have become a powerful weapon for poverty-stricken areas to enhance their economic development vitality and development potential.
Since the launch of photovoltaic poverty alleviation work in 2015, the national level has issued special construction scales or plans for photovoltaic poverty alleviation in five batches, and has given special support to photovoltaic poverty alleviation in the management of photovoltaic power generation scale. It has encouraged various localities to use commercial photovoltaic indicators to build photovoltaic poverty alleviation projects, and contributed to photovoltaic poverty alleviation. Plan the development path of the project and make adequate preparations.
With the joint efforts of various regions and departments, photovoltaic poverty alleviation work has achieved remarkable results during the “13th Five-Year Plan” period. Up to now, the construction tasks of photovoltaic poverty alleviation projects have been fully completed, and a total of 26.36 million kilowatts of photovoltaic poverty alleviation power stations have been built, benefiting 60,000 poor villages and 4.15 million poor households, and generating an annual electricity bill and subsidy income of approximately 18 billion yuan. Photovoltaic poverty alleviation has become a new business format for poverty-stricken counties to promote industrial poverty alleviation. It is an important industrial support for the collective economy of poor villages to "break zero" and has made an important contribution to my country's achievement of the goal of comprehensive poverty alleviation in 2020 ahead of schedule.
In addition to the solemn promise that "no one can be missing on the road to prosperity", my country's photovoltaic power generation industry also shoulders the historical trust of promoting my country's clean energy transformation.
In early November 2020, the Ministry of Ecology and Environment released two drafts for comments, the "National Carbon Emissions Trading Management Measures (Trial)" and the "National Carbon Emissions Registration and Trading Settlement Management Measures (Trial)", disclosing the national carbon emissions trading market. The basic operating rules clarify that the national certified voluntary emission reduction (hereinafter referred to as "CCER") offset mechanism is an important part of the carbon emissions trading system. Since then, emission reduction projects such as photovoltaic power generation can sell their carbon emissions on the national carbon market. It is understood that as of December 8, 2020, as one of the first batch of carbon emissions trading pilots in my country, the Shenzhen carbon market quotas launched in 2013 have a cumulative total trading volume of approximately 58.06 million tons, and a total transaction volume of approximately 1.38 billion yuan, which is Make outstanding contributions to regional green and low-carbon development.
Judging from the experience of developing CCER in photovoltaic projects, a 100-megawatt photovoltaic project can develop 110,000 tons of CCER every year, and can develop up to 21 years and 2.31 million tons of CCER in the entire life cycle.It can be expected that under the guidance of the "30·60" carbon development goals, the new energy industry represented by the photovoltaic industry will occupy a more important position in my country's energy structure. In order to accelerate the advancement of my country's "14th Five-Year Plan" and even longer Provide strong support for high-quality energy development. (Xie Wenchuan and Wu Mengyao)
