The Pace Of Green Energy Transformation Is Accelerating
In 2023, my country's energy green and low-carbon transformation will accelerate, and renewable energy will maintain a good trend of high-speed development, high proportion of utilization, and high-quality consumption. At the same time, new energy storage installed capacity is rising rapidly and new technologies are emerging, strongly supporting the construction of new power systems; the construction of a multi-level power market is progressing in an orderly manner, and the level of new energy consumption has been effectively improved.
The competitive advantages of wind power and photovoltaics are highlighted
The coastal city of Taizhou in Zhejiang Province has abundant wind energy. In 2023, the Yuhuan No. 2 offshore wind farm, the largest offshore wind farm in eastern Zhejiang, officially started construction. Chen Yiming, special responsibility administrator of the Development Department of State Grid Zhejiang Taizhou Power Supply Company, said that the wind farm will become the world's first 220-kilovolt flexible low-frequency technology transmission offshore wind farm, effectively improving the transmission capacity, transmission distance and transmission efficiency of the transmission line. In 2023, my country's total renewable energy installed capacity will continuously exceed the 1.3 billion kilowatt and 1.4 billion kilowatt marks during the year, reaching 1.45 billion kilowatts, accounting for more than 50% of the country's total installed power generation capacity, historically exceeding the thermal power installed capacity. The annual new installed capacity of wind power and photovoltaics has doubled, accounting for nearly 60% of the global annual newly installed capacity. The international competitive advantages of the wind power and photovoltaic industry have been further highlighted. In 2023, the output of key components such as wind turbines will account for more than 70% of the global market, and the output of photovoltaic polysilicon, silicon wafers, cells and modules will account for more than 80% of the global market.
Driven by technological innovation, in 2023, the world's first 16-megawatt offshore wind turbine independently developed by my country was successfully connected to the grid to generate electricity. The country's first deep-sea floating wind power platform with an offshore depth of more than 100 kilometers and a water depth of more than 100 meters, "CNOOC Guanlan" "" was successfully put into operation, and a number of leading demonstration projects such as Sinopec's Xinjiang Kuqa photovoltaic large-scale hydrogen production and Three Gorges Group's Kubuqi Desert photovoltaic desertification control were completed and put into operation.
Li Chuangjun, director of the New and Renewable Energy Department of the National Energy Administration, said that my country's renewable energy will maintain rapid development in 2023 and play a role in ensuring power supply, promoting energy transformation, expanding effective investment, increasing foreign trade exports, and reducing the cost of electricity for the whole society. important role.
New energy storage becomes key
New energy has the characteristics of intermittency, volatility, and randomness. To achieve a high proportion of grid connection, the power system regulation capability must be improved, and the development of new energy storage has become a key starting point. Data from the National Energy Administration shows that as of the end of 2023, the cumulative installed capacity of new energy storage projects that have been completed and put into operation across the country has reached 31.39 million kilowatts/66.87 million kilowatt hours, with an average energy storage time of 2.1 hours. The newly installed capacity in 2023 will be approximately 22.6 million kilowatts/48.7 million kilowatt-hours, an increase of more than 260% compared with the end of 2022.
Bian Guangqi, deputy director of the Energy Conservation and Science and Technology Equipment Department of the National Energy Administration, said that new energy storage is becoming a key technology for building new energy systems and new power systems, an important direction for cultivating emerging industries, and promoting the green and low-carbon transformation of energy production and consumption. important starting point. Since the "14th Five-Year Plan", new new energy storage installed capacity has directly promoted economic investment of more than 100 billion yuan. While the scale is growing, new energy storage technology routes are blooming. Since last year, construction has started on multiple 300-megawatt compressed air energy storage projects, 100-megawatt flow battery energy storage projects, and megawatt-level flywheel energy storage projects. New technologies such as gravity energy storage, liquid air energy storage, and carbon dioxide energy storage have been launched. The implementation of technology has shown an overall diversified development trend. The construction of new energy storage has effectively promoted the development and consumption of new energy. In recent years, new energy power generation in Anhui Province has gradually accounted for “half” of the electricity supply. Zhu Binbin, director of the Power Dispatching and Control Center of the State Grid Huaibei Power Supply Company, said: "The energy storage power stations in the Huaibei region have a grid-connected installed capacity of 161,600 kilowatts. During the Mid-Autumn Festival and National Day holiday last year, the energy storage power stations in the Huaibei region participated in a total of 41 times of regional power grid peak shaving, absorbing The amount of new energy power is 3.1168 million kilowatt hours, which plays an important role in the consumption of new energy power during critical periods." Bian Guangqi said that in the next step, the National Energy Administration will carry out research on relevant measures to promote the dispatch and application of new energy storage and guide the science of new energy storage Call to further play the role of system support and regulation.
The electricity market mechanism continues to improve
At present, new energy has entered a stage of large-scale, high-quality development. It is urgent to promote the green transformation of energy and power production methods through market mechanism innovation, promote the formation of a green and low-carbon lifestyle, and help achieve the "double carbon" goal. Our country is actively promoting the construction of a national unified electricity market system, and market-based trading of electricity continues to increase. Liu Gang, deputy director of the Market Supervision Department of the National Energy Administration, said that last year, the national electricity market traded 5.7 trillion kilowatt-hours of electricity, a year-on-year increase of 7.9%, accounting for 61.4% of the total social electricity consumption, an increase of 0.6 percentage points from the previous year. "The market-oriented reform of electricity continues to deepen, and the proportion of market-based traded electricity has increased from less than 17% in 2016 to more than 61% in 2023. The market mechanism has played a decisive role in resource allocation." Liu Gang said. It is worth noting that medium- and long-term electricity transactions have been operating regularly across the country, accounting for more than 90% of market-based electricity, giving full play to the role of "ballast stone" and stabilizing the overall market size and transaction prices. The inter-provincial and inter-regional mid- and long-term markets operate smoothly, and the inter-provincial spot market adjusts excess and shortfalls, playing a positive role in optimizing the allocation of large-scale power resources. During the critical period of ensuring power supply during peak summer and winter, the inter-provincial and cross-regional market-based trading mechanism played a positive role in inter-provincial power support and mutual assistance to ensure supply. The power auxiliary service mechanism has tapped the system adjustment capacity of more than 117 million kilowatts throughout the year, and promoted an average annual increase in clean energy power generation of more than 120 billion kilowatt hours.
