The energy industry is both the "ballast stone" of the national economy and the livelihood security, and the "main battlefield" for advancing the realization of the carbon peak carbon neutralization goal. In recent years, China's new energy industry has developed rapidly, the new energy system and the new power system have been continuously constructed, and the energy low-carbon green transformation has been vigorously promoted.

Recently, the National Energy Administration issued the "Key Points of Targeted Assistance and Support Work in 2024", indicating that the development of clean energy should be accelerated, the construction of wind power and distributed photovoltaic power should be promoted, infrastructure for energy supply security should be strengthened, and the shortcomings of energy use should be made up.

In the global proposition of carbon peaking and carbon neutrality, China's photovoltaic power generation industry has become increasingly mature, and the industry has great development potential. State Grid Shuyang Power Supply Company helps build "zero-carbon factories" and "green enterprises", providing strategic guarantees for local rooftop distributed photovoltaic projects. The daily average power generation exceeds 90,000 kWh, which can provide 1068.75 million kWh of clean energy electricity annually and reduce energy consumption costs by 40%; State Grid Jinchang Power Supply Company explores the new model of "photovoltaic + factory buildings", and builds photovoltaic panels on the roofs of enterprise plants according to local conditions. The annual average power generation is expected to be 8.4 million kWh, which is equivalent to reducing carbon dioxide emissions by nearly 6,500 tons......

According to data from the China Photovoltaic Industry Association, in 2023, the scale of China's photovoltaic industry continued to expand, with a newly installed capacity of 216.88 GW, a year-on-year increase of 148.1%. The output of major manufacturing segments such as polysilicon, wafers, cells, and components increased by more than 64% year-on-year, with the total industry output value exceeding 1.75 trillion yuan.

"Adequate market competition, supporting advantages with complete industrial categories, and policy support and guidance have forged a complete industrial chain for China's photovoltaic industry." Wang Shijiang, secretary-general of the China Photovoltaic Industry Association, said that from the perspective of a longer industry cycle, how to ensure the green power needs of enterprises while taking into account the stability of the power grid needs further exploration.

Timely overhaul and troubleshooting of power transmission lines is crucial to ensuring the stability of a power system. In order to ensure the safe and stable operation of the power grid, Gansu Power Grid Corporation utilizes an "integrated" operation and maintenance model on this line, using intelligent technologies such as drone patrolling, laser foreign object removal, and online monitoring systems for the power transmission lines. With these technologies, the company can quickly issue early warnings and eliminate potential hazards in the power transmission lines.

High-level safety in new energy systems is reflected not only in the stability of power transmission lines, but also in assuring the supply and consumption of energy. Among these, the multi-energy complementary model provides a solution to the problem of "new energy is clean but not stable." In eastern Gansu, the Longdong Integrated Renewable Energy Project led by the State Grid Qingyang Power Supply Company is exploring a new model of "wind and solar power in the same field and wind turbines in mixed rows". First, the complementarity of wind and solar energy is achieved. Then, multiple forms of energy storage are configured synchronously according to the installed capacity. The world's largest wind-solar project will be built, which is expected to generate an average of 2.271 billion kilowatt-hours of green electricity per year.

The intrinsic requirement of the new energy system is to build a new energy system with storage as the core and multi-energy complementation. Zeng Shaojun, the secretary-general of the New Energy Chamber of Commerce of the All-China Federation of Industry and Commerce, said that without the support of new energy storage technology, no single new energy source can independently undertake the heavy responsibility of the new energy revolution. Both centralized and distributed energy storage should be promoted. We should actively develop the integration of source, network, load, storage and control, and promote multi-energy complementation.

Security of supply and consumption are the two main lines of energy low-carbon transformation, and stable, safe, and reliable UHV transmission and transformation lines are important carriers of the new energy supply and consumption system. Recently, State Grid Gansu UHV Company will replace the phase-shifting transformer rotor components for the Qilian converter station of the "Qi-Shao UHV" line, and complete a "comprehensive physical examination" of the line before the peak electricity consumption arrives. This upgrade will help the stable consumption of new energy electricity and further improve the resource optimization and allocation capabilities of the Gansu power grid.

In addition to new energy industries such as wind power and photovoltaic power, traditional fossil energy represented by coal is still an important guarantee for China's energy security. In recent years, the State Grid Neijiang Power Supply Company has accelerated the "coal-to-electricity" alternative promotion project, providing technical guidance throughout the process, saving more than 3.7 million yuan per year in energy costs such as refractory materials, denitration, desulfurization, and dust removal. It effectively reduces the consumption of fossil energy and reduces emissions of sulfide, nitrogen oxides and dust.

"The energy structure rich in coal, poor in oil, and little in gas and the large amount of energy consumption are China's basic national conditions. This determines that we must establish first and then break it down, and first ensure energy security and stability." The relevant person in charge of the National Energy Administration said that we must seize the "bull nose" of adjusting the energy structure, accelerate the construction of a clean, low-carbon, safe and efficient energy system, and use profound changes in the energy industry to help the comprehensive green transformation of economic and social development.
