The first Corrosion Control Engineering Conference will be held in late June

On March 28th, the first Corrosion Control Engineering Conference and the press conference for the publication and distribution of “Modern Corrosion Science – Corrosion Control Template” were held in Beijing. The reporter learned from the meeting that the first Corrosion Control Engineering Conference will be held in Xi’an in late June 2025.
Wang Hao, Secretary General of the China Corrosion Control Technology Association and International Secretary of the ISO International Corrosion Control Engineering Life Cycle Standardization Committee, introduced that the first Corrosion Control Engineering Conference was hosted by the China Corrosion Control Technology Association with the theme of “Corrosion and Life”. It was a conference to improve the major positioning of corrosion and corrosion control and explore the relationship between corrosion and life. The conference aims to promote standardization and innovative development in the field of corrosion control engineering, fully implement the construction of a new era of “fundamentally comprehensive control of corrosion control engineering”, assist in the coordinated promotion of the country’s “dual” construction and “two new” work, and promote high-quality development in the field of corrosion control engineering.
Corrosion is a great engineering project with extremely special characteristics. Ren Zhenduo, former president of the China Corrosion Control Technology Association and recipient of the highest achievement award in the corrosion control industry, pointed out at the meeting that corrosion is the process in which the natural interaction between anything in nature and the corresponding environment causes varying degrees of changes in its original performance. This process of change is spontaneous, covert, gradual, sustained, non-linear, complex, and cumulative, which can cause catastrophic damage to human society, and even lead to major accidents such as the shocking Fukushima nuclear accident in Japan and the oil pipeline leak and explosion in China on November 22. It is completely different from the visible and tangible engineering that is formed through the natural, artificial, or composite integration of many related factors.
In February of this year, the book “Modern Corrosion: Corrosion Control Template” was officially published and distributed by Science Press. Gu Xiulian, the Vice Chairman of the Tenth National People’s Congress, the former Minister of Chemical Industry, Li Yongwu, the former Vice Minister of Chemical Industry and the former Director of the State Petroleum and Chemical Industry Bureau, and other leaders served as advisers and prefaced the book. Ren Zhenduo serves as the editor in chief. Wang Hao pointed out that the publication and distribution of this book is a milestone event in the field of corrosion and corrosion control in China and even internationally. We should recognize that corrosion cannot be eliminated, but it can be controlled. Fundamentally, comprehensively and effectively controlling corrosion has become an extremely important international issue that humanity urgently needs to solve
This book scientifically reveals the essence, characteristics, and properties of corrosion through in-depth analysis, research, summarization, and improvement of work processes; The process of corrosion formation and the harm it causes to the corroded object (including its lifespan) are vividly explained using typical cases. At the same time, this book proposes scientific and technological measures and countermeasures for corresponding corrosion, from passive resistance to active control. It adopts a systematic prevention and treatment plan supported by big data, new material applications, and intelligent means, and presents it to readers in the form of a corrosion control template.
It is worth mentioning that this book creatively proposes the concept of “corrosion control template”. By comprehensively and accurately implementing corrosion control templates, and synchronously designing, constructing, operating, and supervising them with the main project, it is possible to achieve effective control, ineffective alarms, and achieve the best benefits, truly reducing, avoiding, or eliminating the occurrence of major safety and environmental accidents, and safeguarding the high-quality development of various industries and the whole society.

Collaboration between government and enterprises to launch a tough battle for expanding the carbon market

With the official introduction of the “Plan”, the three high emission industries of steel, cement, and aluminum smelting have entered the countdown to the national carbon market. To ensure a smooth transition and effective emission reduction, the Ministry of Ecology and Environment will focus on three major directions: task implementation, capacity building, and policy guidance.
The relevant person in charge of the Ministry of Ecology and Environment stated that in order to effectively implement the requirements of the Plan and prevent potential risks and hidden dangers that may arise from the inclusion of new industries in the carbon emission trading market management, the next step will be to ensure the smooth inclusion of the three industries in the carbon emission trading market through the following measures.
Firstly, accelerate the implementation of various work tasks. Clarify the tasks and completion deadlines for the establishment of a list of key emission units, monthly certification of key parameters, verification of carbon emission reports, issuance of approved quotas, and clearance of quotas. Distribute and implement the annual quota total and allocation plan, and establish a new industry quota allocation system.
Secondly, strengthen the capacity building of newly included enterprises. Develop a special action plan for capacity building and provide targeted thematic training for enterprises, local ecological environment departments, and technical service institutions. Organize multiple rounds of supervision and assistance, develop a key manual for carbon emission management, provide targeted guidance to enterprises, and enhance their carbon emission accounting capabilities and carbon asset management levels.
Finally, strengthen policy interpretation and publicity guidance. Strengthen information disclosure, promote timely disclosure of emission, performance, trading, pledge and other related information by relevant entities in accordance with laws and regulations, and accept public and social supervision.
Next, the Federation will play an active role in policy promotion, organizational coordination, operational tracking and research, capacity building, and promotion and application of green and low-carbon technologies to promote the effective implementation of the Plan, “said the relevant person in charge of the China Building Materials Federation.
As a representative enterprise in the cement industry, Jiang Yusheng stated that Jidong Cement firmly supports and actively responds to the important decision of the cement industry to be included in the national carbon market. Taking this as an opportunity, it will integrate the low-carbon development awareness of “carbon emission has costs, carbon reduction has benefits” into the entire production and operation process, carry out six aspects of work including source carbon control, process carbon reduction, energy consumption carbon reduction, technology carbon reduction, end carbon reduction, and fine carbon management, and continuously polish the green and high-quality development background.
What challenges will companies in three industries face after being included in the carbon emissions trading market? How to deal with it?
Wang Haibing believes that the first challenge is data. For related enterprises, there may be issues such as poor accuracy of self-reported data and discrepancies with data collected from designated monitoring stations. Next is the management challenge. For some enterprises with surplus quotas, due to their small scale and limited profits from market transactions, they may not actively engage in quota management; For some enterprises with a shortage of quotas, due to the large amount of quota clearance but the small amount of punishment, they may choose to passively replace quota management with the “penalty payment” method.
In addition, there are also issues such as increased operating costs, lack of financial support for emission reduction technology innovation, and leakage of commercial secrets, “said Wang Haibing.
In this regard, Wang Haibing suggests that enterprises should fully recognize the significant importance of achieving the national strategy of “dual carbon” goals subjectively, deeply integrate enterprise value creation activities into the national strategy, and enhance social and moral responsibilities while fulfilling economic and legal responsibilities. At the same time, it is necessary to actively establish communication and coordination mechanisms with government departments, industry associations, and industry alliances, grasp relevant rules as soon as possible, strengthen the construction of one’s own capacity system through systematic training, multi-party exchanges, practical exploration, and other methods, and improve the level of carbon emission accounting, carbon asset management, and other aspects. In addition, targeted measures such as forming innovation consortia, establishing procurement alliances, and sharing or even reducing low-carbon technology innovation risks and application costs through quota exchange technology can be taken.

Clear roadmap from smooth transition to deep emission reduction

The Plan specifies that units in the steel, cement, and aluminum smelting industries with annual greenhouse gas emissions reaching 26000 tons of carbon dioxide equivalent will be identified as key emission units and included in the management of the national carbon emission trading market. 2024 will be the first control year for the steel, cement, and aluminum smelting industries, and the first performance work will be completed by the end of 2025.
The relevant person in charge of the Ministry of Ecology and Environment said that they will continue to adopt the idea of quota allocation based on carbon emission intensity control for the three industries that are of great concern.
Among them, in 2024, the quota amount obtained by steel, cement, and aluminum smelting enterprises is equal to the verified actual emissions, and all enterprises have no quota gap and do not need to pay performance costs. In 2025 and 2026, the overall profit and loss balance of quotas in various industries will be achieved. The upper and lower limits of adjustment coefficients will be set based on carbon emission intensity performance, and the quota surplus and deficit rates of all enterprises will be controlled within a small range, without causing shrinkage effects on the development of industry enterprises. After 2027, we will study and establish a clear and transparent industry quota total, gradually and moderately tighten it, and promote the continuous reduction of carbon emission intensity in three industries.
This means that companies will not face explicit carbon costs in the first year of compliance, and will not need to pay additional compliance costs. This allocation method helps to smooth the transition, familiarize companies with the rules and operating mechanisms of the carbon market, and avoid causing excessive impact on the industry. At the same time, it lays the foundation for gradually tightening quotas and promoting corporate emissions reduction in the future. “The relevant person in charge of the Ministry of Ecology and Environment stated that 2025 will also become a key transformation node for the steel, cement, and aluminum smelting industries – the number of quotas obtained by enterprises in each industry in 2025 and 2026 will be linked to production capacity output, and the quota surplus and deficit rate will be reasonably determined. If the carbon emission intensity of a company is lower than the set baseline, it may obtain additional quota surplus; On the contrary, if the carbon emission intensity is higher than the baseline, there may be a shortage of quotas and additional compliance costs may need to be paid.
According to the deployment plan, the Ministry of Ecology and Environment will steadily and orderly promote relevant work in two stages based on the work concept of “implementing while improving”. The relevant person in charge of the Ministry of Ecology and Environment revealed that the Ministry will soon issue a notice on the inclusion of three industries in the management of the carbon emission trading market, clarifying the tasks and completion deadlines for the establishment of a list of key emission units, monthly certification of key parameters, verification of carbon emission reports, issuance of approved quotas, and clearance of quotas.
Specifically for the cement industry, the ‘Plan’ specifies that cement enterprises included in the national carbon emission trading market only control direct emissions from fossil fuel combustion and industrial processes. Considering the alignment with international carbon market rules, to avoid duplication with the power generation industry, regardless of indirect emissions from electricity and heat consumption, only carbon dioxide is explicitly controlled. The Plan specifies that key emission units with annual direct greenhouse gas emissions reaching 26000 tons of carbon dioxide equivalent must be included in the management of the national carbon emission trading market, which means that the vast majority of cement clinker production enterprises need to be included. For cement enterprises included in the directory management, the provincial ecological environment authorities will allocate quotas to key emission units within their administrative regions based on the total annual carbon emission quota and allocation plan.
It is reported that as of now, the Ministry of Ecology and Environment has upgraded and transformed the functions of the management platform, registration system, and trading system. Since the end of February, more than 900 enterprises in the steel, cement, and aluminum smelting industries have been organized to conduct relevant platform function tests to help enterprises familiarize themselves with market rules and further improve system functions.

03 Offshore wind power ship industry chain accelerates to adapt to new industry trends

Currently, the global offshore wind power industry is undergoing profound changes from nearshore to deep offshore, from fixed to floating, and from scale to intelligence. At the same time, the offshore wind power ship industry chain is accelerating its upgrading towards large-scale, intelligent, and green development. The research and innovation of core equipment such as wind power installation ships, cable laying ships, and operation and maintenance mother ships has become the focus of the industry. Tan Naifen, Deputy Secretary General of the China Shipbuilding Industry Association, said that the shipbuilding industry, as an important support for the offshore wind power industry, is adapting to the development needs of offshore wind power and continuously upgrading. The deep-sea region is a strategic emerging industry that deeply integrates wind power technology and ocean engineering technology, with enormous potential, “said Tan Naifen.

 

Xia Houmingsheng, a senior engineer at the 708th Research Institute of China Shipbuilding Industry Corporation, said that offshore wind power projects involve multiple types of ship types, which can be divided into three categories according to their functions: in the early stage of wind farm construction, measurement ships, exploration/platform ships, and other ship types are required; During the construction period of the wind farm, it is necessary to use crane ships for pile foundation construction, wind turbine equipment hoisting ships, and cable laying ships; After the construction of the wind farm is completed, offshore wind farm operation and maintenance ships such as heavy-duty maintenance ships and personnel transport ships are required.
Qidong Zhongyuan Shipping Marine Engineering is a professional enterprise engaged in the design and manufacturing of marine engineering equipment under Zhongyuan Shipping Heavy Industry. Wan Jiaping, Technical Director of Offshore Engineering and Director of Offshore and New Energy R&D Center at Qidong Zhongyuan Shipping, used offshore wind power installation ships as an example to introduce the continuous evolution path of the shipbuilding industry to adapt to the development of offshore wind power. Wan Jiaping told China Industry News that the early installation ship technology was outdated and could not meet the needs of large-scale offshore wind power development, and the industrial development was in its infancy. Before 2010, China’s offshore wind power installation ships relied on imported equipment from Europe, with separate installation being the main method, resulting in low efficiency and high costs, which hindered the development of the industry. After 2020, CCCC Third Harbor Engineering Co., Ltd. developed a 5000 kilojoule hydraulic pile hammer (the world’s largest single acting equipment), which increased its lifespan by 30% and broke the foreign technology monopoly. The popularization of self elevating installation ships can adapt to the typhoon environment along the southeast coast of China, improve installation efficiency and safety, and promote the development of offshore wind power industry. Nowadays, there is continuous technological innovation in domestic installation ships, such as the development of new lifting equipment and the application of intelligent control systems, which improve the performance and efficiency of installation ships. In the future, with the development of offshore wind power towards deep and distant seas, it is necessary to promote the upgrading of installation ships towards large-scale and multi-functional directions to meet the diversified needs of offshore wind power projects and enhance industrial competitiveness.
By 2025, the proportion of global deep-sea projects will exceed 40%, requiring larger tonnage ships to support 15MW units and promote the development of installation ships towards large-scale and high-performance. The development of deep-sea projects is difficult, requiring high technical and performance requirements for installation ships, providing power for technological innovation and upgrading in the installation ship industry. Wan Jiaping further explained that installation ships need to adapt to 8-18MW wind turbines and have deck loads exceeding 10000 tons to improve installation efficiency and safety. In terms of multifunctionality and high performance, it is necessary to integrate pile driving, operation and maintenance, energy storage and other functions, support “wind power+” projects, expand the application scenarios of installation ships, and enhance industrial added value.
From installation to cable laying to operation and maintenance, the offshore wind power ship industry chain is accelerating its evolution, providing support for offshore wind power to move towards deep and distant seas. Xiahou Mingsheng believes that when designing various types of ships, efforts should be made from four aspects to adapt to the trend of offshore wind power developing towards deep and distant seas: first, to meet the ultra large size of deep and distant sea operations; second, to be multifunctional in various application scenarios; third, to be green and low-carbon under energy-saving and environmental protection requirements; fourth, to be intelligent in ship and operation systems.
The development of offshore wind power towards deep and distant seas has led to increased complexity in wind turbine capacity, higher failure rates, and increased maintenance costs, requiring more efficient operation and maintenance. To balance operation and maintenance costs with wind farm availability, China Ocean Engineering Equipment Technology Development Co., Ltd. (hereinafter referred to as “China Ocean Engineering”) has provided a new solution. Chen Jieyu, an expert in China’s offshore engineering control system, said that the wave compensation wharf and dynamic positioning control system launched by China’s offshore engineering help wind power ships accurately maintain their position in harsh environments, stabilize docking operations, and improve the safety of personnel and equipment transportation.
Liu Bochen, a researcher at the Federal Reserve Securities Research Institute, told China Industry News that in the context of the development of offshore wind power towards deep sea and large-scale, the industry and upstream and downstream enterprises in the industrial chain should make efforts to achieve high-quality development from three aspects: first, to improve technological reserves, focusing on breakthroughs in technologies such as 16MW and above wind turbines, floating foundations, and dynamic submarine cables; The second is to reduce costs through industrial chain collaboration and build a “common chain ecology”, such as Yangjiang Wind Power City achieving localized production of tower tubes and blades, reducing costs by 20%; The third is ecological compatibility design, which involves pre planning the integration of “wind power+pasture” projects to avoid conflicts over sea use.

02 Offshore wind power is entering the deep sea and moving towards large-scale development

The International Energy Agency (IEA) predicts in its “2024 Renewable Energy Report – Analysis and Forecast to 2030” that the cumulative installed capacity of offshore wind power is expected to reach 212GW between 2024 and 2030, and the global offshore new installed capacity is expected to increase to 45GW by 2030. With the gradual saturation of onshore wind power and nearshore offshore wind power development, the development of deep sea areas with water depths exceeding 50 meters or even 100 meters has become an inevitable choice and is expected to become the “golden race track” in the deep-sea economy. According to data from the World Bank (WB), there are over 71 billion kilowatts of offshore wind energy resources available worldwide, with deep-sea wind accounting for over 70%. However, the current utilization rate of these resources is less than 0.5%.
Li Hongtao, Deputy Director of the Ocean Engineering Technology Center of China Classification Society, said that China’s deep-sea potential development area has reached 670000 square kilometers and is rich in resources. The deep-sea wind speed is more stable, with an annual average wind speed of over 9 meters per second, and the power generation hours are significantly higher than those in offshore areas, making it suitable for large-scale wind power development. To adapt to the characteristics of the deep sea, large-scale and floating wind turbines are the major trends in the development of offshore wind power in countries around the world.

 

In 2024, the average single unit capacity of offshore wind turbines in China will be 10MW. As of now, 16MW has been widely used, 18-20MW prototypes have been installed and connected to the grid for power generation, 26MW prototypes have been taken offline, and only 15MW prototypes are currently in operation in other countries, “Tian Ye told China Industry News.” China’s large-scale wind turbines have taken the lead in the world. Wind turbines have achieved large-scale, platform based, intelligent, and modular development, with technology types including doubly fed, direct drive, and semi direct drive.
Goldwind Technology (002202. SZ/02208. HK) is one of the earliest enterprises in China to enter the field of wind power equipment manufacturing. Recently, the company released its 2024 annual report, which showed that it achieved a revenue of RMB 56.699 billion that year, a year-on-year increase of 12.37%; The net profit attributable to the parent company was RMB 1.86 billion, a year-on-year increase of 39.78%. The simultaneous growth of the company’s operating revenue and profit indicates that Goldwind Technology is entering a virtuous growth cycle. The company’s annual report mentions that for future deep sea application scenarios, the company has launched a new generation of deep sea flagship product GWH300-20 (25) MW model. It is reported that this model can reduce the levelized cost of electricity (LCOE) of wind farms by up to 10% in future deep sea scenarios. In response to the layout of the Far East Sea, the annual report also emphasizes that Goldwind Technology continues to carry out research and development on floating products and technologies. In 2024, the company will release a new floating mooring system. It is reported that Goldwind Technology’s floating wind turbine floating body aims to deploy wind power generation equipment in deep waters far from the coastline, in order to fully utilize the abundant marine wind energy resources.
The relevant person in charge of Goldwind Technology told China Industry News that the company’s wind turbine manufacturing is simultaneously focusing on deep-sea and large-scale development. In terms of large-scale wind turbines, by launching the new generation of flagship products GWH300-20 (25) MW, we will continue to research and optimize large-scale unit technology to consolidate our development advantages; In terms of the development of deep-sea wind power, we actively carry out technological innovation and project practice, enhance our wind power development capabilities in the deep-sea environment, and seize the opportunity of deep-sea wind power.
Wen Shugang, Secretary of the Party Group and Chairman of China Huaneng Group (hereinafter referred to as “China Huaneng”) Co., Ltd., wrote an article pointing out that China Huaneng actively lays out offshore wind power clusters, with a cumulative approved, started, and put into operation of over 14 million kilowatts, firmly ranking first in the industry. China Huaneng is accelerating the cultivation of “new driving forces” in scientific and technological innovation, tackling and breaking through a number of “major national heavy equipment” and key core technologies such as the world’s largest 18 MW offshore wind turbine and deep-sea floating offshore photovoltaic power generation.
Li Hongtao said that floating wind power is the only way for offshore wind resource development to go deep into the sea. Floating wind power, due to its unique floating design, breaks through the water depth limit (>60 meters) and is suitable for complex geological sea areas. It can expand the scope of wind power development and develop broader sea resources. During the 25th China International Petroleum and Petrochemical Technology and Equipment Exhibition, China Industry News further learned about China’s first deep-sea floating wind power platform, the Haiyou Guanlan. It is reported that the “Haiyou Guanlan” independently developed and built by China National Offshore Oil Corporation (CNOOC) is China’s first floating wind power platform with a working sea area more than 100 kilometers away from the coastline and a water depth of over 100 meters. Its completion and operation have increased China’s independent development capability of offshore wind power from less than 50 meters to over 100 meters, laying a solid foundation for China’s wind power development from shallow waters to deep seas.
Li Hongtao said that the global floating wind power industry is in a rapid development stage, and as of 2024, the cumulative installed capacity of floating wind power worldwide has exceeded 1GW. It is expected that from 2022 to 2031, the global installed capacity of floating wind power will increase by 28.7GW, of which 90% will be concentrated after 2027 and will experience explosive growth in the coming years. It is expected that the global installed capacity of floating wind power will rapidly increase in the next decade, reaching 3.8GW in 2030 and 8.3GW in 2033. The development prospects of floating wind power in China are broad, with an expected increase in installed capacity of 500MW by 2030 and 1.0GW by 2033; China will move from following and running to a leading position.
China is currently in the stage of transitioning from engineering prototype demonstration to commercialization, “said Li Hongtao. China has completed the demonstration of five floating wind power prototypes, with a total installed capacity of about 40MW and a single unit cost of about 300-500 million yuan. The total planned installed capacity of Hainan Wanning floating wind farm is 1000MW (200MW in Phase I and 800MW in Phase II), marking the transition of China’s floating wind power from prototype demonstration to large-scale commercial development.

Less than 0.5% development, Far East Sea will become the “main battlefield” for offshore wind power

Less than 0.5% development, Far East Sea will become the “main battlefield” for offshore wind power
In the future, the Far East Sea will become the ‘main battlefield’ of the offshore wind power industry. “China Industry News learned at the” Offshore Wind Power Equipment Industry Chain Development Forum “that with technological progress and cost reduction, the proportion of offshore wind power in the global energy structure will continue to increase. The far-reaching offshore wind power project will become a key direction for future development, promoting the expansion of offshore wind power into broader sea areas.

 

According to data from the World Bank (WB), there are over 71 billion kilowatts of offshore wind energy resources available worldwide, with deep-sea wind accounting for over 70%. However, the current utilization rate of these resources is less than 0.5%. Tian Ye, Deputy Secretary General of the Wind Energy Professional Committee of the China Renewable Energy Society, said that with the profound development trend of offshore wind power, the global trend of large-scale offshore wind turbines is evident and is moving towards more than 20MW. Tan Naifen, Deputy Secretary General of the China Shipbuilding Industry Association, believes that as an important support for the development of offshore wind power and to adapt to the new development trend of offshore wind power, the shipbuilding industry chain is accelerating its upgrading towards large-scale, intelligent, and green development.
For 7 consecutive years, China has been ranked first in the world and continues to lead the development of offshore wind power
China drives the development of global offshore wind power, “said Tian Ye, Deputy Secretary General of the Wind Energy Professional Committee of the China Renewable Energy Society, at the” Offshore Wind Power Equipment Industry Chain Development Forum. Based on the annual lifting statistics of the Wind Energy Professional Committee of the China Renewable Energy Society and data from GWEC (Global Wind Energy Council), in 2024, China’s offshore wind power added over 4GW of grid connected installed capacity, accounting for more than 50% of the global market share and ranking first in the world for the seventh consecutive year. As of the end of 2024, China’s offshore wind power has accumulated 43GW of grid connected installed capacity, accounting for 51.3% of the global market share, ranking first in the world for the fourth consecutive year and continuing to lead the development of global offshore wind power.
From a corporate perspective, China has 7 out of the top 10 offshore wind turbine manufacturers in the world. According to GWEC data, in 2023, a total of 12 wind turbine manufacturers worldwide installed 1120 Taiwan Strait wind turbines, with a scale of nearly 11 GW. Among the top 10 companies, there are 7 Chinese enterprises including Mingyang Intelligent, Goldwind Technology, CSSC Haizhuang, and Dongfang Electric, with a total market share of about 67%. By the end of 2023, the cumulative installed capacity of offshore wind power worldwide has reached 76GW, with 6 Chinese companies among the top 10, and a total market share of approximately 48.6%.
In terms of offshore wind power, by 2024, 60% of the global offshore wind turbine production capacity will come from China, “said Tian Ye. Currently, China has become the world’s largest wind power production base, not only possessing the world’s leading wind turbine manufacturing base, but also the center of the largest key components. Currently, there are 153 wind turbine production bases in operation worldwide, with 74 more under construction or in the planning stage. Among them, there are only over 100 operating companies in China, and another 64 are under construction.
By 2030, the offshore wind power industry chain in the Asia Pacific region, except for China, will not meet local and regional construction needs. Tian Ye stated that from the perspective of future supply and demand, there will be a shortage of offshore wind turbines in the United States after 2025; Europe is the second largest wind turbine assembly and production base in the world, mainly located in Germany, Denmark, Spain, France, Portugal and Türkiye. Tianye said that in the future European market, it is expected that starting from 2028, the existing offshore wind turbines and installation ship capacity will not be sufficient to support the growth of offshore wind power installations outside of Europe; After 2029, Latin America will face bottlenecks.
Wan Jiaping, Technical Director of Offshore Engineering and Director of Offshore and New Energy R&D Center at Qidong Zhongyuan Shipping, said that by 2025, the cumulative installed capacity of offshore wind power worldwide will exceed 100 million kilowatts. China’s offshore wind power is developing rapidly, with continuously expanding installed capacity, becoming an important force in global offshore wind power. In Wan Jiaping’s view, policies are helping accelerate the development of the wind power industry. In 2016, the 13th Five Year Plan for Wind Power Development proposed a target of 5GW, and achieved 6.8GW ahead of schedule in 2019. During the 14th Five Year Plan period, relevant policies were introduced in various regions. In 2024, the country also issued the “Renewable Energy Electricity Price Additional Subsidy”. Under the guidance of multiple policies, a large number of offshore wind power projects were launched, and the installed capacity grew rapidly, entering a period of rapid development for the industry.

The continuous application of intelligent operation and maintenance system is expected to double the installed capacity

Smart station, ‘digital intelligence’ comes first. From traditional hydropower to new energy sources such as wind power and photovoltaics, intelligent operation and maintenance systems continue to be implemented in Hunan.

 

 

Wuling Power Remote Operation and Maintenance Center
The hydropower intelligent operation and maintenance system developed by Hunan Wuling Electric Power Technology Co., Ltd. for the first time in China, including five intelligent application modules of “remote inspection, equipment diagnosis, condition based maintenance support, optimized operation, and knowledge center”, was successfully included in the pilot demonstration project of “industrial Internet plus+safe production” of the Ministry of Industry and Information Technology in 2021 and the list of the first batch of “horse racing” innovation platforms during the “14th Five Year Plan”.
Wan Yuan, Secretary of the Party Committee and Chairman of Hunan Wuling Electric Power Technology Co., Ltd., introduced that the advantage of the intelligent operation and maintenance system for hydropower is that it can reduce on-site operation and maintenance personnel by remotely analyzing equipment conditions and setting inspections remotely. With the development of technology and the application of artificial intelligence, data models, and cloud computing technology, deep mining of operational data can be achieved to detect potential equipment hazards in advance.
The intelligent operation and maintenance system for hydropower has been promoted and applied in 19 hydropower stations in Hunan, Jiangxi, Chongqing, Qinghai, Guizhou, etc. More than 650 equipment hazards have been identified in advance, and special analysis reports have been issued to guide power plant maintenance. The annual comprehensive benefits are nearly 100 million yuan. By the end of this year, more hydropower stations will be connected, “said Wan Yuan.
The reporter learned that Hunan’s hydropower development presents three major characteristics:
Firstly, present the “three cross” (cross regional, cross basin, and cross scheduling) situation. Taking Wuling Electric Power as an example, its 13 hydropower plants are distributed in Hunan and Guizhou provinces, as well as the Yuan River, Zi River, and Xiang River basins, respectively belonging to the Central China Grid Dispatch and Hunan Provincial Dispatch.
Secondly, the hydropower plant implements a regional centralized control mode of “one person, one seat, multiple plants”, with one duty seat monitoring an average of 3-4 power plants. At present, the hydropower centralized control center controls 13 hydropower plants, 58 control units, and controls a capacity of 5.245 million kilowatts. “On the fourth floor of the Wuling Power Generation Centralized Control Center in Changsha, Hunan, Sha Yongbing, the director of the Wuling Power Generation Centralized Control Center, introduced to reporters.
Thirdly, hydropower plants will implement closed door operation at night. In remote control mode, each centralized power plant has achieved joint optimization scheduling for flood control and power generation. By utilizing the flood control and peak shifting functions of the reservoir group in the basin, the flood disasters in the tail of the Yuan River and the Dongting Lake area have been alleviated; Over the years, optimized scheduling has increased electricity production by 8.36 billion kilowatt hours, resulting in significant benefits for the comprehensive utilization of water resources.
We have achieved full supervision and control of the centralized hydropower plant, with over 20000 remote starts and stops per year, a success rate of 100%, and safe operation of the centralized control system for over 5000 days, “said Sha Yongbing.
It is worth mentioning that in addition to the two million level hydropower plants, Wuqiangxi Power Plant and Sanbanxi Power Plant, the Qiandong Thermal Power Plant located at the border of Hunan and Guizhou provinces has an installed capacity of up to 1.2 million kilowatts. It forms a power station group with the characteristics of “complementary water and fire, and mutual assistance between abundant and scarce” together with three hydropower plants in the upper reaches of the Yuan River, namely Sanbanxi, Baishi, and Tuokou. Through centralized control of water and fire joint scheduling, it provides stable and reliable electricity guarantee for Hunan.
In 2024, the installed capacity of wind and photovoltaic power in Hunan will reach 29.82 million kilowatts, surpassing traditional thermal power to become the largest installed body. New energy installation has become the largest power source in Hunan.
Similar to the intelligent operation and maintenance system for hydropower, the new energy remote operation and maintenance system can perform remote inspection, analysis, and risk assessment on new energy equipment such as wind power and photovoltaics.
The new energy intelligent operation and maintenance system is based on hydropower technology research and development. After successful application in hydropower, it is transplanted to the field of new energy, and its functions and modeling are expanded according to actual situations. After our station is equipped with the independently developed new energy intelligent operation and maintenance system, it can achieve centralized panoramic monitoring, intelligent warning, expert analysis, energy efficiency analysis, and equipment status evaluation of wind and photovoltaic assets. “said Wan Yuan.
It is reported that since its launch in June 2024, the system has been widely applied to 53 wind power and more than 10 photovoltaic stations. Through system warning, more than 300 defects in wind power equipment such as gearbox failure, bearing wear, and pitch bearing tooth breakage have been detected in advance, avoiding equipment failures and losses of about 5 million yuan; Through the application of drone inspection, image recognition, and infrared thermal imaging technology, nearly 10000 defects in various equipment such as photovoltaic modules and inverters were detected in advance, and approximately 12 million kilowatt hours of power generation losses were recovered.
The intelligent operation and maintenance system equips the power system with ‘smart eyes’ and’ smart brains’, reducing the workload of on-site personnel, ensuring safe and stable operation of equipment, improving energy efficiency, assisting in the construction of smart power stations, and promoting the development of new power systems. This year, the installed capacity of hydropower and new energy intelligent operation and maintenance systems is expected to double.
Located at the dual end of the national energy and power network, Hunan suffers from a shortage of coal, oil, and natural gas resources. Since the 14th Five Year Plan, Hunan’s power supply load has continuously reached new highs, with the highest power load reaching 41.65 million kilowatts in 2023. The peak valley load difference rate in Hunan is close to 60%, ranking first among State Grid.
At the same time, the support capacity of new energy for Hunan’s power system is still insufficient, with a lack of peak capacity. During the peak winter season, the output of wind and photovoltaic power generation is only about 5%, relying mainly on external power and local coal-fired power support. On the one hand, Hunan’s poor resource endowment has led to a long-term dependence on energy exports of over 80%; On the other hand, the proportion of basic support for thermal power generation in Hunan is relatively low, about 40%, which is about 9 percentage points lower than the national average.
In recent years, although the country has planned cross regional transmission channels, the difficulty for Hunan to obtain external power input has increased. The insufficient coal production capacity in Hunan is constrained by both high transportation costs and a shortage of transportation capacity, resulting in limited space for large-scale new coal-fired power projects. Amidst the interweaving of old and new issues and contradictions, the rapid development of wind and solar energy storage, as well as the accelerated construction of new energy smart stations, are expected to help Hunan solve the dilemma of electricity “gap”.

A “2-hour work circle” is now established for maintenance and inspection of areas with few personnel on duty in mountainous wind farms

From being stationed in the deep mountains to being on duty in the cloud, Lianyuan Longshan Wind Farm, as the first batch of pilot stations of State Power Investment Corporation Wuling Power Co., Ltd. (hereinafter referred to as “Wuling Power”), has taken the lead in promoting the construction of smart stations.

 

Lianyuan Longshan Wind Farm
In the central control room of Lianyuan Longshan Wind Farm, the reporter saw that two rows of computers were arranged in sequence for AGC monitoring, SVG monitoring, intelligent auxiliary control, wind turbine video monitoring, etc. Through scheduling instructions, local instructions, etc., the real-time active power, scheduling communication, and fan operation status of the wind turbine are displayed in real-time on the monitoring screens of each computer.
The total investment of Lianyuan Longshan Wind Farm is 420 million yuan, with a designed annual grid connected electricity of 105 million kilowatt hours and a utilization time of 2100 hours. At Lianyuan Longshan Wind Farm, we have implemented video surveillance to monitor the operation of wind turbines, booster stations, and equipment platforms in real time. Data from the wind farm can be transmitted to the Changsha Production and Operation Center for unified monitoring. If there is a fault warning, the Changsha Production and Operation Center will issue it to the regional maintenance center for analysis and processing. At the same time, through the intelligent transformation of the station, video surveillance, automatic fire protection, electronic fence alarm, etc. have been incorporated into the intelligent operation and maintenance system independently developed by Hunan Wuling Electric Power Technology Co., Ltd., achieving equipment environment control and defect warning, “said Zhu Cheng.
The reporter learned that the construction of high-altitude wind farms often faces difficulties such as road construction and large-scale transportation. The wind turbine towers are high and heavy, requiring high requirements for transportation vehicles. The scale of its construction also needs to be determined based on resource assessment, transportation capacity, and actual environment. In winter, ice and snow disasters are the focus of prevention and control, especially the icing on wind turbine blades often leads to wind turbine shutdown. When melting ice, if there are tourists or residents below, it can also cause personal injury.
We have four monitoring video probes installed on each wind turbine. Among them, there are three fixed ones inside the wind turbine that can be adjusted to fixed positions to monitor the main components. The external video probe of the wind turbine is a rotatable spherical probe, which is convenient for inspecting the equipment and facilities on the wind turbine platform. If it is not inspected on a daily basis, it will be fixed at the box transformer position on the outdoor platform to monitor the operation of the equipment. “Zhu Cheng said,” Previously, wind farm operation and maintenance required 4-5 people to take turns on duty. After the construction of the smart station, employees work and live in a centralized office at the mountain maintenance center, greatly improving the working and living environment and solving many inconveniences caused by harsh environments during winter duty, including water and power outages
The reporter learned that the technological transformation of new energy stations has reduced megawatt employment by about 38%, improved defect elimination speed, reduced equipment failure rate, and enhanced power generation efficiency. As the largest clean energy development and operation enterprise in Hunan Province, Wuling Electric Power will continue to promote the intelligent transformation of 12 new energy stations in Hunan Province this year.
Adhering to the concept of “intelligent transformation, safety assurance, and efficiency improvement”, we will build a modern intelligent operation system that is “2+N” (production and operation center+power trading center+N regional maintenance and inspection centers), intensive, standardized, specialized, digitalized, and refined. This will promote the formation of a new type of production relationship and cultivate new quality productivity. On December 20, 2023, State Power Investment Corporation will fully launch the construction of smart stations.
Compared to the traditional narrow definition of “one site, one station”, the smart stations of State Power Investment Corporation are a broad cluster of stations, which is a comprehensive construction of “centralized monitoring, regional maintenance, production and sales coordination, and few people (unmanned) on duty”. Through multi-level control of “production and operation center regional maintenance center smart station”, vertical connection from the production and operation center to various wind farms, photovoltaic power stations, and energy storage stations can be achieved.
The establishment of the maintenance and inspection center has achieved regional coordinated control, changing the previous single site single operation and maintenance mode to a clustered and intensive operation and maintenance mode, significantly reducing production costs and improving the efficiency of human resource utilization.
Li Xianming, Deputy Secretary of the Party Committee and General Manager of Wuling Electric Power New Energy Branch, introduced to reporters that “in Hunan, there are generally problems such as’ small, scattered, biased, and far ‘in new energy stations. The scale of the stations varies, with the smallest station having an installed capacity of 20000 kilowatts, while the larger ones have an installed capacity of 100000 kilowatts and 200000 kilowatts. The management method of the maintenance center is to integrate and manage the new energy stations. Taking the 25 wind turbines scattered in Lianyuan Longshan Wind Farm as an example, they were previously regarded as independent individuals. Now, these 25 wind turbines are regarded as a point, and these’ points’ of all stations together form a station cluster similar to a large factory, which is uniformly managed by the maintenance center
As of now, Wuling Power has built and put into operation four maintenance and inspection centers in Xiangzhong, Xiangnan, Zhongwei, and Yuxi, completed the intelligent transformation of 10 stations, created a “2-hour work circle” for new energy operation and maintenance, and promoted the implementation of station cluster management.
It is understood that the maintenance center mainly implements a centralized operation and control mode of “regional maintenance+station security”. In 2023, only 20 operation and maintenance personnel from the central Hunan region will enter the city, reducing the comprehensive labor cost by about 8 million yuan per year.

Accelerating the construction of Hunan’s new energy smart stations from “deep mountain garrison” to “cloud based duty”

The Longshan Mountain in Lianyuan, with an altitude of 1200 meters, is located at the border of Xiangxiang, Shaoyang, and Xinshao in Hunan Province. It is a remote mountainous area more than 50 kilometers away from the county seat. Here, the mountain road winds and bends rapidly, with dense forests on both sides of the road. Halfway up the mountain, 25 wind turbines are arranged in a row with the letters “several”, and the blades of the turbines rotate and make a rustling sound with the wind.
On March 25th, departing from Changsha City, Hunan Province, China Industry News reporters drove for 2.5 hours to visit a smart wind farm deep in the mountains of Lianyuan Longshan, known as the “southern medicine capital”.
Zhu Cheng, the operation and maintenance manager of the Xiangzhong Maintenance Center of Wuling Electric Power New Energy Branch, introduced to reporters that the Lianyuan Longshan Wind Farm started construction in 2017, achieved grid connected power generation in April 2018, and started intelligent transformation in January 2023, realizing a few person (unmanned) production management mode.
Previously, wind farm operation and maintenance personnel worked in harsh environments for a long time, relying mainly on regular vehicle supplies for material transportation. Even during heavy snow road closures, personnel had to shoulder materials and carry heavy loads to move forward.
Nowadays, at the maintenance and inspection center in central Hunan, dozens of kilometers away, duty personnel can remotely monitor and closely monitor the equipment status of seven stations, including Lianyuan Longshan Wind Farm, through digital display screens. Once the equipment issues an alarm, the operation and maintenance personnel can quickly conduct remote fault diagnosis and analysis, and the regional maintenance team can also arrive at the scene within 1 hour, greatly reducing the burden of on-site maintenance.
Remote centralized control, regional maintenance, and station security “promote the transformation of new energy production and operation models towards intensification, specialization, and digitization, becoming a microcosm of the construction of smart new energy stations in Hunan Province.

Intelligent technology empowers power station operation and maintenance

On the vast desert controlled by sandstorms, drones and intelligent cloud platforms serve as the “thousand mile eyes” and “windward ears” of the operation and maintenance team.
A drone carrying an infrared camera and a visible dual light camera takes off from the aircraft nest and is capable of precise path planning and heading control on the photovoltaic panel surface. It collects infrared and visible light images of photovoltaic modules in the air and performs image feedback and defect recognition.
The unmanned aerial vehicle image recognition algorithm independently developed by Chint Zhiwei can achieve precise detection and localization of various component defects such as strip-shaped and flocculent hot spots, with an accuracy rate of over 97% for component defect detection.

 

In the main control room, the Chint Intelligent Operation and Maintenance Cloud Platform displays the real-time operation status of the equipment on the large screen, making core information such as power plant health and equipment alarms clear at a glance.
Based on the previous inspection data of unmanned aerial vehicles and the intelligent analysis of Chint’s intelligent operation and maintenance cloud platform, the operation and maintenance personnel of the power station can comprehensively understand the operating status of the equipment, and effectively predict the prone areas and failure cycles, providing strong support for the long-term stable operation of the power station.

Through intelligent operation and maintenance methods, Akselutai Photovoltaic Power Station has achieved a leap from traditional operation and maintenance to intelligent operation and maintenance, building a digital system for full lifecycle management and setting a benchmark for the intelligent development of the photovoltaic industry.
Green economy, revitalizing the land of Longyuan
As one of the first batch of wind and solar power projects during the 14th Five Year Plan period in Gansu Province, Aksai Lutai Photovoltaic Power Station not only transforms desertified land into a new energy “blue ocean”, but also activates the green economic vitality of Longyuan.

 

During the construction and operation phases of the project, a large number of local farmers and herdsmen have been involved in the construction, directly driving employment and income growth; After the power station is put into operation, its annual output value has stabilized at 86 million yuan, becoming the core pillar of the new energy industry in Aksai County, effectively enhancing regional industrial output value, and supporting the coordinated development of rural revitalization and ecological economy.

Every spring and summer, the glaciers in the Qilian Mountains begin to melt, and a little green quietly appears under the blue photovoltaic panels.
The operation and maintenance personnel took off their heavy winter clothes, held an infrared thermal imaging device, and searched back and forth between the arrays, using technology and perseverance to write a new chapter in green energy in Gansu.
