A chain spanning from coordinated scheduling of computing power and electricity to green electricity transmission across more than 2,000 kilometers was presented at the Clean Energy Chain exhibition area of the fourth China International Supply Chain Expo, held from June 22 to 26 in Beijing. Several Chinese energy central state-owned enterprises demonstrated their progress in greening and smartening the energy supply chain through specific projects and solutions.
In computing-power coordination, China Energy Engineering Group and China Energy Conservation and Environmental Protection Group offered solutions from system scheduling and industrial support perspectives, respectively. According to Suo Debo, general manager of the Market and Financing Department of China Energy International Group, the enterprise pioneered an integrated green power supply scheme called "source-grid-load-storage integration." Its Gansu Qingyang zero-carbon smart computing industrial park, part of the "east-data-west-computing" project, is equipped with a 200MW new energy power station and storage facilities, securing low-cost green electricity around the clock for computing centers through medium- and long-term power transactions that lock in tariffs. The scheme also utilizes the "Rongguang" AI large model to develop flexibly schedulable computing operation plans, breaking down barriers between power dispatch systems and data center management systems, guiding computing loads to shift operation timing based on new energy output periods, and enabling two-way interaction between power and computing. Additionally, drawing on its experience in formulating over 20 energy industry standards, China Energy Engineering Group collaborates with computing sector institutions to establish unified technical specifications for computing-power coordination, addressing weaknesses like inconsistent standards and cross-industry data interfaces.
China Energy Conservation and Environmental Protection Group completes the industry loop with green electricity supply, AI empowerment, park carriers, and material support. As of end-May 2026, the group's green electricity installed capacity stood at 27.53GW, using wind, solar, waste-to-energy, and regional clean energy supply to form a multi-energy complementary matrix to provide stable green power for computing centers. Its self-developed large model for the energy conservation and environmental protection industry incorporates 108 proprietary AI models, covering energy production, storage dispatch, and carbon management. The group is also building source-grid-load-storage integration demonstration scenarios in 51 of its own zero-carbon parks and advancing domestic production of high-end new materials needed for storage, solar, and computing server rooms.
Cross-regional green power delivery was also highlighted. China Resources Power showcased its "Xinjiang Power to Chongqing" project, where two 1,000MW units of its Chongqing Energy Xinjiang Company generate electricity, transmitted via an ±800kV UHVDC line. The power travels 2,260 kilometers from Xinjiang to Chongqing in just 7 milliseconds, with cumulative transmission exceeding 6.5 billion kWh, serving as the energy backbone for the Chengdu-Chongqing economic circle. It is China's first outbound coal-power project supporting a large-scale wind-solar base in sandy, rocky, and barren areas.
The transformation of traditional energy companies also drew attention. CNOOC General Manager Huang Yongzhang stated that high-level international cooperation is essential for strengthening industry chain resilience. CNOOC's overseas oil and gas operations span 17 countries, with a natural gas supply system built from resources across more than 30 countries and regions. Hu Senlin, deputy secretary of the Party Committee, vice president, and labor union chair of CNOOC's Energy Economics Institute, introduced that the company has moved beyond traditional offshore oil and gas to marine energy and resources, displaying deepwater assets like the "Shenhai Yihao" platform and explorations into deep-sea floating wind power. The company has commissioned China's first deep-sea floating wind platform, first offshore oilfield solar-storage station, and first offshore CCUS demonstration project, and formulated a new industrial system to promote large-scale offshore wind power development during the 15th Five-Year Plan period while exploring marine energy and strategic minerals.
Sinopec Vice President Chen Yanbin noted that the world economy cannot retreat into isolation and that the company is promoting clean utilization of fossil fuels, scaling up clean energy, and low-carbon production processes, building a pattern where traditional energy coexists with new forms like wind, solar, thermal, hydrogen, and biomass. The company has built China's first shale gas field with proven reserves exceeding 1 trillion cubic meters—the Fuling field, commissioned the country's first million-tonne CCUS demonstration project, built the world's largest PV-based hydrogen production project and largest hydrogen refueling station network, ranked first in geothermal heating area nationwide, and used its proprietary bio-jet fuel in a domestic large aircraft for the first time.
Vice Chairman of the China Council for the Promotion of International Trade Liu Jiannan said at the expo that advancing energy transition is a must-answer question for sustainable development.
