The agreement combines advanced energy-efficient equipment manufacturing with industrial EPC expertise to pursue domestic and international opportunities in zero-carbon industrial parks, data centres, and high-tech manufacturing infrastructure.
On July 7, Shuangliang Eco-Energy Systems and China Electronics System Engineering No. 2 Construction Co. (CESE2) signed a strategic cooperation agreement to strengthen their presence in domestic and international markets by combining manufacturing capabilities with industrial engineering expertise.
The partnership focuses on four areas: market development, engineering collaboration, supply chain integration, and expansion into emerging sectors including zero-carbon industrial parks and data centres. This reflects a broader trend in China’s industrial decarbonization strategy, as equipment manufacturers and EPC contractors increasingly combine their capabilities to deliver integrated low-carbon infrastructure. It also highlights how China’s dual-carbon agenda is reshaping competition across advanced manufacturing, clean energy and digital infrastructure.
Partnership strengthens integrated industrial delivery
Shuangliang and CESE2 will establish a long-term strategic partnership covering domestic and overseas business development, engineering delivery, supply chain coordination, operations and maintenance services, and new energy projects.
The collaboration brings together complementary strengths. Shuangliang has established a strong position in energy-saving technologies, water conservation, environmental protection equipment and clean energy systems. For over four decades, it has developed advanced manufacturing capabilities and digital technologies that help industrial customers improve energy efficiency and accelerate the transition to lower-carbon operations.
CESE2 contributes extensive expertise in complex industrial facilities. Founded in 1953 and headquartered in Wuxi, it is China’s earliest state-owned enterprise specializing in cleanroom engineering and industrial construction. The company operates under China Electronics Corporation (CEC), a Fortune Global 500 company.
Together, the partners offer an integrated value proposition: Shuangliang supplies energy-efficient technologies and equipment, while CESE2 provides engineering design, EPC delivery and lifecycle facility management. This combination enables customers to procure end-to-end industrial infrastructure solutions, from project planning and construction to long-term operations and maintenance.
The partnership also responds to growing demand for turnkey industrial decarbonization. Manufacturers increasingly prefer integrated delivery models that combine plant design, energy infrastructure, digital management platforms and operational optimization. Such an approach can improve execution efficiency, reduce coordination risks across multiple contractors and generate recurring revenue through long-term operations and maintenance.
Technical capabilities target high-specification industries
The partnership is particularly relevant for industries that require highly controlled production environments alongside stringent energy-efficiency standards.
CESE2 is one of China’s leading contractors in cleanroom engineering and high-tech industrial EPC. It was the first company in China’s clean engineering sector to receive the country’s highest construction honour, the Luban Award, which it has won seven times, reflecting its expertise in delivering technically demanding industrial projects.
Its Lean EPC (L-EPC) model integrates project consulting, engineering design, procurement, construction, commissioning and long-term operations and maintenance. This lifecycle approach has become increasingly valuable as manufacturers focus on optimizing total cost of ownership rather than minimizing upfront construction costs.
CESE2’s portfolio includes semiconductor fabrication plants, integrated circuit manufacturing facilities, pharmaceutical and biotechnology plants, lithium battery and photovoltaic manufacturing sites, and hyperscale data centres.
These facilities require tightly controlled operating environments, including precise air cleanliness, temperature and humidity control, supported by highly efficient utility systems. Advanced cooling, water treatment and energy management technologies are therefore critical to operational reliability, energy efficiency and sustainability.
Shuangliang’s portfolio aligns closely with these requirements, encompassing energy-efficient cooling systems, water management solutions, industrial waste-heat recovery technologies and digital zero-carbon platforms that help industrial operators reduce resource consumption, lower emissions and improve operating efficiency.
Commercial value extends beyond technology integration
The commercial rationale is equally compelling.
CESE2 reports annual revenue exceeding CNY20 billion and a workforce of around 10,000 employees across more than 30 branches and 10 subsidiaries, providing substantial engineering capacity and nationwide project delivery capabilities. Its established customer base in electronics, healthcare and new-energy manufacturing also expands Shuangliang’s access to industrial projects.
Shuangliang, meanwhile, has expanded its international footprint through large-scale industrial developments, including United Solar Polysilicon’s 100,000-tonne-per-year high-purity polysilicon plant in Sohar Freezone, Oman.
Commissioned in February 2026, the facility is the first polysilicon plant outside China built entirely to Chinese standards. Shuangliang supplied more than USD 58 million of proprietary process equipment, including high-capacity polysilicon reduction furnaces, intelligent green hydrogen generation systems and high-efficiency absorption chillers that recover industrial waste heat and improve overall plant energy efficiency.
The project also highlights the scale of the global polysilicon market. According to the China Photovoltaic Industry Association (CPIA), global polysilicon production reached approximately 1.485 million tonnes by the end of 2025, comprising 55,000 tonnes of electronic-grade polysilicon and 1.43 million tonnes for solar applications, including both chunk and granular polysilicon.
The Oman project demonstrates Shuangliang’s ability to deliver integrated process technologies for globally competitive manufacturing facilities while strengthening its credentials in international industrial decarbonization. Combined with CESE2’s EPC expertise, the partnership could enhance both companies’ competitiveness in overseas industrial infrastructure markets.
Growth markets: Data centres and zero-carbon infrastructure
A defining feature of the partnership is its focus on zero-carbon industrial parks and data centres – two sectors that are emerging as strategic priorities within China’s industrial and digital infrastructure agenda.
As AI, cloud computing and digital services drive rapid growth in computing demand, data centres are becoming increasingly energy intensive. Improving cooling efficiency, reducing water consumption and integrating renewable energy have therefore become central design priorities for next-generation facilities.
At the same time, zero-carbon industrial parks are becoming important demonstration projects supporting China’s carbon neutrality objectives. These developments typically integrate renewable power, intelligent energy management, energy storage, high-efficiency cooling, digital monitoring and low-carbon industrial operations within a unified infrastructure platform.
By combining Shuangliang’s energy technologies with CESE2’s engineering expertise, the partnership is well positioned to address the increasingly sophisticated technical and operational requirements of these projects in both domestic and international markets.
Strategic implications
The agreement reflects a broader evolution in China’s industrial landscape, where collaboration between leading equipment manufacturers and major engineering contractors is becoming an increasingly important driver of industrial upgrading.
For policymakers, such partnerships support national priorities including advanced manufacturing, green industrial transformation, digital infrastructure expansion and international market development. For industrial customers, the collaboration offers integrated project delivery, streamlined procurement and improved operational performance through coordinated engineering and technology deployment.
More broadly, the partnership illustrates the convergence of clean energy, advanced manufacturing and digital infrastructure. As industrial value chains become more integrated, competitive advantage is likely to depend less on individual products or engineering capabilities than on the ability to deliver comprehensive, lifecycle-based industrial solutions at scale.
