China Energy Engineering Corp.

China Energy Engineering Corporation (CEEC, also known as Energy China) is a Chinese state-owned engineering and construction conglomerate established in 2011 through the reorganization of existing state energy engineering entities under the supervision of the State-owned Assets Supervision and Administration Commission (SASAC). Headquartered in Beijing's Chaoyang District, CEEC is publicly listed on both the Hong Kong Stock Exchange (HKG: 3996) and the Shanghai Stock Exchange (SSE: 601868). With over 116,000 employees, it is consistently ranked among the Fortune Global 500. CEEC is China's — and arguably the world's — largest integrated energy engineering and construction group, providing the full spectrum of services from planning, design, and engineering through to equipment procurement, construction, commissioning, and operation for power plants, transmission networks, renewable energy facilities, water infrastructure, and municipal systems.

CEEC's cleantech significance lies in its role as the primary EPC contractor and builder behind much of China's extraordinary renewable energy expansion. The company has designed and built hundreds of gigawatts of wind, solar, hydropower, pumped hydro, and energy storage projects across China, making it the organization most directly responsible for executing China's national energy transition strategy. It has also delivered significant international energy infrastructure projects across Southeast Asia, Africa, the Middle East, and Latin America. In the energy storage sector, CEEC was involved in building the 300 MW/1,500 MWh Hubei Yingchang compressed air energy storage project — one of the world's largest CAES plants — as an EPC contractor alongside State Grid Hubei Integrated Energy Services.

CEEC's business model is fundamentally different from a technology developer or energy generator: it creates no proprietary technology and holds no generation assets. Instead, it is the world's largest engineering services firm for energy infrastructure, its revenue driven by winning design, procurement, and construction contracts — often for national grid operators, provincial power companies, independent power producers, and international clients. The scale and breadth of CEEC's engineering capabilities — covering coal, gas, nuclear, hydro, wind, solar, tidal, biomass, geothermal, and storage — means that it is present in virtually every major type of clean energy project being built at scale in China today.

In recent years, CEEC has also expanded into the Power-to-X, green hydrogen, and offshore wind markets, aligning its construction capabilities with China's 14th Five-Year Plan priorities for clean energy acceleration. The company signed a contract in 2025 for a 2.1 GW solar-plus-storage project in Abu Dhabi, UAE (contract value approximately RMB 13.962 billion), one of the largest integrated renewables projects in the Middle East.
