Sunpower Group Ltd. delivers environmental protection and energy solutions primarily within the People's Republic of China. The company's primary focus is now its Green Investments segment, following the divestment of its Manufacturing & Services business in 2021. Through its Green Investments segment, Sunpower specializes in the investment, development, and operation of centralized facilities. These facilities are dedicated to supplying clean industrial steam to a broad spectrum of industries located within industrial parks. Additionally, the company provides pollution-free civil heating to residential areas and electricity to the State Grid. Certain projects also extend to supplying other industrial necessities, such as compressed air. This segment operates on a business-to-business model, characterized by long-term, typically exclusive concessions spanning around three decades, which generate consistent, high-quality recurring revenue. Sunpower's solutions support China's "Dual Carbon" goals by promoting energy efficiency, circular economy principles, and significant reductions in emissions, often achieving levels below national standards for natural gas. The company serves a diverse client base across more than 20 industries, including textiles, pharmaceuticals, food processing, paper, and chemicals. Recent activities include a strategic collaboration agreement with Jining Energy Development Group in July 2025 and the receipt of a substantial biomass subsidy for its Xintai project in August 2025. Sunpower Group Ltd. was established in 1997 and is headquartered in Nanjing, the People's Republic of China.
