China Huaneng Group (CHNG) was established in August 1988. "Hua" means China, while "neng" means energy. It is a large-scale state-owned enterprise with 20,000 employees and headquarters in Beijing. The company's core business is power generation. In 1991 CHNG was listed among the first batch of experimental large-size groups in China. In 1996, CHNG merged with the State Power Corporation of China. It is a holding company of many power companies; it also has many peripheral businesses in telecommunications, real estate, finance, cement, and electrical appliances. Most are vertically integrated. CHNG reports to the State Power Corporation of China, which is a part of the government. Consequently, this is a true state-owned enterprise.
