China Huaneng's Coal-Fired Addition at Nantong Power Plant Begins Full Operations

---

Researched by Industrial Info Resources China (Beijing, China)--Following the commissioning of the first 1,000-megawatt (MW) unit on January 13, the second 1,000-MW unit of Huaneng Nantong Power Plant's 2,000-MW Phase III expansion project passed the 168-hour, continuous, full-load trial and began commercial operations on February 26. Phase III is now fully operational, according to an announcement from East China Electric Power Design Institute (ECEPDI) (Shanghai).

During the trial operation, the unit was stable. The total installed capacity of the Nantong Power Plant has expanded to 3,400 MW.

The Huaneng Nantong Power Plant, located on the bank of the Yangtze River in Tianshenggang Town of Nantong City, in eastern China's Jiangsu province, was built in 1990. The power plant had four 350-MW coal-fired units, built in Phase I and Phase II. The Phase III expansion is a 50:50 joint investment by Huaneng Power International Limited (SHA:600011) (Beijing) and Nantong Tianshenggang Power Generation Company Limited (Nantong, Jiangsu), a subsidiary of China Guodian Corporation (Beijing).

The Phase III expansion includes two 1,000-MW, ultra-supercritical, coal-fired units in the reserved site of the existing plant. ECEPDI and Jiangsu Electric Power Design Institute (JEPDI) (Nanjing, Jiangsu) are jointly responsible for the design and engineering of the project. Tianjin Electric Power Construction Company Limited (TEPC) (Tianjin) is responsible for the construction.

Since the project kicked off in May 2012, it has achieved seven important milestones: the boiler water pressure test; the energizing of the plant service power; the steam turbine construction; the boiler ignition; the steam turbine startup; the first grid connection; and the 168-hour trial operation.

With the adoption of advanced large-capacity, high-parameter, low-coal-consumption and zero-emission technology, the project could generate more than 9 billion kilowatt-hours of electricity with annual sales income of about $655 million.
