First Unit of China Guodian's Jiujiang Power Plant Phase IV 1,320 MW Expansion Begins Operation

---

Researched by Industrial Info Resources (Sugar Land, Texas)--The first unit of China Guodian Corporation's (Beijing) Jiujiang Power Plant Phase IV 1,320 megawatt (MW) Expansion Project successfully passed the 168-hour full load continuous trial operation on December 27, 2012. This means that the first 660-MW steam turbine of 27 megapascals of high stream pressure in China has been put into commercial operation, according to an announcement made by China Guodian Corporation on December 28, 2012.

Guodian Jiujiang Power Plant, located in the east suburban of Jiujiang city in Central China's Jiangxi Province, is an old coal-fired thermal power plant initially built in 1977. The power plant currently has a total installed capacity of 1,350 MW, including two 125-MW units built in Phase I, two 200-MW units built in Phase II and two 350-MW units built in Phase III. Phase IV Expansion Project plans to have two 660-MW ultra-supercritical coal-fired units to replace the existing four units built in Phase I and Phase II. The project is jointly invested by China Guodian Corporation and Huainan Mining Group (Huainan, Anhui) in the proportion of 51:49. Jiangxi Electric Power Design Institute (Nanchang, Jiangxi) and Jiangxi Thermal Power Construction Company (Nanchang, Jiangxi) are responsible for the engineering and construction of the project, respectively.

The project received final approval from the National Development and Reform Commission, the top planner of China, on January 12, 2011. Construction of the project was then officially kicked off on March 28, 2011. On April 1, 2012, the roof of the main powerhouse was completed. On June 20, 2012, the generator stator was successfully erected to its final position. Commissioning of the unit was officially started after the completion of pipeline flushing on November 16, 2012.

With the adoption of ultra-supercritical technology, the design coal consumption of the project will be reduced to 284 grams per kilowatt-hour. In addition to the high steam pressure, the unit also has the lowest heat consumption among similar units in China.

Presently, the project owner is working together with related parties for the commissioning of the second 660-MW unit in the project. According to the schedule, the entire project will be fully completed in the first quarter of 2013.
