First Unit of Tianji Power Plant Expansion Begins Initial Operations

---

Researched by Industrial Info Resources China (Beijing, China)--The first unit (Unit 3) of the 1,320-megawatt (MW) Phase II expansion project at the Tianji Power Plant was connected to the grid on December 8, 2013, according to an announcement from Anhui Electric Power Construction No.1 Engineering Company (AEPC1) (Hefei, Anhui), the construction and erection contractor for the project and a subsidiary of China Energy Engineering Corporation (CEEC) (Beijing), on December 10.

The boiler of Unit 3 was ignited and the unit started up on December 5. The next day, the steam turbine of the unit started to run, and it reached the rated speed of 3,000 RPM on December 7. The unit was synchronized to the grid and began to generate electricity on December 8. During the commissioning, all technical indicators were rated at an excellent level.

The Tianji Power Plant is the first pit-mouth power plant built in the Huainan Coal and Power Base in central China's Anhui province. It is one of the main power source projects in the program to transmit power from Anhui to eastern China. The Phase II expansion project is furnished with two 660-MW, ultra-supercritical, coal-fired units, together with flue gas desulfurization and denitration devices on the reserved space of the existing plant area. The reheating steam temperature reached a record of 623 centigrade.

As one of the main contractors of the project, APEC1 is responsible for the construction of the main powerhouse in Bid 2, as well as the installation of Unit 3 and associated common and auxiliary facilities. Construction of Unit 3 kicked off on August 28, 2012, with the first concrete placement. The unit has achieved a series of milestones, from a boiler water-pressure test, an energizing of plant service power supply, the steam turbine box-up, boiler flushing and ignition.

According to the schedule, both units of the project will begin commercial operations shortly. Upon completion, all power generated from the project will be transmitted to Shanghai via the East China Power Grid, which will optimize the allocation of resources in eastern China and promote economic development in Anhui and Shanghai.
