GE technology to drive 300 MW South Korea IGCC plant

Seoul, South Korea, January 10, 2012 — GE technology has been selected by Korea Western Power Co. for a integrated gasification combined-cycle (IGCC) power plant to be built in South Korea and one of the first in Asia.

The 300-MW coal-fired facility will help the South Korean government meet its low carbon emissions targets, while bolstering the country's electricity supply.

GE will supply a 7F Syngas Turbine, a D11 steam turbine, a heat recovery steam generator and a cyber security-featured Mark VIe integrated control system that will run the power island control system for the new plant.

GE also will provide 10 years of maintenance services for the facility, located 20 kilometers northwest of the city of Taean-Eub and about 100 kilometers south of Seoul.

The Taean IGCC project is the first commercial gasification combined-cycle plant to be developed under South Korea's Renewable Energy Portfolio Standard. The government has provided research and development funding for the gasification process.

Specifically designed for IGCC applications, GE's 7F Syngas Turbine operates on cleaner burning syngas fuel produced from coal. For the Taean plant, the turbine will operate on syngas produced from the gasification of low BTU coal. Key equipment for the project will be shipped during the first half of 2014, with the plant's commercial operation to start in late 2015.

GE is a pioneer in the development of syngas turbine technology and has provided syngas-capable gas turbines for several milestone IGCC projects, including the pilot Coolwater IGCC plant in Barstow, Calif., and Tampa Electric's 250-MW Polk Power Station in Florida.

Turbines for the South Korea plant use the same technology as the turbines to be used in one of the largest IGCC plants in the world, which is slated to be commissioned in 2012.

To date, GE's Heavy Duty Gas Turbines have accumulated more than 1.3 million operating hours on syngas, including 400,000 operating hours on F-class gas turbines. GE's syngas turbines are an enabling technology for IGCC, which allows for the efficient production of electricity via the conversion of coal to gas, in a process that removes pollutants from the gas.

The scope of GE's contract for the Taean project includes power island control, which will be handled by a GE Mark Vle ICS that interfaces with the gasification and air separation units.

Key features of the system will include vibration monitoring for the power island as well as interface with the entire plant vibration monitoring package; performance monitoring of the power island only; cyber security features for the GE Mark Vle ICS; interface with a centralized power generation management system consisting of multiple South Korean power plants; and a master clock for total plant time synchronization, including the gasification and air separation units.
