GE selected to power Korean district heating scheme

Korea’s GS Power is preparing has selected GE’s high efficiency 7HA.02 gas turbine, and associated clutched steam turbine, for a new combined-cycle power plant in Anyang, Korea.

Anyang, a suburb outside of Seoul, experiences temperatures as low as -18 degrees Celsius, or zero degrees Fahrenheit, in the winter months. District heating, a network that distributes centralized heat to a concentrated population, helps mitigate these cold conditions and is GS Power’s primary application for the HA technology in Korea.

One hundred percent of the steam generated by the new plant has the potential to be used for district heating in winter months.

“GE’s 7HA technology has the largest steam exhaust energy output in the world, which will help us maximize our district heating needs in Anyang,” said Eung-Hwan Kim, Vice President, GS Power. “This output is a huge advantage for our customers, especially as we use this technology to replace the 23 year old aging plant.”

GE’s 7HA.02 gas turbine is the world’s largest and most-efficient 60-hertz gas turbine. In full power mode, it achieves more than 61 per cent efficiency and in district heating mode it achieves more than 91 per cent efficiency. The plant will have the capacity to generate 935 MW of power in combined cycle mode, the equivalent output needed to power 900,000 Korean homes.
