The company will provide its 7HA.02 gas turbine, which is said to be the largest-of-its-kind 60Hz gas turbine.
The new turbines will serve the district heating network that distributes centralized heat to tackle cold conditions in winter months.
GS Power vice-president Eung-Hwan Kim said: "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.
"This output is a huge advantage for our customers, especially as we use this technology to replace the 23 year old aging plant."
In combined cycle mode, the 7HA.02 turbine is claimed to generate 935MW power, which can serve 900,000 Korean homes.
GE Power & Water power generation products president and CEO Vic Abate said: "As the world’s largest and most efficient gas turbine, our HA technology is flexible to help serve very specific needs, like district heating in Korea, around the world."
With the latest order, GE has logged 17 orders for HA units. The company’s customers have technically selected 61 HA units.
