Gas Turbine Uprate Boosts Korean Power Plant Output

Posted on April 18, 2006

GE Energy recently completed seven gas turbine uprates at the SeoInchon combined-cycle power plant in Inchon City, Korea. The project will result in a 180 MW increase in output for the facility, which is owned by Korea Western Power Co., Ltd. (KOWEPO). One of the largest gas turbine uprate contracts ever awarded to GE, the agreement covered the upgrade of the turbine, auxiliary equipment and controls for each power train.

The uprate project involved removing the MS7001F gas turbines that form the core of the seven existing combined-cycle power trains, and replacing them with seven MS7001FA+e machines. GE's 7FA+e gas turbines represent the latest evolution in GE's F technology, benefiting from more than 14 years of operating and manufacturing experience (the original 7F units installed at SeoInchon are GE F-class fleet leaders in operating hours).

An upgrade on the first of the eight units at KOWEPO was completed in January of 2004. The performance test on this unit showed significantly improved performance, and paved the way for the award of the upgrade contract for the other seven gas turbines at the plant. The upgrade on the last of those seven machines was completed in April of 2006.

The eight-unit uprate project will increase both the output and efficiency of the plant, making KOWEPO one of the most competitive providers in the Korean power market. The SeoInchon plant produces power for the Korean grid, and is part of a 4000-megawatt complex in Inchon, the world's largest aggregation of GE F technology.
