Kospo, South Korea’s largest electric utility, needed a way to provide a higher reserve margin, which had dipped as low as 4% during peak demand periods. Given the rise in demand due to a positive economic environment, Kospo looked to upgrade their fleet of 7F gas turbines to provide additional capacity while controlling emissions.
Kospo upgraded two 7F gas turbines with the Advanced Gas Path (AGP) hardware upgrade and the OpFlex software solution, marking the 100th of these systems sold to date. The combined solution offered Kospo industry-leading gas path upgrade performance and operational flexibility by increasing gas turbine output, efficiency and availability. The upgrade was installed on two units at its Busan plant in Incheon to support the region’s population growth and economic expansion.
The results of the upgrades were compelling for Kospo, who had weighed the economics of building a new plant versus upgrading existing facilities with the GE AGP and OpFlex solutions. Both the Shin-Incheon and the Busan plant locations experienced greater power production capacity and operating efficiencies. Combined, these two locations are now producing an additional 215 Megawatts of power — enough to energize 160,000 homes.
