GE said commercial operation was recently achieved at GS Powerâ€™s Anyang Combined Heat and Power Plant Unit 2-1 in Anyang City, Gyeonggi Province of Korea, using one GE 7HA.02 gas turbine, one GE D652 steam turbine, one heat recovery steam generator (HRSG) and plant control system.
The company said the milestone was achieved eight weeks earlier than scheduled because of the 7HA gas turbineâ€™s innovative modular architecture and constructability. With pre-assembled modules, 7HA gas turbine requires fewer skilled work hours, reducing installation time and cost, and providing simpler and faster serviceability over time, the company said.
Anyang CHP is GEâ€™s first HA gas turbine delivered to and commercially operated in Korea, demonstrating GEâ€™s execution capability for extended scope projects to meet Korean customerâ€™s demand.
GS Power and GE have collaborated closely over the last several years to replace Anyang CHPâ€™s 26-year-old plant with cleaner and more efficient power generation technology, and 7HA.02 gas turbines and D652 steam turbines were chosen as the best technology that would serve the needs for electricity and district heating. GEâ€™s HA gas turbines are the worldâ€™s largest and the most efficient gas turbines, offering low life-cycle cost of electricity generation for 60Hz customers. Particularly for Anyang, the steam turbines play an important and active role to meet the district heating demand.
â€œThis is a meaningful project that will increase the efficiency at Anyang CHP through the adoption of GEâ€™s superior 7HA technology,â€ said Eung-Hwan Kim, vice president of GS Power. â€œWe will continue to partner with GE for the success of the unit 2-2 renewal project, to ensure a stable supply of heat in the Anyang region.â€
Through the modernization of Anyang combined heat plant, the plant is set to achieve more than 13 points of additional efficiency for electricity generation and eight points of additional efficiency for district heating respectively. GEâ€™s 7HA.02 gas turbine, GE D652 steam turbine, heat recovery steam generator (HRSG), and plant control system will also be installed at Anyang CHP unit 2-2.
