The commercial operation allows South Korea to reduce carbon emissions per unit of fuel used at the plant and supports a stable supply of heat and power in the Anyang region.
Anyang District Heating Plant Unit 2-2, located in Anyang City, Gyeonggi Province, South Korea, adds approximately 500 megawatts (MW) to the national grid, the equivalent needed to power approximately 500,000 South Korean homes as well as steam for district heating for over 180,000 households in Anyang City. The commercial operation for GS Power’s Anyang Combined Heat and Power (CHP) Plant Unit 2-2 consists of the renewal of older gas-powered assets with the latest turbine technology including one GE 7HA.02 gas turbine, with a matching GT H65 generator, one STF D650 steam turbine and a ST A39 generator, along with a Mark* VIe Distributed Control System (DCS) software solution and services to support the availability and reliability of the plant. Amidst the COVID-19 pandemic and extraordinary heavy rains and typhoons, the commissioning work was executed safely to ensure the plant achieved commercial operations one week ahead of schedule.
The Anyang District Heating Plant benefits from GE’s HA technology which is capable of
reaching close to 62.2 percent net plant efficiency in combined cycle and more than 93 percent efficiency in district heating mode. District heating mode is enabled by industry leading steam turbine
flexibility, allowing for high efficiency in both district heating and power only modes. This
process captures and reuses excess heat or steam that would otherwise be released into the
environment or go unutilised, effectively generating more energy and less carbon emissions
per unit of fuel.
“Following GE’s successful modernisation of Anyang CHP Unit 2-1, we chose to continue to
partner with GE for the success of the second unit renewal project to support our efforts in
delivering cleaner and more efficient combined heat and power to homes and businesses in the
Anyang region,” said GS Power. “We trust in GE’s technology to help us in meeting the energy
and heating needs of our communities in Anyang City, while reducing our plant’s carbon footprint. This project is also contributing towards the country’s goal laid out in the government’s Green New Deal to achieve carbon neutrality by 2050.”

The plant is set to achieve more than 13.8 percent points of additional efficiency for electricity generation. Similar to the Naepo and Kospo district heating projects, Anyang CHP plant will connect to Korea’s Direct Heating System (DHS), a centralised system which distributes heat to residential developments since the 1990s. With a growing population of nearly 52 million, DHS delivers energy efficiency on a national level and has enabled better urban planning. The use of district-wide direct heating and cooling systems has helped South Korea contain carbon emissions, relative to the impact
of individual heating and air-conditioning systems in line with the expansion of densely
populated communities.
“Gas power generation plays a critical role in facilitating South Korea’s transition to a more
energy efficient, reliable, and lower carbon future” said Ramesh Singaram, President & CEO GE
Gas Power Asia. “Since Korea’s long-term goal is to increase its reliance on renewable power
sources, gas turbine technology is crucial to ensure the needed power to balance the variable
nature of renewables and ensure system reliability at all times. We’re proud to work with GS
Power to support South Korea’s district heating needs with a highly efficient energy solution
that delivers energy savings and reductions in CO2 and NOx emissions.”
