The Gangneung Anin power project is a 2,080MW coal-fired power plant under construction in the Gangwon province of South Korea.

Gangneung Eco Power (GEP), a special purpose company formed by Korea South-East Power (KOEN) and Samsung C&T Corporation in June 2014, is developing the project with an estimated investment of £3.7bn ($5bn).

KOEN, a wholly-owned subsidiary of state-owned Korea Electric Power Corporation (KEPCO), holds 29% stake in the independent power producer (IPP) project and will be responsible to operate and maintain the facility for 30 years. Samsung C&T is leading the construction of the power station.

The main construction of the power plant started in March 2018, with the first coal-fired unit expected to come online in September 2022 followed by the commissioning of the second unit in March 2023.

Gangneung Anin power project location

The Gangneung Anin coal-fired power plant is located at Anin, Gangdong, near Gangneung, in the Gangwon province of South Korea.

Gangneung Anin coal-fired power plant make-up

The Gangneung Anin power plant will comprise two 1,040MW ultra-supercritical (USC) coal-fired units.

Each unit will be equipped with a once-through boiler designed to produce steam at 613ºC temperature and 264kg/cm2 pressure, and a high-efficiency steam turbine.

The plant will use bituminous coal for power generation and seawater for cooling.

Other components of the plant will include air compressors, condensers, auxiliary boilers, generators, transformers, and a gas-insulated switchyard.

The plant will also be fitted with deaerators, electrostatic precipitators (ESP), and flue gas denitrification and desulphurisation systems to control emissions.

Power evacuation

The electricity generated by the Gangneung Anin coal-fired power plant will be evacuated into the grid through a 345kV transmission line.

Financing for the Gangneung Anin coal-fired power plant

The Gangneung Anin coal-fired project is being financed through £3.21bn ($4.34bn) debt provided by 34 financial institutions.
