GS Power

GS Power operates a 1,400 kW rooftop solar power plant by leasing the roof of GS Retail's logistics center, and it also operates a 1,000 kW solar power plant in Yeongyang, Gyeongsangbuk-do. Additionally, GS Power leases the roof of KORAIL's vehicle service center and operates a 2,600 kW solar power plant.

Fuel cells are a high-efficiency, environmentally friendly power generation system that converts the chemical energy of hydrogen and oxygen into electrical energy through electrochemical reactions. GS Power has been operating a 4.8MW-class phosphoric acid fuel cell (PAFC) power generation facility in Anyang combined heat and power plant since its installation in September 2010, and a 10.5MW-class phosphoric acid fuel cell (PAFC) power generation facility in Bucheon combined heat and power plant since its installation in May 2020. Fuel cells generate energy without combustion reactions, resulting in minimal emissions of pollutants such as carbon dioxide and nitrogen oxides, making them an eco-friendly power generation system compared to conventional internal combustion engines.

GS Power operates small hydroelectric power plants with capacities of 270kW at the Deoknam Water Purification Plant in Gwangju and 760kW at the Yongyeon Water Purification Plant.

Near the Cheonbuk Industrial Complex in Gyeongju City, GS Power has been operating three 2.35MW wind turbines since December 2016, producing approximately 14,000MWh of electricity annually.

To reduce peak power loads, GS Power completed the installation of a 500kW (PCS)/1,000kWh (Battery) ESS at the Anyang combined heat and power plant in December 2017 and has been operating it.
In addition, the Cheonbuk Wind ESS business, linked to the wind power plant, was installed in December 2016 with a capacity of 1,000kW (PCS)/3,000kWh (Battery) and is currently operational.
