New and Renewable energy

New and Renewable Energy: New and renewable energy is the most efficient, economically available energy when connected with the district heating system. The waste incineration heat and methane gas emitted from landfill are recovered and used for the production of district heating heat, and wood-based biomass, SRF, sewage heat, biogas, geothermal, and photovoltaic are also useful energy resources in conjunction with the cogeneration and district heating network.

Photovoltaic

A total of 5.8MW photovoltaic facilities are in operation, including Daegu, Shinan, Bundang, Pangyo, Suwon, and Yangsan, and 2.4MWh of electricity is produced annually (as of 2020).

Wind Power

Wind power in Shinan, Jeollanam-do Province (63MW)
- A large-scale wind power generation project was implemented in Jaeun-do, Sinan-gun, Jeollanam-do Province, and commercial operation began in June 2020 (joint project)
Wind power project in Yangsan (10MW)
- Promotion of wind power generation project to expand renewable energy in Eden Valley, Yangsan, started commercial operation in May 2014 (a joint project)

Waste Energy

Incineration heat and incineration vapor

Using incineration heat, 1,671,000 Gcal (as of 2020) of heat has been generated annually, and 79,000 MWh of electricity has been produced by the incineration steam (as of 2020).

Expansion of new and renewable energy business

Performing a new and renewable energy project with facility size of 22MW + 45Gcal/h using solid fuel (SRF) in Gwangju Jeonnam Innovation City
- This is a power plant that segregates combustible wastes from household waste and turns them into fuel to produce SRF, which is used to generate energy. By supplying more than 20,000 households, public institutions, and business buildings in the Joint Innovation City of Gwangju and Jeollanam-do Province, district heating and electricity can be provided, replacing the annual energy import cost of about 13 billion won and saving about 120,000 tons of greenhouse gas.

Utilization of landfill gas, bio-gas and sewage heat

Production of 158,000 Gcal (as of 2020) of heat per year using landfill gas (LFG) and biogas
- Landfill gases (LFG) generated from waste landfills in Nanjido-Seoul, Daegu, are collected and used as heat source for district heating, contributing to the consumption of waste resource as energy and improving the atmospheric environment.
- A cogeneration project is carried out to generate heat and electricity by utilizing the biogas generated by the Mapo Nanji Water Regeneration Center.
- Heat energy generated from groundwater and sewage treatment water whose temperature is lower than the air temperature in summer and higher in winter is recovered with heat pump and used as heat source for district heating.

Woodchip

The Daegu branch expanded the production of new and renewable energy to 90,000 Gcal and 17,000MWh (as of 2020) by using (processed and crushed) pine wilt disease-afflicted wood discarded from the forest.

Hydrogen Energy and Fuel Cell

Fuel cell is a highly efficient, eco-friendly power generation system that produces electricity and heat energy through the electrochemical reaction of hydrogen and oxygen.
The Dongtan branch operates its own fuel cell facility (11.44MW + 8.8Gcal/h) and SPC-type Noeul fuel cell facility (20MW + 10Gcal/h).
