District heating refers to a method in which individually installed heat production facilities for apartments, commercial buildings, offices, and various other structures within a specific area are not used. Instead, economically produced heat (hot water) from a centralized, large-scale heat source facility is uniformly supplied through buried heat transmission pipelines.
-
Excellent Cost Efficiency
This results in savings in self-generated heat production facility replacement costs and maintenance expenses.
-
Reduction of Environmental Impact on the Atmosphere
The installation of advanced pollution control facilities reduces emissions of air pollutants and carbon dioxide, leading to environmental improvement.
-
Convenient Usage
It is possible to maintain a consistent indoor temperature and provide hot water usage 24 hours a day.
-
Energy Conservation
The use of combined heat and power generation for district heating results in higher energy efficiency compared to conventional power generation.
-
Thorough Safety Management
There is no risk of fire, explosion, or suffocation accidents as there is no need for self-generated heat production facilities like boilers, as well as fuel storage and transportation facilities.
District cooling is an advanced cooling system that involves converting economically produced hot water from large-scale heat production facilities into cold water through conversion equipment and using it to cool a specific area. This system reduces summer peak power demand through the use of electric alternative energy sources, such as excess heat from power plants.
-
Environmental Impact Reduction
It has an environmental impact reduction effect by using water as a refrigerant instead of greenhouse gases that contribute to global warming.
-
Alleviating Summer Peak Power Shortages
The characteristics of LNG power plants that can respond immediately to the urgent requests of the power exchange contribute to mitigating the summer peak power shortage.
-
Maximizing Energy Utilization Efficiency
It maximizes energy utilization efficiency by simultaneously producing electricity and heat using fuel, and it also utilizes waste heat from facilities such as incinerators and steel mills.
As of 2021, the electricity produced and supplied through the CHP (combined heat and power plant) was approximately 810,000 MWh, while approximately 803,000 Gcal of district heating was supplied to around 68,000 households through CHP, PLB (peak load boilers), external heat sources, etc. The goal is to expand heat production and demand to approximately 110,000 households by 2025, supplying 1,041,000 Gcal of district heating and continuing efforts to explore new businesses.
