Small-Scale Co-Generation


The small-scale co-generation system is a high energy efficiency
system that produces both heat and energy
, utilizing natural gas.
It has been adopted by many developed countries for its stability, environment friendliness,
economic feasibility and reliability. It is truly a next generation energy system.

Busan City gas’ energy efficient co-generation system improves overall system efficiency by 80%, reducing both energy consumption and greenhouse gas emission. In turn, our co-generation system enhances national energy efficiency by replacing the need of centralized power plant with small scale distributed generator.

  • Central Heating System: 140% (1.75 million won)
  • Individual Heating System: 135% (1.69 million won)
  • District Heating System: 127% (1.59 million won)

City Gas Co-Generation: 100% (1.25 million won) → to be reduced up to 40% annually

Advantages of small-scale co-generator
  • It enhances the property value where it is installed, making it more attractive to potential home buyers
  • It is more safe and convenient than individual heating
  • The system can supply electricity in stable manner even in times of natural disaster
  • The system provides professional energy management service, reducing overall energy cost for customers
  • The system alleviates heating imbalances among households within the system
  • National energy resources can be efficiently utilized by substituting large, centralized power plant
  • It helps the local and central government comply with international environment regulation such as Kyoto Protocol
