Korea District Heating Corporation (KDHC) was established in 1985 and supplies district heating to about 1.41 million households as of the end of 2016. Korea’s metropolitan area is densely populated, and over the past 30 years, more towns have been developed near metropolitan areas. Due to this development district heating systems in Korea have been rapidly spreading.
Currently, all DH systems in Korea are 3G. Building insulation standards have been continuously strengthened over the past decade, and the government’s acts for the use of new and renewable energy have been also been reinforced. KDHC finds it necessary to develop a new district heating system linked to renewable energy in existing district heating systems.
In connection to this, they are interested in learning more about the currently operating 4G DH systems in Europe. The delegation visited Denmark the 26th and 27th of April to study Danish 4G DH systems. During the visit, the delegation was introduced to Danish sustainable energy solutions at State of Green. They also visited the city of Albertslund, where they got at hands on introduction to Danish 4G DH.
