The Danish district heating model

The Danish district heating sector provides 64 percent of all Danish households with district heating. This makes Denmark one of the countries in Europe that has the most developed district heating supply networks. This is due to the fact that Denmark, in the wake of several energy crises in the 1970s, adopted its first Heat Supply Act in 1979. 

This Act introduced extensive public heating planning that secured a collective heating supply and a socially-appropriate exploitation of energy. However, the development of the collective heating supply required massive investments for production and distribution. Therefore, obligatory connection was introduced for new and existing residential projects in district heating areas, to ensure a sufficient customer base and the socio-economic benefits that the collective heating supply was able to provide. 

District heating production is decentralised, as production is generally reliant on being in the vicinity. This means that there is/are often only a single or just a few heating suppliers to the local district heating network. This means that the Danish district heating industry is regarded as a natural monopoly and is regulated by a principle of non-profit. This principle dictates which costs can be covered in the heating price. Likewise, the price of district heating must not exceed the cost of heat production. This ensures that customers are protected against possible abuse as a result of the industry’s natural monopoly state. 

In addition to municipally-owned companies, a large proportion of Danish district heating companies are operated as cooperatives. This means that the cooperative is owned by its own customers and works to promote their common interests. Alongside the non-profit principle, this creates an efficient heat supply at the lowest possible price for the end customer.
