Today, electricity-based heating accounts for approximately eight percent of total district heating production, but in recent years many district heating plants are moving towards a more electricity-based future. The sector expects that electricity-based heating from, among other things, electric boilers and large heat pumps will account for between 15 and 25 percent of total district heating production by 2027. Although this is good news for the climate, it also places great demands on the electricity grid.
Electricity-based district heating plants with heat pumps and electric boilers use a lot of electricity – in fact, some of the largest plants have a need corresponding to the electricity consumption at its peak in cities such as Aalborg and Esbjerg – and therefore often require expansions of the electricity grid.
To ensure a high pace in the transition, Elnetselskabet N1 and Dansk Fjernvarme have entered into a collaboration that will make the process easier for both the electricity grid and district heating companies. This is stated by N1 in a press release.
- We are massively expanding the electricity grid these years to, among other things, support the electrification of district heating, the spread of electric cars and the massive increase in electricity production from renewable energy. If we are to do this as efficiently as possible, we need close dialogue between us and the various sectors, and therefore, together with Dansk Fjernvarme, we have created a handbook that guides both us and the heating plants through the transition to more electricity, says Lise Bering, CEO of Elnetselskabet N1.
Provides answers to several problems
When district heating companies need to have a new electric boiler or heat pump connected to the electricity grid, this is done through electricity grid companies such as N1. However, the electricity grid companies are not allowed to plan or initiate the work before the district heating companies have actually ordered and paid for the connection. This is done to avoid unnecessary expansions of the electricity grid and reduce the financial risks for electricity consumers. If the heating plants are not prepared for this, it can affect the pace of their electrification plans.
These are often the type of issues that Dansk Fjernvarme spends a lot of time preparing its members for. This and many other insights are therefore now collected in the handbook.
- District heating companies are facing massive electrification and in many places they are already underway. To ensure that the transition is as smooth and cheap as possible, it is good to formalize cooperation with the grid companies. This will give the grid companies earlier information about what the utility companies are demanding, and the district heating companies will be certain about when they should reach out, to whom they should do it, and what it otherwise requires to get their plants connected without compromising security of supply, says Michael Søgaard Schrøder, chief consultant at Dansk Fjernvarme.
