Large electric kettles can be compared to the electric kettle from the kitchen. The boiler heats the water via electricity, and the water is then passed through a heat exchanger. Here it releases heat to the district heating water, which is thereby heated to flow temperature and then sent out into the district heating network.

Billion-dollar investment: Hofor wants to utilize more wind and solar energy in district heating

Hofor is investing in large electric boilers for district heating to utilize solar and wind energy.

With the goal of reducing the use of biomass and fossil fuels such as oil and natural gas, Hofor announced in January the purchase of large heat pumps, which will make district heating in the capital area greener.

Now the utility company will build on these green ambitions by investing billions in electric boilers, which will supplement the upcoming heat pumps.

By supplementing heat pumps with electric boilers, it will be possible to produce electricity-based heat to an even greater extent at low electricity prices when the sun is shining and the wind is blowing. The investment decision also includes small, local heat storage. When there is a lot of electricity from wind turbines and solar parks in the electricity system, the heat can be stored and used a few hours or up to a day later, when heat is needed, Hofor said in a statement.

- We really want to contribute to the green transition. That is why we are now making another ambitious investment. This time of 3-5 billion. over the next few years to generate heat for our customers via electricity-based solutions – this will reduce the use of biomass and fossil fuels. With electricity-based solutions in the district heating system, heat for Copenhageners can come from solar and wind energy to a much greater extent, says Gorm Elikofer, Director of Energy at Hofor.

According to Hofor analyses, the expansion with first heat pumps and now electric boilers will result in biomass consumption at CHP plants in the capital area being reduced by 30-35 percent by 2033 at the latest, measured in relation to current district heating consumption. The investment will also provide more multi-strand district heating.

- When we base the heat on several technologies, the supply becomes more robust to, for example, delivery difficulties and price fluctuations on biomass, electricity and natural gas. This means that it is easier to ensure a more stable price for customers and high security of supply in turbulent times, says Gorm Elikofer.
