Expansion of the district heating network in Ober- and Unterentfelden
Eniwa starts construction of a heating network in Entfelden. Planning permission has been granted for the first stage. The first households are to be supplied with district heating from 2026. Further construction is planned from 2028 to ensure a high level of long-term supply security.
With the heating network in Ober- and Unterentfelden, Eniwa AG will connect the next network to its grid, as detailed in a press release. The Buchs-based energy supplier has now received authorisation to build an energy centre and the first part of the network. From 2026, waste heat from the Buchs waste incineration plant(KVA Buchs) will supply CO2-neutral thermal energy to the first customers.
The first stage is scheduled to go into operation in 2026. According to the press release, it will enable the supply of thermal energy for a demand of 20,000 megawatt hours. Fewag is expanding the pipeline network from Suhr to the energy centre in Unterentfelden to transport the waste heat from the waste recycling plant to Entfelden.
The waste heat will be transported to the energy centre in the form of hot water and distributed to the buildings via the distribution network at 65 degrees Celsius. Aleksandar Dunjic, project manager for heating/cooling, uses the example of a central heating system to compare the cycle thus initiated. After being converted into thermal energy for heating and hot water preparation, the cooled water is transported back to the heat source.
After the first realisation phase by 2028, Eniwa is aiming to increase the amount of energy generated by district heating to 60,000 megawatt hours by expanding the network in Oberentfelden and Unterentfelden, according to the press release. “The district heating projects offer customers a high level of supply security at stable prices in the long term,” CEO Hans-Kaspar Scherrer is quoted as saying. The expansion targets are 12 kilometres of lines over the next 15 to 20 years.
