  • Rhine water and waste heat as an energy source for the heating network

    Rhine water and waste heat as an energy source for the heating network

    The electricity supplier AEW Energie AG, based in Aarau, is investing over 8 million Swiss francs in the new Augst BL heating network, according to a press release. This will replace the existing AEW contracting plant in Pratteln BL, which is fuelled by wood pellets and oil. The planning application for the heating network, which will run on 100 per cent renewable energy, has been submitted. The first heat supply is scheduled for the 2025/26 heating period.

    The heating centre will be built in the machine hall of the Augst power plant and will use the waste heat from the power plant generators and Rhine water as heat sources. The waste heat from the generators is currently discharged unutilised into the Rhine. With this combination, a reliable and sustainable heat supply can be guaranteed, according to AEW. Three heat storage tanks, each with a capacity of 16,000 litres, serve to compensate for fluctuations and ensure a constant supply.

    The heat is distributed to the connected buildings via a district heating network that is around 1.3 kilometres long. According to the press release, a total thermal output of 2 megawatts will be provided, with a planned annual heat output of 4,400 megawatt hours in the final stage of expansion. Compared to fossil heating systems, this corresponds to a reduction of around 1200 tonnes of CO2 per year.

    According to the press release, AEW began developing heat supply systems in the early 1990s. The first heating network was put into operation 30 years ago in the municipality of Möhlin. Today, AEW operates 75 heating networks and contracting plants for heating and cooling in the canton of Aargau and neighbouring cantons. The current production capacity is over 230 gigawatt hours per year and avoids the emission of around 55,000 tonnes of CO2 per year.

  • Sustainable energy supply for Frick

    Sustainable energy supply for Frick

    The Basel-based energy supplier IWB has announced the commissioning of the Frick heating network. In addition to the new heating centre with two wood-fired boilers and two heat storage tanks, a 2.1-kilometre-long heating network has also been put into operation, according to a press release. The expansion of the final sections in the first construction phase is to begin on 4 March.

    This will supply private households and businesses in some neighbourhoods of Frick with renewable district heating. The wood-fired boilers will be fuelled with regional wood chips from the Thiersteinberg forestry operation.

    Due to the high demand, IWB is already examining the expansion of the supply area in the Ob em Dorf and Chilmet districts. Both the current and future constructions are associated with a number of traffic restrictions, which will be adapted by the municipality and canton as required. IWB invites you to an open day on the site of the heating centre on 5 April 2025.

  • Lake Biel supplies energy for Nidau and Biel

    Lake Biel supplies energy for Nidau and Biel

    Energieverbund Bielersee AG is supplying energy to customers in Nidau and Biel for the first time, according to a press release. To this end, the intermediate circuit connecting the pumping station on Dr. Schneiderstrasse with the energy centre in the Alpha building in Nidau has been constructed in recent weeks.

    The lake water reaches the pumping station via two pipes at depths of 20 and 30 metres. In the energy centre, heat pumps are used to produce hot water for heating systems that are connected to the heating network. The cold, in turn, is channelled via a separate network to the Robert-Walser-Platz area near Biel railway station. A peak load boiler is available for cold days.

    The plans for the use of lake water date back to 2015. in 2020, Energie Service Biel/Bienne founded Energieverbund Bielersee AG, in which the city and the Burgergemeinde Nidau are now also shareholders. The lake pipelines were laid in March 2022 and the shell of the pumping station was completed the following May. In future, the energy centre is to be renovated and the heating network extended towards Ipsach.

  • Canton of Lucerne increases funding for energy

    Canton of Lucerne increases funding for energy

    The canton of Lucerne is increasing its contribution to the Energy 2022 funding program by CHF 3.5 million compared to the previous year to CHF 5.5 million. Together with the basic amount and the federal supplement, a total of around 23 million francs is available. Private individuals can submit their applications for grants to increase energy efficiency and the use of renewable energy in their own four walls from January 10th.

    As stated in a communication from the canton, the funding program has been checked and optimized after five years of experience. The inclusion of important interest groups was helpful. “Cooperation with the trade, with the various associations and with the university is important so that we can continue the success story of the energy funding program,” said Fabian Peter, the government councilor responsible for construction, the environment and energy.

    The most important changes for the year 2022 include new funding measures such as connection to a heating network with renewable energies, non-automatic wood firing and charging infrastructure for e-mobility in existing apartment buildings. There were also adjustments to the funding rates. Renewals of building insulation are now subsidized with 60 instead of 40 francs per square meter. The subsidy rates for solar thermal systems will be doubled. In addition, there are now flat-rate subsidy rates for building services up to 15 kilowatts, for example for a heat pump, a wood-burning stove or a district heating connection.

  • Primeo Energie is building a new heating center in Allschwil

    Primeo Energie is building a new heating center in Allschwil

    According to a media release , Primeo Energie is building a new underground heating center for the existing heating network between the indoor swimming pool and the music school in Neuallschwil. The foundation stone was officially laid on Wednesday. The system is operated with two wood-burning boilers with an output of 840 kilowatts each. In addition, a heat pump uses the environmental heat and waste heat from the indoor pool. This generates 80 percent of the energy required. The plant will go into operation in early summer 2021.

    "The community and Primeo Energie are setting another example for a renewable, CO2-neutral heating supply", said Nicole Nüssli-Kaiser, President of the City Council. "With this central heating system, we not only heat the school building, but also enable the entire district to rely on renewable thermal energy."

    This new heating center is another piece of the puzzle in the heating network, the message goes on to say. It will be connected by a pipeline to the heating network, which is also primarily fired with wood chips, at the old people's center at Bachgraben. This enabled synergies to be used between the two district heating networks. Further properties are to be connected to the network. By merging several centers, security of supply will also be increased.
