    Energie 360° supplies district heating to Effretikon

    The town of Illnau-Effretikon has concluded a concession agreement with Energie 360° for the construction and operation of a district heating network in Effretikon. According to a press release, the 50-year contract provides for the supply of district heating to around 3,000 households in the Vogelbuck and Watt districts, the industrial area in Bietenholz and the areas to the east and west of Effretikon railway station.

    Energie 360° supplies the district heating via a four-kilometre-long transport pipeline from its energy centre in Volketswil. Construction of the pipeline has already begun. The first deliveries are scheduled for the 2027/28 heating period. Development of the entire area is planned by 2030. Energie 360° is investing an amount in the three-digit million range.

    According to Mayor Marco Nuzzo, the heating network is an important step towards a fossil-free energy supply. “We support a sustainable energy supply because it is a basis for our city’s development strategy,” he is quoted as saying in the press release. Councillor Rosmarie Quadranti adds: “The energy network offers the population of Illnau-Effretikon heat from a local, renewable source.”

  • Energie Ausserschwyz expands district heating

    Energie Ausserschwyz expands district heating

    Energie Ausserschwyz, an energy company based in the canton of Schwyz, has presented expansion plans for the development of district heating networks. According to a press release, the company is expanding the network primarily in the districts of March and Höfe. Energie Ausserschwyz has invested CHF 15 million in the densification and expansion of the local district heating network. The district heating is generated using renewable energies such as biomass and woodchips. The expanded areas include the district heating connections in Galgenen, Lachen, Altendorf and Pfäffikon. In 2024, main lines will be built from Altendorf to the Pfäffikon cantonal school and to the centre of Lachen. In addition, fine distribution will be expanded in the four towns mentioned.

    Due to the intensive fine expansion, there will be delays in the expansion of the district heating network compared to the original plans, according to the press release. The villages of Schübelbach, Buttikon and Reichenburg in the March district will then be connected from 2029. Expansions in the Höfe district are not planned until 2040.

  • Voters approve credit for district heating in Chur

    Voters approve credit for district heating in Chur

    Chur’s energy supplier Energie Wasser Chur(IBC) can massively expand its district heating network. The electorate approved a corresponding municipal proposal by 60.85 per cent. It states that the city will contribute 80 million Swiss francs to the total costs for the expansion of the heating network over a period of twelve years. These costs amount to 314 million francs.

    According to its message to the polls on 12 March, the municipal council supported the proposal with 17 votes in favour and 4 against. Now Chur is supporting the generation project of the IBC, which is an independent institution under public law in the sole ownership of the city, with 60 million francs to increase the endowment capital and in the form of a loan. The city is holding a further CHF 20 million in reserve for any guarantee that may be required.

    In the view of the municipal council, the investment is necessary to ensure the conversion to a renewable heat supply within the city. “At the same time, the loss of the previous added value from the sale of gas can be absorbed and the revenues increased elsewhere,” the message continues. “The money that flows out today for the purchase of oil and gas will remain in the region in the future.”

    According to the information, IBC wants to borrow a total of 160 million Swiss francs from financial institutions. In addition, a contribution of 56 million francs from the federal government and the canton is expected. The company intends to invest 38 million francs of its own funds.

  • Implenia is building district heating tunnels in Hamburg

    Implenia is building district heating tunnels in Hamburg

    Implenia will build a 1.2 kilometer long tunnel for Wärme Hamburg , the construction and real estate company from Opfikon informs in a press release . The tunnel is to connect the north of Hamburg to a new heating network. To do this, it will cross under the Elbe around 2 kilometers west of the Elbe tunnel for the motorway.

    The work is divided into two phases, with the planning phase starting in October. Implenia has now received the order for further planning and construction work from the beginning of 2022, according to the announcement. The total order volume there is estimated at around 75 million francs.

    The work should be completed by the first quarter of 2025. To this end, Implenia will first create diaphragm walls for the start and finish shafts with a depth of up to 42 meters. A tunnel measuring 1.16 kilometers long and around 4.5 meters in diameter is then to be drilled between them and lined with precast concrete elements. Implenia is also responsible for planning and installing the operating technology for the district heating pipeline.

    "We are very pleased that we are able to create this large and complex infrastructure project for our customer Wärme Hamburg", Erwin Scherer, Head of Tunneling at Implenia, is quoted in the press release. "The fact that we are making a contribution to improving the sustainability of heat generation gives us additional motivation, because sustainability is an Implenia corporate value that we will also live by in this project."

  • Aesch gets a sustainable heating network

    Aesch gets a sustainable heating network

    Primeo Energie and the municipality of Aesch are planning to set up “a large and sustainable district heating network”, the energy service provider from Basel informs in a message. It is supposed to supply large parts of the municipality with "renewable wood district heating". The investment required for this is estimated in the communication at CHF 20 million.

    In a first step, the partners want to develop the north of Aesch. After that, the network will gradually cover the remaining areas, according to the announcement. The existing heating networks of Primeo Energie and the community and residents' community in Aesch are to be renewed and merged in the new network.

    The plans also provide for the establishment of a new heating center. It will be built in the Weidenring and, in addition to two boilers, will also have a heat pump, explains Primeo Energie. Wood chips from the Aescher forest and the Angenstein district are mainly used as fuel. The peak load is absorbed by an oil boiler.

    In total, the planned heat generation amounts to around 16 gigawatt hours, writes Primeo Energie. According to the company, the share of renewable energy in heat production will be over 80 percent. In this way, more than 3000 tons of CO2 emissions could be avoided each year.

    The planning application for the association should be submitted by the end of this year. The first heat supplies could be realized at the beginning of the heating period 23/24, writes Primeo Energie. Interested property owners can already set up a connection.

  • Basler Stadtwerke get involved in Energie Ausserschwyz

    Basler Stadtwerke get involved in Energie Ausserschwyz

    Energie Ausserschwyz AG wants to supply renewable heat and electricity for 7,000 households in the villages of Siebnen, Galgenen, Lachen, Altendorf, Pfäffikon and Freienbach in the Schwyz districts of March and Höfe by 2030. To this end, it is currently building a wood-fired thermal power station at its existing Bodenwies energy center in Galgenen. It should be heated with old, residual and forest wood from the region.

    Now, as part of a capital increase, IWB are also joining the shareholders of Energie Ausserschwyz AG. According to a press release , Basler Stadtwerke now holds 20 percent of the capital. The regional energy supplier EW Höfe will remain the main shareholder. Brugg Group AG and Züger Unternehmerungen AG are also involved in the district heating operator.

    IWB sees their participation as a continuation of their previous strategy. "Energie Ausserschwyz focuses on a heat supply from regional, renewable sources", its CEO Claus Schmidt is quoted in the announcement. “IWB can bring its experience from climate-friendly district heating supply to Energie Ausserschwyz and benefits from its strong presence in the Upper Lake Zurich region. IWB had already joined Agro Energie Schwyz AG at the beginning of 2021 , which operates a district heating network in the Schwyz basin.

  • ESB promotes conversion to district heating

    ESB promotes conversion to district heating

    At the beginning of the month, ESB launched a program to promote a connection to heating networks in Biel, the energy company informed in a message . With this, ESB wants to support the Biel climate strategy, it says there. In particular, ESB wants to contribute to the city's goal of becoming climate neutral by 2050.

    Most of the buildings in the city of Biel are currently heated with fossil fuels, writes ESB. Switching to district heating therefore has "high potential for reducing greenhouse gas emissions". In order to reach as many property owners as possible, funding for connection to a district heating network is granted regardless of the current energy source.

    Applicants must meet a number of requirements for a contribution to the connection costs, as explained in the communication. On the one hand, the property in question must be located in the area of the city of Biel and be connected to a heating network that is operated with at least 80 percent renewable energies or waste heat. On the other hand, the heating energy must be drawn from the heating network as soon as it is available. Cold connections are therefore excluded from funding. In the case of a connection also funded by the canton of Bern, the ESB grant will also be reduced by the cantonal grant.

  • Nyon builds district heating network

    Nyon builds district heating network

    Nyoner Stadtwerke and Romande Energie establish the joint venture thermorésÔ Nyon SA. This is to set up a district heating network in the city on Lake Geneva, to which up to 130 buildings can be connected, write the city and the Vaudois energy supplier in a message .

    The network is to be heated to 85 percent with wood chips from the region. Natural gas or biogas should only be used at peak times in winter. The initiators expect a reduction in CO2 emissions of more than 7,000 tons.

    Stadtwerke and Romande Energie are already working together on the EnergeÔ project. This is intended to promote the use of geothermal energy from medium depths. This geothermal energy should also be able to be used in the new district heating network in the future.
