  • Sustainable processes through pinch analysis and heat storage

    Sustainable processes through pinch analysis and heat storage

    Lucerne University of Applied Sciences andArts (HSLU) has developed the PinCH software, which can be used to make industrial processes more energy-efficient and economical. According to a press release from the university, the latest version of PinCH 4.0 can also integrate open-loop heat storage systems. A pinch analysis can be used to systematically show how thermal energy flows need to be coupled in order to achieve high energy efficiency with minimal overall costs (consisting of investment and operating costs).

    PinCH 4.0 has already been used to analyze the production processes of the food manufacturer HACO in Gümligen BE. The analysis showed that the use of hot water steam required for process preparation can be reduced by half with an open-loop heat storage system.

    “If process streams, such as the brewing water in a brewery or the process water at HACO AG, are used directly as a storage medium, heat exchangers and intermediate circuits can be saved”, explains Donald Olsen, Project Manager PinCH Software Development at HSLU, in the press release. “Such an open-loop storage system increases the energy-saving potential, simplifies the system and thus reduces energy and investment costs.”

  • Expansion of the photovoltaic system in Schönenwerd

    Expansion of the photovoltaic system in Schönenwerd

    Fashion Fish is investing in the expansion of solar energy, taking the next step towards greater sustainability. As the Schönenwerd-based outlet for designer items informs in a press release, the expansion of the photovoltaic (PV) system on the roofs of the six-storey former Bally production building includes a further 335 solar modules with an output of 140 kilowatt peak. In total, the area equipped with PV modules has increased by 664 square meters.

    According to the press release, the company has been taking steps towards more sustainable energy use for years. According to Managing Director Robert Meier, heating energy is generated via district heating. Electricity requirements have been covered by PV systems since 2020.

    The installation of the first system on the shed roofs has already achieved high peak outputs. An expansion to the east and west at the beginning of 2024 led to a balance in output throughout the day. By the end of August, energy production had amounted to more than 47 megawatt hours of electricity.

    The aim of the investment is to ensure that the majority of stores cover their energy requirements with solar power. This is also to the benefit of customers, for example through cooling ventilation in the summer months. “Thanks to the measures we have taken, we have been able to drastically reduce Fashion Fish’s CO2 emissions in recent years and offset the energy consumption of our air conditioning and ventilation systems with our own solar power,” Robert Meier is quoted as saying. The decision to expand the plant coincides with the company’s 20th anniversary year.

  • Innovation in CO2 removal

    Innovation in CO2 removal

    The new offer makes CO2 removal tangible for companies and individuals. CO2 is removed from the atmosphere using innovative technologies and stored permanently in Switzerland. These so-called negative emissions play a decisive role in achieving Switzerland’s ambitious climate targets, as set out in the Climate and Innovation Act. This solution offers effective compensation, particularly for companies on the path to net zero whose emissions cannot be completely avoided.

    Sustainable storage of CO2 through biochar
    The company relies on an environmentally friendly process for CO2 removal that uses waste wood in the pyrolysis plant of its subsidiary Bioenergie Frauenfeld. The conversion of the wood produces biochar, which serves as a natural reservoir for CO2. A single tonne of biochar stores around three tons of CO2, which leads to a significant reduction in atmospheric CO2 concentrations. Companies such as Zürcher Kantonalbank are already using this technology to permanently bind part of their CO2 emissions.

    Partners for innovation and scalability
    In addition to biochar, Energie 360° is relying on promising partnerships and start-ups to drive forward the scalability of CO2 removal. With Ucaneo Biotech and Planeteers, they are working on pioneering technologies such as direct CO2 removal and carbon capture. These innovations are expected to deliver cost-effective and large-scale CO2 reduction by 2026, which is essential for achieving climate targets.

    Negative emissions technologies are an essential part of climate policy
    Negative emissions technologies are recognized by scientific and political actors as the key to limiting global warming. The permanent removal of CO2 from the atmosphere is essential in order to limit the global temperature rise to a controllable level. In Switzerland, these technologies play a central role in the Energy Perspectives 2050 and in the Climate and Innovation Act. They are seen as essential instruments for achieving a climate-neutral future by 2050.

  • Energy contract signed for sustainable neighbourhood in Romont

    Energy contract signed for sustainable neighbourhood in Romont

    Granges-Paccot-based energy supplier Groupe E and KAAB have signed an energy contract for the La Maillarde neighbourhood in Romont. According to a press release, the 40-year contract covers the supply and utilisation of internal waste heat, the provision of a microgrid infrastructure and the installation of solar modules. Groupe E will supply energy to the site on behalf of KAAB, which will ensure the operation, maintenance and financing of the systems.

    Heat is supplied via the district heating network of the municipality of Romont. The network managed by Groupe E is mainly fuelled by wood chips from local forestry and waste heat from the roasting systems at the Nespresso plant. A gas-fuelled auxiliary heating system is provided for long periods of cold weather.

    The electrical system is controlled by the neighbourhood’s own microgrid. This is fed by a photovoltaic system with an output of one megawatt. It generates around one gigawatt hour of electricity per year.

    The La Maillarde neighbourhood, which is owned by KAAB, was used by the multinational company Tetra Pak until 2016. From 2025, watch manufacturer Rolex will set up shop there, creating around 250 new jobs in the region. The final La Maillarde project envisages an area of 40,000 square metres. Currently, 19,000 square metres are in use.

  • Electrified company fleet also for employees

    Electrified company fleet also for employees

    The world’s first industrial plant for the production of solar fuels is up and running. In collaboration with Empa, the ETH spin-off developed an innovative material for high-temperature heat storage that enables the plant to operate around the clock – even without sunlight.

    The plant uses the power of the sun to convert CO₂ and water into synthetic fuels such as paraffin, petrol and diesel. This closed CO₂ cycle is a pioneering model that could pave the way for a sustainable energy economy. Particularly impressive is the solar energy source and the fact that operation is also maintained at night thanks to innovative heat storage technology.

    Heat storage at 1200 degrees
    The key to this innovation lies in the plant’s heat storage system. A large array of mirrors concentrates sunlight onto a single point, reaching temperatures of up to 1200 degrees Celsius. This heat drives the chemical process that produces fuels from CO₂ and water. Excess heat is stored in specially developed bricks, which keep the system running even at night.

    The challenge in developing the material was to find bricks that could withstand the extreme temperatures and corrosive water vapour atmosphere. In a two-year project, Empa researchers worked closely with Synhelion to develop a ceramic material that meets the high requirements and can also be produced cost-effectively.

    From research to practice
    For the Empa researchers, it was a unique experience to see their research realised on such a large scale. The material, which was tested in a specially developed high-temperature tube furnace, withstood the extreme conditions and is now installed in the “DAWN” plant. This technological achievement not only offers a sustainable solution for fuel production, but could also play a decisive role in the construction and property industry in the future.

    Looking to the future
    While the “DAWN” plant is already in operation, Synhelion and Empa are planning further steps. From 2025, an even larger plant is to be built in Spain, which will utilise higher temperatures and greater storage capacities to further increase the efficiency of fuel production. This development underlines the potential of renewable energies and shows how innovations can lead the energy and property industry into a sustainable future.

  • EnBW acquires enersis to promote digital twins in the energy sector

    EnBW acquires enersis to promote digital twins in the energy sector

    Energie Baden-Württemberg AG(EnBW) has acquired the two sister companies enersis Suisse AG from Bern and enersis Europe GmbH from Kleinmachnow near Berlin, which specialize in digital twins in the energy sector, according to a press release. EnBW is thus strengthening its own technological and digital expertise, particularly with regard to digitalized distribution grids, so-called smart grids, according to the press release. “We identified smart grids early on as a field of innovation that is of strategic importance to us,” EnBW’s Head of Innovation Jürgen Stein is quoted as saying.

    For such smart grids, enersis offers its customers digital twins as a software-as-a-service solution. EnBW describes this as a central competence within the innovation field of smart grids. This is because such twins make it possible to create a digital image of distribution grids that is fed with various energy data in real time. Distribution grids will face additional challenges in the course of the energy transition if numerous small decentralized generation plants are integrated into the low-voltage grid. “An application like this helps us to expand and operate our infrastructure more intelligently,” says Stein.

    Enersis will continue to operate independently as a wholly-owned subsidiary of EnBW. The parties have agreed not to disclose the purchase price. All enersis employees will be taken over and both locations will be retained. The EnBW and enersis teams will work together over the next few months to ensure a successful integration.

  • New wind turbine planned for Flumserberg

    New wind turbine planned for Flumserberg

    Axpo, headquartered in Baden, is starting initial investigations into a possible wind farm on the Flumserberg in the canton of St. Gallen. It could comprise up to six wind turbines. According to a press release, the energy company will install a wind measuring mast this week. This will be used to collect wind and bat data over the course of a year.

    The data collected will serve as the basis for the next project steps and detailed planning. The local community of Flums-Dorf and the Alpkorporation Mols have given their consent for the erection of the wind measuring mast. The 120 metre high mast will be erected on the Grappenchöpf site, a location that Axpo believes offers promising wind potential.

    The electricity produced from the wind farm would be equivalent to the consumption of over 10,000 households. According to the information provided, it could fill the winter gap, as two thirds of electricity production takes place in winter. As Axpo goes on to explain, a wind farm on the Flumserberg would not only help to reduce CO2 emissions and utilise a sustainable, renewable energy source, but would also provide an economic boost for the region.

  • Five cantons take up the cudgels for wind energy

  • District heating pipeline between Perlen and Cham to be extended

    District heating pipeline between Perlen and Cham to be extended

    The energy supplier WWZ from Zug is further expanding the Ennetsee heating network. According to its press release, the Ennetsee region is to be supplied with waste heat from the waste incineration plant in Perlen via a district heating pipeline. This requires an extension of the district heating pipeline from Rotkreuz to Cham.

    In a further construction phase, the pipeline will be laid in the municipality of Risch in the Holzhäuser Strasse area from October 7. Sewerage work will begin there on September 7. This became necessary, among other things, due to repeated flooding caused by heavy rainfall in the region.

    The district heating pipeline will be pre-stressed during construction. This means that the pipe is installed and welded in a preheated state. This prevents uncontrolled expansion of the pipeline under operating load.

    During the construction work, traffic obstructions such as road closures and detour are to be expected in the area. WWZ expects the district heating pipeline to Cham to be completed and put into operation by fall 2026.

  • Falling electricity prices in 2025

    Falling electricity prices in 2025

    The Swiss Federal Electricity Commission has published its calculations for electricity tariffs in 2025. A typical Swiss household with a consumption of 4,500 kWh will pay 29 centimes per kilowatt hour in the coming year, which corresponds to a reduction of 3.14 cents/kWh compared to 2024. This price reduction will result in an annual saving of 141 francs and reduce the electricity bill to a total of 1,305 francs.

    The reductions affect both grid costs and energy tariffs. While the grid costs for a typical household will fall by 4 per cent from 12.71 cents/kWh to 12.18 cents/kWh, the energy tariffs will fall by 12 per cent to 13.7 cents/kWh. Charges to local authorities (1 Rp./kWh) and the grid surcharge (2.3 Rp./kWh) will remain unchanged. There are signs of similar reductions for small and medium-sized companies.

    Fluctuating prices depending on the grid operator
    Electricity tariffs vary greatly depending on the grid operator. This is mainly due to differences in in-house production and procurement strategies. Some grid operators that focus more on long-term procurement are better able to compensate for short-term price fluctuations, but bear higher costs over longer periods. The differences in energy procurement strategies lead to considerable price differences between the regions.

    Reasons for the price reductions
    The more stable wholesale electricity prices are one of the main reasons for the easing of tariffs. Following the significant price increases in 2023 and 2024, wholesale prices are currently quoted at around EUR 90/MWh, which represents a decrease compared to the previous year’s EUR 150/MWh. This market easing will now have a gradual impact on energy tariffs.

    Another factor is the reduction in costs for the winter reserve. While these were still at 1.2 Rp./kWh in 2024, they will fall to 0.23 Rp./kWh in 2025. The return on capital for the grid, the so-called WACC, has also fallen slightly, which also has a cost-reducing effect.

    Procurement strategies and own production as key
    The tariffs in the basic supply are strongly influenced by the production and procurement portfolio of the energy suppliers. In-house production and the timing of electricity procurement are decisive factors. Grid operators that spread their procurement strategies over longer periods of time are better able to cushion price fluctuations on the wholesale market. The level of in-house production also influences the production costs, which are sometimes lower than market prices.

    However, grid costs remain relatively high due to the high market prices, as they are also affected by electricity price-dependent components such as active power losses and ancillary services (AS). Swissgrid provides these ancillary services for the short-term stability of the system and passes the costs on to the grid operators, who in turn charge them to end consumers.

    Transparency for consumers
    ElCom has published the 2025 electricity tariffs for all municipalities and grid operators. These can now be viewed on the website www.strompreis.elcom.admin.ch and offer consumers the opportunity to compare tariffs and find out about the development of electricity prices.

However, the technology still faces a crucial hurdle – the error-proneness of quantum bits, which are the central building blocks of quantum computers. Google has now reached a significant milestone with its latest success in quantum error correction.

    Researchers at Google’s Quantum Artificial Intelligence Lab have managed to combine 97 error-prone quantum bits into one logical quantum bit that has a significantly lower error rate. This is an important step on the way to error-tolerant quantum computers that could perform complex calculations in the future.

    Challenges of quantum error correction
    The biggest challenge for quantum computers is the high probability of errors during computing operations. In current systems, the probability of error is between 0.01 and 1 per cent, depending on the operation. As quantum computers potentially require thousands of calculation steps, this means that the possibility of errors increases exponentially. Without effective error correction, the advantages of quantum computers would be almost impossible to utilise in practice.

    The Google researchers developed a method in which quantum information is distributed across several quantum bits. Measurement bits ensure the stability of the states without directly changing the information. This redundant approach, which is also used in classical computers, led to the formation of a more robust logical quantum bit.

    A decisive advance – but not yet the goal
    Google was able to achieve a critical error threshold by reducing the error rate of a 97-qubit quantum bit system to half that of a 49-qubit system. This progress is highly rated by experts and can be compared to the groundbreaking results of 2019, when Google demonstrated for the first time that quantum computers can outperform conventional computers in certain tasks.

    Despite this promising development, quantum research still faces huge challenges. The next step is to perform basic computing operations with the stabilised logical quantum bits. In the long term, these stable bits will be used to enable complex and fault-tolerant calculations.

    Fault-tolerant quantum computers and their application
    Although the progress made so far is impressive, there is still a long way to go before quantum computers are able to solve really complicated problems. It is estimated that around 1457 physical quantum bits are needed to achieve an error rate of 1 in 1,000,000 – a minimum requirement for solving simple problems.

    For complex challenges such as breaking modern encryption methods, even thousands of logical quantum bits are required. Therefore, further progress in quantum error correction and more efficient algorithms are urgently needed to reduce the required number of physical quantum bits.

    A clear path ahead
    The current results from Google and other research groups form a solid basis for the development of the quantum computers of the future. While many technical hurdles remain, recent advances are making the goal of a powerful, fault-tolerant quantum computer more tangible. Whether and how the technology will become established in practice remains to be seen, but the outlook is now clearer than ever before.

  • Expansion of electromobility in Switzerland

    Expansion of electromobility in Switzerland

    According to a press release, Swiss Post and the fenaco cooperative are moving ahead with their joint plans for a nationwide electric fast-charging network. A total of 50 locations are planned by mid-2025. The capacity is then to be gradually expanded to 300 locations with 1,500 charging stations.

    Private drivers of electric vehicles and company fleets of electric vehicles will find these charging facilities at post offices, Agrola petrol stations and Landi shops, among others. All of them will use 100 per cent local electricity from renewable energy sources, which can be paid for using common payment methods such as Twint and credit cards or a customer card.

    The goal is to be achieved via the PowerUp joint venture. Both partners each have a 50 per cent share in this. The contracts have been signed and submitted to the competition authorities for approval, according to reports.

    PowerUp’s strength is its immediate proximity to workplaces, shops and leisure facilities. The combination with service offerings ensures a safe and well-maintained charging infrastructure with contact persons on site. PowerUp also offers simple pricing with no hidden costs. The partners see their joint commitment to electromobility as a contribution to the federal government’s electromobility roadmap.

  • New battery storage system for Gossau ensures grid stability

    New battery storage system for Gossau ensures grid stability

    Axpo has installed and commissioned a battery storage facility with a capacity of 2.5 megawatts on the site of the Gossau municipal utility. The municipal utility now has the largest battery storage facility in the region, explained the Aargau-based energy company in a press release. According to the press release, the storage facility is tailored to the specific needs of the municipality of Gossau and the region’s grid topography. The press release does not provide any information on the financial scope of the project.

    Stadtwerke Gossau intends to use the battery storage system to compensate for fluctuations in demand and power peaks. It will also process reactive power and contribute to maintaining the grid voltage in the region. It will also help to stabilise the grid in the region by providing system services for the national grid company Swissgrid.

    The new battery storage system is capable of stand-alone operation and black start. This means that in the event of a power outage, it can autonomously restore the power supply for units connected to island operation. Relevant companies for maintaining the supply to Gossau can take advantage of this. “What was initiated in 2019 with a parliamentary initiative can be demonstrated five years later,” says Claudia Martin, City Councillor and Head of the Supply Security Department of the City of Gossau, in the press release. “An energy storage facility that guarantees Gossau’s security of supply.”

  • District heating network in the canton of Aargau is growing

    District heating network in the canton of Aargau is growing

    Regionalwerke AG Baden(RWB) has acquired the shares of AEW Energie AG in Aarau in Fernwärme Siggenthal AG(FWS), according to an ad hoc announcement. In doing so, RWB intends to expand its commitment to sustainable energy supply in the region. AEW Energie specialises in solar power in the canton of Aargau. The sale price was not disclosed.

    RWB has reportedly been working successfully with FWS for many years. The acquisition of the 27.3 per cent stake in FWS is intended to deepen the partnership. FWS, which is based in Nussbaumen, is stable and financially independent and has developed very positively over the last few years since it was founded. It therefore describes RWB as an ideal partner.

    “The investment in Fernwärme Siggenthal AG fits in perfectly with RWB’s activities in the area of district heating,” Managing Director Michael Sarbach is quoted as saying. “Both companies attach great importance to the further expansion of district heating in the region.” Adrian Hitz, Chairman of the FWS Board of Directors, refers to the good cooperation with RWB to date: “Now that AEW has decided to sell its shares, we are relieved that we already know the future shareholder well, as we have already developed and realised a very good project together with the SIBANO connecting pipeline.” SIBANO is a 3.3 kilometre long district heating transport pipeline from the Turgi waste incineration plant to the Baden Nord heating centre.

  • New energy supplier for Uettligen

    New energy supplier for Uettligen

    CKW has taken over the Uettligen heating network with effect from 27 August 2024. According to a press release, the energy supplier from Central Switzerland, which is part of the Axpo Group, intends to expand its decarbonisation strategy. The plants of the heating network north of Bern will continue to be maintained on behalf of CKW by the previous operator and main shareholder a energie AG from Schüpfen BE. Due to an adjustment in a energie’s strategy and the pending further expansion of the heating network, a buyer for the heating network was reportedly being actively sought.

    The acquisition of the Uettligen heating network joins the existing CKW portfolio of district heating networks such as Schüpfheim LU and Meggen LU. According to the press release, CKW will focus on modernising the plants and expanding the district heating network.

    “CKW is looking forward to the collaboration and is proud to be able to continue and further develop the well-functioning Uettligen district heating network,” said Rafael Mesey, Head of New Energies at CKW. “With CKW AG, we will have a reliable and strong partner for our customers in the heating network in the future,” adds Christian Cappis, the outgoing Chairman of the Board of Directors of the Uettligen heating network.

  • Fire services rely on climate-friendly hydrogenated vegetable oil

    Fire services rely on climate-friendly hydrogenated vegetable oil

    GVZ is testing the use of hydrotreated vegetable oil (HVO) as a fuel for fire engines in a pilot project. “From today, Schutz & Rettung Zürich, the Kloten and Wallisellen fire brigades, the Männedorf-Uetikon fire brigade and the St.Gallen professional fire brigade will be refuelling some of their vehicles with HVO,” GVZ announced in a press release. The five fire brigades are particularly suitable for participating in the project as they have their own refuelling facilities.

    “We would like to thank the five fire services for their participation in this promising project and look forward to the initial results,” said Renato Mathys, Head of Fire Services at GVZ, in the press release. “Our aim is to make a contribution to improving the environmental footprint of fire engines.” GVZ has procured a total of 28,000 litres of HVO for the pilot project. It is also paying the difference between the price of the fossil-free fuel and the current price of diesel.

    According to the press release, hydrogenated vegetable oil has a significantly better carbon footprint than diesel and also scores highly in terms of energy density and storage stability. As the biofuel is produced from used cooking oils and fats, its production is not at the expense of food production. The GVZ cites its uncomplicated use as a further advantage: “Diesel engines do not have to be expensively converted, but can be operated and maintained according to the same plan as when running on diesel fuel.”

  • Energy generation and cooling: façades at the centre of research

    Energy generation and cooling: façades at the centre of research

    HSLU researchers have explored the potential for greenery and solar panels on building façades in the GreenPV project. “While the benefits of PV systems and greenery are already being increasingly utilised on roofs, they have largely not been used on façades to date,” HSLU researcher Silvia Domingo is quoted as saying in a press release issued by the university about the project. However, they could contribute to closing the gap in winter electricity, among other things. This is because “the energy yield of a PV system is higher on a south-facing façade in the winter months than on a roof due to the low angle of inclination of the sun caused by the season”, explains Domingo.

    In addition to their cooling effect, green façades also contribute to biodiversity and the reduction of sound propagation. Air quality is also improved through the binding of pollutants and the production of oxygen. According to the HSLU researchers, greenery and photovoltaics (PV) can be combined well on façades. “PV comes into its own where a high level of energy generation is possible, i.e. on an unshaded façade on the upper floors,” says Domingo. Greenery, on the other hand, should be installed on the lower storeys and in inner courtyards.

    The authors have identified financing and a lack of guidelines and experience as obstacles for building owners. The appearance of a façade completely clad in black solar panels is also not to everyone’s taste. For this reason, the HSLU has already tested alternative colours and textures in another project.

  • Successful drilling of Haute-Sorne geothermal project completed

    Successful drilling of Haute-Sorne geothermal project completed

    A pilot project for deep geothermal energy is underway in Haute-Sorne. The initiators, Geo-Energie Suisse and Geo-Energie Jura, have announced that the first borehole has been drilled. According to a press release, it took less than three months to explore the subsurface at a depth of 4000 meters. The borehole ran completely through the sediments and penetrated deep into the crystalline bedrock.

    This provides geological data on the underground in the Swiss Jura arc between Geneva and Basel. “From a scientific point of view, this is a great opportunity to significantly improve our knowledge of the geology of the Jura. Until now, the deep underground has only been described in such detail at a very localized level at a national level.”

    Strict environmental safety precautions apply to the project. There has been no damage or water ingress during ongoing construction work, and noise pollution has been kept to a minimum.

    In the view of Geo-Energie Suisse and Geo-Energie Jura, this step paves the way for innovative future prospects for a sustainable energy supply. The data will provide geological insights into the use of geothermal energy to generate electricity and heat. The first success was celebrated on August 28, 2024. Employees, operational, technical and scientific partners and political representatives were invited to the event.

    The site is suspended while the data is evaluated and the project progress is planned. Tests in the borehole and a geophysical campaign are scheduled for early 2025. The exploration phase is scheduled until the end of 2025.

  • Building program for energy-efficient renovations records record demand

    Building program for energy-efficient renovations records record demand

    A record year has been reported for the federal and cantonal building program. According to a press release, subsidies amounting to CHF 528 million were paid out in 2023. This is the highest amount since the program was introduced in 2010 and represents an increase of 25 percent compared to the previous year.

    Over their lifespan, the funded measures led to an energy reduction in buildings of 11.2 billion kilowatt hours and 3.4 million tons less CO2 emissions, according to the report.

    The reasons for the increased demand are the topics of energy supply security and energy saving, which continue to be of great importance to the public. As a result of rising energy costs, the cantons have increased their funding budgets and, in some cases, subsidies, thereby creating incentives in the renovation sector.

    It also states that, in addition to disbursements, commitments for subsidies for energy-related measures that will be implemented and paid out over the next five years have almost reached their 2022 peak of CHF 592 million at CHF 587 million.

    Most of this was spent on renovation projects for building services. The subsidy francs will be used to replace 26,500 heating systems over the next few years. CHF 114 million has been earmarked for system renovations.

    In addition to the climate targets, the building program had a positive effect on employment and added value. 3,000 full-time equivalents and 150 million francs in additional domestic added value were generated as a result.

  • Decarbonising the real estate sector requires a new approach

    Decarbonising the real estate sector requires a new approach

    The Stoneweg property investment group is meeting these challenges proactively, in particular through its partnership with Romande Energie. Stoneweg has decided to have solar panels installed on several of its sites in French-speaking and German-speaking Switzerland as part of the contracting process.

    Stoneweg’s energy strategy includes a series of ambitious renovation projects focussing on improving insulation, replacing outdated heating systems and integrating renewable energies. Within the next five years, all of the company’s roofs are to be equipped with photovoltaic systems. This decision is motivated by rising electricity prices and the desire to give tenants access to renewable energy at a discounted price.

    Frédéric Noirot, Director of [glossary_exclude]Asset Management[/glossary_exclude] at Stoneweg, explains the benefits of the project: “Our property portfolio also includes older industrial buildings. The contracting model enables us to install photovoltaic systems on our roofs quickly and without major investment costs. This allows us to invest additional funds in other essential renovation measures. It’s a clear win-win situation.”

    As part of the solar energy contracting programme, Romande Energie takes on the complete installation, planning, [glossary_exclude]financing[/glossary_exclude] and [glossary_exclude]management[/glossary_exclude] of the photovoltaic systems on its customers’ buildings. In addition, the energy not consumed on site is utilised by Romande Energie.

    This [glossary_exclude]model[/glossary_exclude] offers several advantages: It generates additional rental income through the optimised use of available space, improves the ESG rating of the properties and increases their attractiveness by providing solar energy for the tenants.

    The cooperation between Stoneweg and Romande Energie is an impressive illustration of how property owners can increase the value of their properties and contribute to the energy transition at the same time. By using green technologies and establishing strategic partnerships, they can not only fulfil legal requirements and social expectations, but also improve their competitiveness on the market.
