  • Central Switzerland’s first alpine solar plant goes online

    Central Switzerland’s first alpine solar plant goes online

    energieUri has connected the first alpine solar plant in Central Switzerland to the grid on the Sidenplangg in the municipality of Spiringen, according to a press release. The plant at an altitude of 1,800 to 2,000 meters is set to generate 12.5 gigawatt hours of electricity per year with a total output of 8 megawatts when fully expanded. Almost half of this will be produced in winter.

    The plant currently supplies 13 percent of the planned electricity. This qualifies it for funding under the Solarexpress program. Work is due to resume in spring and be completed by the end of 2028.

    APV Sidenplangg AG is owned by the Uri-based energy supplier energieUri AG as the initiator and aventron AG, based in Münchenstein BL. “Such power plant projects create and secure highly qualified jobs in the region – be it in the planning, realization or future operation and energy management by energieUri,” says Werner Jauch. CEO of energieUri and Chairman of the Board of Directors of APV Sidenplangg AG, is quoted in the press release.

  • New solar plant boosts renewable energy production in the Alpine region

    New solar plant boosts renewable energy production in the Alpine region

    Swisspower AG has received approval from the canton of Graubünden for the construction of the Alpin Parsenn large-scale photovoltaic plant. According to a government press release, the decision is subject to conditions, although these are not specified.

    Swisspower AG is acting as the overall project manager. It represents Energie Wasser Bern(ewb), Industrielle Werke Basel(IWB) and Elektrizitätswerk Davos AG(EWD).

    The project, which until recently ran under the name Parsenn Solar, was approved by the Davos electorate on December 17, 2023. According to its press release from November 2024, Swisspower expected to receive the cantonal building permit before the end of last year; the ongoing work was fully geared towards the start of construction in summer 2025.

    According to the cantonal government, the solar plant will be built at an altitude of 2,500 meters in the Parsenn ski area, which already has an infrastructure and covers an area of almost 14 hectares. With 1493 module tables, it will produce around 12.1 gigawatt hours of electricity per year. In the earlier announcement, there was still talk of more than 10 gigawatt hours, which will supply around 2,200 four-person households in future. Logistical access will be provided via existing access roads. The use of helicopters and walking excavators for minimally invasive installation is also planned.

    Swisspower, based in Zurich, was founded in 2000 as a joint venture between Swiss municipal and public utilities that supply their areas with electricity, natural gas, heat and drinking water. The alliance is supported by 22 shareholder partners from all over Switzerland.

  • Alpine solar plant for Central Switzerland being built in Spiringen

    Alpine solar plant for Central Switzerland being built in Spiringen

    APV Sidenplangg AG, a partner plant of the Uri-based energy service provider energieUri AG from Altdorf and the green electricity producer aventron AG from Münchenstein BL, are building the first alpine solar plant in Central Switzerland, as detailed in a press release. The plant is located in the Sidenplangg area above the village of Spiringen in the Schächental valley in Uri.

    The alpine photovoltaic plant covers an area of 10.7 hectares at an altitude of 1800 to 2000 metres above sea level. The energy is fed into the grid via an existing transformer station. The plant will have an output of 8 megawatts and will generate 12.5 gigawatt hours of renewable solar power per year from 2029. The investment costs amount to CHF 40 million, of which CHF 31 million will remain in the form of contracts for regional companies in the canton of Uri, according to the press release.

    According to the press release, projects under the national Solar Express Initiative are essential for the security and independence of Switzerland’s electricity supply. Switzerland is particularly dependent on the expansion of its winter electricity production. The altitude and production profile make alpine solar plants such as the one in Spiringen particularly suitable for winter electricity production, as they generate three times as much electricity in the winter months as their counterparts in the lowlands.

    “We are delighted to be realising the first alpine solar plant in Central Switzerland together with our partner energieUri. This project underlines the successful cooperation between the Central Plateau and the mountain cantons as well as the joint commitment to renewable Swiss energy production,” said Dominik Baier, Chairman of the Board of Directors of aventron AG.

  • Axpo implements alpine solar systems with partners

    Axpo implements alpine solar systems with partners

    The large-scale solar system originally initiated by Axpo on the Muttsee dam is becoming the AlpinSolar joint project between Denner, Axpo and IWB . As everyone said in a press release of the same name, the energy suppliers Axpo and IWB will install and commission the largest alpine solar system in Switzerland in the summer. Almost 5,000 solar modules are to produce around 3.3 million kilowatt hours of electricity per year on the south-facing dam. Discounter Denner will take it off for 20 years.

    At 2500 meters above sea level, a lot of renewable energy can be generated even in the winter months. Since the system is installed on an existing dam, it is particularly environmentally friendly. This is another reason why AlpinSolar is “a system that the energy transition needs”.

    Nevertheless, “due to the lack of framework conditions, such systems are hardly economically feasible today”, regrets Axpo CEO Christoph Brand. “Nevertheless, we decided, together with strong partners, to implement this lighthouse project” and “to set an example”. "We see the project as an important contribution to the discussion for the upcoming legislative revisions."

    IWB, the energy supplier for the canton of Basel-Stadt, has a 49 percent share in the project. It goes well with the company, says IWB CEO Claus Schmidt, because "the expansion of electricity production from solar energy also in Switzerland" is part of its own strategy.
