    Canton of Zurich wants to make solar systems mandatory on large roofs

    “To ensure a secure electricity supply in Switzerland and to achieve the goal of net-zero greenhouse gas emissions, electricity production from local renewable energies must be rapidly and significantly expanded,” says the State Chancellery of the Canton of Zurich in a press release on a planned partial revision of the Energy Act. Specifically, the canton of Zurich wants to make the installation of solar systems on suitable roofs with an area of 300 square metres or more mandatory. The canton estimates that this would allow around 60 per cent of a total annual potential of 6 terawatt hours of solar power from roofs to be exploited.

    The installation of solar systems on large roofs should be mandatory for both new and existing buildings. Existing buildings may be retrofitted when the roof is renovated, but by 2040 at the latest. The requirement should also only apply “if the solar installation is economical over its entire service life”. The corresponding bill has been submitted for consultation until the end of November.

    In addition to the obligation for solar systems, the partial revision provides for the promotion of technologies for seasonal energy storage. This is to be funded by a subsidy fund managed by the electricity grid operators, which will be financed by a levy of a maximum of 0.5 centimes per kilowatt hour of electricity. Competitive tenders are planned, from which projects with the most winter electricity per subsidised franc will benefit, as well as support for seasonal storage technologies that are still under development.

    Federal Council enacts ordinance amendment to implement the solar offensive

    With the amendments to the Energy Act, Parliament facilitates the approval of large-scale photovoltaic plants and establishes a subsidy for them with a one-time payment of up to 60 percent of the investment costs. These facilitations apply until these new large-scale photovoltaic plants allow a total annual production of a maximum of 2 terawatt hours (TWh) throughout Switzerland. The amendments to the Energy Act are limited until 2025.

    The amendments to the Energy Ordinance, the Energy Promotion Ordinance and the Electricity Supply Ordinance adopted by the Federal Council on 17 March 2023 concern the implementation of Article 71a of the Energy Act (production of additional electricity from large-scale photovoltaic plants). DETEC had conducted a public consultation on this from 5 to 16 December 2022. The Federal Council has now laid down the following principles in the ordinance:

    Expansion threshold 2 TWh: The threshold of 2 TWh is determined by the production of the legally approved projects. The cantons shall report to the Swiss Federal Office of Energy (SFOE) on an ongoing basis on the planned projects and their status from the time of the public invitation to tender to the time of commissioning. The SFOE maintains a publicly accessible and continuously updated list of this information.

    Exclusion of crop rotation areas: Installations on crop rotation areas are excluded from the scope of Article 71a. This prevents these PV systems from competing with food production.

    Building permit: The building permit must be issued by the canton. This requires the consent of the siting municipality and the landowners. As part of the building permit, the canton must also stipulate the conditions regarding dismantling. A permit from the Swiss Federal Inspectorate for Heavy Current Installations or the Swiss Federal Office of Energy is required for the electrical connection. The cantonal licensing authority coordinates with the federal authorities.

    Amount of the one-off payment: An application can be submitted if a legally binding building permit has been issued for the project. The maximum amount of the one-off subsidy is 60 percent of the eligible investment costs. In order to benefit from the subsidy, at least ten percent of the expected production of the entire planned plant or 10 gigawatt hours must be fed into the grid by the end of 2025. The deadline for full commissioning of the plants runs until the end of 2030. For those projects that do not meet these criteria, the normal one-time compensation for photovoltaic plants is available. Grid reinforcements: The Federal Electricity Commission is responsible for approving the remuneration for the necessary grid reinforcements for large-scale photovoltaic plants. These costs are part of the system services of the national grid company Swissgrid.
