The Energy Strategy foresees an additional 22.6 TWh/yr from renewable energy by 2050. Wind energy should contribute 4.3 TWh/yr to this target (with intermediate goals of 0.3 TWh in 2025 and 1.2 TWh in 2035).
Since the introduction of the FIT in 2009, wind projects with an estimated energy yield of 120.8 GWh are in operation and being supported under the scheme in 2021; additional projects with a potential energy yield of 1,737 GWh have been registered, and 1,507 GWh are on the waiting list. This FIT scheme is now over, and a new scheme based on investment subsidies will support wind energy deployment from 2022 (investment subsidies up to 60%). This scheme has the disadvantage of not covering the market price risks on the long terms, and is, therefore, not appropriate for wind energy projects. This scheme could be interesting for community-owned wind turbines, but the authorisation process for such smaller project has to be defined.
The cost of the FIT is financed by a levy on electricity consumption. The maximum levy is of 23 CHF/ MWh (around 21.2 EUR/MWh; 23.8 USD/MWh) and a fund to support renewable energies in Switzerland is financed. The FIT for newly installed wind turbines in 2021 was between 130 CHF/MWh and 230 CHF/MWh. Wind turbines built on locations 1,700 m above sea level or higher receive an altitude bonus of 25 CHF/MWh (23 EUR/MWh; 25.8 USD/MWh) in addition to the standard retribution. The payment period expands over 15 years. This price is a contract for difference, with the market price being at the very high end of 2021, wind turbine operators under this scheme have to give money back to the fund.
