A share in an ewz solar power plant in the canton of Grisons entitles you to purchase environmentally friendly solar power for 20 years. The price per square metre is CHF 560. In turn, we credit you with 180 kWh of solar power per square metre per year.
Solar power protects the environment. Because production is low-emission and consumes hardly any resources, you make a concrete contribution to the energy transition by participating in a solar power plant in the canton of Grisons.
A share in a solar power plant makes you less exposed to electricity price fluctuations.
No problem: If you move away from the ewz supply area, we’ll buy your solar panels back at no loss to you.
- Private households can purchase a share in a solar power plant in the canton of Grisons.
- Check the available plants and select one.
- Register with your name and address, your customer number or your order code.
- Select the number of square metres (min. 0.5 square metres, max. 5 square metres) to be included in your share.
- We credit you with 180 kWh of solar power per square metre per year at the theoretical price of CHF 0.1563/kWh.
- Your annual electricity consumption must not be lower than the credit of the participation.
- In the event of a move, we will buy back your share at no loss to you.
As the operator of numerous solar power plants in our supply area, we have decades of experience in the production of solar power. Thanks to our expertise, we are the ideal partner for you as a tenant when it comes to supplying your household with environmentally friendly solar power.
There is great interest in this type of sustainable energy: the investment model of ewz.solargrischun, in which tenants can participate in a solar power plant, has proved to be a successful model. After a first pilot project in 2018, we decided to build the first high-alpine solar power plant at the Albigna dam in Bergell. The location in the mountains ensures better yields, and electricity production is more efficient due to the cold (albedo effect).
More efficient thanks to the albedo effect
Installing a photovoltaic system in the Alpine region was a daring move. However, as the results of a pilot project in May 2018 exceeded expectations, the decision was made to build the first high-alpine solar power plant on the Albigna dam. Once completed, the plant will generate around 500 megawatt hours of solar power per year. That's an increase in yield of 25% in comparison to a plant of the same size in the lowlands. This is due to the better solar radiation, the cooler temperatures and the reflection of the solar energy by the water in the Albigna lake, as well as the snow that often remains at this altitude until the summer. This phenomenon is known as the "albedo effect". In climatology, it's considered to be partly responsible for global warming.
