How much will a typical family pay for electricity in 2027 with Repower?

According to Repower's statement, a family of four with an annual consumption of 4,500 kWh will pay 1,449 francs in 2027, twenty francs less than the current year, with a variation of -1.4%. The figure does not include municipal taxes charged on behalf of the Municipalities.

What changes with the new seasonal Grischunpower rate?

From 2027 the standard product Grischunpower will have higher energy rates in winter and more affordable in summer. The average annual price of energy will remain unchanged: it changes the distribution of costs throughout the year. Families who consume more in summer will benefit from the lowest summer rates; those who concentrate their consumption in winter will see a higher cost in that period.

How does the Optima variable rate work?

Optima is a voluntary tariff introduced by Repower from 1 January 2027. The price of energy and grid use varies by hour: each hour is associated with a green, yellow or red level, defined based on the availability of renewables and grid load. The bands are defined in advance and remain unchanged for one quarter. To use it, you need a smart meter and deferrable loads (e.g. electric car charging, heat pump).

Will Repower invest in the network?

Yes, Repower announced annual investments of between 30 and 40 million francs for the upgrading of the grid, the construction of new transformation stations and the adoption of smart grid technologies, in response to the growth of photovoltaic, heat pumps and electric mobility in the Greys area.

What's new for all Repower customers in Switzerland?

The source does not specify the territorial extension beyond the Grisonese network area. Repower's statement indicates that the reductions and new tariffs apply to its network area, mainly in Graubünden. For confirmations on other areas, a direct feedback with the manager would be necessary.

Operational details

What's changing for families in Graubünden

The reduction of twenty francs per year on a standard consumption of 4,500 kWh is contained — equal to 1.4% — but comes at a time when the cost of living and energy bills remain a sensitive item in the domestic budget throughout Switzerland. For a typical household, the savings amount to about 1.67 francs per month, a figure that alone does not change the structure of spending, but adds to other signs of moderation in energy prices.

It is important to underline a technical detail: the savings indicated refer to Repower's standard Grischunpower supply and do not include municipal taxes. In Graubünden — as in the rest of Switzerland — the final electricity bill consists of the sum of energy, network use, taxes and VAT. The increase in real consumption, a change of category (for example, a change to the Optima tariff) or an increase decided by the individual municipalities can easily cancel or exceed the twenty francs of savings indicated.

Seasonal Differentiation: Opportunity and Attention

The logic of the differentiated tariff is well known: shifting consumption in the summer months, when hydroelectric and solar production is more abundant, is in the best interest of both the customer and the grid. Repower explains this by recalling the greater availability of renewable energy in the summer and the trend of the electricity markets.

For a Grisonese family, the practical question becomes: when is it best to move loads?

Key points

What to do now if you are a Repower customer in Graubünden

The changes will take effect on 1 January 2027, but customers can start preparing in advance by checking three concrete aspects of their supply.

Check your consumption profile

First step: download or request from Repower the details of your monthly consumption over the last two years. With the new seasonal tariff structure, knowing how much energy you consume between December and February compared to June-August becomes crucial to estimating the impact on your 2027 bill. If your consumption is concentrated in winter, get ready for more marked seasonal peaks; if it is spread out, the effect will be neutral on the annual total.

Decide whether Optima is right for you

Second step: assess whether the variable Optima tariff suits your lifestyle. It is especially worthwhile for those who have a smart meter, an electric vehicle, or a heat pump and can shift loads to green hours. It is not suitable for those who have no scheduling flexibility: in that case, the risk is paying for red hours without being able to avoid them. Repower will make the quarterly time bands available in advance, so planning is possible but requires attention.

Check the municipal levies

Third step: remember that the bill also includes municipal levies, which Repower charges on behalf of the municipalities. A possible increase in the municipal multiplier can wipe out the announced twenty-franc saving. Check your municipality's website for the 2027 tariffs as soon as they are published.
