What exactly are the aim rate cuts for 2027?

The reductions announced by aim are: average electricity bill between 6.5% and 7.4%; gas 9.43%; network tariff components 2.6%; overall reduction in the cost of energy by 13%, from 12.51 to 10.88 cents per kWh.

When do the new rates actually go into effect?

The new aim tariffs will take effect on January 1, 2027. Customers will receive the official communication by November 2026; the first bill with the new prices will arrive in the first months of 2027.

How do I calculate my personal savings on my bill?

Take your annual kWh consumption from your 2026 bill. The cost reduction is about 1.63 cents per kWh (from 12.51 to 10.88 cts). Example: 4,000 kWh/year × 1.63 cts = CHF 65.20 net energy component savings, plus network cost savings.

Why does the reduction in the bill (6.5%-7.4%) not correspond to the 13% announced?

13% is the drop in the cost of energy per kWh alone. The average bill drops less (6.5%-7.4%) because it includes fixed network costs and administrative services that do not suffer the same percentage of reduction. This distinction is standard in Swiss tariff releases.

What strategy enabled aim to reduce prices so significantly?

Aim planned energy supplies months in advance and staggered them over time, reducing the risk of purchases at peak prices. Careful management of infrastructure investments has also reduced network costs by 2.6%.

Savings: -13% overall, -6.5%-7.4% energy, -9.43% gas

Aziende Industriali Mendrisio announced on August 26, 2026 a structural reduction in energy rates for 2027. The overall cost decrease amounts to 13% compared to 2026, with the average energy price falling from 12.51 to 10.88 cents per kilowatt-hour. For the average electricity bill, Mendrisiotto customers can count on a reduction between 6.5% and 7.4%, while for gas the reduction is even more substantial: 9.43%.

How AIM achieves these savings

According to the company, the rate reduction is the direct result of an energy supply strategy planned several months in advance. AIM indeed defined in advance a significant portion of its energy portfolio intended for 2027, thus neutralizing the risk of price fluctuations in energy markets. This practice of staggered purchases over time has allowed the company to negotiate better economic conditions and pass the benefit directly to end customers' bills.

The tariff components related to network usage will also undergo a contraction of 2.6%, thanks to balanced planning of infrastructure investments and careful management of operating costs. For gas, the situation is even more favorable: purchases already completed for 2027 confirm a more convenient economic scenario compared to the current year.

Operational details

What changes in the Ticino bill

The 13% reduction in the average cost of energy represents a tangible benefit for Mendrisiotto families. For a typical family that consumes 3,500-4,000 kilowatt hours of electricity per year, the change from 12.51 to 10.88 cents per kWh means a reduction in annual expenditure estimated at between 50 and 90 Swiss francs, depending on consumption. When added to the decline in gas (9.43%), the overall impact on the household energy bill becomes even more significant, especially in the winter months when heating weighs more on the household budget.

The role of tariff strategy in the cost of living

In Switzerland, the cost of energy is a critical component of the cost of living, regularly reported by the Federal Statistical Office (FSO) as one of the main inflation factors for household economies. The reductions announced by aim for Mendrisiotto reflect a more general trend: cantonal and municipal grid operators have progressively adopted multi-year procurement strategies to smooth the impact of energy price volatility on consumers. Understanding how the costo della vita e l'energia nel contesto svizzero evolves helps both residents and border workers plan their family budgets more accurately.

How to Verify Your New Rates

AIM customers in the Mendrisiotto region should check the official AIM website or contact the company directly to receive written confirmation of the new rates for 2027. The new rates will take effect starting January 1, 2027 and will appear in the first bill of the new year. It is advisable to keep a copy of AIM's rate notification to compare it with the bill received in the first months of January and February 2027, verifying that the calculations reflect the announced percentages.

When Will Formal New Rates Be Announced

AIM will communicate the complete details of 2027 rates through official communication sent to both residential and business customers. Typically, Ticino and Swiss grid operators communicate final rates by November of the preceding year, allowing customers time to plan purchases or energy management before the colder months. In AIM's case, the announcement of August 26, 2026 is already an advance notice of the reductions that will be formalized in the following months.

Tools to Understand the Impact on Your Energy Spending

For those who wish to calculate the expected savings on their bill, it is useful to have on hand their annual electricity and gas consumption (shown in the previous year's bill). By multiplying the average monthly consumption by the difference between the 2026 rate (12.51 cts/kWh) and the 2027 rate (10.88 cts/kWh), you get the estimated monthly savings. Concrete example: 300 kWh monthly × 1.63 cts reduction = CHF 4.89 savings per month, or approximately CHF 59 annually.
