Economiesuisse calculates that the Swiss electricity-reserve programme will add roughly 4 billion CHF to consumer electricity bills over the 20-year period from 2026 to 2046. The estimate was published on 15 August 2026, just days before the Federal Parliament postponed financing for four additional reserve power plants.
Cost estimate and its components
The business association's analysis covers the construction of new gas-fired reserve plants and compensation payments to hydro-reservoir operators. A breakdown published by the Neue Zürcher Zeitung shows the following cost components for the 2026-2046 horizon:
| Component | Estimated cost (CHF) |
|---|---|
| New gas-fired reserve plants (4 units) | 2.3 bn |
| Compensation to hydro-reservoir operators | 1.5 bn |
| Other administrative & operational costs | 0.2 bn |
Combined, these items total the 4 billion CHF figure cited by Economiesuisse. The association stresses that the amount represents the incremental impact on household electricity bills, not the programme's total expenditure.
Political context and funding delay
The reserve programme was introduced by the Federal Council in 2022 under the emergency Electricity Reserve Act (Notstromgesetz). While the first reserve plant, built at a cost of about 0.5 billion CHF, never entered operation, four additional gas-fired plants were slated for construction with a projected total investment of roughly 2.3 billion CHF.
During a parliamentary debate in mid-August 2026, lawmakers voted to postpone funding for these four plants. The decision revives a long-standing debate over the programme's affordability and necessity, especially as the cost estimate now quantifies the burden on consumers.
Implications for households
Swiss households already face high electricity prices. Adding an average of 4 billion CHF to collective bills translates into an extra cost of about 200 CHF per household per year, assuming roughly 10 million residential connections. The figure does not include potential savings from avoided blackouts or the value of maintaining grid stability.
Policy analysts note that the postponement may give the government time to reassess the balance between renewable expansion and reserve capacity. However, without clear financing, the planned gas-fired plants could remain on hold, leaving the reserve programme incomplete.
What comes next?
The Federal Council is expected to present a revised financing plan later this year. Meanwhile, Economiesuisse will continue monitoring the cost impact of the reserve programme, and consumer groups are likely to demand transparency on how any additional charges will be reflected in electricity bills.
