Electricity Agreement and Energy Security
Summary: The new electricity agreement integrates Switzerland into the European electricity market and strengthens supply security -- particularly during the critical winter months. An ETH study estimates savings of around 50 billion francs by 2050. Swiss hydropower (59.5% of electricity production) gains a central role as storage for the European energy transition. Critics fear restrictions on independent energy policy.
¶ The Advantage
¶ Supply Security in Winter
Switzerland depends on electricity imports during the winter months. Without a contractual arrangement, there is a risk that neighbouring countries may restrict exports in times of crisis. The electricity agreement obliges both sides to keep cross-border interconnectors open even during electricity supply crises [1][5].
The Federal Council confirms [9]:
"With the electricity agreement, Switzerland and the EU commit to keeping cross-border interconnectors open in the interest of functioning markets and supply security, even during electricity supply crises."
¶ Integration into the European Electricity Market
Switzerland has been a European electricity hub for decades, with over 40 cross-border lines and an import capacity of 8,000 megawatts (more than six times the output of the Leibstadt nuclear power plant) [7][10]. Without an electricity agreement, it formally operates as an "island" in the European interconnected grid [1][10]:
- Unplanned transit flows through the Swiss grid
- Higher costs for grid stabilisation
- No voice in European market regulation
The VSE (Association of Swiss Electricity Companies) emphasises: "The better Switzerland is integrated into the European electricity market, the more resilient, secure and affordable its electricity supply will be." [10]
¶ Economic Benefit
An ETH study estimates the savings from the electricity agreement at around 50 billion francs in system costs by 2050 -- equivalent to around 2 billion francs per year [7]:
| Factor | Explanation |
|---|---|
| Optimised electricity trading | Efficient deployment of hydropower capacity in cross-border trade [7] |
| 70% rule | EU countries must make at least 70% of their grid capacity available for trade [8] |
| Grid stabilisation | Lower costs for managing unplanned transit flows [10] |
| Market integration | Participation in EU electricity exchanges and balancing energy platforms [5] |
¶ Hydropower as Switzerland's Trump Card
Swiss hydropower is a strategic advantage in the European context [11]:
| Indicator | Value |
|---|---|
| Share of Swiss electricity production | 59.5% [11] |
| Number of hydropower plants (>300 kW) | 704 [11] |
| Average annual production | 37,350 GWh [11] |
| Pumped storage capacity | 3,517 MW [11] |
| Production capacity (total) | 20 GW [11] |
In the context of the European energy transition (expansion of solar and wind), Swiss hydropower gains importance as a flexible storage facility -- Switzerland is regarded as the "electric battery of Europe" [10][11]:
- Absorbing and storing surplus solar/wind electricity from the EU
- Delivering balancing energy back during peak times (e.g. Nant de Drance pumped storage plant)
- A strategic negotiating position for Switzerland in the European energy market
¶ Impact on Consumers
The electricity agreement lowers the basic supply threshold from 100 MWh to 50 MWh annual consumption [8]:
- Around 20,000 businesses (approx. 6% of consumption points) gain the choice between basic supply and the free market [8]
- Affected electricity volume: under 2 TWh (3% of Swiss end consumption) [8]
- A minimum share of 20% renewable energy in basic supply is maintained [8]
- Households and SMEs up to 50,000 kWh/year can continue to remain in basic supply [7]
¶ The Objections
¶ Independent Energy Policy
Critics argue [2][9]:
- The electricity agreement could restrict Switzerland's scope for energy policy -- for instance regarding subsidies for renewable energy [2]
- Dynamic law adoption in the electricity sector means adopting EU energy market regulation [2]
- Switzerland may have to adapt its electricity market liberalisation to EU requirements [9]
¶ Swiss Finish
The Federal Council has set out Switzerland's scope for implementing the electricity agreement ("Swiss Finish") in response to a parliamentary question [9]. The FDFA overview page further emphasises that Switzerland will continue to decide independently on the conditions for using hydropower [5].
