The transformation of the energy system requires a robust grid and close cooperation with partners in Switzerland and across Europe. Swissgrid is therefore pressing ahead with the expansion and modernisation of the transmission grid and regards the electricity agreement with the EU as crucial to security of supply. In the first half of 2026, the Swiss electricity system benefited from lower procurement costs thanks to a new imbalance energy price mechanism.
Swissgrid generated net income of CHF 37.8 million in the first half of 2026 (first half of 2025: CHF 45 million). As at the end of June 2026, total assets amounted to CHF 3 billion (2025: CHF 3.5 billion), while the equity ratio stood at 48 percent (year-end 2025: 42.4 percent). In the first half of the year, Swissgrid invested a total of CHF 164.8 million in the modernisation of the Swiss transmission grid, thereby making a significant contribution to security of supply.
Swissgrid lowered its tariffs for the 2026 financial year, which led to the expected decline in revenue for the first half of the year to CHF 513.8 million (first half of 2025: CHF 795.5 million).
At the same time, Swissgrid reduced its procurement costs by 50 percent to CHF 150.1 million (first half of 2025: CHF 300.2 million). The new imbalance energy price mechanism introduced at the beginning of 2026 made a significant contribution to this decrease. It creates incentives for balance groups to play an active role in stabilising the grid, which means that Swissgrid has to use less control energy. This reduces the cost of the secure operation of the transmission grid while increasing the efficiency of the system as a whole. In addition to the new imbalance energy price mechanism, other measures taken to help cut procurement costs include improved forecasts for photovoltaic generation developed in association with the industry, more widespread adoption of AI-based optimisation methods for control energy use, and the optimisation of control power procurement. Optimised control power procurement alone resulted in savings of CHF 63.9 million.
The energy future needs a robust grid
The electricity system in Switzerland and Europe is undergoing the greatest transformation in its history. The expansion of renewable energy, increasing electrification and digitalisation are fundamentally changing the demands placed on the grid.
The grid must be expanded, modernised and digitised to make sure that it does not stand in the way of the energy future. Faster approval procedures are an essential part of this. Many grid projects currently take years or even decades to complete. That is why Swissgrid supports the «Grid express» bill, which is intended to help implement urgently needed grid infrastructure projects more quickly and to strengthen security of supply in the long term.
Grid stability can only be achieved by working together
Switzerland is closely linked to the European electricity system. This means that a secure supply of electricity and stable grid operation cannot be considered in isolation. Particularly in the winter months, Switzerland will continue to require sufficient import capacity over the coming decades. This was demonstrated once again during the past few relatively mild winters.
From Swissgrid’s point of view, the electricity agreement with the European Union is therefore of vital importance. It will enhance security of supply, give Switzerland access to key European power markets and enable it to have a greater say in relevant developments. In addition, Switzerland will be able to participate in the European control energy platforms, which will enhance grid stability and reduce the cost of control energy.
