Electricity flows with us

The extra-high-voltage grid forms the backbone of a secure electricity supply. Swissgrid works around the clock to ensure that it runs stably, safely and securely at all times. We operate cost efficiently and with consideration for people and the environment. We are already planning and building the grid of the future and making an important contribution to the energy transition.

The invisible instability in the grid – and why early warning matters

16 April 2026 Blog

The energy transition is fundamentally transforming the electricity system. We explain why new sources of instability often go unnoticed – and why early-warning systems are crucial for security of supply.

40 gigawatts of photovoltaic energy in the system – here’s how to make it possible

30 March 2026 Blog

One in every eight kWh in Switzerland comes from photovoltaics. The Swissgrid white paper outlines measures for achieving 40 GW by 2050: changes to requirements for photovoltaic plants, more market signals and streamlined processes.

Swissgrid will reduce tariffs again in 2027

17 March 2026 Media release

Swissgrid uses the tariffs for the transmission system not only to ensure secure operation, but also to finance the modernisation and expansion of the extra-high-voltage grid. This allows Swissgrid to make an important contribution to safeguarding the supply of electricity in Switzerland.

Eight key points to remember about the Swiss balancing market

5 March 2026 Blog

Electricity can’t be stored in the grid, so the volume of electricity produced must always correspond to the volume consumed in order to keep the system balanced. Swissgrid is responsible for maintaining this balance in Switzerland, thereby guaranteeing safe and stable grid operation at a constant frequency of 50 hertz (Hz). If there is an imbalance in the electricity grid, Swissgrid uses control energy or control power from the Swiss balancing market.
