6 FAQs about [Swiss Photovoltaics and Energy Storage]
Does Switzerland have enough storage energy capacity?
If storage is forced to empty at the maximum discharging speed ( Fig. 5 ), Switzerland has enough storage energy capacity under current conditions, as long as the PV fraction stays above 0.4. If the storage power is increased up to 12 GW, the required storage capacity will increase by 50% for the highest PV shares.
Are pumped-storage hydropower systems balancing intermittent renewable sources in Switzerland?
Particular attention was given to a detailed representation of the temporal behavior and limitations of the storage and pumped-storage hydropower system, because they would play a central role in balancing the intermittent renewable sources in Switzerland.
How will new solar regulations affect Switzerland's electricity grid?
“The new regulations encourage the temporary storage of solar production peaks, which helps relieve the electricity grids,” said Swissolar. Switzerland installed approximately 1.78 GW of new PV capacity in 2024, according to provisional figures from Swissolar.
What are Switzerland's new energy regulations?
Switzerland is expanding rules for rooftop solar, energy storage, and energy communities to expand self-consumption and ease pressure on the grid. The new regulations, set to take effect in 2026, introduce updated tariffs, encourage battery storage, and allow local electricity trading.
How many solar panels did Switzerland install in 2024?
Switzerland installed approximately 1.78 GW of new PV capacity in 2024, according to provisional figures from Swissolar. This marked an increase from 1.64 GW in 2023 and 1.08 GW in 2022, making 2024 a record year for new installations.
What is the Swiss Federal Act on a secure electricity supply?
The Swiss Federal Council has adopted a second set of ordinances to implement the Federal Act on a Secure Electricity Supply from Renewable Energy Sources. The new regulations, set to take effect on Jan. 1, 2026, cover energy communities and minimum remuneration.
