Where is the largest battery storage system in Switzerland?In Kappel, in the canton of Solothurn, one of the largest battery storage systems in Switzerland is currently under construction, with a total capacity of 65 megawatt-hours. The successful delivery of all system components marks a key milestone on the path to commissioning. Primeo Energie will use our storage system to provide energy flexibility.
Will battery storage improve grid stability in Germany?For the midterm, battery storage will therefore primarily improve grid stability in Germany – at least to the extent that these storage systems are tailored to grid needs and not to the optimization of solar power consumption in households. Younicos is thus focusing on the market for ancillary grid services (frequency response), not arbitrage.
Does Switzerland's new large-scale battery support the Energy Strategy 2050?The new large-scale battery for Switzerland in Kappel supports the Energy Strategy 2050 and supports renewable energies.
How does electricity storage work in Switzerland?Electricity storage is not separately defined in the Swiss legislative framework. The biggest obstacle for electricity companies is to obtain a construction permit and a concession for the operation of a pumped storage plant, which is granted for a maximum of 80 years.
Will large-scale battery storage help stabilize the power grid in 2050?The country is pursuing the goal of transitioning its energy supply entirely to renewable sources by 2050. “Large-scale battery storage systems will play an increasingly important role in stabilizing the power grid in the future.” — Frederik Süllwald, Head of Global Sales & Key Account Management, INTILION.
Which energy storage projects have been commissioned in Switzerland?Axpo commissioned its BESS in February this year while utility Thurplus commissioned a 3MW system in September last year. But Switzerland was the location for one of the largest energy storage projects commissioned in recent years, a 20GWh pumped hydro energy storage (PHES) unit which started operations in June 2022 in the Canton of Vala
