Swiss Energy Storage Power Station Project Planning

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 Valais.

How will a large-scale storage system help the Swiss power grid?

In this way, the system will help to stabilise the Swiss power grid. With this large-scale storage system, we are making a decisive contribution to the implementation of Switzerland’s Energy Strategy 2050, which aims to convert 100 per cent of its energy supply to renewable energies by 2050.

Where in Switzerland will Primeo energy install a battery storage system?

In Kappel, in the canton of Solothurn, we will install one of the largest battery storage systems in Switzerland with a total capacity of 65 megawatt hours. Primeo Energie will use the stand-alone storage system to make energy more flexible and store electricity temporarily and withdraw it again when it is needed.

How will Primeo energy contribute to the Swiss energy transition?

We are delighted to be taking a significant step in the Swiss energy transition together with Primeo Energie. In Kappel, in the canton of Solothurn, we will install one of the largest battery storage systems in Switzerland with a total capacity of 65 megawatt hours.

What role does hydropower play in the Swiss electricity system?

Thanks to its flexibility and storage options at multi-ple scales, from milliseconds to seasons, hydropower is the backbone of the Swiss electricity system. Keep-ing its central role would foster the integration of volatile renewable energy resources like photovoltaics and wind.

What is a pumped storage plant (PSP)?

Pumped storage plants (PSP) which allow to store large amounts of electric energy by using surplus energy for pumping and releasing energy in times of high demand. The contributions of the various energy sources and power plant types to the Swiss electricity generation are shown in Figure 1.
