New large storage system should help stabilize the network
In 2021, CKW and Axpo will install a battery storage system with an output of 6.25 megawatts. As the first such storage facility in Switzerland, it is intended to break load peaks, keep the voltage in the grid and compensate for fluctuations between supply and demand.
CKW and Axpo are responding to the expansion of volatile renewable energies. In 2021 you will be implementing a battery storage system in Rathausen which, according to a CKW announcement , can be used for three different markets at the same time for the first time. On the one hand, the system can provide electricity when it is needed, thereby breaking the peak loads. On the other hand, it should help Swissgrid to keep the voltage in the grid stable. Ultimately, it helps to quickly balance out differences between the supply of electricity and demand at any time.
The system consists of two large batteries, each weighing 50 tons, and each housed in a 12 meter long container. It has an output of 6.25 megawatts. That is enough to supply 15,000 households with electricity for one hour.
The system will be installed from mid-2021 and integrated into CKW's medium-voltage network.
