Switzerland installs its largest energy storage system
The largest power distribution company in Switzerland has installed the country’s largest energy storage system.
Elektrizitätswerke des Kantons Zürich (EKZ) now owns and operates 18MW/7.5MWh grid storage solution system installed by NEC Energy Solutions.
The energy storage system is located at an existing substation in Volketswil, near Zurich and will be used for primary frequency reserve and ancillary services.
The energy storage system will ensure the reliability of the grid during times when energy demand is high through the storage of electricity when the grid is stable and supply during peak periods.
The system will provide energy equivalent of the daily electricity consumption of 600 average four-person households and is expected to have a payback of 5-7 years.
Marina González Vayá, energy storage specialist at EKZ, said: “Battery storage is a vital part of future energy supply.
“The now-completed storage system contributes to the stability of continental Europe’s power grid.”
The project is part of efforts by EKZ to modernise its grid network and enable the integration of more renewable energy resources.
