NEC Energy Solutions has completed the installation of an 18MW energy storage system in Switzerland for local company EKZ.
EKZ is using the storage facility for primary frequency reserve to stabilise the grid in response to deviations.
The project is located at an existing substation in Volketswil near Zurich and could also be used for other ancillary services.
It is expected to have a payback of five to seven years.
EKZ storage specialist Marina Gonzalez Vaya 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.”
NEC Energy Solutions chief executive Steve Fludder said: “We are excited to deliver the largest energy storage project in Switzerland.
“As countries modernise their power grids across the world, NEC’s storage solutions enable the transformation to a cleaner, more renewable and more digital electric power system of the future. We value the confidence and trust which EKZ has placed in us.”
