NEC Energy Solutions has completed the installation of an 18MW energy storage system in Switzerland. The 18MW/7.5MWh installation is owned and operated by the country’s largest power distribution firm Elektrizitätswerke des Kantons Zürich (EKZ) and being used for primary frequency reserve.
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.
“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.”EKZ storage specialist Marina Gonzalez Vaya said.
“We are excited to deliver the largest energy storage project in Switzerland. As countries modernize their power grids across the world, NEC’s storage solutions enables 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.”NEC Energy Solutions chief executive Steve Fludder said.
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.
