The Municipality of Eschenbach operates its own site grid at grid level 5, which supplies a municipal works yard, a gravel plant and pit, a school and others. A significant share of the electricity comes from the municipality’s own solar powered systems and is used within a self-consumption community.
At the municipality’s gravel plant, NRG Solutions AG a representative of Brunstock, in Switzerland, is building a battery storage system with a capacity of 15 MWh. It combines self-consumption optimisation, reduction of load peaks, ideal timing of electricity purchases and participation in the market for ancillary services.
The project is being implemented under a contract model: NRG Solutions covers financing, planning, construction, management, operation and maintenance. The municipality provides the land and receives an annual fee over the planned contract term of 15 years.
Three Brunstock 5 MWh BESS battery containers and one step-up station will be placed in a space-saving two-storey steel structure. The infrastructure will be prepared for EV charging, and a manually activated backup power function will supply selected municipal facilities during power outages. Construction is scheduled to start in February 2027.
