The foundations, the solid construction, the carpentry and roof of the 450 square metres battery building have been erected.
The electrical installation for the lithium-ion storage facility with a capacity of 15MWh will now follow.
More than one kilometre of 20kV medium-voltage cable, as well as over three kilometres of 1kV cable, will be laid.
The construction phase also involves the installation of 180 battery racks each weighing 750kg each.
Commissioning is planned for the beginning of next year.
