Enhancing supply security in the Altenkirchen district through a new substation named ‘Grube Louise’ in the municipality of Bürdenbach. The substation is equipped with state-of-the-art technology, including a remotely controllable 12 kV EES switchgear. Notably, this project marks the first use of environmentally friendly, fluorine gas-free insulating gas called ‘Clean Air’ within the new facility. Siemens’ innovative and eco-friendly technology is being deployed for the first time in the network area of EAM Netz GmbH, representing a significant step towards a sustainable, fluorine gas-free era. A particular challenge during construction was ensuring
uninterrupted service for customers in the network region while erecting the
new ‘Grube Louise’ substation.
Delivery and installation of a new walk-in switchgear
station (precast concrete station), fully equipped with an 8-field 12 kV ESS
switchgear, NXPLUS C24 (blue GIS) type, rated at 1250 A (including 5
line connections at 630 A, 1 dedicated/ON connection, and 1 2-field
longitudinal coupling). This also includes the delivery of various ancillary
works such as control cabinets, secondary technology expansion, and protective
technology using SIPROTEC 5 protection and control devices from Siemens.
The construction of the substation with an environmentally
friendly blue GIS switchgear is part of EAM’s network development strategy and
a significant contribution to supply security. Particularly due to the energy
transition, the power supply is undergoing a massive transformation with high
dynamics. The increase in electric mobility as part of the transportation
transition, the shift to heat pumps in the heat transition, and the expansion
of renewable energies all contribute to a substantial increase in network
loads.
