CONCLUSION
MORE INDEPENDENT FROM THE POWER GRID
23
1.
Reduce electricity consumption, e.g. through a comprehensive conversion to LED lighting�
2.
Promotion of the expansion of own power generation in the tunnel environment
3.
Launch of pilot projects “Industrial batteries in tunnel applications"
4.
Change of the emergency power concept to SMART Grid functionality
