For reasons of increasing capacity and to ensure grid stability for regular airport operations, a new third network is to be set up at Munich Airport. This network is primarily intended to integrate consumers of electromobility and photovoltaic systems. At present, it is assumed that approx. 40 MW will be available for future e-mobility and that photovoltaics will be generated with approx. 50 MW peak.

The planned output is approx. 60 MVA draw. For this purpose, a new substation with two 80 MVA auto-transformers in n-1 configuration is planned on the FMG site.

In principle, the 3rd network is to be operated electrically separately from the existing supply networks 1 and 2. However, emergency couplings shall be provided in the event of failure of existing main networks 1 and 2.

Furthermore, a battery storage system with a 24-hour gross reserve of approx. 200 MWh is to be integrated into the third grid. Whether one central storage system or several decentralised storage systems will be used is currently still being clarified.

The planning services for the new 110/20 kV substation to be built, the battery storage system(s) and the photovoltaic systems to be built will each be put out to tender separately. The required interface engineering for the aforementioned lots is part of the order.

General planning services Object and structural planning for engineering structures (shafts, supply tunnels, culverts, etc.), routing/cable routes, traffic facilities, as well as technical equipment cf. § 53 para. 2 No. 4 HOAI (medium and low voltage systems) and No. 5 HOAI (telecommunications and informatics). Attachments).

The assignment includes the basic determination, preliminary planning and design planning (HOAI service phases 1 to 3). Details of the subject matter of the service can be found in the tender documents (see section I.3).
