DstLg. Todendorf - General Planning Services

The electrical energy supply systems of the Todendorf Bundeswehr facility are to be renewed. The IPU has been established and qualitatively reviewed. A general planning office is sought for the establishment of the FPU. The tasks essentially cover cost groups 440 (medium and low voltage systems), 450 (telecommunications and information technology systems), and 480 (building automation). For the preparation of the transformer station buildings and the locations of the main distribution boards to be replaced in the buildings, parts of cost group 300 are included. For cable and pipeline routes as well as empty conduits and pulling shafts, the planning services of cost group 500 must also be provided. Currently, the electrical connection to the public grid is via a 20 kV medium-voltage connection from Schleswig-Holstein Netz GmbH. The facility has 15 customer-owned transformer stations that supply all buildings on the premises via low-voltage connections. The dilapidated power grid of the facility is to be renewed. The current grid connection capacity of 947 kVA is sufficient. The cables in the medium-voltage network are mostly old and defective. Some sections have already been renewed and should be used further if possible. The medium-voltage network with the transformer stations must be designed for future power requirements. The majority of the transformer stations are to be renewed. The facility will be massively expanded in the near future. Various new construction and renovation measures are planned. A power balance must be established. Data collection is necessary for the creation of the power balance. The actual required power or energy demands must be determined and documented for each building. The same applies to all main low-voltage lines into the buildings and the medium-voltage cables. The documentation should preferably be created in a tabular format in a register and in parallel as an overview in site plans. The upcoming photovoltaic systems, the combined heat and power plant, and the charging stations for e-mobility must be considered. Since a massive increase in power demand is expected due to the upcoming new construction and renovation measures, the new transformer stations must be repositioned according to the load centers. The load extremes for power consumption as well as for generated power from the PV generators must be taken into account. The central heat supply represents a prominent new load center. The development process of the new central heat supply system, which is taking place almost in parallel with this measure, is also crucial for the overall electrical power balance, as the requirements according to the GEG are to be met by means of heat pumps. The maximum available grid connection energy is likely to be exceeded. The preliminary determination of PV potentials also indicates a need to reinforce the facility's grid connection. The necessity of an expansion must be determined at the initial stage of this measure and prepared for separate commissioning. The new cable cross-sections must be calculated and dimensioned according to the increased energy consumption, the planned expansion of renewable energies, and the required charging infrastructure for electromobility, so that the energy supply and distribution are permanently ensured. The expansion of e-mobility must be coordinated separately with BImA as the client. The PV generators and the combined heat and power plant are to feed into the grid operator's network via an EZA controller. The entire system must be certified for feeding into the grid operator's network. The buildings of the facility are to be supplied with new low-voltage connections from the transformer stations via the new medium-voltage network. The old main low-voltage cables into the buildings must also be replaced due to age. The building-side low-voltage connection is made at the main distribution board of each building. Outdated...
