Germany – Transformer substation – Planung (ab LPH 4 HOAI) und Bau eines Umspannwerks (110 kV FLSA und 10 kV MS Schaltanlage) in 46395 Bocholt

The contracting authority intends to construct a substation. The building shall include the following facilities and spaces: - a 110 kV FLSA including an operating building with a 10 kV MS switchgear (approx. 31 bays), - a room for the control technology (control room for protection, control cabinets, metering), - charging devices, EB distributions (AC & DC), etc.), a separate room for the battery system, - two rooms for E-coils, - a room for telecommunications (accessible from the outside) and corresponding sanitary facilities as well as - three equipment rooms, - fence system, - foundations for the transformers as well as for the 110 kV FLSA. The new substation is to be connected to the 110 kV grid via a double busbar with H-switching. A complete grounding system/lightning protection system must be erected for the substation. Furthermore, the measurement after completion is also part of the scope of the contractor. The contractor must complete the planning for all plant components (design planning (LPH 3 HOAI) is available). Subsequently, he must assemble the plant components and, in coordination with the contracting authority, test them for proper functioning and put them into operation. The large transformers for the substation have already been ordered by the contracting authority. These will be delivered by the end of 2027. The civil engineering services for the cable route, to which the contractor is to connect the substation, have been tendered by the contracting authority in a separate procurement procedure. These services are not part of the tender in each case. The plant must be completed by the planned delivery date of the large transformers, so that the entire plant is operationally ready by the end of 2027.
