The Potsdam Energy and Water GmbH intends to develop the use of geothermal heat as part of CHP and iCHP systems. Three heat pump modules are to be operated on the site of the South Power Plant of the Energy and Water Potsdam (Zum Heizwerk 20, 14478 Potsdam). The heat from the heat pumps makes a significant contribution to the decarbonization of the city's heat network. A new building is necessary for accommodating the heat pump modules and their peripheral systems. This so-called energy center is to be divided into three sections: the northern section is where the three heat pump systems will be located, which are to utilize the thermal potential of the brine from deep geothermal drillings. The middle section serves to house the transformer stations. The southern section will provide storage space, which prospectively offers the potential and necessary space for the establishment and operation of an additional heat pump (for utilizing river water). Ammonia is to be used as the refrigerant.

LOT-0001
Deep Geothermal VE 21 Energy Center Building.
Lot 21 includes the construction of three interconnected buildings at the site Zum Heizwerk 20, 14478 Potsdam: T0UNA - Deep Geothermal Building T0UBA - Switchgear Building F1UNA - Warehouse The load-bearing structures are predominantly made of precast concrete parts with in-situ concrete floor slabs. Some areas will be constructed using steel construction with trapezoidal sheet metal roofs. The facades will have a trapezoidal sheet metal cladding on a substructure. The execution requires excavation pits including groundwater control as per the subsoil report. The specialized deep foundation works (pile foundations, excavation enclosures) will be carried out according to separate specifications. Accompanying earthworks and preliminary works, such as excavation of the pits, creating working spaces, cleanliness layers, and backfill, are part of this lot. Concurrent work by other trades (e.g., geothermal drilling and CHP expansion) is taking place at the site. The contractor is to coordinate scheduling overlaps, safety distances, traffic routes, and storage areas with the construction management and the involved companies.
