The Energy and Water Potsdam GmbH intends to develop the use of geothermal heat within the framework of CHP and iCHP systems. Three heat pump modules are to be operated on the premises of the Süd power plant of Energy and Water Potsdam (Zum Heizwerk 20, 14478 Potsdam). The heat from heat pumps represents an important contribution to the decarbonization of the city's district heating network. To accommodate the heat pump modules and their peripheral systems, the construction of a new building is necessary. This so-called energy center is to be divided into three sections: the northern section will house the three heat pump systems that are to utilize the heat potential of the brine from deep geothermal drilling. The middle section is for the housing of transformer systems. The southern section will provide storage space, which will prospectively offer the potential and necessary space for the construction and operation of an additional heat pump (for the use of river water). Ammonia is to be used as the refrigerant.

LOT-0001
Deep Geothermal Energy VE 21 Energy Center Building.
Lot 21 includes the construction of three interconnected buildings at the location Zum Heizwerk 20, 14478 Potsdam: T0UNA - Deep Geothermal Building T0UBA - Switchgear Building F1UNA - Warehouse The load-bearing structures are predominantly made of precast concrete elements with in-situ concrete floor slabs. Some areas will be executed in steel construction with trapezoidal sheet roofing. The facades will receive trapezoidal sheet cladding on a substructure. For the execution, excavation pits including groundwater control according to the soil report must be created. The specialist foundation works (pile foundations, pit enclosures) will be carried out according to separate specifications. Accompanying earthworks and preliminary works such as excavation, creation of working spaces, clean layers, and backfilling are part of this lot. Concurrently, other trades (including geothermal drilling and CHP expansion) are taking place at the site. Scheduling overlaps, safety distances, traffic routes, and storage areas are to be coordinated by the contractor in consultation with the construction management and the participating companies.
