Underground Thermal Energy Storages: Optimising the integration of Aquifer Energy Storages in the energy supply system for the German Parliament Buildings, Berlin

Project Goal:  Energy demand, the system components of energy supply systems, and the Aquifer Thermal Energy Systems in particular show different temporal behaviour. In comparison with common energy supply components, the temporal behaviour of ATES is almost steady. This implies conflicts between the optimal operation of the system as a whole and the usually sluggish response of ATES. more

The supply of electric energy, heat and cold to the German Parliament Buildings is provided by a combination of systems which is unique so far.
Heat from cogeneration systems or cold from the environment is made available even at times when no heat or cold is provided directly. This is achieved with seasonal heat and cold storage in aquifers. Both Aquifer Thermal Energy Storage Systems (ATES) are located below the “Platz der Republik” in front of the “Reichstags” building and they have been in operation since 2000.
