Solar Potential Study 

The weather in Hamburg is not always bad

REH published the Solar Potential Study in March 2023. The Cluster Agency prepared the study in cooperation with TU Hamburg and the Hamburg University of Applied Sciences to investigate the feasible solar potential in Hamburg's metropolitan region. The authors distinguished between various building categories such as private homes, apartment blocks, commercial roofs and public buildings. They also investigated the potential of open spaces, agrivoltaics and areas above car parks.

The results confirm that up to 9.4 GWp could be mounted on the most suitable (roof) spaces in Hamburg, which would generate as much as 6.9 TWh of electricity. In purely accounting terms, this is equivalent to approx. two thirds of total electricity consumption in Hamburg. Another section of the study looked at use cases for 13 different building categories in total. It proved that a PV system could be run economically across all of these categories.   Profitability is even higher in the use cases if the growing demand for electricity due to increasing electromobility is taken into account.

Building on the findings of the study, the Ministry of Environment, Climate, Energy and Agriculture (BUKEA) entered into talks with the REH Cluster Agency. The network will support the Free and Hanseatic City of Hamburg in the implementation of a PV strategy going forward. Initially, the focus will be on exploiting the spaces on commercial and logistics facilities. According to the study, the realisable potential in this segment is around 1.9 GWp. The REH Cluster Agency will attend the Intersolar trade fair in Munich for the first time with its own booth in 2024.
