Nuremberg wants to use municipal roofs for PV

In Nuremberg, a lot of green electricity is to be produced on the roofs of municipal buildings. This was announced by the city and N-Ergie.

In the next ten years, solar plants with a total capacity of up to 15 MW are to be built as part of an expansion plan. That would be enough to supply about 4,300 households.

The goal of the photovoltaic expansion plan presented on July 31 is to install solar systems on as many city roofs as possible and thus significantly increase the generation of renewable energy in the city area. This was preceded by a corresponding city council resolution in October 2022.

According to the project partners, initial investigations have shown that around 350 urban roofs have the potential to install a PV system. Since the roofs must meet certain criteria, they are now gradually being structurally tested. Factors such as orientation and shading also play a role in suitability.

Four projects are already concretely planned. These include PV systems on the roofs of Fire Station 1, the Marktamt administration building, the Taekwondo hall on Bertold-Brecht-Strasse and the Thoner Espan elementary school gymnasium. The plant on the fire station is to go already in the autumn into enterprise

"Already today we co-operate with the N-Ergie in the energy turnaround closely. Be it in the context of municipal heat planning, in the expansion of district heating or the decarbonization of heat generation. Now we are adding a new piece to the puzzle," explained Mayor Marcus König about the plans. He added that a large municipal PV generation park could grow from many small photovoltaic systems in the coming years.

"The expansion of renewable energies is an important part of our strategy. We are focusing primarily on wind energy and on large ground-mounted photovoltaic plants in the region. In the future, however, we will also make the best possible use of suitable city-owned roof surfaces by covering them with many smaller PV systems, thus increasing the share of renewably generated electricity in the city area," explains Maik Render, spokesman for the Board of Management at N-Ergie.
