What should the energy future look like in dettelbach??

Solar energy is currently booming. Dettelbach’s mayor matthias bielek can also tell you a thing or two about it: "it feels like once a week, but at least once a month", according to the head of the town hall on thursday evening in the energy and environment committee, a possible project sponsor for a free-field photovoltaic plant is available in the town hall. The potential areas are already clear: either they have already been bought or a lease agreement has been reached with the farmer.

How to deal with it, what can the city perhaps do itself, can dettelbach’s citizens also benefit, and what to do in two recent cases? – the committee was asked to find answers to a number of questions, or at least to provide some direction. There were three lectures on the different aspects. New: an appropriate presentation can also be designed from afar – no one has to travel from afar anymore. At least two councillors who are not members of the committee attended the meeting from home on the computer.

Hassfurt is considered a model for many municipalities

"The pipeline to hassfurt is in place", said bielek, introducing the first presentation by norbert zosch, managing director of stadtwerke habfurt. Becoming energy self-sufficient, a distant goal for dettelbach, is something that hassfurt has obviously almost achieved "and is thus a role model for many communities", so bielek. And hassfurt does a lot: 13 wind turbines are operated there alone, there are large photovoltaic systems that produce a lot of electricity, and this must be stored somehow, because the energy is to remain on site.

Large battery storage units and conversion to hydrogen – that’s what the municipal utilities are working on. The hydrogen is fed into the gas pipelines and into a combined heat and power plant, where it is converted back into electricity or heat. In addition to the participation of citizens in the plants, an important aspect is: "you can earn a lot of money with it in the meantime", said zosch, habfurt could not otherwise afford a large swimming pool and an ice rink. The tip for the people of dettelbach: "do it yourself and don’t let others do it for you." what applies to energy cooperatives, for example.

Roland koppel, member of the board of directors of VR-bank kitzingen, explained what a cooperative can look like. Together with the truck kitzingen and the baywa, the bank founded a corresponding cooperative, which developed some successful projects. The city of dettelbach, for example, could get involved and develop projects together with the landowners.

Citizens are to be brought on board

It is clear how the request for a free-field photovoltaic plant in mainsondheim by maxsolar gmbh is to continue. The bank is working with the EGIS energy cooperative, whose goal is to operate appropriate plants and to bring the surrounding citizens on board for this purpose. "The citizen invests in his own system", said EGIS managing director pascal lang. A concept that was so convincing that the administration will now move the project forward. All in all, an 8.8 mwp system is to be built for an investment of just under five million euros, which will be able to supply around 3,000 households with electricity and also contain battery storage.

For smaller projects, such as the remaining space on the roof of the new kindergarten in bibergau/effeldorf, bielek says the city will put out a call for bids for its own concept, for example as a gbr or as a citizens’ association. In the case of larger projects, it will be decided on a case-by-case basis whether the city will take action itself, join a cooperative or leave it to a project developer. The first important thing now is to create a cadastre that identifies suitable areas for solar installations. The aim is to steer the development in the interests of the city as well.

Some applications were not clear

In december of last year, the committee approved guidelines for grants for various environmental measures and made 50,000 euros available for this purpose each year. Now the administration submitted some applications for decision by the committee, which were probably ambiguous.

The heating exchange, the water softening plant or also the insulated house door were rejected. The SC schernau’s floodlighting system is to be converted to LED. However, it is assumed that the association will rather take advantage of the 15 percent association subsidy from the city, which is certainly higher than the 1,000 euros of the environmental program.
