The goal of achieving climate neutrality is a long way off.

In the district of Fürstenfeldbruck, an enormous increase in renewable energies would be necessary - and corresponding investments.

District – Many years ago, the district decided to become climate-neutral.

Part of the plans was to avoid about half of the energy consumption.

This notion must be considered outdated by reality.

On the one hand, this is due to the influx into the region, but also to the fact that more is generally consumed.

77 wind turbines

The Sonnensegler association recently caused a stir when it spoke of 77 wind turbines that would be necessary for the energy transition in the district.

But how did the solar sailors get this number?

"We determined the district's consumption using data from climate protection management, our own surveys and publicly available data on all energy sources," explains Falk-Wilhelm Schulz, CEO of Sonnensegler.

"Then we converted this consumption into the heat, mobility and industry sectors to the power consumption required if everything were provided electrically."

On the basis of this conversion, the heat supply was then excluded below.

It would later make sense to switch to geothermal energy.

The possibility of this arises because there are highly dense supply structures.

"So we assumed that all other households would heat with a heat pump and drive with electric cars and only electricity would be used in industry."

total consumption

From this, a total power consumption was determined.

"In an approximate structure, a further 77 wind turbines and 600 hectares of photovoltaics are then necessary, as well as six geothermal wells with heating networks," says Schulz.

FFB newsletter.)

Of course, the power grids would also have to be massively expanded and storage facilities built.

In this model, the district would only be fully supplied on the balance sheet, but not every quarter of an hour, and it would not yet supply large cities such as Munich.

In figures, the solar sailors are assuming a power requirement of 2.2 billion kilowatt hours.

In addition, there would be a need for geothermal energy, which would be around 650 megawatt hours.

The solar sailors calculate that ten million kilowatt hours of electricity will be generated per wind turbine.

That means: The calculation is based on the new, particularly high wind turbines.

Schulz believes that the photovoltaic target can probably be achieved.

"I don't worry too much about that." But massive efforts are needed for wind power and grid expansion.

The municipal utilities

The Brucker Stadtwerke are also massively involved in the energy transition, but their supply area is not congruent with the district.

Olching, Germering, Puchheim or Gröbenzell are not among them.

One photovoltaic open space system near Kottgeisering has already been completed.

It brings 1.3 megawatts (MW).

Bruck Stadtwerke's plants for a further 5.2 MW are also under construction near Kottgeisering and Windach.

Another 4.0 MW are planned, reports a spokeswoman when asked.

Two wind turbines near Mammendorf and Malching are already running, each with around 3 MW.

Four more wheels are planned at Pfaffenhofen an der Glonn (5.5 MW each) and two at Maisach/Rottbach, each with 5.5 MW.

It is currently estimated that a wind turbine will cost between five and six million euros.

The core statement of the municipal utility: In the next 13 years, an average of five MW of photovoltaics and 3.5 MW of wind power must be put into operation every year in order to achieve the energy transition by the end of 2035.

According to the Stadtwerke, the annual investment costs are currently around 8.3 million euros.

The municipal utilities are optimistic: "We're taking the energy transition into our own hands and will make it by 2035."
