Die Stromfritzen
Your site becomes a power plant

We are Die Stromfritzen and we get more out of your site.

The Stromfritzen circuit

Current only flows in a closed circuit. Ours closes in your region.

Part of every project goes to local non-profit organisations and clubs: from Crossfire Gym in Wismar to ETB Schwarz-Weiß Essen.

Grid fees from 2029

AgNes: grid fees in Germany are being reorganised.

AgNes is the procedure in which the Bundesnetzagentur, Germany’s Federal Network Agency, is restructuring electricity grid fees. According to its current position, the decision is to be adopted in 2026 and apply from 2029. For businesses with higher consumption, the peak load will then carry more weight, and a battery storage system can absorb it.

Cut-off date for storage: Under the German rule § 118 Abs. 6 EnWG (Energy Industry Act), storage systems that go into operation by August 2029 are exempt from grid fees for 20 years. Under the draft, this exemption only remains if the storage system has been firmly ordered before the decision. The planned date for this is 1 January 2027.

It is still a draft. You can already plan for it: we advise you on PV and battery storage.

For municipalities

Charging infra­structure for municipalities

For municipalities, local authorities and special-purpose associations, we plan charging points on public land: at the town hall, the municipal depot, the school, the sports hall or in the car park.

Where the roof allows it, we connect them to a PV system and battery storage. That way the fleet charges with power from its own roof.

Part of every project goes to the region.

Part of every sale flows back into the regions, to non-profit organisations and clubs.

For example to ETB Schwarz-Weiß Essen and to the youth programme at Crossfire Gym Wismar.

Services

Four components. One circuit.

PV project development, storage project development, charging infrastructure and investment in renewable energy all run on one line with us. Tenant electricity and roof refurbishment branch off it when your building needs them. You have one contact person, from your site to the grid connection.

  1. 01

    PV project development

    Your unused roof or open land turns into electricity that lowers your energy costs. We plan the system, build it and take care of the grid connection.

  2. 02

    Storage project development

    At midday the storage system takes in the surplus your roof produces and releases it in the evening or at peak load. We size it to your consumption.

    Charging infra­structure

    We plan charging points for companies, residential complexes, fleets and municipalities and connect them to your PV system and battery storage. That way your vehicle charges with power from your own roof.

    Investment in renewable energy

    You invest directly in a photovoltaic project: transparent, commission-free and with a direct influence on sustainable projects.

Alongside PV project development

Tenant electricity and roof refurbishment

  • Tenant electricity

    Your tenants get solar power straight from your roof. We handle planning, installation and billing.

    More on tenant electricity
  • Roof refurbishment

    If your roof is old or damaged, we refurbish it before the modules go on. Roof and system are then in one pair of hands.

What we build flows back into the region.

Part of every project goes to local non-profit organisations and clubs. That applies to every project, including yours.

11clubs and initiatives in the circuit, each entry with source and date

On one side, systems in three sizes, from large to smaller. On the other, the clubs and initiatives we support, each with a note of where it is publicly documented and since when. Both sides are connected by one rule that applies to every project.

Contact

The circuit is still open. Your project closes it.

Tell us about your roof or open land. We assess it free of charge and get back to you with our view. Part of your project will also go back to the region.

Who do you work for?
For owners of roofs and open land, for companies, investors and housing associations.
Which sites are suitable?
Large roofs, halls, agricultural buildings and vacant plots. We check free of charge whether your site is suitable.
Do I have to pay for the system myself?
No. You can invest yourself, rent or lease out your site, or build together with an investor.
How long does it take until the first power flows?
Usually a few weeks to a few months. It depends on the size of the system and on the permits.
Do you look after it after construction too?
Yes. We take care of maintenance and monitoring of the system after commissioning as well.
Where does the share from my project go?
To local non-profit organisations and clubs: that is our rule for every project. We do not state a fixed amount or percentage for it. You can see which clubs and initiatives we have supported so far in the circuit above, each point with its public source.
