Reference project

Stuttgart Airport Goes Green

How does one of Germany’s largest airports become a role model for sustainable energy supply? Stuttgart Airport demonstrates how modern storage technology, smart control, and a green vision can work together. Together with Voltfang, the airport is taking a decisive step toward Net Zero – with a project that could set standards for entire industries.

Project profile: Stuttgart Airport

Benefits for Stuttgart Airport:

Greater use of solar power directl

PV power from the airport – efficiently stored and used.

Smart peak load management

Reduces grid fees through targeted relief during peak times.

Infrastructure for tomorrow

Charging points for trucks directly connected to the storage – future-proof and scalable.

CO₂ reduction immediately measurable

Fewer emissions thanks to the use of requalified electric vehicle batteries.

Implemented use case

The Voltfang battery storage system at Stuttgart Airport serves multiple purposes:
It optimizes self-consumption, caps peak loads, enables energy trading, and ensures a stable power supply – even with highly fluctuating energy demand.

Self-consumption optimization

Independent and sustainable

Peak shaving

Save avoidable costs

Multi-use

In diversity lies strength

Intraday Trading

Every hour counts

Aim of the project

The goal is to make airport operations completely greenhouse gas neutral by 2040 at the latest. The current project marks a crucial milestone — and it’s only the beginning: a tenfold increase in storage capacity to 5.4 MWh is already in the planning stage.

Our customized solution

Our commercial storage solution

Capacity up to

540 kWh

Connected load up to

1 MW – 2 MW

Dimensions

1600 / 2100 / 1535 mm

With its sustainable storage solution, Stuttgart Airport is setting a pioneering standard for the energy supply of transportation and infrastructure projects.
