Stadtwerke Judenburg AG runs its charging infrastructure on the ENIO backend
Electric mobility is growing quickly, and with it the demands on the operators of charging infrastructure. What is needed are capable systems, transparent billing, flexible tariff models and business models that carry themselves.
With Stadtwerke Judenburg AG, another Austrian municipal utility has chosen ENIO's backend — and set the course for electric mobility it can scale and build on.
A successful start
Stadtwerke Judenburg AG already operates several hyperchargers in combination with the calibration-compliant ENIO Payment Station. That solution delivers:
- legally sound handling of every charging session
- comfortable payment right at the site
- transparent billing that can be traced
- an experience that works for the customer
One point is particularly efficient: a single Payment Station can serve several charge points at one site. That lowers the investment and makes the site easier to use at the same time.
Roaming without the guesswork
A central benefit is ENIO's extensive roaming network. Customers get access to thousands of charge points in Austria and across Europe — with a clear price structure they can follow.
For the operator that means:
- Maximum interoperability
- Use with practically every common charging card, and therefore maximum accessibility
- No hidden extra costs
- Appeal to national and international electric drivers
Transparent pricing in roaming in particular creates trust — a decisive factor in a competitive market.
Flexible tariffs as a commercial lever
Through the ENIO backend, variable tariffs can be defined by site, by user group or by time of day. That makes it possible to:
- put commercially optimised pricing models in place
- steer utilisation deliberately
- serve different customer segments differently
For variable pricing, Stadtwerke Judenburg AG deliberately relies on the calibration-certified ENIO Payment Station. Customers can charge right there on site — with no additional roaming fees. That offer has been used heavily over the past months.
Additional revenue from the GHG quota
A further commercial advantage comes from settling the GHG quota through ENIO. This year the operator benefits from a payment of more than 9 cents per kilowatt-hour charged. ENIO handles the complete administration on behalf of Stadtwerke Judenburg AG.
Every charging session therefore becomes not only an additional service for the customer but also a further, predictable source of income for the operator.
A basis for new business models
The ENIO backend offers not only efficiency in daily operation but room to grow strategically. Charging parks can be optimised deliberately for high contribution margins. Beyond that, the platform opens up new fields of application:
- Residential buildings
Individual tariffs for owners and tenants with automated billing. - Business parks
Differentiated tariff models for companies, their staff and external users. - Sub-CPO models for neighbouring municipalities
Further municipalities can be integrated easily as sub-operators under the roof of the infrastructure operator.
This is how a municipal utility develops from an infrastructure operator into a regional mobility platform.
A lean organisation with strong IT integration
The team at Stadtwerke Judenburg AG is deliberately lean. That makes a partner who takes operational work off their hands all the more important.
ENIO integrates negotiated special conditions directly into the backend. That cuts administrative effort considerably and frees up capacity inside the utility.
Through the API-based IT integration, staff can build detailed analyses themselves. Both partners are currently working on a direct link into the new customer portal of Stadtwerke Judenburg AG. In future, customers will be able to:
- see their charging sessions in the utility's portal
- follow their billing transparently
- request their own charging cards
The technical basis is a modern microservices architecture with scalable API services — the precondition for lean processes and for whatever comes next.
A model with signal effect for other utilities
The partnership between Stadtwerke Judenburg AG and ENIO shows that operators with limited staff can also build a highly attractive and commercially strong portfolio of charging infrastructure.
Without a large internal administration, what emerges is:
- entrepreneurial independence
- new sources of revenue
- stronger customer loyalty
- strategic flexibility towards the regional energy suppliers

Gilbert Ulrich, Head of Energy Trading at Stadtwerke Judenburg AG, describes the cooperation like this: “In ENIO we have found a partner who fully meets our requirements for modern, economical charging infrastructure built to last. What convinced us above all was the combination of technical stability, flexible tariffs and comprehensive service. We get consistently very positive feedback from our own staff and from our customers. The process is transparent, the system runs reliably and it fits into our existing processes without friction. It was decisive for us to choose a solution that grows with our requirements over the long term. With ENIO we see ourselves very well placed.” |
In short
With ENIO as its backend partner, Stadtwerke Judenburg AG secures a capable, flexible and commercially scalable solution for running its charging infrastructure.
Transparent pricing, strong roaming, variable tariff models, GHG settlement, comprehensive service and full IT integration form the basis for sustained growth in electric mobility.
A clear commitment to innovation, to economics and to securing the region's future.
