One modular platform that integrates and manages electricity, heating and cooling. Engineered, assembled and operated in Austria.
Several pressures are converging on commercial and industrial energy users. JOHANN is engineered to address them together — through one integrated system.
Electricity and grid costs continue to rise, increasing pressure on long-term budgets.
Wider price spreads make energy costs harder to forecast and control.
Grid instability events have roughly doubled since 2022, increasing exposure to disruption.
Solar production peaks in summer, while energy demand is often highest in winter.
The EU Critical Entities Resilience Directive is expanding resilience requirements.
To set the standard for intelligent energy systems — through advanced data analytics, engineering excellence and scalable solutions.
To enable more sustainable and efficient energy use — securing a reliable energy future through integrated systems.
From development and assembly to installation and service, every step is handled by one accountable team.
Energy-data analytics and intelligent software optimise each system for long-term performance and return.
Ongoing monitoring, upgrades and servicing keep every system running at its best for years after handover.
Each line works on its own. Combined into one energy hub, they multiply value through sector coupling.
Battery storage for intelligent electricity management.
Battery storage with an integrated heat pump.
Full multi-energy stack for true seasonal balancing.
A single industrial controller coordinates every line at once.
Real-time remote monitoring enables data-driven optimisation.
Start with one line and expand on the same platform as your needs grow.
The platform pays back on two fronts at once — direct savings on the energy bill, and strategic value beyond it.
We calculate your site’s exact savings and payback based on tariff, PV size, funding route and operational profile — giving you proven numbers to decide with confidence.
With 150+ projects realised, JOHANN supports commercial, industrial, public and residential sites.
Where distributed sites share common goals — standardised, repeatable rollout.
Where resilience and autonomy are central and downtime is unacceptable.
Where operational continuity, process stability and cost control decide the case.
Where owners pursue self-consumption and lasting cost stability.
In the field
Start from the same proven JOHANN platform — then choose the conversation that matches your role.
From initial analysis to decades of service, EEG keeps engineering, delivery and optimisation under one roof.
Your real energy profile is analysed using in-house software tools.
Tailored concept options are engineered around your priorities.
The detailed design and permitting path are developed.
Production, installation, and commissioning are managed by one team.
The system is remotely monitored, optimised, and serviced over the long term.
Your priorities, our engineering expertise.
EEG is building a partner network to extend JOHANN into markets and customer groups we do not serve directly — including residential and agricultural segments. You bring the region and the customer relationship; we bring a proven modular platform and the team that engineers, operates and supports it — system engineering, sizing, commissioning and the long-term service backbone, while you remain the face to your customer.
