Energie Haus GmbH provides vendor-neutral BESS consulting, transformer sourcing, and end-to-end project support for industrial clients, developers, and utilities across Europe. No manufacturing bias. No compromise on quality.
Energie Haus GmbH is an independent energy consulting company and IPS contractor, headquartered in Vienna. We provide unbiased technical advice and access to certified European manufacturers — without vendor lock-in.
We act as your independent technical advisor — from initial feasibility through to delivered solution. Our role is to reduce your risk, not sell you a product.
Feasibility studies, system sizing, and technology selection for BESS and transformer projects. We advise based on your requirements — not on inventory we need to move.
BESS & Transformer Consulting →We work with a curated network of certified European manufacturers — ASTOR, BEZ, and IPS/EXERON. Each partner is pre-qualified on certifications, quality, and reliability.
Our Partner Network →From technical due diligence and supplier selection through to contract management and delivery coordination. We become your single point of contact and take full accountability.
Project Experience →We guide clients through every stage of a battery energy storage project — from initial feasibility through to commissioned system.
We source, validate, and support the integration of distribution transformers from certified European manufacturers — matching your technical specs and delivery schedule.
We are not tied to any manufacturer. We recommend the solution that fits your project — not the one with the highest margin.
We understand the technology. From IEC standards to grid compatibility requirements, we navigate technical complexity so you don't have to.
Access to ASTOR, BEZ, and IPS/EXERON — manufacturers with decades of experience, international deployments, and full certification portfolios.
We manage the full chain — from technical assessment and supplier negotiation to logistics and delivery. One contact. Full accountability.
