Bridging Europe’s energy grid with premium South Korean infrastructure technologies.

We solve critical supply chain bottlenecks, pricing pressures, and lead-time challenges for utility-scale solar, T&D grid, and AI data center projects across the DACH & CEE regions.

Who we are

We do not simply broker equipment. We engineer resilient supply chains.

Headquartered in Austria, we operate as a specialized Supply Chain Orchestrator. We connect European grid infrastructure developers with world-class, premium mid-sized power equipment manufacturers in South Korea.

The rigor of 22+ years in project management. Founded by a certified PMP® with over 22 years of enterprise-level energy systems and powertrain experience, HnJ solutions applies absolute operational discipline to global procurement. We understand that a single delayed component can paralyze a multi-million-euro infrastructure project.

We eliminate that risk.

What we orchestrate

Core business areas

Power & Distribution Transformers

  • Agile Factory Slots — Access to guaranteed manufacturing slots with 1.5 to 2-year delivery windows.
  • Strict Efficiency Compliance — All units fully certified to meet EU Ecodesign Directive Tier 2 requirements.
  • Specialized Engineering — Custom low-noise and compact dry-type transformers built specifically for urban substations and AI data centers.

Switchgear & Gas Insulated Switchgear (GIS)

  • SF6-Free Alternatives — Next-generation Eco-Switchgear using Clean Air/G3 alternative gases to comply with tightening EU climate regulations.
  • Robust Arc Protection — High-level Internal Arc Classification (IAC) testing certified via the international STL framework.

Data Center & Renewable Grid Integration

  • Smart Grid Telemetry — Medium-voltage (MV) and low-voltage (LV) systems equipped with intelligent IEDs supporting IEC 61850 protocols.
  • Power Quality Protection — Equipment engineered to withstand strict EN 50160 grid fluctuations and high-frequency harmonics up to 9 kHz.

    The technical edge

    Our compliance bridge: IEC to VDE

    European Tier 1 manufacturers (ABB, Siemens, Hitachi) are pushing lead times past 48–60 months. While South Korea’s top mid-sized manufacturers possess the capacity to step in, navigating the specialized regulatory wall of the German VDE-AR-N 4110/4120 grid codes can be complex. HnJ solutions serves as your dedicated compliance bridge.

    • IEC-to-VDE delta matching

      We leverage existing world-class KERI/STL type-test reports to isolate and verify country-specific grid requirements.

    • Digital grid simulation

      We manage the conversion of raw factory engineering parameters into validated DIgSILENT PowerFactory simulation models required by local DSOs.

    • Risk-shared orchestration

      We align the engineering capabilities of Korean manufacturers with the exact regulatory demands of European grid authorities.
