What Elektroinštitut Milan Vidmar does

Elektroinštitut Milan Vidmar (EIMV) is a privately held Slovenian engineering and scientific research institute founded on June 1, 1948, operating from its headquarters at Hajdrihova 2, Ljubljana. The institute is organized into six specialized departments covering power-system planning (OENES), environmental monitoring (OOK), power-system control and operation with smart-grid focus (OVDES), high-voltage equipment and power plants (LVN/OVNE), environmental impacts of power facilities (OVENO), and physical-chemical transformer diagnostics (OFKDT). EIMV employs approximately 80 specialized experts and serves electric power utilities (including Slovenian TSO ELES and distribution operators), the Krško Nuclear Power Plant, national ministries (environment, health), and local municipalities across Slovenia and increasingly through EU research consortia.

The institute's core technology assets are three ISO/IEC 17025-accredited testing laboratories and one ISO/IEC 17020-accredited control body, complemented by proprietary intellectual property including the SCALAR real-time lightning localization system, the GREDOS power-network analysis software package, and the EIMV FlexIS distribution-network flexibility platform launched in March 2025. Testing capabilities span high-voltage AC testing up to 700 kV, impulse voltage to 2400 kV, impulse current to 40 kA, resonance-based cable diagnostics to 400 kV, and full transformer diagnostic chemistry including dissolved gas analysis, HPLC, and degree-of-polymerization testing.

Revenue is generated through professional services contracts with energy utilities, government ministries, and EU-funded research consortia (Horizon 2020, Horizon Europe, EURAD-2), supplemented by income from proprietary product offerings (SCALAR data services, GREDOS licenses, FlexIS) and accreditation-driven testing and inspection services. Multi-year contract structures dominate, with no public pricing disclosed. The institute was under the governance of the Slovenian Academy of Sciences and Arts (SAZU) and currently operates under a new director, Dr. Uroš Kerin, appointed September 1, 2025, following the April 2025 passing of long-standing director Dr. Boris Žitnik.
