What Ekonerg does

Ekonerg (legal name: EKONERG – Institut za energetiku i zaštitu okoliša d.o.o.) is a Zagreb-based, employee-owned engineering and consulting firm operating since 1992 as the legal successor of the 1953-founded Institute for Electricity Industry. The company delivers interdisciplinary engineering services across energy, environmental protection, atmospheric protection and climate, construction management, municipal infrastructure, and information technology. Core technical capabilities span the full project lifecycle — feasibility studies, design and engineering, construction supervision, and ongoing asset and energy management — supported by three accredited laboratories (testing, calibration, proficiency testing) that the company reports is matched by only one other EU peer.

The firm's product portfolio combines proprietary software and professional services. EKONERG KONZALTING, a wholly-owned subsidiary established via a 2022 spin-off, deploys and supports Enterprise Asset Management systems under a long-standing partnership with Hexagon (formerly Infor EAM), localized across seven Southeast European markets, and operates the National Information System for Energy Management (ISGE) for public-sector buildings, with international implementations in Malaysia, Hungary, Bosnia and Herzegovina, Serbia, Armenia, and Moldova. Additional proprietary offerings include the ENOPUS urban energy optimization model (applied in Zagreb, Sarajevo, Skopje, Karlovac), the Environmental Pollution Registry within the EMEP high-resolution network, and an Integral Information Platform for the Croatian Greenhouse Gas Emission Trading System.

Ekonerg generates revenue primarily through project-based professional services sold via direct enterprise sales and public procurement in Croatia, with growing EU-funded project participation and an active internationalization push into the DACH pharmaceutical and cleanroom segment. Anchor clients include Hrvatska Elektroprivreda (HEP), INA, Pliva, Belupo, Nuclear Power Plant Krško, the LNG Terminal Krk, Rockwool, EL-TO Zagreb, Gradska toplana Karlovac, and the Croatian Ministry of Environment and Energy. The firm holds ISO 9001, 14001, 45001, and 50001 certifications, has earned five international awards (2010–2019) for developing the best Informative Inventory Report among small countries under the LRTAP Convention, and reports zero client churn across thousands of contracts.
