Your company runs production lines every day, drives cars and trucks, or maintains facilities that operate without a break. The answer to the question above is probably yes. Energy is not your secondary cost. It is a prerequisite for every hour of work.
Your company uses energy every day. The CNC machine, the paint shop, the truck on its way to the customer, the sales agent's vehicle, the heating and/or cooling system. Every energy supplier invoice. Every kilowatt-hour. You know the energy cost in euros. What most companies do not know yet is exactly what are the "hot spots".
In December 2025, Croatia brought an important change in law. The Energy Efficiency Act NN 155/2025 entered into force, and the deadline for conducting the first Energy Audit is 11 October 2026. We understand that keeping up with new regulations is very demanding alongside all other business obligations. That is exactly why we are here.
It is good to know that the obligation no longer depends on the size of the company under the Accounting Act. It depends exclusively on the average annual energy consumption over the last three years.
If your company consumes on average more than 2.78 GWh per year, you are required to conduct an Energy Audit every four years and publicly publish an action plan every 12 months. If the energy consumption exceeds 23.61 GWh, the law requires the introduction of a certified energy management system, e.g. ISO 50001 standard. In the calculation are included electricity, natural gas, LPG, steam and fuel for transport. All processes and all business activities of all affiliated companies without exception are taken into account.
Companies that start preparations now have enough time for thoughtful analysis and strategic decisions based on real data. An Energy Audit is not just a legal obligation. It is a structured insight into which business activity consumes the most energy, what is essential for operations, and where there is room for savings without impact on production.
My name is Ana Radovčić, founder of Net.studio Aranea d.o.o. As an Energy Consultant I help companies understand their energy consumption, conduct Energy Audits, prepare annual action plans and advise on the steps for successful ISO 50001 implementation for companies in their desire to meet legal obligations and keep on making better business decisions.
Add me to your energy team before the deadlines pass.
