The Department for Power Transmission and Distribution primarily researches various technical aspects of management and planning of the Croatian Electric Utility Company’s transmission and distribution network. The Department’s work extends to include HEP’s regional surrounding. The Department provides expert support to the Ministry of the Economy, Labour and Entrepreneurship and, especially, to the Croatian Energy Regulatory Council in the development of secondary legislation related to electrical energy networks (General Conditions for the Supply of Electricity, Regulation on the Calculation of Network Application Costs, Grid Code etc.).

Within a multitude of the Department’s activities, special emphasis is given to: regional planning of transmission networks in southeast Europe and the impact of UCTE reconnection on HEP’s transmission network; static and dynamic transmission system throughput and the identification and management of technical and operating constraints in transmission; regulation, planning, operation and control of electrical energy networks with a high level of integration of renewable distributed energy sources such as wind power plants.

In addition, the following areas of the Department’s operations are considered significant: planning and development of medium-voltage (MV) and low-voltage (LV) distribution networks based on technical and economic analyses conducted by applying in-house and commercial software; estimation of supply quality in regard to different voltage and currents calculations, statistical analysis of power interruptions and measurements in MV and LV networks; technical and economic analysis of impacts of different equipment installation in distribution networks.

The aforementioned activities certainly have a great impact in increasing the operational security of the Croatian segment of what is a large trans-national European network operating in a market environment. International activities shall present a great professional challenge in regard to the expected opening of a regional electricity market and the resulting demands posed by different players on the market.
