On Tuesday, January 28, 2025, students of the first semester of the Master's degree program in Electrical Engineering and Information Technology, profile Electrical Power Engineering, visited the EL-TO Zagreb (combined heat and power plant) in the Trešnjevka district of Zagreb. The visit was organized as part of the Power Generation course and was attended by about 40 Croatian and foreign students who learned about all the technical units of the combined heat and power station including separate units for the production of process steam for the pharmaceutical and food industries. The EL-TO Zagreb power plant was commissioned in 1907 (the famous Zagreb Munjara), has been modernized and rebuilt several times with different technologies and is today the key to supplying the western part of Zagreb with thermal energy (it supplies about 300 MWt of heating and process steam). In addition to thermal energy, which is generated in several separate boilers, the electricity generation capacity in two gas turbines is currently 50 MWe. The construction of a new combined-cycle cogeneration unit with an electrical output of 150 MWe and a thermal output of 114 MWt is underway and is scheduled to be commissioned this summer.
Within the power plant we also visited the 110/35 kV TS (the largest GIS facility in Croatia with 16 bays), which was built 3 years ago.
