Integrated solar power plants in incentive system
HEP built nine solar power plants on roofs of its office buildings in 2014. The power plants are located on the office buildings at HEP's headquarters in Zagreb and on the buildings of HEP Operator distribucijskog sustava in Čakovec, Šibenik (SS Bilice), Split, Opatija, Zadar, Dubrovnik and on two locations in Osijek. Solar power plants are operated by HEP Proizvodnja.
Individual power of each power plant is up to 30 kW. The total power of power plants is 207 kW, and average annual generation amounts to 240,000 kWh.
Solar power plants have the status of eligible electricity producer, which allows the sale of generated electricity to the Croatian Energy Market Operator at a preferential price.
Integrated solar power plants without incentives
In 2018 Hrvatska elektroprivreda started constructing integrated solar power plants according to the concept of a customer with own generation. That model enables a significant reduction of expenses for own electricity generation. The majority of generated electricity is spent on the plants themselves, whereas the rest of electricity is delivered into the distribution grid.
As of December 31, 2025, the HEP Group had 55 integrated solar power plants built according to this model. A project is currently underway in which an additional 90 photovoltaic power plants will be installed on the roofs of facilities owned by HEP d.d. and used by the companies HEP ODS, HEP Proizvodnja, HEP Toplinarstvo, HEP Plin, and HEP Upravljanje imovinom.
