The idea of establishing the Energy Institute Hrvoje Požar grew towards the end of 1993, with the aim of providing professional support to state institutions and companies operating in the energy sector to implement reform processes. The Institute was founded in 1994 by the decision of the Supervisory Board of the Croatian Power Utility (HEP). Upon founding, the Government of the Republic of Croatia and INA d.d. joined as founders. In 2004, the Institute was transformed into a non profit scientific institution owned by the Republic of Croatia. The Institute’s first headquarters were situated at 37 Vukovarska Street, at HEP’s business premises, and since 2000 it has been headquartered at 163 Savska Street, in a building that was specially renovated and equipped to enable the fulfilment of the Institute’s mission.
