The new highly efficient combined-cycle cogeneration unit EL-TO Zagreb CCPP, with electrical output of 150 MWe and heat output of 114 MWt will be a pillar of reliable electricity and heat supply of the City of Zagreb. This is particularly important in times of serious disturbances in the electric power system since electricity and heat supply interruptions in the City of Zagreb will be kept to a minimum.  
During project development HEP took into account the fact that uninterrupted production of heat and process steam at the EL-TO Zagreb site must be secured for the needs of heat and process steam consumers in the western part of the City of Zagreb after 1 January 2018,  when Croatia was required to apply the provisions of the EU Industrial Emissions Directive.

In accordance with the energy efficiency guidelines, which are an integral part of the strategic energy documents of the EU and the Republic of Croatia, HEP is building a new combined-cycle cogeneration unit with exceptionally high primary energy savings, which will replace part of worn-out and obsolete units at the EL-TO Zagreb site.
Since this heat-generating facility will be fuelled solely by gas, this means that significantly less specific CO2 emissions per kWh of energy produced will be generated compared to the present situation at the site. 


Project status

The project is ready for implementation - loan agreements with the European Bank for Reconstruction and Development (EBRD) and the European Investment Bank (EIB) were signed and the Construction Contract and the Long Term Maintenance Agreement with FATA S.p.A. concluded. Main works on the construction of the energy producing facility started in December 2019.
