Croatia’s power utility Hrvatska Elektroprivreda intends to install 90 solar power plants on its facilities across Croatia.

HEP ESCO, a subsidiary of Hrvatska Elektroprivreda (HEP), has launched a public procurement for the installation of 90 photovoltaic plants under a design-and-build model and on a turnkey basis.

The firm develops, implements, and finances energy efficiency projects based on the ESCO model.

The investment is estimated at EUR 5.3 million, and the deadline for submitting bids is November 3.

HEP ESCO plans to sign a contract with the best bidder within 90 days after selecting it. The deadline for the completion of works will be 18 months, according to the public call.

Five groups of solar power plants

The public call is divided into five geographical groups in Croatia.

Group 1 is for Zagreb and its surroundings. Solar panels would be installed at ten locations, with an estimated investment of EUR 1.2 million. Group 2 covers hydropower plants Zavrlje, Orlovac, Peruća, and Zakučaci in the coastal region of Dalmatia, as well as power distribution facilities. The works in the segment are valued at EUR 770,000, local media reported.

Four cities in the region of Slavonia make up the third group, with 20 locations. Solar panels would be installed for EUR 1.21 million in Virovitica, Požega, Vinkovci, and Vukovar.

HEP has over 50 solar power plants on the rooftops of its buildings and facilities

A total of 15 locations in the areas of Međimurje and Zagorje and the Sisak-Moslavina county, and including hydropower plant Ozalj, all in northwestern Croatia, are in the fourth group. The estimated value is EUR 1.1 million.

The value of the investment in Istria, Primorje, and Gorski Kotar is EUR 1.03 million. It entails the Fužine hydropower plant, Rijeka, Vinodol, and electricity distribution facilities.

Of note, HEP has more than 50 solar power plants on the rooftops of its buildings and facilities.

HEP Proizvodnja, HEP’s power production arm, has 12 PV plants on administrative buildings, thermal power plants and hydropower plants. The total capacity is about 1.5 MW. HEP ODS, the country’s distribution system operator, has another 44 solar power plants with a total capacity of 1.1 MW on its roofs.
