Unintegrated solar power plants

Solar power plant Kaštelir, 1 MW capacity, located at Sabadin in the municipality of Kaštelir-Labinci in Istria, became the first non-integrated solar power plant in the portfolio of HEP following its acquisition in 2019. Kaštelir solar power plant produced 1.4 million kWh in 2020. It is the only HEP’s incentivized solar power plant.

Solar power plant Kaštelir 2, the second phase of Kaštelir solar power plant, constructed at the same location, has been in regular operation since 2021. This 2 MW power plant will generate 2.9 million kWh. 9,240 photovoltaic modules produced by the Croatian company Solvis from Varaždin has been installed on the surface area of about 40,000 m2. The investment is valued at HRK 15 million.

Solar power plant Vis was put into operation in 2020. This 3.5 MW plant is located on the surface area of 5.5 ha, on the Griževa glavica hill, at altitude of about 250 metres, near Žena glava, around 3.6 kilometres southwest of the town of Vis and around 4.8 kilometres east of Komiža. 11,200 photovoltaic modules with the power of 340 Wp were installed, 5.2 km long medium-voltage cable network constructed and five frequency converters with nominal power of 720 kW mounted, produced by the Croatian company Končar, in cooperation with which HEP has carried out this project. The expected annual electricity output is around 5 million kWh, which is sufficiennt for meeting demand of about 1,600 households. The construction of this solar power plant has provided the island of Vis with its own source of renewable energy and ensured a higher security of electricity supply.  The investment is valued at HRK 31.3 m. The next phase includes the installation of a 1MW/1.44 MWh battery tank next to the solar power plant. This battery tank will be used for the provision of the electric power system balancing services and the maintenance of the island network stability.

Solar power plant Marići has been constructed in the municipality of Žminj in Istria on the surface area of 18,000 m2. It was put into regular operation in May 2021. The annual electricity output of this 1 MW solar power plant will be about 1.2 million kWh. The investment is valued at HRK 9 million. 4,092 photovoltaic modules produced by Solvis have been installed.

Solar power plant Obrovac has been constructed in the former alumina plant on the surface area of 117,137 m2. Its capacity will be 7.35 MW. 27,544 photovoltaic modules produced by Solvis have been installed with the power of 8.7 MWp. Its expected annual electricity output of about 11.3 million kWh will meet demand of over 3,500 households. The investment is valued at HRK 52 million. Solvis panels have been installed. The preparations for connecting the plant onto the grid are currently underway.

Solar power plant Stankovci, 2.5 MW capacity, has been constructed in the Stankovci Industrial Zone in Zadar County on the surface area of 65,217 m2. The expected annual electricity output of 4.6 million kWh is sufficient for the supply of 1,500 households. 9,920 photovoltaic modules produced by Solvis have been installed with the power of 3.27 MWp. The investment is valued at HRK 26.3 million. The preparations for connecting the plant onto the grid are currently underway.

Solar power plant Kosore Jug (Vrlika) represents the completion of the first phase of the planned construction in the southern part of the Kosore Business Zone in the town of Vrlika. This 2.1 MW solar power plant is expected to have the annual electricity output of about 2.9 million kWh. The investment is valued at HRK 11 million. The plant construction has been completed, and the preparations for its connection onto the grid are currently underway.

Solar power plant Cres is being constructed at the location Orlec Trinket east, 2 kilometres north of Orlec on the island of Cres. The project was being developed by Primorje-Gorski Kotar County until the issuance of the location permit. This 6.5 MW solar power plant is expected to have the annual electricity output of around 8.5 million kWh, which corresponds to demand of about 2,500 households. The power plant occupies the surface area of 17 hectares and is divided into thirteen 500 kW segments, with the total of 20,330 Solvis 360W panels. The investment is valued at HRK 41 m.
