64 MW Stolac Solarni Park PV plant in BiH begins power generation

The 64 MW solar power plant Stolac Solarni Park, located near the city of Stolac in the Herzegovina region of Bosnia and Herzegovina, has been connected to the grid and has begun generating electricity. No further details have been disclosed, but the facility appears to be an extension of Hodovo, the largest photovoltaic plant in the country.

“We are proud to announce the successful grid connection of the Stolac Solarni Park photovoltaic plant in Bosnia and Herzegovina,” China-based solar technology company AIKO said in a statement. Developed by Tibra Pacific, the project has entered full operation and is now supplying clean solar power to the regional grid, according to the statement.

The company hailed Stolac Solarni Park as a major milestone, as AIKO and Tibra Pacific completed the grid connection of Europe’s first utility-scale solar project based on Back Contact technology. AIKO claims to have invented N-Type ABC (All Back Contact) technology.

AIKO disclosed few additional details about the project.

Stolac Solarni Park forms a key part of the largest grid-connected ground-mounted PV installation in BiH to date

With an installed capacity of 64 MW using AIKO modules, Stolac Solarni Park forms a key part of the largest grid-connected ground-mounted PV installation in BiH to date, AIKO noted. Originally launched in 2024, the project adopted AIKO’s innovative Stellar 1N+ ABC modules. The system is built on a fixed-tilt structure with an optimized layout to maximize land use.

According to Robert Brajković, Chairman of Tibra Pacific, the project marks a milestone for renewable energy in BiH.

Brajković: We needed technology that performs not just in labs, but on-site as well

“As the country’s largest operational ground-mounted PV plant, we needed technology that performs not just in labs, but on-site as well. AIKO’s modules delivered 12% more energy output and helped reduce electricity costs by 3% in the first phase, compared to the TOPCon setup. As a result, we transitioned the entire second phase to ABC. Their No.1 efficiency and consistency in real-world conditions set a new benchmark for us,” he said.

AIKO noted that Stolac Solarni Park represents more than a utility-scale project – it is a symbol of regional commitment to clean energy. “By deploying advanced PV technology at scale, the project supports BiH’s energy diversification goals,” the company said.

The two firms did not provide any additional information on the projects.

The largest photovoltaic plant in BiH is Hodovo, with a capacity of 92.5 MW, according to the Independent System Operator in Bosnia and Herzegovina. It is operated by Eco-Wat, a local firm owned by Tibra-Pacific. In December 2021, Eco-Wat said it intended to install a 150 MW solar park near Stolac. It appears the project has now reached its planned capacity.

In the same municipality in May, construction was launched on another solar project, with a capacity of 125 MW.

OMV Petrom, CE Oltenia pick contractors for four solar power plants

Oil and gas company OMV Petrom and coal power utility Complexul Energetic Oltenia (CE Oltenia) have signed design and installation contracts for four solar power plants.

In October 2022, OMV Petrom and Complexul Energetic Oltenia said they would build four photovoltaic parks with a combined capacity of 450 MW at former coal mining locations using European Union funds. The two companies are equal partners in the joint venture, each holding a 50% stake.

Now OMV Petrom announced that the four projects would have a total installed capacity of approximately 550 MW, higher than initially planned.

The capacity increase is a result of innovative solutions maximizing power production capability

The increase is a result of innovative solutions that the contractors proposed, to maximize the power production capability, according to the company.

The design and execution of three of the four photovoltaic parks – Rovinari, Tismana 1, and Tismana 2 – with a combined capacity of around 460 MW, was awarded to a consortium formed by US-based Ameresco and Sunel, reads the press release. The latter is registered in the United Kingdom, but its operational headquarters are in Athens, Greece.

The consortium is already active in the region, and recently it launched construction of a giant solar power plant in Greece.

Girisim Elektrik installed the largest solar power plant in Serbia

Turkish company Girişim Elektrik is in charge of the fourth photovoltaic park, with a capacity of around 90 MW. The site is at the former CE Ișalnița power plant, on its slag deposit.

The latest project in the surrounding region that was completed by the contractor is thelargest solar power plant in Serbia. Girişim also installed one of the first utility-scale solar power plants in the Western Balkans – the 10 MW Oslomej unit in North Macedonia.

Of note, tenders for contractorsattracted investors from China, Turkey, the United States, Germany, and Ukraine.

EUR 400 million investment

OMV Petrom estimates the total investment for the four solar projects at over EUR 400 million, of which approximately 70% is financed through the European Union’s Modernisation Fund.

According to Frank Neel, member of the company’s executive board responsible for gas and power, the new contracts are a firm step in strengthening its position in the renewable power sector.

“Through our Strategy 2030, we aim to be a key player in Romania’s energy transition, with the ambitious target of developing 2.5 GW of capacity, including partnerships, from renewable sources – wind and solar,” he added.

The projects will be built on land owned by CE Oltenia, in the Gorj and Dolj counties.

The generated electricity would be delivered to the national power grid and it is expected to cover the annual electricity consumption equivalent of approximately 410,000 households in Romania, OMV Petrom said.
