OMV Petrom enters Bulgarian solar power market as partner in one of biggest projects

As part of its decarbonization efforts, Romanian hydrocarbons producer OMV Petrom is strengthening its presence in neighboring Bulgaria. It agreed to buy 50% of the Gabare solar power project, of 400 MW, from its developer Enery Element.

The solar power investment frenzy in most of Southeastern Europe is continuing despite rising curtailments and the frequent occurrence of negative power prices. Major developers and operators are counting on battery storage to gradually close the still widening gap between intraday peak production and consumption in spring and autumn.

Romanian oil and gas company OMV Petrom – a subsidiary of OMV – is acquiring a 50% stake in Bulgarian firm Dunav Solar Plant. It is developing the 400 MW Gabare photovoltaic project in Byala Slatina near Sofia.

Until now, the sole owner was Enery Element, a joint venture between Austrian renewable energy company Enery Development and its Bulgarian partner Element Power Group. The two sides didn’t disclose the amount. They expect to close the transaction later this year, after fulfilling certain conditions.

Partners to invest EUR 200 million in total by production launch in 2027

The solar park is expected to enter commercial operation in 2027. By then, OMV Petrom and Enery plan to invest EUR 200 million, including from external financing. They are targeting their final investment decision before the end of 2025.

Solar trackers will maximize output, which will be equivalent to the consumption of 150,000 domestic households, the Romanian company pointed out. A battery energy storage system (BESS) of up to 600 MWh in capacity is an option for future consideration, OMV Petrom added.

Neel: Natural gas and renewables complement each other

“By investing in one of the largest photovoltaic projects in Bulgaria, we are strengthening our presence on this neighbouring market and are supporting the region’s energy transition. We believe that natural gas and renewables complement each other and play a key role in reducing emissions while ensuring energy stability,” said member of the Executive Board of OMV Petrom Franck Neel, responsible for the Gas and Power division.

He added that the company would also offtake 50% of the generated electricity, through a power purchase agreement (PPA), without revealing further details.

Enery currently generates almost 700 GWh of clean electricity per year from 490 MW in installed capacity. It has 8 GW in the project pipeline in 11 countries.

Permits for PV park secured

The construction permits and the grid connection have already been secured, according to the update. At 400 MW in peak capacity, Apriltsi is the largest solar power plant in the Balkans and Eastern Europe, excluding Turkey.

However, a PV system of 550 MW in Greece is about to be completed.

OMV Petrom is the largest integrated energy producer in Southeastern Europe, with an annual group hydrocarbon production of 40 million barrels of oil equivalent in 2024. In addition, it is expanding in the segments of wind power and photovoltaics, energy storage, alternative fuels including green hydrogen, and chargers for electric vehicles.

OMV earlier expressed interest in renewables in Serbia and Hungary as well

The group has a refining capacity of 4.5 million tons. It operates an 860 MW high-efficiency gas-fired power plant. The group is present in Romania and neighbouring countries through 780 filling stations under the brands OMV and Petrom, of which 93 in Bulgaria.

At the end of last year, Austrian energy giant OMV had a 51.2% stake in OMV Petrom. The Romanian Ministry of Energy controlled 20.7% and pension funds in the country participated with 23.7% in total.

In Bulgaria, OMV Petrom started supplying natural gas to business customers last year. Following the discovery of gas resources in Romania’s Neptun Deep block in the Black Sea, it is now exploring the gas potential in Bulgaria’s Han Asparuh block. In April, the company said it approved an investment budget of EUR 1.6 billion for 2025, or over 20% more than in 2024.

Pparent company OMV, headquartered in Vienna, expressed interest last summer in the wind and solar power potential of Romania, Serbia, Bulgaria and Hungary.
