OMV's €300M Bulgarian Solar and Storage Bet Comes as Oil Rout Deepens

OMV Petrom approves €300M Gabare solar farm with 600 MWh battery in Bulgaria, its first storage venture. Construction starts soon, first power by 2028. Move comes as OMV shares slide on Iran-US oil deal.

The Vienna-based oil and gas major is making a decisive move into renewable infrastructure even as a geopolitical shock rattles crude markets. OMV Petrom, the Romanian subsidiary in which OMV holds just over 51%, has given the green light to the Gabare project in the Bulgarian region of Byala Slatina. The integrated facility pairs a 415-megawatt solar farm with a massive battery storage system capable of holding around 600 megawatt-hours — OMV Petrom’s first foray into the storage business. Such installations help stabilise grids by balancing supply and demand over time.

The total investment is pegged at €300 million, with roughly a third going directly into battery technology. OMV Petrom is co-developing the shovel-ready project with Enery, each holding a 50% stake. Construction is set to begin shortly, with first power expected in 2028. The partners will fund the project through a mix of internal cash and external debt. Offtake has already been secured under contract: OMV Petrom will purchase half of the electricity output, locking in early revenue streams, though the parent company has not yet disclosed any profit forecasts.

The solar-storage push comes at a turbulent time for OMV’s core business. Shares in the Austrian group slumped to €55.30 following news that the US and Iran had agreed on a framework deal that reopens the strategic Strait of Hormuz and lifts Washington’s naval blockade on Iranian ports. Brent crude tumbled roughly 5% to just under $83 a barrel in response. OMV’s stock later recovered slightly to trade at €55.65, notching a modest daily gain of 0.63%, but the monthly damage is stark: the shares have dropped about 12–13% over the past 30 days. The relative strength index now sits near 32 points, approaching deeply oversold territory. Despite the recent rout, the stock is still up around 15% since the start of the year.

The contrast with the broader Austrian market could hardly be sharper. The ATX benchmark surged 2.6% to a fresh record high, as investors rotated out of energy names and into technology plays. Analysts at Morgan Stanley are already looking ahead to a flood of Iranian oil. They expect the country to restore half its production capacity by September and as much as 80% by December. That additional supply will land on a market where US strategic petroleum reserves have dwindled to 340.3 million barrels — the lowest since July 1983, leaving Washington with little ammunition for further intervention.

The near-term outlook for OMV remains highly volatile. Iranian tankers are already passing through the Gulf of Oman, and the formal signing of the accord is set for Friday in Switzerland. Before that, the Federal Reserve delivers its interest-rate decision on Wednesday. Should cheaper oil ease inflation, the Fed could move faster to loosen monetary policy — a tailwind that might eventually boost energy equities. For now, OMV is building a long-term second pillar: Gabare will not produce headline-grabbing price moves without concrete returns, but it marks a strategic hedge against the unpredictability of the oil market.
