The deal transforms a long-time buyer of struggling assets
For over 30 years, A. Gary Klesch has focused on acquiring underperforming industrial assets, including refineries, mills, and smelters, that previous owners were eager to sell. These ventures often involved companies that had lost value or became a financial burden. Now, with the acquisition of BP’s Gelsenkirchen refinery, Klesch Group has become the second-largest oil refiner in Germany. This purchase adds 265,000 barrels of crude refined per day to the company’s portfolio, a capacity that outpaces the two other refineries Klesch already owns in Heide and Kalundborg.
The acquisition also positions Klesch as the leading shareholder in one of Germany’s most critical crude oil pipeline systems. This move solidifies its influence in the national energy landscape, contributing to the country’s fuel supply for transportation and the chemical industry.
Industry trends and environmental costs drive the sell-off
BP stated it anticipates annual savings of up to $1 billion from the sale of Gelsenkirchen. The transaction highlights a broader trend across the industry. Maintaining aging facilities has become increasingly costly, while environmental regulations have made compliance more expensive. These financial pressures are pushing oil majors to reconsider their refining operations.
Unpredictable incidents can further raise these costs. For example, a fire at Gelsenkirchen recently forced a temporary shutdown of some production units, including those critical for diesel. This reinforces the challenges oil companies face in managing outdated infrastructure. Tibor Fedke, a partner at Noerr law firm, explained that for many major oil companies, it is no longer practical to maintain such assets.
Companies like BP, Shell, and Exxon Mobil have all considered scaling back or selling assets in Europe. Fedke noted that these deals also help companies remove one of their largest sources of carbon emissions from their balance sheets, aligning with environmental goals.
Privately owned buyers and regulatory concerns
Klesch’s acquisition has sparked concerns about energy security in Europe, especially given the current instability in supply chains due to conflicts in Ukraine and the Middle East. As a privately held Malta-based company, Klesch Group is not required to provide regular financial disclosures, unlike publicly traded companies. This lack of transparency could potentially affect how secure the supply chain remains.
Sabrina Schulz, an energy expert at the German Council on Foreign Relations, highlighted how this opacity might lead to supply chain vulnerabilities. In response, the government in Berlin conducted a thorough review of the sale and imposed conditions to ensure energy security. These terms require Klesch to guarantee that the refinery continues to supply fuel to critical infrastructure and maintain operational safeguards.
The Economy Ministry has also reserved the right to monitor Klesch’s operations closely. If any violations occur, the government can revoke the company’s ability to operate in Germany. These measures aim to prevent any disruptions that could impact the region’s energy supply.
Despite initial uncertainty surrounding the sale, local workers and businesses in the region are now more hopeful. The deal provides a sense of stability, especially for companies and communities that depend on the refinery for their operations.
Klesch’s history of challenging environmental and regulatory hurdles has not gone unnoticed. The company previously faced legal action from the German government over a temporary windfall tax on energy companies and later abandoned plans for a green hydrogen plant. These incidents add to the concerns about the company’s approach to sustainability and regulation.
According to Fedke, the new wave of refinery buyers, often including specialty funds or family-owned enterprises, are typically less dependent on Western capital markets and traditional green reporting frameworks. While their independence from public scrutiny might offer operational flexibility, it can also create challenges in terms of transparency and accountability.
These concerns are not new. In 2020, a privately held company was found to have the highest emissions intensity among top fossil fuel producers in the U.S., revealing potential environmental risks. This history has led to worries about the implications of privately owned firms taking over critical energy infrastructure.
The Klesch acquisition of Gelsenkirchen marks a significant shift in the European refining industry. With rising costs, aging facilities, and evolving environmental expectations, the sale reflects a broader realignment of the sector’s priorities.
