Naturgy scrambles to replace €2 billion of Russian gas imports to avert supply cuts in Spain

Executive summary: Naturgy is negotiating to replace about €2 billion worth of contracted Russian gas with alternative international suppliers after the EU banned Russian gas imports, aiming to avoid supply disruptions in Spain. The outcome affects Spain's energy security, could influence gas prices and utility finances, and tests the EU's ability to enforce sanctions while maintaining supply.

Who is involved: Naturgy, EU authorities, international gas suppliers (unspecified), Spanish government.

Likely next: Naturgy expects to finalize swap agreements within weeks, potentially securing LNG or pipeline gas from Norway, Algeria, or the US; if unsuccessful, Spain may face curtailments or price spikes.

Naturgy is racing to renegotiate roughly €2 billion of contracted Russian gas after the EU’s ban on such imports, seeking alternative suppliers to keep Spanish homes and industry supplied. The move highlights the tension between sanctions compliance and energy security, as any shortfall could trigger price spikes or rationing. Analysts note that success will depend on the speed of LNG and pipeline deals from Norway, Algeria or the United States, while failure could expose the utility to regulatory penalties and higher costs.
