Gazprom Halts Armenia Gas Flows for Maintenance
Gazprom suspends pipeline deliveries to Armenia until late September, forcing the country to rely on domestic and Iranian reserves during the outage.
Gazprom has suspended natural gas deliveries to Armenia, citing planned maintenance on the North Caucasus-Transcaucasia Gas Pipeline. The shutdown begins Tuesday and is scheduled to continue until September 25, effectively halting the primary energy supply line from southern Russia through Georgia.
According to Gazprom Armenia, customers will draw from domestic reserves and additional imports from Iran during the interruption. This follows a similar maintenance window last September, highlighting the periodic dependency of Armenia’s energy grid on Russian infrastructure despite ongoing diplomatic tensions.
Supply Shifts to Iranian Imports
Russia supplied 2.7 billion cubic meters of gas to Armenia in 2025, representing 82% of the nation’s total imports. Under a bilateral agreement expiring at the end of the year, Moscow charges Yerevan a discounted rate of $177.5 per 1,000 cubic meters. The temporary loss of this volume necessitates an immediate logistical pivot toward alternative sources.
Gazprom Armenia confirmed that Iranian supplies will bridge the gap, a move that underscores Yerevan’s strategy to diversify its energy portfolio. Prime Minister Nikol Pashinyan stated on Friday that Armenia intends to move toward broader energy source diversification, reducing reliance on a single geopolitical supplier.
Geopolitical Tensions Drive Policy Shifts
The pipeline halt occurs amid deteriorating relations between Moscow and Yerevan. Although formally allied, Armenia has increasingly pursued ties with the European Union, a move viewed with suspicion by the Kremlin. President Vladimir Putin has demanded a national referendum on whether Armenia should deepen European integration or remain in the Eurasian Economic Union.
Pashinyan indicated last month that Armenia could begin the formal EU application process in the near future, which would trigger a membership referendum. This diplomatic realignment coincides with the operational pause in gas flows, reinforcing the narrative of decoupling from Russian energy dependence.
Operational Context of the Outage
The North Caucasus-Transcaucasia Gas Pipeline is the critical conduit for Russian exports to the South Caucasus. The maintenance period, lasting until September 25, mirrors the timeline of the previous year’s repairs. For Gazprom, the suspension is a scheduled operational event, but for Armenia, it represents a significant short-term supply shock.
The Moscow Times reported that the suspension is part of routine infrastructure upkeep, yet it lands at a sensitive time for Yerevan’s energy security. The company’s regional subsidiary confirmed the halt on Monday, ensuring that domestic and Iranian reserves are mobilized to maintain stability for end-users during the repair window.
