Production at the Tengiz oil field in Kazakhstan is set to resume, according to the Ministry of Energy, which has been monitoring the situation since January 18. The restart does not, however, represent a full return to pre-shutdown production levels. While the disruption had no immediate impact on global oil prices, which continued to decline at the time of the outage, it triggered widespread electricity restrictions across western Kazakhstan.

On January 21, Brent crude futures fell by 79 cents (1.22%) to $64.13 per barrel, while West Texas Intermediate dropped by 64 cents (1.06%) to $59.72 per barrel, Reuters reported. By then, production at Tengiz had already been suspended for three days, with sources indicating that the downtime would continue for another seven to ten days.

From January 20, local authorities in Atyrau and Mangistau regions reported systemic electricity supply restrictions, including altered street-lighting schedules in Atyrau to conserve power, amid reduced gas deliveries to regional generators.

The Ministry of Energy did not publicly respond to this until January 22, when, in a statement, it confirmed that gas turbine units at Tengiz were shut down on January 18. At the direction of Minister Erlan Akkenzhenov, his deputy was dispatched to oversee the situation on the ground. A special commission was established to investigate the incident, including representatives from the State Energy Supervision and Control Committee, the Atyrau Region Akimat’s Energy Department, KEGOC JSC, and Tengizchevroil LLP.

No official explanation for the shutdown has yet been provided. However, some Kazakh energy experts have publicly speculated about a possible link to recent Ukrainian drone attacks on the infrastructure of the Caspian Pipeline Consortium (CPC), which plays a vital role in exporting Kazakh oil.

Oil and gas analyst Olzhas Baidildinov drew a connection between the attacks and cascading effects on domestic energy supply: “They hit the CPC; exports declined, followed by oil production. Gas production declined along with oil. Gas is essential for electricity generation in western Kazakhstan,” he said. Baidildinov added that imported gas and electricity from Russia helped prevent more severe outages, though the energy crunch underscores longstanding vulnerabilities in Kazakhstan’s infrastructure.

Baidildinov also referred to recent criticism from President Kassym-Jomart Tokayev, who at the 5th session of the National Kurultai voiced dissatisfaction with the energy sector, signaling potential personnel changes.

On January 26, the Ministry of Energy announced that production at Tengiz would restart “in the near future,” and, at 4 a.m., the second-generation plant resumed operations, initiating raw material flows from the Royal field.

“The current flow to the ZVP is 2,500 tons per day. Specialists are systematically increasing the supply of multiphase flow (oil and gas) to reach design capacity. At Tengiz, all technical and human resources have been mobilized to inspect energy facilities and power distribution systems,” the ministry stated.

Officials emphasized that restoration efforts are under constant oversight. “TCO remains committed to ensuring reliable production and will increase volumes in stages, as infrastructure readiness and safety have been confirmed.”

While the ministry has yet to publicly acknowledge the cause of the shutdown, officials have avoided linking it to attacks on the CPC. Analysts note that such issues can be politically sensitive, particularly in western Kazakhstan, which has been the epicenter of major protests in the past, and say authorities have so far framed the incident in technical rather than geopolitical terms.
