TurkStream, Russia's last pipe to Europe, halts for June maintenance
An eight-day shutdown of the only remaining transit route foreshadows the EU's full Russian-gas phase-out by 2028
Summary
TurkStream, the only Russian gas pipeline still reaching the EU after Ukraine let its transit deal lapse on 1 January 2025, halted for scheduled maintenance from 2 to 10 June 2026, with work at the Russkaya pumping station and the Turkish receiving terminals zeroing deliveries to Hungary, Serbia and Slovakia. The outage is a preview: the EU Council has agreed to phase out all Russian gas imports by 1 January 2028, with short contracts allowed to run only to mid-June 2026 and long-term TurkStream deals to the 2028 cutoff. Each maintenance stop now lands on thin European storage, and the route's days are numbered as the bloc pivots to LNG and Norwegian pipe.
By the numbers
- 2-10 June 2026, TurkStream maintenance window (flows to ~zero).
- 1, Russian pipeline routes left to the EU (TurkStream).
- 1 Jan 2025, expiry of the Ukraine transit deal.
- 17 June 2026 / 1 Jan 2028, short- vs long-contract Russian-gas off-ramps.
- 3, main EU recipients via TurkStream (Hungary, Serbia, Slovakia).
Why it matters
TurkStream is the last physical thread of the once-dominant Russia-Europe gas trade. Its phase-out hardwires Europe's dependence on LNG and pipeline alternatives, raises the floor under TTF, and strands landlocked buyers who resisted the ban, a structural shift the June outage rehearsed.
What to watch
- Hungarian and Slovak resistance to the 2028 cutoff in EU sanctions talks.
- Whether maintenance stops lengthen or recur as the route winds down.
- Replacement flows: incremental LNG and Norwegian/Azeri pipe.
