Bulgargaz freezes Botas fees for 15 months

Bulgaria's state gas supplier Bulgargaz and Turkey's Botas have frozen their gas-infrastructure contract for 15 months. During that period, Bulgargaz will pay only for the pipeline capacity it actually uses, rather than carrying fixed fees for reserved access whether or not gas flows through it (fakti.bg). For a state company that was paying large daily fees for Turkish LNG access regardless of deliveries, this is real money back on the table.

How crisis insurance became a bill

The deal dates to early 2023, when European governments were scrambling for alternatives to Russian pipeline gas. Bulgaria secured access through Turkish infrastructure, including LNG-linked import routes, as a backup. If another supply route failed, Sofia had a lane ready.

The problem is how capacity contracts work. "Capacity" is not the gas itself. It is the right to use space in a pipeline or entry point. A capacity fee works like renting a parking space: you pay whether your car is there or not. When gas was scarce and prices volatile, paying for that reserved space made sense.

The market has since shifted. EU gas consumption has fallen by roughly 17% from pre-crisis levels (Blockonomi). In July 2026, the European Commission said it saw no immediate concerns about gas supply security for next winter (European Commission). ACER, the EU's energy regulatory agency, confirmed that wholesale markets had stabilised further after the 2022–2024 crisis (2EU Brussels).

Lower demand and calmer supply mean Bulgargaz barely uses the Turkish route. Paying fixed fees for it stopped looking like insurance and started looking like waste. Days before the freeze, Bulgaria's energy minister confirmed negotiations were still in a "working phase" with no finalised terms (blitz.bg). The protocol is an interim fix, not a clean exit.

Who gains, and who still waits

Bulgargaz benefits first. Lower fixed costs improve its cash flow. Botas keeps the deal alive rather than facing escalation or non-payment.

Bulgarian consumers, however, should not expect cheaper gas bills. The July regulated price was EUR 37.70/MWh excluding access and transmission fees, a 5.84% month-on-month increase, though still below some European benchmarks (serbia-energy.eu). Whether the Botas savings eventually lower household tariffs depends on how Bulgaria's regulator treats the relief, and on how much Bulgargaz needs the money elsewhere.

That "elsewhere" is large. Sofia's district heating company Toplofikatsiya holds debts of about EUR 1.2 billion, a burden tied directly to Bulgargaz's own balance sheet (fakti.bg). Savings from the Botas freeze could easily be absorbed by losses in the system rather than passed through to household prices.

Why neighbours are watching

The freeze matters beyond Bulgaria because south-east Europe is in the middle of a route-building contest. Greece operates the IGB interconnector to Bulgaria, with 3 bcm annual capacity expandable to 5 bcm, and runs two LNG terminals (ICGB). Romania expects first gas from its Neptun Deep Black Sea field in 2027, with plateau output of about 8 bcm per year (OMV Petrom).

If cheaper Turkish access looks attractive long-term, it weakens the commercial case for Greek-linked routes. Greek coverage raised exactly this worry (gr.euronews.com). But the research found no evidence that the freeze has displaced volumes from Greek infrastructure so far.

Bulgaria does not need to abandon the Turkish route. It needs that route priced like an option it can choose to exercise, not a bill it must pay regardless. For 15 months, it has that. Whether the freeze becomes permanent depends on a renegotiation whose terms remain undisclosed. For now, Bulgaria has won relief from an expensive insurance policy, not liberation from the deal. Consumers may never see the savings if domestic energy debts swallow them first.
