What happened
Türkiye’s Energy Market Regulatory Authority has amended the investment-limit schedule underpinning Aksa Gemlik Natural Gas Distribution’s retail sales tariff for the 2022–2026 period. The update places the company’s 2026 investment ceiling at TL9,473,933.
That figure compares with a TL4,376,502 ceiling for 2025 in the revised schedule. The regulator also introduced an additional investment-ceiling line of TL5,486,764 for 2026. Energy and tariff planning teams using this framework should incorporate both 2026 values when assessing the company’s permitted investment envelope.
According to Enerji Günlüğü, the Energy Market Regulatory Board adopted Decision No. 14880 on 17 September 2026. The measure became effective when it appeared in Official Gazette issue 33375 on 19 September 2026.
Why it matters
The new 2026 main ceiling is approximately 2.2 times the 2025 amount, equivalent to a 116% increase. It changes the investment capacity available under the tariff framework in the final year of the relevant five-year period.
The supplementary amount is distinct from the main annual ceiling. It is listed solely for 2026, while the schedule shows no corresponding additional-investment entry for 2022, 2023, 2024 or 2025. This distinction matters for comparisons across the regulatory period and for separating the standard limit from the 2026-specific allowance.
Revised investment schedule
The amended table records main investment ceilings of TL9,919,009 for 2022, TL8,891,168 for 2023, TL7,566,711 for 2024, TL4,376,502 for 2025 and TL9,473,933 for 2026. Only the final year carries the additional TL5,486,764 category.
The sequence shows that the 2026 adjustment follows lower limits in the preceding two years, particularly the TL4,376,502 amount assigned to 2025. The evidence does not specify the projects or expenditure types to be funded within either 2026 category.
Regulatory context
Aksa Gemlik operates under distribution licence DAG/366-28/066. The new decision replaces the relevant table in a prior board decision, No. 11342, dated 27 October 2022. The revision concerns the investment ceilings associated with the company’s retail sales tariff rather than announcing a new distribution licence.
What to watch
The revised limits have applied since 19 September 2026. Stakeholders reviewing tariff assumptions, capital plans or regulatory submissions for the period should distinguish the main 2026 ceiling from the separate supplementary amount.
