Beginning October 1, 2026, the Trans Adriatic Pipeline (TAP) will shift the Nea Mesimvria interconnection point in Greece to bidirectional functionality. This infrastructure upgrade will enhance gas system flexibility for European markets dependent on supply from the Shah Deniz field in Azerbaijan.
Why it matters
The transition to bidirectional flow improves market integration and operational agility within the regional gas network. By enabling the interconnection point to function as both an entry and exit, the change allows for more dynamic management of gas volumes across the 877-kilometer pipeline system.
The Trans Adriatic Pipeline currently supplies 15-16 percent of Italy's total gas imports, with more than 62 billion cubic meters of gas transported to date. This upgrade adds 1.2 billion cubic meters of long-term annual capacity to the network.
The players
Trans Adriatic Pipeline
An 877-kilometer pipeline infrastructure system transporting natural gas from Azerbaijan to European markets.
DESFA
The operator of the National Natural Gas System in Greece that manages the interconnection with the pipeline.
The details
The Nea Mesimvria interconnection point serves as a critical link connecting the TAP system to the National Natural Gas System operated by DESFA. By enabling bidirectional flow, the pipeline system allows gas to be routed through the point as either an entry or an exit based on demand. This technical shift aims to optimize transport efficiency and support broader emission intensity reductions under the 2026-2030 Carbon Management Plan.

Market Landscape
This development aligns with broader efforts to improve the resiliency and integration of European energy corridors. It follows the precedent established by the Third Energy Package which emphasizes increased interconnection flexibility across the continent.
Energy-intensive businesses and gas-reliant operators should monitor regional supply pricing as bidirectional flow enables new routing options. The additional 1.2 billion cubic meters of capacity may impact long-term procurement contracts in the Mediterranean and Balkan regions.
The takeaway
The move toward bidirectional pipeline operations signifies a shift toward more flexible, market-responsive energy transport infrastructure. Operators should review their gas supply agreements for potential shifts in availability as the pipeline optimizes for its increased capacity limit.
