The Trans Adriatic Pipeline (TAP) has made its Nea Mesimvria connection with Greece physically bidirectional, expanding flexibility between TAP and the Greek gas system. From Oct. 1, the Nea Mesimvria point can operate as both an entry and an exit between TAP and Greek transmission operator DESFA. Previously, the connection functioned primarily as a delivery point from TAP into Greece.
The bidirectional change allows gas already inside the Greek network, including supply originating from LNG terminals, to potentially flow into TAP when market conditions and capacity permit. This increases routing optionality across Greek LNG infrastructure, TAP, Albania and Italy. The update also supports Greece’s role as a regional gas hub.
LNG-linked flows and interaction with regional pipeline supply
LNG imports through Greece are increasingly moving north into Bulgaria and other Balkan markets, while TAP remains a major corridor for Azerbaijani gas towards Europe. With physical bidirectional operation, those systems can interact more flexibly. The change also strengthens competition between pipeline gas and LNG.
Physical flexibility does not necessarily translate into lower prices, but it provides traders with additional routing options. It also positions Greece as a more active balancing point between regional supply sources. As Southeast Europe shifts from single-route dependence toward portfolio trading, infrastructure capable of reversing flows becomes more valuable.
