The Trans Adriatic Pipeline (TAP) has made its Nea Mesimvria connection with Greece physically bidirectional, changing how gas can move between TAP and the Greek system. From Oct. 1, the point can operate as both an entry and an exit between TAP and DESFA. The update also affects how LNG-linked supply can access the trans-Adriatic network when capacity and market conditions allow.
Nea Mesimvria is now able to function as both an entry and an exit point between TAP and Greek transmission operator DESFA from Oct. 1. Previously, the connection operated primarily as a delivery point from TAP into Greece. The physical change increases flexibility between TAP and the Greek gas system.
The bidirectional operation means gas already within the Greek network, including supply originating from LNG terminals, can potentially flow into TAP when market conditions and capacity permit. This expands routing optionality across Greek LNG infrastructure, TAP, Albania and Italy. It also provides another potential route for LNG-linked supply into the trans-Adriatic network.
Implications for regional gas flows and trading
The development is described as commercially important as Greece strengthens its role as a regional gas hub. 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 bidirectional operation, those pipeline and LNG-linked systems can interact more flexibly.
The change strengthens competition between pipeline gas and LNG. Physical flexibility will not necessarily lower prices, but it gives traders more routing options and makes Greece 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 increasingly valuable.
