The disposal process forms part of the commitments adopted by Eni to settle antitrust proceedings commenced against the company by the European Commission.

At the time the agreement was struck the European Commission said “This will ensure that third-party requests to access the gas pipelines will be dealt with by an entity independent of Eni, the main supplier of gas in Italy.”

The TENP pipeline system consists of two pipelines both 36–38 inches in diameter running 500 km across Germany from Bocholtz, at the Dutch border, where the TENP pipeline system is connected to the Dutch network, to the Swiss border, close to Wallbach, where the TENP pipeline system is interconnected with the Transitgas pipeline system.

The Transitgas pipeline is 293 km long and transports natural gas mostly from the Netherlands and from Norway. It crosses Switzerland for 165 km from Wallbach to Passo Gries at the Italian border where it joins the Italian network.
