• Length of the Polish section: approx. 680 km;
• Diameter of pipe: 1420 mm
• Maximum operating pressure: 8.4 MPa
• Compressor stations constructed: Włocławek, Kondratki, Ciechanów, Szamotuły and Zambrów;
• Total installed capacity of 5 compressor stations: 600 MW
• 33 valve stations equipped with cut-off valve systems enabling shut-down of parts of the pipeline between the stations and flow diversion through another line with a limited capacity loss;
• Total capacity of the first line: 32.3 billion cubic metres of gas per year
• Total capacity of both lines: 65.7 billion cubic metres of gas per year
• Planned supplies to Poland after completion of both lines: up to 14 billion cubic metres of gas per year

It is projected that the pipeline system will achieve its full installed capacity (65.7 billion cubic metres of gas per year) in 2010 (2 lines, 5 compressors).
