IGT176: Changes to IGT UNC to enable UNC0887 ?Facilitating Bi-Directional Connections Between IGT Pipelines and the NTS?

Summary

IGT176 modifies the Independent Gas Transporter Uniform Network Code to align with UNC0887, which enables bi-directional gas flows between IGT pipelines and the National Transmission System. The modification has reached implementation stage following authority decision. This enables gas to flow in both directions at connection points between local IGT networks and the main transmission system.

Why it matters

This is a technical alignment change that supports gas system flexibility but does not affect electricity markets. The bi-directional capability could support future hydrogen or biomethane injection from local networks.
