GMO NI Background

Previously the gas transmission market in Northern Ireland had been operated by four separate Transmission System Operators (TSOs), PTL, BGTL, WTL and GNI (UK).

In the interests of streamlining the interaction between gas suppliers and TSOs, the Utility Regulator has sought to create a single system operator to manage all the commercial functions on behalf of the TSOs in Northern Ireland.

The TSOs have now put in place arrangements to establish GMO NI and ensure there is a single interface for dealing with all commercial aspects of operating the transmission networks.

The TSOs are still responsible for operating and maintaining their respective transmission networks.

Functions and Benefits of GMO NI

The main purpose of GMO NI is to simplify the processes for gas suppliers by providing a single point of contact for all commercial activities.

This is delivered through a new single IT gas transmission management system (DELPHI), a consolidated single code and a single team to manage all commercial processes and address any queries from suppliers.The GMO NI will manage a range of functions including:

Market Operations 

(capacity bookings, nominations, allocations)

Procurement and administration/operation of a single IT system

Invoicing function – Shippers will receive all invoices issued by GMO NI and not from TSO’s

ensuring transparency

Although the new arrangements under GMO NI should benefit all stakeholders in Northern Ireland’s gas transmission market, there are very clear benefits for gas shippers. These include:
