Gas and electricity operators to collaborate on future energy scenario planning

Northern Ireland’s electricity and gas transmission system operators have signed an agreement to deepen collaboration and the alignment of investments in both the electricity and gas systems.

A memorandum of understanding has been agreed between SONI, the electricity transmission system operator for Northern Ireland and Gas Market Operator Northern Ireland (GMO NI) on behalf of gas transmission system operators Mutual Energy and GNI(UK). This agreement will facilitate closer collaboration, expert and transparent knowledge sharing, more regular engagement, and intelligence gathering to support holistic energy planning, helping safeguard security of supply and decarbonisation opportunities. 

Mark Raphael, General Manager, GMO NI said: “The development of robust potential pathways for the future energy system has never been more important in this changing energy environment. As we transition towards net zero, we expect the role of gas transmission to evolve while continuing to play a pivotal role supporting power generation when there is a lack of renewable energy generation such as wind. 

“Demands on the gas and electricity grids are becoming increasingly integrated and it is essential that planning and policy in Northern Ireland are informed by a joined-up view of the future energy landscape. This memorandum of understanding between the gas and electricity transmission system operators in Northern Ireland represents a key step in that direction.” 

Gerard Carlin, Director of Networks and Innovation at SONI said: “We are pleased to announce this memorandum of understanding with the Gas Market Operator for Northern Ireland. This agreement is a major milestone in Northern Ireland’s energy transition as it will allow us to deepen industry ties and plan our energy future in an aligned whole system and plan-led manner. 

“We have always had a strong relationship with Mutual Energy and GNI (UK), and this partnership will enable us to better collaborate and ensure the alignment of investments in both the electricity and gas systems. That will be beneficial for the industry, and most importantly for consumers, as we seek to deliver a cleaner, more secure, and affordable energy system.”
