Gas Networks Ireland has appointed Diarmuid Collins as Director of Customer and Business Development, strengthening its senior team as the organisation expands its role in delivering a cleaner, more secure and sustainable energy system for Ireland.

Collins brings more than 15 years' experience at Gas Networks Ireland, having held senior posts across Treasury, Investor Relations and Commercial Finance. He also served as Acting Chief Financial Officer for 13 months while the recruitment process for a permanent CEO was underway.

In his new position, Collins will lead customer and business development activities, supporting the company's ambition to transition from natural gas to renewable gases, including biomethane and green hydrogen. These solutions have the potential to significantly cut Ireland's carbon emissions, complement intermittent renewable electricity generation and bolster energy security. He will also assume executive responsibility for Aurora Telecom, a division of Gas Networks Ireland.

Welcoming the appointment, David Kelly, CEO of Gas Networks Ireland, said: "Diarmuid has made a significant contribution to Gas Networks Ireland over the past 15 years and has consistently demonstrated strong commercial acumen, leadership and a deep understanding of our business. His experience across finance, strategy and the wider energy sector, together with his commitment to delivering value for our customers and stakeholders, make him exceptionally well placed to lead this important function. I look forward to working closely with him as we continue to deliver on our vision for a net-zero energy future."

Commenting on his appointment, Diarmuid Collins said: "I am excited to take on the role of Director of Customer and Business Development at such an important time for Gas Networks Ireland and the wider energy sector. Ireland's transition to a low-carbon economy presents significant opportunities, particularly in the scale-up of renewable gases such as biomethane and hydrogen. I look forward to working with colleagues, customers and stakeholders to accelerate this progress and help deliver a more sustainable, resilient and secure energy system for Ireland."

Originally from Nohoval in Co Cork, Collins is a Business graduate of the University of Limerick and holds a Master's degree in Economics and Finance from the National University of Ireland, Maynooth. He is also a Fellow of the Association of Chartered Certified Accountants (FCCA).
