Oran O'Flaherty

Oran has a passion for a sustainable energy future with new exciting innovations but also a keen appreciation for the importance of efficiently utilising current infrastructure.

Oran's technical understanding and ability to effectively communicate all aspects of a project makes him an adaptable and resilient project manager. Oran holds a Master of Mechanical Engineering degree, capping his education off with a highly regarded thesis on the feasibility of transitioning the Irish natural gas grid to hydrogen.


He has gained valuable experience working firstly on the Irish Gas Grid and then for the Electrical Transmission system operator.


This has provided him with a broad understanding of all aspects of energy systems, and adapting projects to take advantage of current infrastructure.


Oran quickly understood the importance of not just the need for a strong technical engineering background, but also the importance of effective communication within the project team and publicly. He has worked in Ireland, Canada and New Zealand and complimented his studies with time in Singapore. He utilises this experience of different work environments to get the best from all members of a project team.


Oran's strengths lies in managing and communicating with all stakeholders of a project. He takes responsibility and ensures that the project team are given everything needed to successfully deliver initiatives on time, on budget and of exceptional quality.
