The firm said the move is a response to increased demand for legal expertise in energy delivery and complex project structuring, driven by planning reform, Ireland’s climate targets and the ambitions set out in the National Development Plan.

Valerie Lawlor, partner and head of the energy group at McCann FitzGerald, said: “Peter brings additional strength to our bench, particularly in matters relating to the regulatory framework for infrastructure delivery and energy transition.

“His technical insight and commercial acumen will be invaluable as clients navigate regulatory reform and the demands of Ireland’s energy transition. I’m delighted to welcome him to the team.”

Managing partner Stephen Holst added: “Peter’s appointment is part of our strategy to unite the best insights, deep sectoral expertise, and commercial fluency within a single, integrated team in this key sector. 

“This collaborative approach is about giving clients the clarity, confidence and strategic advice they need to deliver complex, future-focused projects.”

Commenting on his appointment, Mr McLay said: “Ireland is entering a critical phase in its energy and infrastructure journey, and clients need legal advice that is technically sound, commercially astute and sector-aware.

“McCann FitzGerald has built a team that understands the full complexity of ambitious projects and the urgency of delivery. The team here is doing outstanding work and I look forward to helping clients to unlock new opportunities ahead.”

Mr McLay’s appointment follows a series of senior hires and promotions at the firm, including the recent appointments of Ciara O’Leary as partner in the investment management group and Maedhbh Clancy as partner and head of knowledge.

In May, the firm announced nine new partners across its core practice areas.
