Mason Hayes & Curran


Mason Hayes & Curran is a full service Irish business law firm, with 80 partners and offices in Dublin, New York and London.  
Our firm is a market leader in advising on energy and infrastructure projects and transactions in Ireland.
Our team advises a wide range of clients in the energy sector, including utilities, investors, developers, financiers and regulators.  We have acted on the project finance, development or acquisition of electricity generation – both thermal and renewable – having cumulative generation capacity in excess of 1.5GW. This includes advising on the largest Irish energy transaction of recent years, the acquisition by Brookfield Renewable Energy Partners of the renewable energy assets of Bord Gáis Éireann.  
We have also advised on transactions involving electricity and natural gas network assets, and petroleum exploration and extraction. We advised the Commission for Energy Regulation and the Northern Ireland Authority for Utility Regulation on the development of the all-island Single Electricity Market (SEM).
With expertise in key areas of law such as energy regulation and markets, construction, planning and environmental, real estate, banking and corporate law, we are well positioned to provide clients with the most comprehensive suite of legal advice available to the Irish energy sector.
As a strong pipeline of private sector investment in Irish energy continues to deliver, we advise the majority of the leading banks advancing credit for the project financing of energy projects in Ireland.
