Eoin Cassidy


Eoin is a partner in our Construction team and practises in both contentious and non-contentious construction law. He advises and represents state bodies, banks, developers, contractors, engineers, and other construction professionals on construction, energy, planning and environmental matters.  

Energy Law is a significant part of Eoin’s expertise.  He has acted for funders and developers in relation to the financing, acquisition and disposal of a significant number of wind farm projects in Ireland. He also provides on-going advice to wind farm developers on construction, planning, environmental and grid connection for projects at the pre-development and construction stage. In addition, Eoin has advised contractors on contractual issues in design, build and operate contracts for power plants.

On the contentious side, Eoin has acted for clients in a number of High Court and Commercial Court proceedings, conciliations and arbitrations representing the interests of employers, contractors and sub-contractors in the resolution of disputes in high-value matters.

Eoin is the president of the Energy and Environment Commission in AIJA and has been recognised by Who’s Who as an expert lawyer on environmental matters.
