The liberalisation of the Irish electricity market and the Single Electricity Market have introduced fundamental market reform, additional wide-ranging regulation and heavily revised industry codes and licensing.  We have been to the fore in advising existing and prospective market participants on Ireland’s evolving energy sector.  We provide specialist advice in all areas of regulation and compliance including policy developments and legislative reforms emerging at EU level, from the Department of Communications, Energy and Natural Resources (DCENR) and from the Commission for Energy Regulation (CER).

We specialise in advising on the acquisition, procurement, development, financing, construction and operation of generation plant, and have acted on projects to deliver and operate distillate fired OCGT plant, gas fired CCGT plant and large scale CHP plants, wind farms and waste-to-energy installations.  

We have advised on various aspects of the grid code and the new electricity market, including unit registration, licensing, compliant bidding, physical and financial power purchase agreements; connecting to the transmission and distribution system, including on contestability; priority dispatch; and end user supply contracts.
