To assist ESB networks, GMC has encouraged the development of a number of teams whose skills in this field have been honed over the past two decades.
     
  Whilst GMC has always striven to maintain a multidisciplinary workforce, nevertheless, it became clear in the early days that some specialist units would need to be trained up. This is particularly evident in the electricity sector of the Group. To assist ESB Networks, GMC has encouraged the development of a number of teams whose skills in this field have been honed over the past two decades.

With careful management, skilled teams have been nurtured and developed so that now GMC can offer high grade Civil Engineering solutions in some of the largest Power Stations. Our management and teams have worked in generating stations such as Poolbeg and Shellybanks. ESB bulk supply situations such as Carrickmines 220kV transmission station. For the past decade GMC were the sole ESB contractor for 220kV cable installations.

Running projects in such hi-tech environments has meant that GMC has had to call on all the skills and experience at its disposal in order to deliver the level of completion demanded by ESB. This experience has paid off with GMC developing its own Bentoniting System using specially designed clamps. As well as this, the Group has designed its own shuttering system making the construction of chambers and joint bays in the electricity environment structurally sounder and quicker to erect.

Recently GMC's Power Division has been involved in bringing power to the Waste-to-Energy facility for Indaver Ireland at Duleek, Co. Meath.

Among the more high profile projects the division has played a central role in, is The East-West Interconnector, a high-voltage direct current submarine and subsoil power cable project, for connecting the UK and Irish electricity markets. The project is being developed by national grid operator EirGrid. The East-West Interconnector will have a total length of 261 km, of which 186 km is submarine cable and 75 km is subsoil cable. The link will connect converter stations at Rush North Beach, County Dublin, Ireland, and Barkby Beach in North Wales. The interconnection will use ±200kV HVDC Light cables with a capacity of 500 MW. It is the first HVDC Light transmission system project, which uses ±200 kV cables. The cables and converter stations are provided by ABB.
