Mainline provides a diverse range of services from the design and build of electrical substations, to airfield installations, to turnkey wind and solar energy solutions. We operate across a wide range of sectors including energy, aviation, data-centre and manufacturing. Our success has been built on fostering relationships with key clients, and delivering value focused engineering solutions.

Internationally we deliver on large scale Windfarms.

In recent years we have expanded our international operations and completed significant projects (73 Turbine and 69 Turbine) on two of Europe’s largest wind farms.

We deliver airfield installations.

Several years ago we diversified into the aviation space, and won our first project with the Dublin Airport Authority (DAA). Through the delivery of a quality service, we have since successfully secured and delivered many projects in Dublin, Cork and Shannon Airports, as well the full electrical package on the new Dublin Airport North Runway, establishing us as the leading Irish provider of airfield electrical works.

We deliver electrical substations.

Services we offer include the complete design, build and commissioning of electrical substations from 10kV to 220kV, with clients in the renewable, industrial and educational sectors. We also work closely with the ESB on live HV/MV substation upgrades.

We deliver MV/HV cable installation.

We provide a full design, procurement, installation and commissioning service for cables of all voltages from 10kV to 220kV. We have also completed numerous “contestably” grid connections for windfarms, some of which have been up to 35km in length.
