Coffey delivers civil and mechanical engineering services for major energy infrastructure projects in Ireland and the UK. Our work includes large-scale civil engineering for electricity generation, grid-stability infrastructure and renewable energy facilities.
We support utilities, energy operators and renewable developers through projects such as synchronous condenser installations, emergency generation facilities, bioenergy plants and offshore wind substation works. These projects contribute to grid stability, security of supply and the development of low-carbon and renewable energy systems.
Our Energy Experience
Coffey has a long history of involvement in energy-related engineering projects, including Ireland’s first commercial wind farm in 1991 and significant enabling works for modern renewable and conventional generation assets.
Our capability is demonstrated through the delivery of complex civil and mechanical works across a range of energy technologies, including synchronous condensers, open-cycle gas turbines, bioenergy facilities, hydrogen-ready systems and offshore wind infrastructure.
Key documented experience includes:
-
Delivery of Ireland’s first commercial wind farm
-
Civil works for a synchronous condenser supporting grid stability
-
Civil works for an open-cycle gas turbine project above 260 MW
-
Enabling works for a 300 MW biofuel/hydrogen-ready generation plant
-
Civil delivery for a 90,000-tonne-per-year bioenergy (AD) plant
-
Substation works for one of the world’s largest offshore wind developments in the UK
