County Derry wind farm enters operation, delivering 47 MW

ERG has announced that it has completed construction and started energising the Corlacky wind farm in County Derry, consisting of 11 Vestas V117 turbines at 4.3 MW each, for a total installed capacity of 47.3 MW.

The 11-turbine Corlacky Hill Wind Farm is located approximately 3km west of the village of Swatragh. 


The plant is expected to generate around 176 GWh annually, equivalent to approximately 3,750 full-load hours.


This output corresponds to 66,000 tonnes of CO2 emissions avoided and will meet the energy needs of around 55,360 households in the United Kingdom.


The renewable energy and REGOs (Renewable Energy Guarantees of Origin) produced by the Corlacky wind farm, were secured through a Power Purchase Agreement (PPA) (see press release on February 4 2025).


Paolo Merli, CEO of ERG, commented: 'The start-up of the Corlacky wind farm, located in an area with strong wind resources, confirms the strength of the Group’s growth strategy and reinforces our position in the United Kingdom, where we have 340 MW of installed wind capacity’.
