Proposed Derrygreenagh Wind Farm

The proposed Derrygreenagh Wind Farm will be located across three bogs:  Derryhinch, Drumman and Derryarkin which compromises of circa 2,100 hectares. Approximately 4% of this area will be used for turbine bases, crane hard-standings and access tracks, so much of the land area will not be required by the development.

Number of turbines: 25

The draft layout comprises 25 wind turbines. Apart from the turbines themselves. The other principal components of the wind farm are the foundations to support the turbine towers, access, crane hard standings, underground cables between the turbines, an electricity substation, and an electrical connection to the National Grid (Transmission Network) in line with system operator requirements.

Height of turbines: 200m

The proposed turbines will have an overall blade tip height of 200m. The exact make and model of the turbine will be dictated by a competitive tender process post planning and it will not exceed the maximum height of 200 metres.

Setback Distance: 800m

The turbine layout has been designed with a minimum setback distance of 800m to the nearest home from a turbine. This compiles with the Draft Wind Energy Development Guidelines (2019) which proposes a setback distance of four times the tip height. See accompanying A2 map for proximity of turbines to homes within 2km of a proposed turbine.

Wind Farm Output Up to 180 MW

Studies of the site have indicated that it may be capable of accommodating approximately 180 MW of Wind Energy. When operational, the proposed wind farm may generate over 550,000MWh*of renewable energy per annum.

Battery Energy Storage System

As part of this development, it is intended to install in the region of 50-100 MW of Long Duration Energy Storage. This system can store and discharge electricity for extended periods—typically 4 hours or more. Battery Storage Systems are designed to store excess energy and aim to provide reliable, dispatchable power over prolonged periods, especially during times when intermittent renewables like wind or solar are unavailable.
