Louth County Council Approves 100m Meteorological Mast
PLANNING: 100m Meteorological Mast Approved for Drumshallon

Green Light for 100-Metre Lattice Mast in County Louth

Louth County Council has officially granted planning permission for the erection of a temporary 100-metre high lattice-type meteorological mast at Drumshallon.

The application, submitted by EDF Renewables Ireland in March, sought permission for the substantial structure to facilitate the measurement of local climate conditions. The mast will be secured to ground anchors using guy wires and will be equipped with various meteorological instruments.

Technical Specifications and Safety

To ensure safety and environmental protection, the proposed development includes several specific features. Near the top of the lattice section, an Infra-Red LED aviation light will be fitted to alert aircraft.

Furthermore, in an effort to protect local wildlife, the council has mandated the following:

  • Bird Deterrents: Flight deterrent markers must be fitted to each guy wire at approximately 10-metre intervals.
  • Structural Security: The mast will be fixed via a comprehensive system of ground anchors and wires.
  • Climate Monitoring: Integration of specialized sensors for high-altitude weather data collection.
The development is part of a broader data-collection phase regarding local renewable energy potential in the Mid Louth region.

Strict Planning Conditions

While the initial application requested a five-year duration for the mast, Louth County Council granted permission on 10 April subject to nine specific conditions. Most notably, the local authority has shortened the permitted timeframe for the structure.

The council stated that the temporary mast and all associated ancillary development must be removed no later than three years from the date of the commencement of development.

Impact on Drumshallon

The site at Drumshallon was selected due to its strategic position for monitoring wind speeds and atmospheric pressure. Once the three-year term concludes, the developer is required to reinstate the land to its original condition.

The grant of permission marks a significant step for EDF Renewables as they assess the suitability of the Louth landscape for future projects.
