Plans to refurbish Monvallet power station remain a possibility

Plans to refurbish Monvallet power station remain a possibility

Plans to refurbish the power station at Monvallet, just outside Louth Village, remain a possibility.

EirGrid Plc have lodged a planning application with Louth County Council in recent days to extend the duration of the permission they received for its upgrade in December 2014.

They are seeking permission to refurbish the existing Louth 275kV substation. This will comprise the replacement and/or reconfiguration of the existing circuit breakers, disconnects, instrument transformers and surge arrestors with equivalent new circuit breakers, disconnects, instrument transformers and surge arrestors.

There would also be modifications to the existing generator room comprising new opes on the northern and western elevations to facilitate the provision of a new internal diesel generator; the removal of the existing underground oil storage tank and provision of a new overground oil storage tank of less than 3,500 litre capacity within the footprint of the existing generator room; the relocation of the existing 110kV capacitor bank from the north east of the site compound to the north west of the site compound and the provision of two new 110kV wing couplers and the replacement of existing 110kV off-line couplers with two new 110kV in-line couplers.

EirGrid are also seeking to install 30 protection and control cabins approximately 3.75 metre in length and 3.15 metre wide x 3.5 metre in height located adjacent to the existing bays; the installation of 12 new 110kV and nine new 220kV surge arrestors.

There would also be the installation of 22 lightning rods, approximately 2.5 metre high, on top of the existing 110kV busbar gantries; the installation of one new lightning mast, approximatly 15 metres high.

They are also planning an extension of the site compound to the north by 2,671 square metres to enhance internal vehicular movement within the substation. This will include associated new perimeter fencing on the northern side of the substation. Permission has also been sought for the installation of a new electrified fence (approximatly 3.6 metres in height) inside the existing palisade fence (approximately 2.6 metres in height); and all associated site development works.

A decision on the matter is due by November 28th.
