The expert review into the North South Interconnector is expected to get underway shortly.
It's over five months since the Taoiseach told local Senator Robbie Gallagher that the contentious powerline would be looked at again.
Local communities and elected representatives in Monaghan and Cavan have continuously voiced their opposition to the overgrounding of the 400kV line.
The announcement of a further review in March was welcomed, however anti-pylon groups warned that it may be nothing more than a whitewash.
The North-South Interconnector has been assessed on a number of occasions, with all results showing that overhead pylons were "the most appropriate option".
A spokesperson for the Department of the Environment, Climate and Communications said that "notwithstanding" previous findings, Minister Eamon Ryan commissioned this short review to see of overgrounding remains valid.
Terms of Reference for the study were published on April 21st and on May 7th, the Department began a procurement process to appoint an independent expert to undertake the review.
The Department spokesperson confirmed to Shannonside Northern Sound that the process has now concluded and the international grid experts "will be appointed shortly"
It's expected that once started, the review will take eight weeks.
