Nearly 18 months ago EirGrid applied to build a high-capacity electricity interconnector between Dublin and Tyrone, the second between the Republic and Northern Ireland.
The proposed line stretches over approximately 135km, linking the existing transmission networks in both jurisdictions between an existing substation in Woodland, Co Meath, and one planned for Turleenan in Co Tyrone.
In the Republic the development, now approved by An Bord Pleanála, will pass through Monaghan, Cavan and Meath, requiring 299 steel lattice-style pylons, ranging from 26m to 51m in height, linked to an existing pylon line.
The line has been designated by the European Commission as one of 195 key energy infrastructure projects across the EU that have been dubbed as projects of common interest.
Such projects, the commission says, “are essential for completing the European internal energy market, and for reaching the EU’s energy policy objectives of affordable, secure and sustainable energy”.
The decision by An Bord Pleanála–- one that has come with conditions – followed a second oral hearing in a Carrickmacross hotel in Co Monaghan. It lasted 12 weeks, and was one of the longest such public inquiries in the State's history.
The plan for a second interconnector between the Republic and Northern Ireland goes back 14 years when an initial feasibility study was carried out on the possibility of building a 220KV line between Tyrone and Dublin.
However, as the peace process bedded down, plans became more ambitious, and a further North/South study was carried out in 2005, which this time investigated the potential and the need for a 275KV line.
A year later the cross-Border interconnector that had been shut down during the Troubles following a bomb attack on pylons near Crossmaglen, Co Armagh, was finally restored.
Information days
Meanwhile, approval was given for planning for a second line – one that had now grown to a 400KV plan – which saw EirGrid hold information open days in Meath, Cavan and Monaghan.
It launched an information telephone and email service in October 2007, though two years passed before it submitted a planning application to An Bord Pleanála under the Strategic Infrastructure Act.
Following a statutory consultation period, an oral hearing by An Bord Pleanála began in Carrickmacross in May 2010. However, it was brought to a sudden end within weeks, and Eirgrid withdrew the application.
The late Fine Gael councillor Owen Bannigan had revealed an error in EirGrid's plans in the stated height of the proposed electricity pylons that would run across Monaghan on the 21st day of the oral hearing.
Two years later, Eirgrid's then newly-appointed chief executive Fintan Slye told agendaNI magazine that a second North/South interconnector was "absolutely critical" for Northern Ireland's future security of supply.
In November 2014, EirGrid submitted its draft application file to Bord Pleanála for review. Four months later EirGrid republished its proposed line route, one that would form the basis of its planning application.
Alignment
The route plan followed a review of the December 2013 line design. The review resulted in some of the proposed tower locations being repositioned along the alignment, but the alignment itself was not changed.
By June 2015, EirGrid was ready to place a public planning notice in newspapers, followed by the submission of an application shortly afterwards to the Strategic Infrastructure Division of An Bord Pleanála.
Ten weeks of public consultation followed, one that prompted 900 replies. Last January, Eirgrid offered to meet people in their homes or at one of their information offices or elsewhere to discuss their concerns.
Throughout campaign groups in Monaghan and Meath have criticised the consultation, but most particularly EirGrid’s “insufficient attention” to alternatives.
Localised impacts
“In
England
they’re pulling down pylons; in Ireland we’re putting them up,” said one Meath resident.
The final ruling from Bord Pleanála runs to 615 pages. In its conclusions the planning authority declares that it recognised that the pylons’ plan would “result in a limited number of localised impacts”.
However, “having regard to the identified strategic need for the development”, the plan is in accordance with planning rules “subject to compliance with the mitigation measures” that the planning appeals board has laid down.
