Planning permission has been granted for the East Cork landfall segment of the €1bn Celtic Interconnector power link between Ireland and France, according to RTÉ News.

The 500km subsea cable, a joint project of EirGrid and France’s Réseau de Transport d’Electricité, will be the first direct energy link between the two countries, as previously reported on Afloat.ie.

Following a public consultation three years ago, a site at Youghal was chosen for the landfall section at the Irish end.

Approval by An Bord Pleanála covers the cable plus associated infrastructure such as that for power conversion and connection to the national grid.

Pending the granting of a foreshore licence for offshore developments, as well as a marine licence from UK authorities for the cable route, it’s expected the Celtic Interconnector could be activated by 2026.

RTÉ News has more on the story HERE.

The State’s electricity transmission grid operator EirGrid has opened a two-month consultation on proposed south coast landfall and converter station locations for its electricity link between France and Ireland writes Lorna Siggins.

The Celtic Interconnector will be the first direct energy link between Ireland and France, running some 500 km under the sea from east Cork to the French north-west coast. A further 40 km of underground cable will be laid on land.

The project is being jointly developed by EirGrid and Réseau de Transport d'Électricité, the French electricity transmission system operator, with a target completion date of 2026.

Eirgrid is seeking the public’s reaction to a shortlist of three proposed landfall locations, and a shortlist of six proposed location zones for a converter station in east Cork.

The convertor station converts direct current electricity to alternating current and vice versa.

It has scheduled a series of public information days in east Cork between April 23rd and May 3rd (see list below).

The state-owned company says that the link will “put downward pressure” on the cost of electricity, while improving security of supply, providing a direct fibre optic telecommunications link, and facilitating further development of renewable sources.

A previous consultation round had confirmed east Cork as the most suitable location in Ireland for the project, which will have a capacity of 700 megawatts (MW).

Eirgrid says this capacity is enough to power 450,000 households, and the cable will allow both the import and export of electricity.

Eirgrid says that the proposed shortlisted landfall locations - Ballinwilling strand, Redbarn beach, and Claycastle beach – between Ballycotton and Youghal in east Cork were selected from a list of five.

The proposed shortlisted sites for the converter station are in Ballyadam, Leamlara, Knockraha, Pigeon Hill, Kilquane and Ballyvatta - all inland and north of Cobh - and these locations were selected from a list of 14 options, it says.

Eirgrid says that each location was assessed against five criteria; economic, technical, environmental, socioeconomic and deliverability.

EirGrid is encouraging communities and stakeholders to “share their feedback” on the proposed shortlists.

“The shortlists are provisional. Feedback from communities, local representatives, and other stakeholders will be critical to ensuring that we can assess each option fully and make informed decisions when confirming the shortlists,” Eirgrid spokeswoman Louise Glennon states.

Stakeholders, communities and members of the public are invited to respond by Monday, June 10th, by online, by email, by phone, in writing or by attending one of a number of information days in east Cork, as below:

Lisgoold Community Centre - Tuesday 23 April - 2pm – 8pm

Knockraha Community Centre - Wednesday 24 April - 2pm – 8 pm

Carrigtwohill Community Centre - Tuesday 30 April - 6pm – 9pm

Midleton Park Hotel - Wednesday 1 May - 2pm – 8pm

Cloyne Parochial Hall - Thursday 2 May - 6pm – 9pm

Walter Raleigh Hotel, Youghal - Friday 3 May - 2pm – 8pm

#MarineNotice - The survey vessel VOS Sweet (Callsign PCPE) is currently conducting offshore geotechnical and environmental survey operations associated with the proposed Celtic Interconnector on behalf of EirGrid.

The VOS Sweet was set to commence operations yesterday, Monday 18 June, and will operate on a 24-hour daily basis for approximately two weeks in two main corridors off East Cork to three landfall points: Ballinwilling Strand (Ballycotton Bay); Redbarn Beach and Claycastle Beach (Youghal Bay).

The survey is to collect geotechnical data utilising a Vibrocorer (VC) and Cone Penetration Test (CPT) spread and environmental (benthic) data utilising Grab Sampler spread. The survey will be conducted under Foreshore Licence FS006811. Common frequency VHF Channel 16 shall be used throughout the project.

Details of the route centreline co-ordinates as well as intended locations for the VC, CPT and benthic sampling are included in Marine Notice No 26 of 2018, a PDF of which is available to read or download HERE.

Meanwhile, Providence Resources is carrying out a site survey on its FEL 6/14 licence, called Newgrange, situated between the Southern Porcupine and Goban Spur Basins some 260km off the South West Coast.

The eight-day geophysical survey by the MV Kommandor (Callsign MCJO2), was scheduled to commence on Monday, is using dual-frequency side scan sonar, single-beam and multi‐beam echosounders, side scan sonar, sub‐bottom profilers and magnetometer.

Seabed (benthic) samples will also be taken using a box corer or grab as appropriate, and geotechnical sampling will be undertaken with a piston corer to a minimum target depth of 6m below the seabed.

In addition to the above, and to accurately determine potential future drilling hazards over the Newgrange location, the proposed survey will also include a high resolution 2D seismic which is not expected to exceed two days.

Survey operations will be conducted on a 24-hour basis. The MV Kommandor will be displaying shapes and lights prescribed in the International Rules for the Prevention of Collisions at Sea (COLREGS) Rule 27, to indicate that the survey vessel is restricted in its ability to manoeuvre. A listening watch will be maintained on VHF Channel 16, and the vessel will actively transmit an AIS signal.

Co-ordinates and a map of the expected working area are outlined in Marine Notice No 25 of 2018, a PDF of which is available to read or download HERE.

#MarineNotice - The Sandpiper jack-up platform is conducting nearshore geotechnical survey operations associated with the proposed Celtic Interconnector on behalf of EirGrid south of East Cork.
