Harnessing ‘vast’ renewables potential key as Scottish-Irish study looks at offshore grid

  A detailed study into how an offshore electricity grid between Scotland, Northern Ireland and the Irish Republic could be introduced has now been commissioned after being awarded European funding.
 
The second part of the flagship Irish-Scottish Links on Energy Study (ISLES) has now been given £1 million to examine how an offshore grid could be established by breaking down the complex financial, legal and regulatory issues that can affect cross-border energy projects.

Ministers from the three administrations, attending the British Irish Council summit in Derry-Londonderry in Northern Ireland, welcomed the development and committed to work together to examine how such a project could be brought to fruition.

The ISLES announcement comes days after SSE confirmed it would respond to a joint Scottish and UK government study into the potential for renewable energy on Scotland’s islands by submitting a needs case to Ofgem for a £780 million subsea cable link to connect the Western Isles to the national grid.

Speaking before the BIC meeting, First Minister Alex Salmond said the new ISLES European project funding, coupled with SSE’s progress on the Western Isles connectivity cable, offered “hugely encouraging progress” on the infrastructure necessary to allow the renewable energy industry in all three markets to reach its full potential.

The First Minister said:

“The waters around these islands have some of the most abundant offshore energy resources anywhere in the world, but in order to harness this vast potential it is vital that we have the infrastructure in place to transfer the energy that is generated to where it is needed.

“That is why the ISLES project is so important.  This innovative, cross-border study is examining how we can establish an offshore electricity grid to make this transference of energy easier, supporting our flourishing renewables industry by powering the nation and allowing the surplus energy it generates to be exported to other markets.”

Mr Salmond referred to the first part of ISLES which has already shown that an offshore grid was both technically feasible and economically viable.  The First Minister praised the British Irish Council as an example of how forums could allow administrations to “tackle issues of mutual interest in a positive, collaborative fashion.”

He added: “The timing of the ISLES funding is even more apt, coming as it does just days after SSE confirmed that the potential for renewable energy output on Scotland’s islands had led it to submit a needs case to Ofgem for its £780 million subsea cable link to the Western Isles.

“Taken together, these announcements offer hugely encouraging progress on the infrastructure that we need to secure to ensure the burgeoning renewables industry – in markets across these islands – is allowed to reach its full potential.”

Northern Ireland Energy Minister Arlene Foster welcomed the opportunity to work with the administrations of Scotland and the Republic of Ireland, adding:

“This project has the potential to send important investment signals to private sector companies who are considering investing in offshore grids as it will allow them to position their projects favourably when bidding for funding from Europe.”

Speaking from Ireland, Irish Minister for Communications, Energy and Natural Resources Pat Rabbitte said:

“I support the establishment of the Energy Study ISLES II. There is huge potential for capturing wind, wave and tidal energy and this cross-jurisdictional offshore integrated network is economically viable and competitive compared with developer-led stand-alone connected projects. It can potentially deliver a range of wider economic, environmental and market related benefits to both Ireland and the UK”.

The Irish-Scottish Links on Energy Study (ISLES) is a joint initiative between Scotland, Northern Ireland and Ireland examining how an offshore interconnectivity grid could be established to help aid the transfer of energy between the three markets.

The first part of the study – published in November 2011 – showed there were no technical barriers to the development of an ISLES offshore interconnected network, concluding that there were no environmental constraints and sufficient onshore network capacity in the UK for ISLES to be in place by 2020.
