Some modern data centres designed to support artificial intelligence (AI) <\/a>demand more electricity than is needed to power 100,000 homes, an Oireachtas committee has been told.<\/p>\n

Senior officials from EirGrid, ESB Networks, and the Commission for the Regulation of Utilities <\/a>were before the Oireachtas committee on artificial intelligence on Tuesday.<\/p>\n

The committee heard that the latest projections on future demand suggest data centres will account for a median level of about 35 per cent of all the electricity demand within the State by 2035.<\/p>\n

\u201cWhile conventional data centres often require between 10 and 25 megawatts of power, large AI-focused facilities can exceed 100 megawatts in demand with annual electricity consumption comparable to that of around 100,000 households,\u201d said Jim Gannon, the commissioner for the regulation of utilities.<\/p>\n

\u201cAs AI models continue to grow in complexity and scale, the electricity requirements of supporting their infrastructure are expected to increase correspondingly.\u201d<\/p>\n

At a press conference after an informal meeting of European energy ministers, Minister for the Environment Darragh O\u2019Brien was asked if he would block future data centres that used the equivalent electricity of 100,000 homes.<\/p>\n

He said Ireland is \u201cnot a large industrial nation\u201d and described the information, communication and technology sector as \u201cone of the cornerstones to our economy\u201d.<\/p>\n

\u201cMuch of that is underpinned by infrastructure including data centres,\u201d he said.<\/p>\n

\u201cI think a planned approach going forward, which is what we\u2019ve adopted now, is the is the way to do it, and that\u2019s good.\u201d<\/p>\n

Gannon told the Oireachtas committee many jurisdictions face similar difficulties in \u201cbalancing economic opportunity with energy security, network capacity and climate objectives\u201d.<\/p>\n

EirGrid, which manages the main electricity supply network, and ESB Networks, which manages local distribution and connections, have no powers to limit the number of data centres connecting to the grid except in \u201cconstrained areas\u201d where supply is an issue.<\/p>\n

The committee heard that Dublin, where almost 100 of the State\u2019s nearly 130 data centres are located, is defined as a constrained area.<\/p>\n

However, in response to a question from People Before Profit\u2013Solidarity TD Paul Murphy<\/a>, the committee heard the organisations still work with applicants to see if new connections are possible.<\/p>\n

Gannon said AI presents \u201csignificant opportunities for economic growth, innovation and productivity\u201d, but added a caveat that it also raises \u201cimportant questions\u201d about the infrastructure required to support it. <\/p>\n

\u201cData centres already represent a significant and growing component of Ireland\u2019s electricity system,\u201d he said. \u201cTheir share of national electricity consumption has increased from approximately 5 per cent in 2015 to around 23 per cent in 2025. Looking ahead, Ireland\u2019s most recent resource adequacy assessment projects that, under its median demand scenario, data centres and other new technology loads could account for approximately 35 per cent of Ireland\u2019s electricity requirement by 2035.\u201d<\/p>\n

The committee heard ways should be found to co-locate data centres close to sources of renewable energy, outside of Dublin where possible.<\/p>\n

This process has begun to be worked on in recent years but needs to be rolled out countrywide, said Gannon.<\/p>\n

Asked why domestic consumers pay far higher rates per unit for their electricity than the owners of data centres, he replied: \u201cWe are in a liberalised market, which is regulated, but it is liberalised in line with EU law. Larger users have the ability to engage in direct negotiations with suppliers, whereas that is not the case for domestic consumers who tend to operate in the market. And that is why we continue to encourage people to switch to keep competition alive.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"Some modern data centres designed to support artificial intelligence (AI) demand more electricity than is needed to power…\n","protected":false},"author":2,"featured_media":639834,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[20],"tags":[220,218,219,55871,5691,27796,78917,61,60,80],"class_list":["post-639833","post","type-post","status-publish","format-standard","has-post-thumbnail","category-artificial-intelligence","tag-ai","tag-artificial-intelligence","tag-artificialintelligence","tag-commission-for-regulation-of-utilities-cru","tag-data-centres","tag-eirgrid","tag-esb-networks","tag-ie","tag-ireland","tag-technology"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts\/639833","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/comments?post=639833"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts\/639833\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/media\/639834"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/media?parent=639833"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/categories?post=639833"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/tags?post=639833"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
