Data centers to be expanded across UK as concerns mount
Data centers are giant warehouses full of powerful computers used to run digital services from movie streaming to online banking - there are currently an estimated 477 of them in the UK.
Construction researchers Barbour ABI have analysed planning documents and say that number is set to jump by almost 100, as the growth in artificial intelligence (AI) increases the need for processing power.
The majority are due to be built in the next five years. However, there are concerns about the huge amount of energy and water the new data centres will consume.
Some experts have warned it could drive up prices paid by consumers.
More than half of the new data centres would be in London and neighbouring counties.Many are privately funded by US tech giants such as Google and Microsoft and major investment firms.A further nine are planned in Wales, one in Scotland, five in Greater Manchester and a handful in other parts of the UK, the data shows.While the new data centres are mostly due for completion by 2030, the biggest single one planned would come later - a £10bn AI data centre in Blyth, near Newcastle, for the American private investment and wealth management company Blackstone Group.It would involve building 10 giant buildings covering 540,000 square metres - the size of several large shopping centres - on the site of the former Blyth Power Station.Work is set to begin in 2031 and last for more than three years.Microsoft is planning four new data centres in the UK at a total cost of £330m, with an estimated completion between 2027 and 2029 - two in the Leeds area, one near Newport in Wales, and a five-storey site in Acton, north-west London.And Google is building a data centre in Hertfordshire, an investment worth £740m, which it says will use air to cool its servers rather than water.By some analyses, the UK is already the third-largest nation for data centres behind the US and Germany.The government has made clear it believes data centres are central to the UK's economic future - designating them critical national infrastructure.But there are concerns about their impact, including the potential knock-on effect on people's energy bills.It is not known what the energy consumption of the new centres will be as this data is not included in the planning applications, but US data suggests they are can be considerably more powerful than older ones.Dr Sasha Luccioni, AI and climate lead at machine learning firm Hugging Face, explains that in the US "average citizens in places like Ohio are seeing their monthly bills go up by $20 (£15) because of data centres".She said the timeline for the new data centres in the UK was "aggressive" and called for "mechanisms for companies to pay the price for extra energy to power data centres - not consumers".According to the National Energy System Operator, NESO, the projected growth of data centres in Great Britain could "add up to 71 TWh of electricity demand" in the next 25 years, which it says redoubles the need for clean power - such as offshore wind.Bruce Owen, regional president of data centre operator Equinix, said the UK's high energy costs, as well as concerns around lengthy planning processes, were prompting some operators to consider building elsewhere."If I want to build a new data centre here within the UK, we're talking five to seven years before I even have planning permission or access to power in order to do that," he told BBC Radio 4's Today programme."So you're starting to see some of these AI workloads move into other countries, where the UK has always been a very important hub."UK deputy prime minister Angela Rayner has overturned some local councils' rejection of planning permission for data centres, citing their importance to the country's infrastructure and the government's growth push.There are also growing concerns about the environmental impact of these enormous buildings.Many existing data centre plants require large quantities of water to prevent them from overheating - and most current owners do not share data about their water consumption.Stephen Hone, chief executive of industry body the Data Centre Alliance, says "ensuring there is enough water and electricity powering data centres isn't something the industry can solve on its own".But he insisted "data centres are fixated with becoming as sustainable as possible", such as through dry-cooling methods.Such promises of future solutions have failed to appease some.In Potters Bar, Hertfordshire, residents are objecting to the construction of a £3.8bn cloud and AI centre on greenbelt land, describing the area as the "lungs" of their home.And in Dublin there is currently a moratorium on the building of any new data centres because of the strain existing ones have placed on Ireland's national electricity provider.In 2023 they accounted for one fifth of the country's energy demand.Last month, Anglian Water objected to plans for a 435-acre data centre site in North Lincolnshire. The developer says it aims to deploy "closed loop" cooling systems which would not place a strain on the water supply.The planning documents suggest that 28 of the new data centres would be likely to be serviced by troubled Thames Water, including 14 more in Slough, which has already been described as having Europe's largest cluster of the buildings.The BBC understands Thames Water was talking to the government earlier this year about the challenge of water demand in relation to data centres and how it can be mitigated.Water UK, the trade body for all water firms, said it "desperately" wants to supply the centres but "planning hurdles" need to be cleared more quickly.Ten new reservoirs are being built in Lincolnshire, the West Midlands and south-east England.A spokesperson for the UK government said data centres were "essential" and an AI Energy Council had been established to make sure supply can meet demand, alongside £104bn in water infrastructure investment. — BBC

Trump set to meet Putin in push for Ukraine peace
WASHINGTON – US and Russian officials will converge on the state of Alaska ahead of a highly anticipated Friday meeting between Presidents Donald Trump and Vladimir Putin. The pair will meet for the first time in six years, as Trump tries to enact a key campaign pledge to end Russia's war in Ukraine. The US president, who has portrayed himself as a global peacemaker, hopes to leverage his personal relationship with Putin to achieve a ceasefire breakthrough where others have failed. On Thursday he assessed there was a "25% chance" the meeting would not be successful. Ukraine's leader Volodymyr Zelensky has been excluded from the talks, and warned that any resolutions made in his absence will be meaningless. In Anchorage there are few signs of the impending high-stakes meeting, except for the international media that have descended on the are rubbing elbows with holidaymakers from the "lower 48" states on visits to the Alaskan wilderness during the height of the tourist meeting between the two leaders will take place entirely on a nearby US military base – a reflection of security concerns and the relative brevity of the planned sit-down, currently scheduled to last just a few summit comes exactly one week after Trump's deadline for Russia to reach a ceasefire or face tough new was always highly unlikely that Kyiv and Moscow – who have been locked in a bloody war since Russia launched its full-scale invasion of Ukraine in 2022 – would reach an agreement to end hostilities before that was scepticism about whether Trump would stand by his threat of imposing sanctions on countries that do business with Russia, which would have resulted in a blistering trade war with China. He has, however, gone as far as to say he will impose secondary tariffs on India later this month over its purchases of Russian week's announcement that Trump and Putin would meet had the effect of tacitly pausing the sanctions countdown – and awarding both sides more time to think about their next the week, the American approach to the aims and hopes for the summit has been varied – shifting from the positive, to the cautious, to the the latter extreme, Trump has threatened "very severe consequences" if his Russian counterpart does not agree to end the war. What seemed to harden his approach was a group call on Wednesday with European leaders including the other hand, Kyiv will have been alarmed when Trump mooted the "swapping of territories" and the White House indicated that the president would take a passive approach by treating the meeting as a "listening exercise".All the while, the Russians have remained mostly silent – refusing to engage with speculation and rumours of frozen frontlines, territorial exchanges or minerals deals between Moscow and is consistency in that silence. Whenever Kremlin officials have spoken this week, it has been to reiterate Putin's seemingly intractable position on the have restated that the war will only end once Russia gains full sovereignty over the Ukrainian regions it partially occupies – Donetsk and Luhansk, known as the Donbas, as well as Kherson and Zaporizhzhia – and a pledge that Kyiv will demilitarise and not join Nato, the military alliance of Western Trump seems convinced that the usually convivial relationship he has cultivated with Putin could help him unlock a deal to end the conflict and further his image as a global issue has become central to the question of what Trump has delivered on the world stage since returning to the US presidency. He has a domestic audience to keep happy, and many of his supporters backed him for his pledge to swiftly end the war and disentangle America from expensive foreign conflicts more of the summit – his first meeting with Putin for six years – the American hopes that his negotiating style will pay dividends where other efforts to end the war have top officials have stressed the importance of him meeting Putin in person, and Trump himself has talked up his business-like instincts, saying he may know "in the first two minutes... exactly whether or not a deal can be made".Europe finds itself in the unenviable position of being caught between the two sides and excluded from Friday's their last-minute call with Trump on Wednesday, European leaders emerged tentatively optimistic that once in Alaska the US president would fight their Ukraine itself, they have endured several turbulent months, during which Trump had a memorable White House bust-up with Zelensky and later temporarily paused military supplies for Kyiv – a markedly different stance to his predecessor Joe has been sidelined ahead of Friday, protests by the Ukrainian leader that any agreement struck by Trump and Putin without input from Kyiv would amount to "dead decisions", it became increasingly clear as the week progressed that the US-Russia meeting would remain a bilateral he was careful to keep Trump onside, Zelensky felt he had to intervene after the US president's throwaway comments about the need to see "some swapping, changes in land" between Russia and Ukraine."We will not withdraw from the Donbas. We cannot do that," the Ukrainian president said, with a hint of exasperation, as speculation over potential territorial concessions reached a height on Tuesday."Everyone forgets the first part: our territories are illegally occupied. For the Russians, the Donbas is a bridgehead for a future new offensive," he said, arguing that he would "pave the way" for further conflict on its soil if he gave up the many of his compatriots, Zelensky is convinced that Putin wants to destroy Ukraine's sovereignty and people, and believes any concession to Russia would result in renewed and perhaps fatal aggression in the near is why he has consistently pushed to be invited into the room with Trump and this will not be the case during Friday's summit, the US president has pledged to update Zelensky soon afterwards – and has indicated he is angling for a "quick" three-way meeting in the near Putin would have to gain from such a meeting is unclear. The Kremlin has always said Putin and Zelensky have no reason to meet until much further down the negotiating that could still be far off. Ultimately, Putin's "central objective lies in obtaining... the geopolitical 'neutralisation' of Ukraine," according to analyst Tatyana Stanovaya."It is extremely difficult to convey what is truly at stake... as people often simply cannot accept that Putin might want so much – and be serious about it. Unfortunately, he can."The frenzied lead-up to the Alaska summit has revealed that if Trump's position on a potential resolution of the conflict is still subject to change, Putin's is will offer them a meeting place; common ground at the negotiating table may be harder to find. – BBC

Armenia, Azerbaijan sign US-brokered peace roadmap to end decades of conflict
WASHINGTON — Armenia and Azerbaijan signed a US-brokered peace 'roadmap' on Friday that US President Donald Trump said will end decades of conflict between the South Caucasus neighbors. 'With this accord, we've finally succeeded in making peace,' Trump told reporters in the State Dining Room, flanked by Azerbaijani President Ilham Aliyev and Armenian Prime Minister Nikol Pashinyan. He said the deal commits both countries to end all fighting, open commerce, travel, and diplomatic ties, and respect each other's sovereignty and territorial integrity. A key component of the agreement is the development of the Trump Route for International Peace and Prosperity (TRIPP), a corridor linking mainland Azerbaijan with its Nakhchivan Autonomous Republic through Armenian territory. Trump described it as an 'exclusive partnership with the United States' that could last up to 99 years, with major infrastructure investment from American companies. The deal also lifts US restrictions on defense cooperation with Azerbaijan. 'This is incredibly positive news for the future of the entire region,' Trump said. Aliyev called the signing a 'historic day,' saying it would 'turn the page on standoff, confrontation, and bloodshed.' Pashinyan said it marked a 'new era' based on mutual respect for sovereignty and territorial integrity. US Secretary of State Marco Rubio hailed the accord as 'an opportunity for both countries to move forward and unlock the economic potential of the South Caucasus.' The White House described TRIPP as a multimodal transit route, similar to previous proposals for the Zangezur Corridor, but under a US-led development framework. Negotiations over its operation are set to begin next week, with nine potential operators — including three American firms — expressing interest. Working groups will begin detailing the roadmap in the coming months, and the leaders signed a joint letter urging the Organization for Security and Cooperation in Europe to dissolve its Minsk Group, which for decades sought to mediate the conflict. Armenia and Azerbaijan have fought multiple wars since the late 1980s, most recently in 2023 when Azerbaijan reclaimed the Karabakh region. — Agencies
