The LeadOver 100 new datacentres in the United Kingdom are planning to burn natural gas to generate electricity, with some projects eyeing permanent on‑site generation as a workaround for prolonged grid‑connection delays.The Surge in UK Datacentre Gas RequestsStuart Okin, director of cyber regulation and AI at Ofgem, warned that “there’s 100GW of datacentre projects in the queue” and not all can be linked to the National Grid. Developers therefore “have to come up with an alternative method”.Silvia Simon, head of research at Future Energy Networks, confirmed the firm has received “more than 100” gas‑connection requests in the past two years, many asking for up to 100MW of continuous gas power.Requests total > 15 TWh of energy per year – enough to power London for roughly four and a half months.Projects represent a combined 100GW of planned capacity.The Energy Demand NumbersThe scale of the demand translates into a substantial carbon footprint if supplied by unabated gas. In the United States, similar off‑grid gas generators are projected to emit more CO₂ than the entire nation of Morocco.The Climate and Grid ImplicationsJulian Leslie, director of strategic planning at the UK’s National Energy System Operator (Neso), said the build‑out could jeopardise the Clean Power 2030 goal of keeping unabated gas below 5 % of electricity supply.Eleanor Warburton of Ofgem added that the rapid growth of AI‑driven datacentres is “affecting many aspects of life including energy”, prompting a review of demand‑connection reforms.Environmental groups, such as Action to Protect Rural Scotland (APRS) led by Kat Jones, argue the rush ignores decades of climate science and risks “climate breakdown”.The Path Forward for Policy and AI InfrastructureGovernment and regulators are considering prioritising strategic connections for AI projects while accelerating reforms to speed up viable grid links. If permanent gas generation becomes the norm, further policy measures – possibly including carbon‑pricing or mandatory emissions reporting – may be required to keep the UK on track for its net‑zero commitments.

The Misstated Emissions Developers working for Google have significantly misstated how much carbon two proposed AI datacentres will contribute to the UK’s total emissions in planning documents reviewed by the Guardian. The tech company wants to build two huge datacentres – one 52-hectare (130 acre) project in Thurrock and another at an airfield in North Weald, both in Essex. To do so, developers are required to submit planning documents calculating how much carbon these projects will emit as a proportion of the UK’s total carbon footprint. The Calculation Error In both cases, they appear to have compared one year of the proposed datacentre’s emissions with the UK’s entire five-year carbon budget, understating the significance of their emissions by a factor of five, according to experts at the tech justice nonprofit Foxglove. Google's Thurrock datacentre claimed its emissions would amount to 0.033% of the UK’s budgeted carbon footprint between 2028 and 2032, but it will actually be 0.165% of the total. The North Weald datacentre said it would emit 0.043% of the UK’s total carbon budget from 2033 to 2037, but it will actually emit 0.215% of the total. The Impact Analysis These apparent misstatements are another example of a pile-up of faulty calculations surrounding AI development and its environmental footprint in the UK. The three developments will account for more than 1% of the UK’s carbon budget in 2033, equivalent to the emissions of a mid-sized city such as Bristol. The Prediction “Google has serious questions to answer about its dubious datacentre pollution figures,” said Tim Squirrell, the head of strategy for Foxglove. “Unless they can explain themselves, it looks like they are seriously misleading the council and the public over the climate pollution their facility will cause.”
