New Developments in UK Datacentres: The Shift to Gas-Powered Energy
In recent years, the UK has seen a dramatic increase in the number of datacentres being developed, with more than 100 new projects anticipated to rely on gas to generate electricity. This trend raises crucial questions regarding the country’s climate targets and the energy demands of burgeoning artificial intelligence (AI) technologies.
The Growing Demand for Datacentre Power
Stuart Okin, the director of cyber regulation and AI at Ofgem, highlighted the staggering amount of 100 gigawatts (GW) of datacentre projects currently in the queue for connection to the National Grid. With the wait for these connections spanning several years, many operators are left searching for alternative energy sources, significantly increasing their reliance on fossil fuels.
“Clearly that’s not all going to be able to connect to the grid,” Okin emphasized, suggesting that those unable to gain direct access to renewable energy sources might have to opt for gas instead.
Pivot to Gas: A Temporary Fix or Long-Term Solution?
The push for gas connections isn’t a passing trend; it reflects a significant shift in the energy landscape for datacentres. Silvia Simon, head of research at Future Energy Networks, revealed that over the past two years, over 100 requests for gas connections have been submitted. These requests could equate to more than 15 terawatt-hours of energy annually—enough to power London for approximately four and a half months.
As datacentre developers seek gas connections not just for resilience but as a primary supply, the underlying issue of connecting to the electricity grids grows more severe. This trend indicates a considerable plight within the industry to source sustainable power.

Global Trends: Following the US Model?
In the United States, a similar predicament exists. Many tech companies are heavily investing in AI and, in some cases, have faced community backlash over their reliance on gas-fired power generation. Notable examples include Elon Musk’s xAI, which has been criticized for operating illegally without proper permits for methane-powered generators, raising health concerns for surrounding communities.
In fact, recent reports indicated that 11 US datacentres serving companies like Meta, OpenAI, and Microsoft could produce more carbon emissions than the entire country of Morocco due to their off-grid gas generation setups. As the UK charts a similar course, the implications for environmental targets become pressing.
Permanent Reliance on Gas Power
Interestingly, the number of developers considering long-term reliance on gas has risen sharply. An energy consultant noted that requests for well over 100 megawatts (MW) of gas power on a permanent basis have become increasingly common. This shift diverges from previous strategies where gas was typically viewed as a temporary solution—largely due to carbon emissions, permitting issues, and land-use concerns.
As Julian Leslie, director of strategic planning at the UK’s National Energy System Operator (Neso), pointed out, this gas buildout poses a tricky conundrum for Britain’s climate objectives. With the aspiration to have less than 5% of unabated gas contributing to the electricity supply, the rise in datacentres powered by unabated gas complicates the path to achieving the Clean Power 2030 target.
Regulatory Challenges and Potential Solutions
Eleanor Warburton, Ofgem’s director for energy system design and development, stressed the impact of AI’s growth on energy dynamics. She noted that the system is under review for more effective connections, especially for viable projects. This reflects an acknowledgment by authorities that current grid congestion problems necessitate reevaluation.
The potential of strategic prioritization for critical projects, particularly those involving AI, is a topic currently under governmental scrutiny. This determination could indicate a shift in how datacentre projects might be integrated into the grid, offering insight into future energy infrastructure planning.
Community Concerns: A Call for Climate Awareness
Amid the frenetic growth of datacentres, voices from advocacy groups are sounding alarms. Kat Jones, director of Action to Protect Rural Scotland, harshly criticized the trajectory of hyper-scale AI datacentres. She expressed concern that developers seem detached from the urgency of climate science, suggesting that discussions around the necessity for onsite gas generation have overshadowed critical environmental considerations.
In her view, it feels as if the architectural debates for these energy-intensive installations ignore the realities of a grid already straining under the weight of energy demands.
This swift shift toward gas dependence for datacentre power in the UK, prompted by connection delays to the National Grid, brings with it a plethora of environmental and regulatory implications. As developers scramble for energy solutions to facilitate their ambitions, the balancing act between fostering innovation and meeting climate commitments remains precarious.
