Developers of AI datacentres plan to build on-site climate-destroying gas power stations on a huge scale to meet their energy demands, research reveals.

research → plan → demands
Datacentres planned across the US, the UK and mainland Europe have proposals to build fossil fuel plants on-site to create 181GW of gas-fired capacity because of delays to connect to national grids, according to the findings.

Datacentres → plan → findings
The research by BloombergNEF says this “speed to power” will – if the planned rollout happens – emit about 345m metric tonnes of carbon dioxide equivalent a year in the US, where 90% of on-site gas-fired power stations are planned.

% → say → stations
The report was published on Wednesday as global leaders gathered in Turkey for the 31st UN climate summit, where increasing electrification – ideally from clean sources – is a central part of discussions.
asserted
increasing → publish → discussions
However, a number of key European leaders, including from France and Germany, will not be at Cop31, instead heading to Dublin where EU leaders will hold their first dedicated AI summit on Friday.

leaders → include → Friday
Mark Daly, the head of datacentres and emerging tech at BloombergNEF, said: “The extraordinary economics around AI are making speed to power one of the most important priorities for defining constraints on datacentre developers.
asserted
speed → emerge → developers
“The climate outcome will depend not only on how much electricity these facilities use, but on how quickly grids can connect them and whether power systems add cleaner generation alongside that demand.
asserted
systems → depend → demand
By 2035, the electricity demand of AI datacentres was predicted to almost quadruple to 2,354 terawatt-hours – equivalent to 7% of global electricity demand – the report said.
asserted
report → predict → demand
AI datacentres use a massive amount of electricity to power servers and cool equipment, and to run facility systems.
asserted
datacentres → use → systems
Daly said while the developers of the future datacentres claimed their gas-fired power supplies would be temporary while they waited for grid connections, once they were online, the economics could encourage them to continue generating energy, creating a longer-term fossil-fuel lock-in risk.
uncertain
economics → say → risk
The report said ensuring new datacentres were connected to the grid was the more sustainable option.
asserted
datacentres → say → grid
Faster grid connections were crucial to limiting emissions impacts and locking in fossil fuel risk, it said.
asserted
it → limit → risk
UK planned datacentres made more than 100 inquiries in 2024-5 to connect to gas as a result of delays in securing access to the electricity grid, according to Future Energy Networks, the representative body for the UK gas networks.
uncertain
datacentres → plan → networks
For example, Wapseys Wood, Buckinghamshire and Quest Park, Bedfordshire are seeking to build their own on-site gas-fired power stations because of the long wait to connect to the grid.
asserted
Wood → seek → grid
The datacentres are among the first to be fast-tracked through the government’s nationally significant infrastructure project regime, which allows developers to rapidly deliver major infrastructure, bypassing locally elected planning authorities.
asserted
developers → track → authorities
But the use of fossil fuel power generation on site is likely to be repeated by many more UK sites after the chancellor, John Healey, gave the green light for datacentres to build and run temporary on-site fossil fuel power stations while they wait for connections to the grid, as part of a so-called datacentre covenant.
asserted
they → repeat → covenant
Oliver Hayes, the head of policy and campaigns at Global Action Plan , said: “Private gas power stations for datacentres should be a red line for any government serious about climate action, so it’s shocking to see the chancellor give them his explicit backing.
asserted
chancellor → say → backing
“No one seriously believes these gas power stations will be temporary – once they’re built, they’ll lock in high emissions for years.”
asserted
they → believe → years
