THE DATA CENTRE INTERVIEW
Why power adequacy is the gatekeeper for AI growth Behind the UK and Irish stories lies a shared reality: energy infrastructure.“ Power adequacy is the gatekeeper for AI,” Matthew explains.
Schneider Electric’ s Sustainability Research Institute highlights Adequacy Reserve Margin( ARM) as a key metric for judging whether extra demand can be absorbed without undermining system resilience. Governments set and enforce ARM targets to ensure grid stability.
“ Think of ARM as your safety buffer,” says Matthew.“ When countries keep that buffer at 15 % or more, they can bring on large AI loads with a reasonable degree of confidence. When they sit consistently below it, every new hyperscale or AI campus becomes a risk decision.”
Ireland has experienced this firsthand. Frequent dips below the 15 % mark, combined with ongoing reliance on fossil fuels, have made new largescale connections far more complex to approve and deliver.
“ In that context, you can’ t just wave through every AI project,” he says.“ You need a government-approved framework that asks: does this project help or hurt system adequacy?”
In Ireland, LEAP and the Commission for Regulation of Utilities’ updated LEU Connections Policy do exactly that by tying permissions to system impact. Planled siting, co-location with renewables and requirements for flexibility or selfsupply all push large users to support rather than strain the grid.
“ The UK isn’ t in the same position as Ireland, but the direction of travel is similar,” Matthew says.“ As AI clusters grow, adequacy-aware thinking will have to play a bigger role. It’ s far better to build that into government thinking and market signals now than to retrofit it after the fact.”
How to change burdens into assets For Matthew, the shift from seeing data centres as potential burdens to viewing them as prospective grid assets is cause for optimism. The EU’ s revised Energy Efficiency Directive, which requires operators above 500kW to report KPIs, is already nudging behaviour.
“ The days of opaque, one-way consumption are numbered,” he says.
