From 2.5% of Demand to a 2035 Grid Stress Test
Across Europe, compute power demand is moving from a niche load to a macro utility issue. According to Moody’s, as reported by The Register, data centres accounted for a low single-digit share of electricity in most of Europe’s largest markets in 2025, typically about 2.5%. That baseline is set to climb rapidly: by 2035 data centres are expected to represent at least 5.7% of electricity demand in France and the UK, according to Moody’s as reported by The Register.
In smaller or more concentrated hubs, the numbers are far steeper. Moody’s, as reported by The Tech Capital, projects data centres could account for 17% of Dutch and 30% of Irish electricity consumption by 2035. As The Register’s coverage of Moody’s notes, Ireland is already an outlier: data centres made up 23% of its electricity use in 2025, up from 5% in 2015.
Meanwhile, continental ambitions remain high. According to The Register’s report on the Moody’s analysis, the EU aims to more than triple its data-centre capacity within five to seven years and shift projects to secondary markets such as the Nordics and southern Europe.
Transmission Finances, Consumer Bills and Policy Pushback
Rapid load growth creates a timing mismatch for utility balance sheets. Moody’s warns, as reported by The Tech Capital, that grid operators are exposed to financial pressure before they can recover the cost of new infrastructure. In particular, transmission networks face more strain than distribution networks because data-centre operators typically pay only for their own grid connection, per Moody’s as reported by The Register.
Households and voters could feel the knock-on effects. According to Fuse Energy’s coverage, Moody’s expects the boom to raise consumer energy bills and prompt government intervention. Some jurisdictions have already tightened the rules: as reported by The Register, Ireland now requires operators requesting 10 MVA or more to supply matching generation or storage nearby and meet at least 80% of annual demand through additional Irish renewable projects. Looking ahead, Moody’s says, as reported by The Register, that interventions could escalate to electricity price caps, additional taxes or levies, while the UK government is considering a fee for grid connection requests.

What This Means for Algeria
The Algeria hook is indirect: Moody’s analysis focuses on European electricity markets and EU capacity targets. However, for Algerian energy and telecom planners—especially anyone evaluating whether North Africa can complement constrained European hubs—the findings offer three direct policy lessons.
1. Price upstream transmission upgrades into data-centre connection terms
In Europe, transmission networks face more strain than distribution networks because data-centre operators typically pay only for their own grid connection, leaving grid operators under financial pressure before recovering infrastructure costs. Algerian utility rules can avoid that gap by requiring large compute loads to contribute to upstream transmission reinforcement.
2. Adapt Ireland’s 10 MVA threshold for matching generation and storage
Ireland now requires operators requesting 10 MVA or more to provide matching generation or storage nearby and cover at least 80% of annual demand with additional renewable projects. Setting a clear megavolt-ampere threshold in Algeria would protect the national grid as facilities scale.
3. Shield household electricity bills from compute-driven grid costs
Moody’s warns that rising data-centre demand could lift consumer energy bills and trigger price caps, taxes or levies. Ring-fencing industrial compute infrastructure costs from residential tariffs from day one prevents political and regulatory backlash later.
The Bigger Picture
Europe wants to more than triple its data-centre capacity within five to seven years and steer projects toward secondary markets such as the Nordics and southern Europe. Yet as shares climb from about 2.5% in 2025 toward 5.7% in France and the UK, 17% in the Netherlands and 30% in Ireland by 2035, grid finance is becoming the real governor of growth.
Frequently Asked Questions
How much electricity do European data centres use today, and what does Moody’s project for 2035?
According to Moody’s, as reported by The Register and The Tech Capital, data centres accounted for a low single-digit share of electricity in most large European markets in 2025, typically about 2.5%, though Ireland was already at 23% (up from 5% in 2015). By 2035, data centres are projected to reach at least 5.7% of electricity demand in France and the UK, 17% in the Netherlands, and 30% in Ireland.
Why are European transmission networks under financial pressure from data centres?
As reported by The Register and The Tech Capital, Moody’s notes that data-centre operators typically pay only for their own grid connection, placing more strain on transmission networks than distribution networks and exposing grid operators to financial pressure before they can recover the cost of new infrastructure.
What rules are European governments introducing to manage the boom?
According to Moody’s, as reported by The Register, Ireland now requires operators requesting 10 MVA or more to supply matching generation or storage nearby and meet at least 80% of annual demand through additional Irish renewable projects. The UK government is considering a fee for grid connection requests, and Moody’s says future interventions could include electricity price caps, additional taxes or levies.
