A broad majority in the Danish Parliament passed legislation on 1 October 2026 that ends first-come-first-served access to the national electricity grid and puts large data centres in the lowest-priority category for new connections. The law takes effect on 12 October, according to Denmark’s Ministry of Climate, Energy and Utilities.
The reform responds to a connection queue that has swollen as data centres, electrification projects and renewable generators all compete for limited capacity. A large majority in the Danish parliament passed legislation on Thursday that ends first come, first served access to the grid amid a 57 GW queue that may slow the buildout of data centres and battery storage projects. That compares with a national peak electricity demand of roughly 7 GW, according to a separate report on the plan’s August draft by The Tech Capital.
What changed
A broad majority in the Danish Parliament has adopted an emergency plan for the electricity grid, replacing the existing first-come, first-served approach to allocating constrained grid capacity. The Danish Ministry of Climate, Energy and Utilities said the legislation gives Energinet and grid companies greater scope to prioritise which projects receive access to limited electricity grid capacity.
The new framework sorts connection requests into four tiers. Category 1 covers “standard load growth for existing customers, new households, small businesses (e.g., in transport), and critical societal functions such as defense, healthcare, and emergency services, including data centers linked to critical societal functions.” Category 2 is for projects that contribute to the green transition and electrification of society, while Category 3 is for energy storage facilities. Category 4 covers large energy consumers. The ministry’s agreement states that this category “will include data centers, which are typically not geographically bound and may have consumption patterns that negatively affect the grid.”
Not every data centre lands at the bottom. Some data center projects have been included within Category 1, which will focus on “protected needs and critical societal functions.” Opposition reaction was mixed on intent versus effect: the Red-Green Alliance said the agreement would place data centres at the back of the queue while prioritising Danish homes and services including heating, public transport, healthcare and climate projects. The Alternative party said the new rules would make it possible to reject hyperscale data centres to prioritise critical societal functions and the transition away from fossil fuels.
Why it matters
The queue problem predates this bill by years. State-owned grid operator Energinet’s grid expansion had fallen so far behind schedule that it risked delaying the broader energy transition, a National Audit Office report found. The Climate Ministry had known the situation was critical for three years but acted slowly, and some 70% of projects were delayed, typically by two years. Scarce capacity has a self-reinforcing effect: pressure on the electricity grid is currently so high that in several areas there is not enough capacity to connect all projects seeking access.
The move also signals a broader policy shift in how European grid operators ration scarce network capacity between electrified industry, households and large digital loads, rather than relying purely on application order. Finland is reportedly considering a similar system.
| Field | Detail |
|---|---|
| What | Emergency grid connection law ending first-come-first-served access |
| Who | Danish Parliament; implemented by Energinet and grid companies |
| Where | Denmark |
| Scale | Connection queue of roughly 57 GW against national peak demand near 7 GW |
| Status | Adopted 1 October 2026; in force from 12 October 2026 |
What to watch
Attention now turns to how Energinet applies the four categories in practice, including which data centre projects qualify for the top tier on “critical societal function” grounds, and whether Finland or other grid-constrained European markets move toward similar priority systems.
