🇸🇪 Sweden

Rated by region (Tier 1-3)
Tier 1 Prime · Rated by region: Tier 1-3 (open a region below for its rating) · Outlook Stable · High confidence · how we score

Cheap, clean, open Nordic power, but the national average hides a two-tier split: the northern zones (SE1/SE2, where Meta built in Lulea) are Prime, while the constrained, import-dependent south (SE4) sits two tiers lower. This overview links to both regional ratings.

National overview. This country is rated by region for siting a large load; the sub-region ratings are the actionable ones. Rated regions: Sweden North (Lulea, SE1/SE2) · Sweden South (Malmo, SE4).

The five pillars behind the tier

Access30%70

Open and welcoming, with established northern clusters.

Availability25%75

High availability (hydro plus nuclear).

Cost25%92

Cheap power, among Europe's lowest in the north.

Momentum15%60

Moderate, real momentum.

Carbon5%99

Near-zero operational carbon (~10-40 g).

Default weights, which lean toward cost and access rather than carbon: Access 30 · Availability 25 · Cost 25 · Momentum 15 · Carbon 5. Momentum reflects the data-center build already underway, not just stated intentions.

Reliability overlay

National reliability adjustment: the five-pillar score of 78 is reduced to 76, a deduction of 2 points. A national overview carries the average of its rated regions’ reliability adjustments (Sweden North (Lulea, SE1/SE2) 0, Sweden South (Malmo, SE4) 4), because a national view has to represent all of them, not only the strongest. The region pages carry the actionable ratings and their own adjustments. Reliability is reported as five separate layers, never as one combined label, because they answer different questions and a strong answer on one does not cover a gap in another: what has actually failed on the bulk system, what a forward assessment expects of firm supply, how the local network performs, what your contract actually promises, and what your site is designed to ride through. Any one of them can cap the tier.

Historical bulk-system performance: Minor flags found

North-to-south transfer is a growing bottleneck (interzone capacity around 7,000 MW): most new wind is in the north while southern nuclear has been phased out, so the load-heavy south leans on imports in low-wind hours.

What this means: A large new load faces occasional exposure here. Monitor conditions and keep a contingency plan.

Historical utility-territory delivery performance: No reliability flags found

Forward resource adequacy (assessed): Adequacy flagged

Svenska kraftnat's analysis finds rising demand without large new flexibility becomes hard to serve from about 2035, with growing dependence on flexibility and imports at peak.

What this means: A large new load faces occasional exposure here. Monitor conditions and keep a contingency plan.

Contractual service terms: not assessed

We have not compiled what firm service actually promises here: whether it is firm, non-firm or interruptible, the conditions under which you can be curtailed, the redundancy required of you, and the transfer time behind any N-1 commitment. Treat this as an open diligence item, not as an indication that service is firm.

Ask the utility for the tariff or service agreement terms before relying on firm supply.

Designed site resilience: not applicable at market level

Utility feeds, UPS, storage, on-site generation, islanding, black start and the residual energy you still expect to lose are properties of a specific site design, not of a market. This layer only exists once there is a site, and we never assert it for you.

Confidence: Med-High. Each input is labelled as measured, modelled, or drawn from a specific event, and is framed as a risk to a prospective large new load, not as a verdict on any utility or grid operator. Forward adequacy is an assessment of what is expected, not a measurement of what has happened; it is a forecast and is labelled as one.

Data provenance and freshness

How solid the data behind this rating is, on two separate axes plus recency. Source reliability is how measured the numbers are, as opposed to triangulated or modelled. Coverage is how many of the decision-relevant data dimensions (reliability, connection, and cost) are compiled for this market. The two are kept apart because they answer different questions: a market can have strong sources on the little that is covered, or broad coverage that still leans on models. Neither grades the rating itself. The rating is a cited opinion, graded separately and falsifiably by the public track record and baseline measurement plan.

Outlook drivers

↑ Upgrade triggers

  • Build scales beyond the current Nordic clusters.
  • Continued cheap clean power attracts firm tenants.

↓ Downgrade triggers

  • Northern-grid or political limits.
  • Cold-snap demand peaks.

Evidence behind this rating

Meta runs its first non-US hyperscale campus in Sweden, on hydropower ✓ Supports the rating
2025MomentumMateriality: high

Meta's three-building Lulea campus in northern Sweden, its first hyperscale data center outside the US, runs almost entirely on Lule River hydropower and was sited for some of the lowest, cleanest electricity in Europe. That is exactly the low-cost, low-carbon, firm-supply profile behind this rating.

Every rating action is dated and explained, and the log is only ever added to, never edited. Reviews happen on a regular schedule and whenever a significant event occurs. "Affirmed" means we reviewed a development and the tier held; "Under review" means a significant item is being assessed and the rating could change.
