Summary

Ei’s centralized mapping service aggregating key DNDP data from all Swedish DSOs that have published Distribution Network Development Plans (nätutvecklingsplaner) under the mandatory EIFS 2024:1 framework. The data is publicly available via Ei’s karttjänst (map tool) and downloadable as Excel. This dataset provides the broadest available cross-DSO view of Swedish grid forecasts, investment plans, flexibility needs, and adequacy assessments.

The dataset has four sheets covering the four primary DNDP content categories. It is the primary public source for system-wide comparisons of Swedish DSO planning data. Its most significant limitation is inconsistent methodology: DSOs have interpreted the reporting format differently, mixing MW and MWh, using ranges vs. point estimates, and applying different geographic disaggregation schemes.

Data structure: four sheets

Sheet 1 — Behovet av överföringskapacitet (Capacity forecasts)

Annual consumption/production need in MW, 2025-2034, per DSO (and sub-area). Approximately 155 reporting entities. Most small-to-medium DSOs report single peak MW values. Large complex DSOs (E.ON, Vattenfall, Ellevio) use structured formats: Höglast/Låglast, Förbrukning/Produktion, or range formats, broken down by county or internal sub-area.

Key entries:

  • E.ON Energidistribution: reported by county as höglast (peak demand); Skåne is by far the largest area at ~2,921 MW höglast in 2025
  • Vattenfall Eldistribution: reported by area (Norr, Mellan, Stockholm, Öst, Väst) as “Förbrukning regionnät” + “Förbrukning lokalnät” + “Produktion”
  • Göteborg Energi Nät: 567 MW (delområde A, 2025) growing to 951 MW (2034)
  • Luleå Energi Elnät: 209 MW (2025) → 246 MW (2034) — modest growth in this snapshot (note: Luleå’s capacity need for flexibility is 305 MW/yr by 6-10yr horizon, far exceeding this base)

Sheet 2 — Planerade investeringar (Investment plans)

Binary yes/no per DSO sub-area: does the DNDP contain planned investments? Nearly universal “Ja” among reporting DSOs, with a few exceptions (typically very small DSOs with no investment activity).

Sheet 3 — Behov av flexibilitetstjänster (Flexibility needs)

Reported in MW per DSO/sub-area, across three time horizons:

  • 0–2 years
  • 3–5 years
  • 6–10 years

Critical finding — Vattenfall N/A: Vattenfall Eldistribution reports N/A for all five areas across all three horizons. This is not a data gap or reporting error — it is a deliberate policy stance documented in the main DNDP: Vattenfall explicitly states that market-based flexibility services are not viable at any of its constrained locations and sees no need for flexibility solutions other than villkorade avtal. See Source - Vattenfall Eldistribution Nätutvecklingsplan 2025-2034 for the full explanation.

Luleå Energi (10 → 85 → 305 MW/yr across the three horizons) is among the most dramatic growth trajectories in the entire dataset — driven by Norrbotten industrial electrification (LKAB, Hybrit-related steel, data centers). Note Luleå uses MW/yr units rather than the more common MW, reflecting an energy throughput rather than peak capacity framing.

Göteborg Energi delomr. A (0–100 MW rising to 160–240 MW in later horizons) represents the largest reported flexibility need of any Swedish DSO area outside E.ON’s Skåne — reflecting Gothenburg’s significant industrial and port electrification.

Reporting inconsistency: The unit and format variations (MW vs MWh, ranges vs point estimates, annual vs peak, per-substation vs aggregated) make cross-DSO comparison difficult. This inconsistency is a known issue that the FNA 2026 standardization (FNAM Tabell 15) is designed to address for the next cycle.

Sheet 4 — Möter åtgärderna behovet (Adequacy assessment)

Two yes/no questions per DSO/sub-area:

  1. Do planned measures meet the need in the DSO’s own network?
  2. Are there limitations in the overlying network?

Response categories: Ja / Nej / Delvis, se nätutvecklingsplan / Det kan finnas / Otillräcklig information / N/A

Vattenfall adequacy:

AreaOwn networkOverlying stamnät
ÖstJaNej
MellanJaDet kan finnas
VästDelvis, se nätutvecklingsplanJa
NorrJaDelvis, se nätutvecklingsplan

Vattenfall’s own network meets need in almost all areas; the overlying stamnät is the binding constraint in Stockholm (Nej), Öst (Nej), and Väst (Ja = confirmed constraints).

E.ON’s own network does not meet need in five counties — Skåne, Jönköping, Kalmar, Kronoberg, Stockholm. These are the areas with active or planned flexibility markets.

Resolves data gaps

Key insights

  • Concentration of stated flexibility needs: E.ON and Göteborg Energi dominate reported flexibility needs among DSOs with active procurement strategies. The total stated needs from these two DSOs alone substantially exceeds all other DSOs combined.
  • The two-camp structure: Swedish DSOs split into two camps — those reporting quantified flexibility needs (E.ON, Göteborg Energi, Ellevio, ~25–30 others) and those reporting N/A or zero (Vattenfall and the majority of smaller DSOs). This structure is more visible in Ei’s data tool than in any single DNDP.
  • Luleå outlier: Luleå Energi’s 305 MW/yr in the 6–10 year horizon is extraordinary for a DSO of its size (~246 MW base load in 2025). If realized, it would require flexibility resources equivalent to its current total load — driven entirely by Norrbotten’s industrial transformation.
