Svenska kraftnät’s system development plan (systemutvecklingsplan) for the period 2022–2031, covering the transmission grid investment program and regulatory framework applicable to grid users. Published November 2021.

Status and currency

This is an older document — published November 2021 and covering a 10-year horizon from 2022. It predates:

  • The 2022 energy crisis and its effect on Swedish grid investment priorities
  • The accelerated green industrial establishment in northern Sweden (H2 Green Steel, LKAB green steel)
  • The Verksamhetsplan 2026–2028 investment figures (which supersede this plan’s investment projections)
  • LMA2024’s scenario analysis (which supersedes older demand and scenario content)
  • The effektreserv end and strategisk reserv introduction

Primary value: regulatory framework documentation — particularly the EU network codes chapter, which provides a structured reference for all applicable EU codes with entry-into-force dates and applicability scopes.

EU network codes coverage

The plan contains an overview of the EU network codes applicable to the Swedish transmission system as of publication (November 2021), plus two codes then still in development (see “Demand-side flexibility code” below):

Connection codes

  • RfG (Requirements for Generators, Reg. 2016/631): raw describes this only in general terms (“ställer tekniska krav på de produktionsanläggningar…”) — the type A–D classification, specific frequency/voltage response requirements, and commissioning-test detail below are wiki-added general industry knowledge, not stated in this raw document
  • DCC (Demand Connection Code, Reg. 2016/1388): requirements for demand facilities and distribution networks connecting to transmission; applies to major industrial consumers and DSOs at transmission level
  • HVDC (HVDC Regulation, Reg. 2016/1447): requirements for HVDC systems and DC-connected power park modules (the “most technically demanding code for inverter-based resources” framing is the wiki’s own characterization, not stated in raw)

Operation codes

  • SO (raw’s own term — not “SO GL” — covering driftsäkerhet/system states, driftplanering/outage planning with coordinated safety analyses, and lastfrekvensreglering/reserves; raw does not include emergency/restoration procedures under this heading — that’s ER’s territory, below, and was wrongly duplicated into this entry in an earlier version of this page). Real-world regulation number: 2017/1485 (not stated in raw, whose own footnote for the adjacent EB regulation mislabels a number too — treat regulation numbers on this page as wiki-supplied, not raw-sourced)
  • ER (Emergency and Restoration): procedures for system protection schemes, blackout management, and restoration (including island operation / ö-drift); activation criteria

Market codes

  • CACM (Capacity Allocation and Congestion Management, Reg. 2015/1222): day-ahead and intraday market coupling; capacity calculation; this is the code that underpins the Nordic transition to Flow-Based Capacity Calculation
  • FCA (Forward Capacity Allocation, Reg. 2016/1719): long-term (yearly, monthly) transmission capacity products; auction procedures
  • Demand-side flexibility code — not yet adopted at publication: the raw (published November 2021) describes two network codes still in development, not yet part of “applicable” EU network codes: a cybersecurity code (further along) and a demand-flexibility code, which the raw states “is not as far along in the process and will likely be adopted at the end of 2023.” The term “NC DR” does not appear anywhere in this raw document — an earlier version of this page anachronistically listed “NC DR” alongside the eight already-adopted codes as if established at time of writing, which the raw explicitly contradicts. See Demand Response for the code’s actual, later development.

Balancing code

  • EB (raw’s own term, not “GLBE-EB” — Guideline on Electricity Balancing): harmonized balancing market rules across Europe; rules for imbalance settlement, reserve procurement, cross-border balancing exchanges; the basis for PICASSO (aFRR) and MARI (mFRR) platforms. Real-world regulation number 2017/2195 is wiki-supplied, not raw-sourced.

Transmission grid scenarios (2030–2035 horizon)

The plan included demand scenarios for 2030 and 2035 which were the then-current basis for grid investment planning. These scenarios have since been substantially revised upward in LMA2024 (for high-electrification pathways) and downward in the near-term in KMA2025 (for 2026–2030 actual load growth).

Key investment themes in the 2022–2031 plan that remain current:

  • NordSyd: identified as the dominant capacity bottleneck; four-branch reinforcement described
  • Snitt 2 (SE2–SE3) and Snitt 4 (SE3–SE4): major congestion bottlenecks
  • Reactive power: increasing need for reactive compensation as renewable share grows

Capacity mechanism context (historical)

The plan covered the effektreserv (capacity reserve) as the then-operational capacity mechanism — standby fossil units contracted by Svk for extreme scarcity events. The effektreserv was terminated in March 2025 and replaced by the strategisk reserv under Lag 2025:50. This section of the Systemutvecklingsplan is therefore superseded by Source - Svk Kraftbalansen Höst 2025.
