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 a comprehensive overview of all EU network codes applicable to the Swedish transmission system:

Connection codes

  • RfG (Requirements for Generators, Reg. 2016/631): minimum requirements for generation units connecting to the grid; type A–D classification by capacity; frequency and voltage response requirements; commissioning test requirements
  • 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 at transmission level

Operation codes

  • SO GL (System Operation Guideline, Reg. 2017/1485): operational procedures for TSOs; coordination requirements; real-time data exchange; outage planning; emergency and restoration procedures
  • ER (Emergency and Restoration, Reg. 2017/2196): 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
  • NC DR (Network Code on Demand Response): the code directly relevant to demand-side flexibility, DSO flexibility procurement, and aggregator participation; see Demand Response for detailed coverage

Balancing code

  • GLBE-EB (Guideline on Electricity Balancing, Reg. 2017/2195): 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

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.
