Sweden

Overview

AttributeValue
SSS Relevance⭐⭐⭐⭐ Very High
Market TypeLiberalized (Nord Pool)
Key Clean ResourcesHydro (38%), Nuclear (29%), Wind (23%)
EAC SystemSwedish GO Registry (Cesar)
Grid Carbon Intensity~20-40 gCO2/kWh (one of world's lowest)

Sweden operates one of the world's cleanest electricity grids, with approximately 98% fossil-free generation. The combination of substantial hydropower and nuclear capacity makes Sweden an excellent SSS jurisdiction.

SSS Relevance

⭐⭐⭐⭐ Very High — Sweden offers exceptional SSS potential due to:

  • Operating nuclear fleet (6 reactors, ~7 GW) providing ~29% of generation
  • Massive legacy hydro (~38% of generation, 65+ TWh)
  • 98% fossil-free grid — extremely low residual mix carbon intensity
  • Mature GO system via AIB Hub
  • Pro-nuclear policy shift — government supports new nuclear development

SSS-Eligible Resources

Resource TypeCapacity/OutputSSS Classification
Nuclear~7 GW, ~50 TWh (29%)✅ Clearly SSS — default delivered baseload
Legacy Hydro~16 GW, ~65 TWh (38%)⚠️ Much participates in GO market; residual portion SSS-eligible

Operating Nuclear Plants:

  • Forsmark 1, 2, 3 (3,270 MW total)
  • Ringhals 3, 4 (2,210 MW total)
  • Oskarshamn 3 (1,400 MW)

Note: Sweden reversed its nuclear phase-out policy. New nuclear construction is now supported by government policy.

Market Structure

Regulator: Energimarknadsinspektionen (Ei)

Market Model: Liberalized, integrated into Nord Pool (Nordic electricity market). Four price zones (SE1-SE4) within Sweden.

Grid Operator: Svenska kraftnät (Swedish TSO)

Major Utilities:

  • Vattenfall (state-owned), Fortum, E.ON, Uniper
  • Many municipal utilities

Clean Energy Policy

PolicyStatus
Climate TargetNet zero by 2045
Electricity Target100% renewable by 2040 (revised to include nuclear)
Nuclear PolicySupportive — new build authorized, SMR interest
ElcertifikatSwedish-Norwegian joint certificate system (closed 2035)

Policy Shift: In 2023, Sweden's government declared support for new nuclear construction and removed the cap on reactor numbers.

EAC Infrastructure

Primary System: Cesar (Swedish GO Registry) operated by Energimyndigheten

AttributeDetails
Registry OperatorEnergimyndigheten
StandardEU Guarantee of Origin
AIB Member✅ Yes — participates in AIB Hub
ScopeRenewables, nuclear (limited), high-efficiency CHP

Residual Mix: Published by Energimyndigheten. Extremely low carbon intensity due to hydro/nuclear base.

Important for SSS: Sweden's residual mix after GO retirement is already very clean. Both nuclear and untracked hydro contribute to an exceptionally low supplier-specific emission factor.
