Finland is the only Nordic country without a capacity mechanism — a structural instrument that ensures generation capacity remains available during extended stress events. WP-015 identifies this absence as a key driver of elasticity collapse risk in the 2027–2030 window. This log tracks the decision timeline.
| Date | Event | Source |
|---|---|---|
| 2021–2022 | Finland's strategic power reserve (tehoreservi) phases out. No replacement mechanism introduced. Market-based adequacy assumed sufficient. | Fingrid / TEM |
| 2023-Q3 | Orpo government coalition agreement explicitly mentions capacity mechanism. First policy-level acknowledgment that market alone may not ensure adequacy. | Government Programme 2023 |
| 2023-Q4 | WP-015 precursor analysis identifies 2027–2030 as first full-stack stress test window. Capacity mechanism absence flagged as structural vulnerability. | ACI WP-015 §6 |
| 2024-Q3 | Finnish Energy (Energiateollisuus) publishes position paper on capacity mechanisms. Supports market-wide mechanism; warns against distorting existing investments. | Energiateollisuus 2024 |
| 2025-Q1 | Fingrid confirms: strategic power reserve will not be procured for 2025–2027. No replacement capacity mechanism in place. System relies on market signals alone. | Fingrid 2025 |
| 2025-Q2 | Government working group proposes data centre flexibility mechanism (800 MW by 2030) as complementary tool. Does not constitute a capacity mechanism. | TEM working group 2025 |
| 2025-Q3 | EU Commission approves Sweden's strategic reserve (€300M, valid to 2035). Sweden now has a functioning capacity instrument. Finland does not. | EU Commission July 2025 |
| 2026-02 | Fingrid publishes "Sähköllä kasvua. Varmasti." action programme. States explicitly: "electricity adequacy will not be resolved by market forces alone." Calls for political decisions including capacity mechanism. | Fingrid Feb 2026 |
| 2026-04 | Government proposal expected no earlier than 2031. Two winters (2028–2029, 2029–2030) fall within WP-015's identified risk window before any mechanism could be operational. | TEM / ACI assessment |
WP-015 identifies three concurrent structural shifts that increase jump-regime probability: demand rigidification (data centres, electrification), buffer erosion (CHP decommissioning, stochastic hydro), and market residualisation (PPA penetration). A capacity mechanism addresses all three by maintaining dispatchable reserve capacity outside the spot market — precisely the instrument these shifts make necessary.
WP-001 defines the Black Period scenario as a 72–168 hour event requiring multi-day endurance capacity. Data centre backup power (minutes to hours), market demand response (seconds to hours), and Aurora Line imports (dependent on SE1 availability) do not cover this duration. A capacity mechanism is the only identified instrument calibrated to this timescale.
Finland is currently the only Nordic country without an operational capacity mechanism or strategic reserve. The comparison below documents what each country has in place.
| Country | Instrument | Status | Duration coverage |
|---|---|---|---|
| Sweden | Strategic reserve (effektreserv) — EU-approved €300M, valid to 2035. Svenska kraftnät also proposing market-wide capacity mechanism for long term. | Operational | Hours–days (peak power reserve) |
| Norway | Statnett has statutory obligation to ensure adequacy at all times — can mandate production, require balancing market participation, impose load shedding. Structural tool rather than market mechanism. | Operational | Continuous TSO obligation |
| Denmark | Energinet operates within EU framework with reserve obligations. Strong interconnection to Germany and Norway provides structural adequacy buffer. | Operational | Market + interconnection |
| Finland | Strategic power reserve (tehoreservi) phased out 2021–2022. No replacement in place. Capacity mechanism working group established 2023, government proposal expected 2031. | Not in place | Gap: 2022–2031+ |
Note: Sweden's strategic reserve covers peak power situations (hours). Nordic regional power surplus is projected to fall from 53 TWh in 2026 to 29 TWh by 2030, tightening adequacy across all countries. According to Svenska kraftnät's adequacy assessments, Sweden risks not meeting its reliability standard of one hour of power shortage per year within a few years — even with its reserve in place. Finland faces this without any instrument.
| Identified Need | Decision Timeline | Gap |
|---|---|---|
| 72h+ endurance capacity instrument WP-015 §6 · WP-001 §3 |
Government proposal 2031 Operational: 2032–2033 at earliest |
3–4 winters inside risk window (2027–2030) with no instrument in place |
| Nordic peer parity Sweden, Norway, Denmark all have instruments |
No target date stated | Finland structurally exposed relative to neighbours |
| Energy-dimensioned (not just power-dimensioned) reserve WP-001: Black Period = 168h |
Not yet in scope of any current proposal | Design gap: existing proposals address peak power, not multi-day energy |
Active. This log will be updated upon: government proposals, Fingrid adequacy assessments, parliamentary decisions, or significant WEM threshold events (EPP ≥ 0.50).
When the decision is made — or when the risk window closes without a decision — this log will be marked Concluded with a final assessment entry.
