Svenska kraftnät press notice, “Förändrad tidtabell för nordisk anslutning till MARI” (published 2 September 2026, svk.se).
Key findings
Svk and the other Nordic TSOs are postponing Nordic connection to the European MARI balancing platform, previously planned for Q1 2027. Reason given: a necessary change to the MARI algorithm — to counteract “ologisk prisspridning” (illogical price dispersion) — will not be ready in time.
Anna Jäderström (Section Head, Balancing Markets, Svk): Svk will not connect to a European balancing platform if doing so risks operational security or the functioning of the well-established Nordic market.
New estimate: connection is now assessed as possible in September or October 2027 — no exact date set; the Nordic TSOs will jointly determine and communicate a firm date once decided.
A public “Träffa Balansmarknad” forum session (meeting #36, 17 September 2026) covers the MARI connection topic.
Relevance to existing wiki topics
| Topic | Relevance |
|---|---|
| Balancing Markets | Corrects the “Nordic TSOs planning to connect as a group in Q1 2027” claim in the PICASSO/MARI section — now Sept/Oct 2027, exact date pending |
| Nordic Balancing Model | MARI is one of the two European balancing-energy platforms (with PICASSO) the Nordic Balancing Model plans to connect to |
Site data — Site/Pages/Regulatory Calendar.md | The “2027-Q1 Nordic TSOs connect to MARI” entry needs its date corrected |
Cross-reference: this delay is very likely the outcome of the dispute the wiki already tracks — Ei issued a formal enforcement order (föreläggande) demanding Svk connect to MARI by Q3 2026, while Svk’s stated position (20 May 2026) was that connection was not possible before the proposed Nordic changes had first been implemented in MARI (Source - Elmarknadsrådet Meeting 2 May 2026). This notice is consistent with Svk’s side of that dispute prevailing in practice, though it does not explicitly reference the Ei föreläggande.
