Ei Förberedelser Sistahandsleverantör (2026)

Ei news item, 9 September 2026 — Energimarknadsinspektionen announces it has begun preparatory work ahead of the leveransskyldig sistahandsleverantör (supplier-of-last-resort) rules taking effect 1 July 2027, replacing the anvisade elhandelsavtal (assigned electricity contract) system. The substantive legal mechanism itself is not new here — it’s already covered via Source - Elmarknadslag (2026-1281) and Elmarknadslagen — this item is specifically about Ei’s transition process and timeline.

Key claims / what’s new

• Ei’s preparatory work has formally started: analysis, dialogue with affected actors, information, and other preparatory work, aimed at a well-functioning transition to the new system.
• Two named föreskrifter to come, both from Ei:
  1. How grid companies (elnätsföretag) must calculate market shares when determining which elhandelsföretag becomes the designated leveransskyldig sistahandsleverantör in an area.
  2. How that designation must be publicized.
• Legal basis (per the item): rooted in the EU electricity market directive and implemented through the new elmarknadslag (SFS 2026:1281) and elsystemförordningen (SFS 2026:1522, 12 kap.).
• Timeline: the föreskrifter are planned for publication spring 2027, ahead of the 1 July 2027 application date, to give affected actors time to prepare.
• Mechanism confirmed (consistent with the existing wiki treatment): it is the grid company (elnätsföretaget) in each area — not Ei directly — that calculates market shares and publishes which elhandelsföretag holds the sistahandsleverantör role there.
• Rationale restated: the current anvisade-avtal system reduces the risk of customers going without electricity, but has been criticized for often being pricier than other contracts and for dampening retail competition, since some customers passively rely on it rather than actively choosing a supplier.

Relevance to wiki

• Elmarknadslagen — firms up the “implementation pending” note with a concrete spring-2027 föreskrifter timeline and names what the two föreskrifter will cover.
• Source - Elmarknadslag (2026-1281) — same update, on the primary-source page.
• Regulatory Calendar — a new watch-list/dated entry for the spring-2027 föreskrifter publication, ahead of the existing 1 July 2027 in-force milestone.
