Key claims / what’s new

• SFS number assigned: the law (per Ei/other sources, not stated in the statute text: adopted by the Riksdag 15 June 2026, Prop. 2025/26:240) is promulgated as SFS 2026:1281, utfärdad 2026-06-18, in force 1 Jan 2027 (sistahandsleverantör provisions, 12 kap. 4–6 § and 11 kap. 26–32 §, from 1 July 2027).
• Terminology change — systemansvarig. Nätföretag is replaced by systemansvarig (per the news/proposition framing — the statute text itself defines only the new terms and does not mention the old ones), clarifying that companies running nätverksamhet also carry a system responsibility, not just line ownership. Exception: companies holding only a nätkoncession för linje whose line(s) are used for injection or withdrawal by only one customer within the same koncern. The term transmission is replaced by överföring.
• BRP/BSP in statute. Definitions adopt the EU terms: balansansvarig part (per Art. 2.14 EU Electricity Market Regulation) and leverantör av balanstjänster, replacing the single balansansvarig (ch. 11). Statutory definitions also include aggregering, aggregeringstjänst, efterfrågeflexibilitet, dynamiska elpriser, delad el, distributionssystem, etc. (1 kap. 5 §).
• Dedicated chapters for Aggregeringstjänster (ch. 13) and Energidelning (ch. 14) — the first time aggregation services and energy sharing have their own statutory chapters in Swedish electricity law.
• Anvisade elavtal abolished → leveransskyldig sistahandsleverantör (ch. 12): from 1 July 2027 the sistahandsleverantör (12 kap. 4 §) must, on request, deliver electricity at the user’s withdrawal point against payment — only for users with expected annual consumption below 100 000 kWh (the statute states no right to require financial security; an earlier version of this page said so, unsupported). The designated supplier is the one with the largest market share within an area covered by a lokalnät intäktsram, measured over twelve months of delivered electricity to users below 100 000 kWh. It takes over on a supplier’s bankruptcy or loss of balansansvar (11 kap. 22–23, 26–28 §) only after the 10-business-day (max 15 calendar days) restoration period under 11 kap. 22 § has run out or restoration is barred under 23 §; contract-less customers pay under its terms with max 14 days’ notice (11 kap. 29, 31 §). The “anvisade elavtal abolished / must actively sign” wording is interpretation, not statute text.
• Energidelning (ch. 14): renewable electricity may be shared with users at other premises, deducted from measured consumption by the elleverantör (14 kap. 6 §) — conditions: the facility is owned/leased/rented by the user or the right transferred to them (1 kap. 5 §), the transferor does not have energy sharing as main business (14 kap. 1 §), large enterprises capped at 6 MW (14 kap. 2 §), a supply contract is required (14 kap. 4 §), terms may not be worse (5 §), billing rules (17 §). Ch. 14 says nothing on how grid companies may charge (the earlier claim was unsupported); balansansvar appears only in 14 kap. 6 § point 4 (no deduction if nobody has taken balansansvar for the injection point).
• Implementation pending: full application requires several government förordningar (forthcoming) and Ei is expected to receive multiple bemyndiganden; a large number of föreskrifter will be updated for new references, terminology, and substance.
• Sistahandsleverantör transition underway: Ei announced (9 Sep 2026) it has begun preparatory work for the 1 July 2027 sistahandsleverantör switch — analysis, stakeholder dialogue, information. Two föreskrifter are planned for spring 2027: how grid companies calculate market shares to determine the designated supplier per area, and how that designation is publicized.
