Source - Prop. 2025-26-240 Nya lagar om elsystemet (2026)

Regeringens proposition 2025/26:240 — Nya lagar om elsystemet (New laws on the electricity system). Submitted to the Riksdag April 13, 2026. In force January 1, 2027 (last-resort supplier provisions: July 1, 2027). The most significant structural reform of Swedish electricity law since ellagen (1997:857) in 1997. Proposes a new Elmarknadslag and a new Lag om elektriska ledningar to replace ellagen.

Overview of legislative structure

The ellagen is formally repealed. All other acts referencing ellagen are consequentially amended (16 separate acts).

Key provisions

5. System responsibility (Systemansvar)

• Terminology change: “systemansvarig myndighet” (system responsible authority) replaced by “systemansvarig för överföringssystem” — responsibility shifts from an authority-function to being directly held by the transmission network owner (Svenska kraftnät)
• Removes the separate role of “systemansvarig myndighet” — Svk’s legal responsibility for the national electricity system is now expressed as a direct network operator obligation rather than a government-function delegation
• New: cooperation and information exchange requirements between system operators

6. Clearer roles on the balance market

Two new roles replace the existing “balansansvarig” role:

• Balansansvarig part (balance responsible party — BRP): holds economic responsibility for balancing injection and withdrawal at a connection point
• Leverantör av balanstjänster (balancing service provider — BSP): provides actual balancing services to the TSO

This dual-role structure aligns with the EU Electricity Balancing Regulation (EB GL) and with Svenska kraftnät‘s already-implemented NBM/BSP/BRP framework.

7. Delivery of electricity (Leverans av el)

• Anvisade elavtal (assigned electricity contracts) system abolished; replaced by:
• Sistahandsleverantör (last-resort supplier): obligated supplier that customers fall back to when they have no active supply contract. Selection must be fair, transparent, non-discriminatory. In force July 1, 2027.
• Customers must have a supply contract (leveransavtal); the last-resort supplier is the safety net

8. Energy sharing (Energidelning) — Art. 15a of revised Directive 2019/944

Sweden’s transposition of the EU energy sharing right. Key design choices:

What is energy sharing? Consumption of electricity from renewable sources that:

• Is produced by a facility the customer owns, leases or rents (in whole or in part), located outside the property where the electricity is consumed; or
• Where rights to the electricity have been transferred from the producing party — provided that producing party is not primarily engaged in flexibility/energy efficiency services as a commercial activity

Only renewable electricity qualifies (wind, solar, geothermal, hydro, biomass, etc.).

Geographic scope: Energy sharing is permitted between an injection point and a withdrawal point within the same bidding zone (elområde). The government rejected proposals to restrict to concession area (Energiföretagen Sverige) or network area (Vattenfall), finding these would create unequal access without sufficient justification.

Large company limitation: Companies with >250 employees AND annual turnover >€50M or balance sheet >€43M may participate only if the total installed capacity of all facilities in the energy sharing arrangement does not exceed 6 MW. This aligns with EU Directive’s Art. 15a.5(b).

Supply contract requirement: Customers taking out shared electricity must have a supply contract with an electricity supplier for that connection point. Shared electricity is a supplement, not a replacement.

Invoice deduction: Shared electricity is deducted from the customer’s electricity invoice by the supplier. The supplier has a legal obligation to make this deduction.

No feed-in obligation: Energy sharing arrangements do not trigger mottagningsplikt (the general feed-in obligation for suppliers to accept electricity).

Organizers of energy sharing (organisatörer av energidelning): A new defined role. Organizers manage energy sharing arrangements on behalf of participants. They have defined obligations toward participants including: providing information, managing imbalance responsibility, and prohibition against treating participants worse than direct customers.

Energy sharing in the public sector: Special provisions enable public bodies to participate in energy sharing arrangements.

Proof of renewable origin: It is sufficient to show that the production facility converts renewable energy (solar, wind, etc.) to electricity — no obligation to annul guarantee-of-origin certificates for individual energy sharing transactions.

Relationship to Prop. 2025/26:16

The two propositions together complete Sweden’s transposition of Directive 2024/1711:

• Prop. 2025/26:16 (in force Jan 1, 2026): Art. 6a flexible connections, fixed-price contracts, consumer protection, demand flexibility information
• Prop. 2025/26:240 (in force Jan 1, 2027): Art. 15a energy sharing; full structural recast replacing ellagen

Relevance to existing wiki content

• Electricity Market Design Reform 2024 — closes Art. 15a energy sharing gap; updates Swedish transposition table
• Energy Communities — energy sharing rules create the legal framework for community-level renewable sharing arrangements
• Demand Response — energy sharing is a new form of explicit demand-side participation
• Balancing Markets — formal codification of BSP/BRP roles in Swedish primary law
• Svenska kraftnät — systemansvar now explicitly held by transmission network owner, not delegated to authority function
• Aggregation — BSP role in new Elmarknadslag codifies aggregator market access
• Flexibility Market — energy sharing creates a new category of distributed prosumer participation distinct from flexibility markets
