Berättigad part

A berättigad part (entitled party; also called energitjänsteföretag on Edielportalen) is a recognized Swedish electricity market actor type that holds the right to access a consumer’s metering data for the purpose of providing energy services — including flexibility, demand response, and automated optimization. Operational from 1 June 2025.

Legal basis

The berättigad part concept originates from the EU Electricity Market Directive 2019/944, which requires member states to ensure that consumers can access their metering data and share it with third parties to enable energy services. The Directive’s rules on data access were binding from 5 January 2025.

Swedish national implementation rules were issued via the Mätföreskriften (metering regulation) and Ediel-anvisningen (Ediel implementation guide), entering into force 1 June 2025. These replaced the prior fullmaktshantering (power-of-attorney) model for metering data access with a standardized PRODAT message-based process.

The actor type — and the handbook’s dedicated Chapter 11 describing the operational process — were added to the Svenska kraftnät/Energiföretagen Elmarknadshandbok in edition 25B (October 2025), not 25A: 25A only added BRP and BSP as named actor types. (Source - Svensk Elmarknadshandbok 26A (2026))

What berättigad part enables

A berättigad part can:

• Request ongoing metering data from any DSO for any consumer who has granted consent — at quarterly (15-minute) resolution, upgrading from the default monthly metering
• Request historical data up to three years back (or from the start of the consumer’s grid contract if shorter)
• Combine ongoing and historical requests in a single PRODAT message

This gives aggregators, flexibility platforms, and energy service companies the granular interval data they need to:

• Build baseline consumption profiles for flexibility verification
• Identify DR opportunities and activate flexibility resources
• Automate optimization of heat pumps, EV charging, batteries, and other flexible assets

Process

Registration prerequisites

1. Sign an Ediel-avtal with Svenska kraftnät — establishes the actor’s identity in the Swedish market with a unique Ediel-id
2. Pass Ediel tests on Edielportalen (the role is labelled energitjänsteföretag there)
3. Sign a bilateral agreement with each DSO where customers are located — one agreement covers all customers within that DSO’s area. Energiföretagen Sverige provides a standard template

Per-customer flow

If the consumer does not act within 21 days, the DSO sends a timed-out rejection (Z14 with status A76). If the consumer actively declines, the DSO sends Z14 with withdrawn status (A13).

Termination

• Berättigad part terminates: sends PRODAT Z18; DSO confirms with Z15 (Termination B80)
• Consumer revokes: contacts DSO directly; DSO sends Z15 (Revocation B79) to berättigad part
• Consumer moves out: DSO sends Z15 (E37 — no valid grid access contract) the day after move-out date

DSO billing

DSOs are required by law (ellagen) to charge berättigad part for each transaction handled: initiating access, ongoing reporting, and termination. Fee levels are set by each DSO and must be published. The result is a per-customer, per-DSO cost that berättigad parts must factor into their business models when aggregating across many small customers spread across multiple DSO areas.

Fees must be cost-reflective (Ei tillsyn, June 2026): After finding large price differences between DSOs (March 2026), Ei concluded a supervision of meter-value-access fees in June 2026. The fee must be kostnadsriktig — it may include only costs directly tied to providing access, not costs from inefficient routines, system deficiencies, or other ongoing operations; included personnel cost must reflect the competence the task actually requires. Explicitly, the fee must not be designed so it obstructs access to meter values or the development of efterfrågeflexibilitet — Ei treats well-calibrated fees as a precondition for energy services and flexibility to develop. Of 8 DSOs reviewed, Jämtkraft Elnät AB was ordered to lower its fee and report the new level by 30 September 2026; the other seven cases were closed, but Ei stressed all DSOs have an ongoing duty to review their fees.

Significance for flexibility

The berättigad part mechanism is the formal operational gateway for aggregators and flexibility service providers needing granular consumption data:

• Before June 2025: meter-value reporting to third parties ran on power-of-attorney (fullmakt) handling, which the handbook says was replaced by PRODAT messages from 1 June 2025
• From June 2025: standardized PRODAT process, consumer consent via Mina sidor, DSO obligation to respond and deliver

The quarterly resolution upgrade is especially significant: without 15-minute interval data, aggregators cannot accurately verify flexibility delivery, run baselines, or participate in products with sub-hourly settlement. The berättigad part mechanism addresses this data barrier at the infrastructure level, though per-DSO agreements and fees remain (see above).

For the Elmarknadshubb context: berättigad part is a partial solution within the existing Ediel infrastructure. It enables data sharing but requires bilateral agreements with each of Sweden’s 168 DSOs — the transaction cost is non-trivial for a new entrant with a geographically scattered customer base. The future DHV/FIS data infrastructure aims to reduce this friction by centralizing data access.

Relationship to other actors

Data gaps

• How many actors have registered as berättigad part / energitjänsteföretag since June 2025 — no public registry found
• Whether the new Elmarknadslag (Prop. 2025/26:240, in force Jan 2027) changes the berättigad part framework materially — it introduces BSP/BRP as legal roles which may affect data access architecture
