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 was added to the Svenska kraftnät/Energiföretagen Elmarknadshandbok (edition 25A, April 2025) and Chapter 11 of the handbook now fully describes the operational process. (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

Berättigad part signs agreement with consumer
        ↓
Send PRODAT Z13 to DSO (citing consumer agreement reference)
        ↓
DSO sends APERAK (syntactic acknowledgement)
        ↓
DSO flags consent request on consumer's Mina sidor (21-day window)
        ↓
Consumer approves (or declines) via Mina sidor
        ↓
DSO sends PRODAT Z14 confirming (or denying) access
        ↓
DSO begins reporting meter data at confirmed start date

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.

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: data access required case-by-case power-of-attorney arrangements negotiated with each DSO — high transaction costs, no standardized process
• 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 eliminates this data barrier at the infrastructure level.

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 ~170 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

• Whether DSO fee structures for berättigad part transactions are consistent or highly variable — relevant for aggregator business case modelling with geographically scattered customers
• 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
