Title: Elsystemförordning (2026:1522) Reference: SFS 2026:1522 Department: Klimat- och näringslivsdepartementet In force: 2027-01-01, except 11 kap. 2 § and 12 kap. 1 § (2027-07-01) and the first application of 9 kap. 3 § (first tillsynsperiod starting after 31 December 2027) Language: Swedish

The government ordinance that accompanies the new elmarknadslag (2026:1281) and replaces the ordinances built on the old ellag. It is issued under the elmarknadslag’s delegations (and regeringsformen 8 kap. 7 § and 11 §), names Ei as nätmyndighet (1 kap. 5 §), and in most places gives Ei the power to issue föreskrifter rather than setting detailed rules itself. The 15 chapters cover system responsibility, operational security, unbundling, accounting, connection, transport, invoicing, revenue cap, metering, balance responsibility, supply and aggregation, energy sharing, disconnection and supervision.

Repealed on entry into force (övergångsbestämmelse 2): förordning (1995:1145) om redovisning av nätverksamhet, (1999:716) om mätning, beräkning och rapportering av överförd el, (2011:931) om planering för prioritering av samhällsviktiga elanvändare, (2018:1520) om intäktsram för elnätsverksamhet, (2022:585) om elnätsverksamhet (Source - Förordning (2022-585) om elnätsverksamhet), (2023:241) om det nationella elsystemet, and (2023:242) om leverans av el och aggregeringstjänster.

Provisions that matter for flexibility

Provision	Content
2 kap. 6–8 § — flexibility in distribution systems	A DSO drafts specifications for the flexibility services it procures and standardised market products, after consulting TSOs and other actors; submits them to Ei for approval; publishes a list once approved. Ei must approve if they ensure “faktiskt och icke-diskriminerande” participation by relevant market actors; Ei may issue föreskrifter on how the list is published
2 kap. 10–13 § — nätutvecklingsplaner	A DSO’s plan must show how the system stays efficient and meets reasonable distribution demand, state the need for flexibility services in the medium and long term, list planned investments for the next 5–10 years with emphasis on infrastructure to connect new generation and load, and account for the resources used as alternatives to grid expansion. The DSO consults TSOs and affected system users and publishes and submits an account of the responses and how they were taken into account. Ei compiles the plans and publishes the content on its website
2 kap. 14 §	Ei compiles and publishes each year the technical requirements and other conditions for providing demand flexibility
2 kap. 15–18 § — information to facilitate demand flexibility	The TSO holder publishes the renewable share and greenhouse-gas emissions of delivered electricity per elområde, with forecasts. DSOs make the same information available and must publish “anonymiserade och aggregerade uppgifter om anläggningar som skulle kunna bidra med efterfrågeflexibilitet” in their own system. Data must be digital, in a standardised format that can be read by electronic-communication equipment such as smart meters, charge points, heating and cooling systems and building energy-management systems. Ei may issue föreskrifter on where, when, at what interval and in what formats, and on how the data is calculated. The ordinance text contains no requirement on injection data from self-consumers or energy communities
2 kap. 19 §	Compensation for injection (from 2 kap. 14 § elmarknadslagen): the first component is based on the reduction in the network’s energy losses from the plant’s injection and is proportional to the amount and timing of injection; the second takes into account the plant’s power-delivery ability, its operational reliability and any agreement with the system operator on planned operating times, and the amount and timing of injection
3 kap. 17–20 §	DSO procurement guidelines for products and services must be objective, non-discriminatory and transparent, with consultation of TSOs and market actors. The TSO drafts specifications and standardised products for non-frequency ancillary services and submits them to Ei, which approves them on the same test as for DSO products
4 kap. 1–5 § — energy storage	Ei can grant an individual dispensation from the ban on system operators owning, developing, managing or operating storage, either where the storage is a fully integrated network component, or where all of the following hold: (1) after a non-discriminatory, transparent tender that Ei has reviewed and approved, no other party was granted the right to own or operate such a facility or could provide an equivalent storage service at reasonable cost or within reasonable time, (2) the storage is needed for the system operator’s duties, (3) it is not used to buy or sell electricity on retail, wholesale or balancing markets, and (4) Ei finds the exception needed and has assessed the tender. After a dispensation Ei consults publicly at least every five years (earliest two years after a grant or a consultation); if a third party could run the storage cost-effectively, Ei must decide that the dispensation ends 18 months after the consultation. A TSO dispensation is notified to the Commission and ACER. The consultation and 18-month rules do not apply (4 kap. 4 §) to fully integrated network components, or to facilities that meet all of these: owned or run by a DSO with a final investment decision before 4 July 2019 and connection by 3 July 2021, or a TSO with a final investment decision before 1 January 2025 and connection by 31 December 2026; integrated in the grid; used only for immediate restoration of grid security after unplanned events; and not used to trade electricity on retail, wholesale or balancing markets
6 kap. 2–3 §	A network user with a connection agreement that limits or controls injection or withdrawal must install an effektregleringssystem that has “på ett lämpligt sätt” been found reliable; Ei may issue further föreskrifter
6 kap. 6–8 §	A DSO publishes information on available capacity for new connections to its local and regional grid on its website, updated at least quarterly, transparent, clear and geographically detailed, covering the capacity being requested, whether a connection with a limiting or controlling agreement may be possible, and how available capacity is calculated. Before publishing, the DSO must first investigate which measures are needed to protect information it may not disclose by law (7 §); Ei may issue further föreskrifter (8 §)
9 kap. 3–4 §	The revenue cap covers costs for operation, maintenance and, where needed, expansion, including capital costs (3 § applies first to a tillsynsperiod starting after 31 December 2027). Ei may issue föreskrifter on what counts as effective use of the grid and on what is required for flexibility services to count as improving efficiency (elmarknadslagen 9 kap. 9 §)
10 kap. 33–35 § — open customer interface	Meters must have a customer interface supporting an open standard, giving near-real-time current, active and reactive power per phase for withdrawal and injection, voltage per phase and meter readings; it cannot receive information; it is activated only on the user’s request; the system operator checks identity and deactivates it on change of user, on request, or if a withdrawal point has no user
13 kap. — energy sharing	Users who receive shared electricity notify their suppliers, with the elområde of the plant and the consumption point, whether the transferor’s main activity is energy sharing, and the BRP at the injection point; a legal person also states employees, turnover and balance-sheet total, given “på heder och samvete”. Deductions are made per quarter-hour from the recipient’s measured consumption
12 kap. 24 §	Ei may issue föreskrifter on the notification an aggregation-service provider makes to the system operator

What the ordinance does not do

It sets few numbers or deadlines itself. Most detail (product specifications, DNDP contents, capacity-information format, revenue-cap methods, connection rules) is delegated to Ei föreskrifter that are not yet in Raw/ except EIFS 2026:10 (Source - EIFS 2026-10 Anslutningsavgifter för Elektriska Anläggningar (2026)) and EIFS 2026:8.

Distribution Network Development Plan — the DNDP content rules move here from förordning 2022:585
Villkorade Avtal — 6 kap. 2–3 §, 6 § (effektregleringssystem; capacity information including limited-connection options)
Ei — the many föreskrift powers and approvals it now holds
