Anslutningsavgift
The shallow-charge default isn't unconditional — when it would leave the grid company recovering only a small share of the true connection cost, Ei's guidance names five specific scenarios (a remote facility, disproportionate shared-network use, a limited-time facility, among others) that force a deeper charge instead, so the shortfall doesn't quietly get socialized onto everyone else's tariffs.
The new rulebook explicitly does not revive the old ellagen's fee exemption for microproduction (solar) connections — Ei found that exemption incompatible with EU law's requirement that connection charges be objective and non-discriminatory, so small solar producers lose a benefit the previous regime gave them.
For the recurring fee this one-time charge is often confused with, see Elnätsavgift — What Determines Your Bill.
Anslutningsavgift (connection fee/charge) is the one-time fee a Swedish grid company (nätkoncessionshavare) charges to connect a facility to the electricity grid — covering new connections, reconnections, and increases to a facility’s contracted power (avtalad effekt). It must be reasonable (skälig), and from 1 January 2027 its design is governed by a single, detailed nationwide rulebook — EIFS 2026:10 — replacing what had been fragmented, DSO-specific practice. The reform responds to an EU Electricity Market Regulation requirement that member states have pre-established, pre-approved methods for connection charges (Art. 18, Regulation (EU) 2019/943 as amended); Sweden’s prior regulation did not meet that bar.

The shallow-charge principle
The default rule is that the connection charge should be grund (shallow): the connecting customer pays only the customer-specific costs of measures required from the nearest transformer station the facility mainly uses and whose dimensioning it affects (existing or planned; for a lokalnät connection) or the nearest actually feeding/receiving network part owned by the nätkoncessionshavare (for regionnät/överföringssystem connections), up to the connection point itself. Costs of reinforcing the overlying grid are excluded and instead recovered collectively through transmission tariffs (överföringsavgifter) — spread across the whole customer collective rather than billed to the individual connecting customer.
Where multiple facilities share a network part, the customer-specific share is apportioned by the connecting facility’s contracted power relative to the dimensioning capacity of the shared network parts (its proportionerliga belastning) — a facility that will be the sole user of new infrastructure bears the full cost; a facility sharing reinforced capacity with others pays only its proportional slice. Existing network assets used are valued at their age-adjusted value in the capital base (kapitalbas) — the same asset-valuation concept used in revenue-cap regulation. Nätkoncessionshavare may use industry-standard schablonvärden (e.g. Energiföretagen’s EBR guidelines) to simplify the calculation.
The exception: “särskilda skäl”
The shallow-charge principle bends when it would leave the nätkoncessionshavare recovering only a small share of the true connection cost, or when other special reasons (särskilda skäl) exist — in those cases, a deeper charge is required instead, so the shortfall isn’t quietly pushed onto the wider customer collective. Ei’s guidance gives five qualifying scenarios: a remote facility requiring extensive dedicated infrastructure; a facility (remote or not) using shared network parts to a disproportionate extent; overlying-grid measures that mainly benefit neither the customer collective nor the DSO; connection to a capacity-constrained meshed network requiring extensive work; or a facility that will only be used for a limited time. The föreskrift text itself does not spell out a justification duty or an Ei prövning process specific to invoking this exception — the nätkoncessionshavare applies it based on its own assessment that the customer collective would otherwise bear a disproportionate cost share, though Ei‘s general prövning channel for connection disputes remains available to customers.
Standard tariffs for small connections
For facilities with a fuse rating (mätarsäkring) of at most 25 A, the charge is always schablon-based, built from the as-the-crow-flies (fågelväg) distance to the nearest transformer station, up to 600 m:
| Distance band | Structure |
|---|---|
| Up to 100 m | Fixed schablon fee |
| 100–600 m | Fixed 100 m fee + a schablonised per-metre rate for the remainder |
| Beyond 600 m | The above + an individually-calculated charge for the excess distance, under the general principles |
Nätkoncessionshavare with markedly uneven cost levels across their service area (e.g. rural vs. urban civil-works costs) may set different schablon values by area. Notably, the föreskrift does not revive the old ellagen’s fee exemption for microproduction connections — Ei found that exemption incompatible with EU law’s requirement that connection charges be objective and non-discriminatory.
Current (pre-2027) reference values: Ei’s existing schablon method for this tier, PM2013:03, uses a different band structure than EIFS 2026:10’s own (200/600/1,200/1,800 m rather than 100/600 m) — for 2026: 43,000 kr flat to 200 m, +369 kr/m to 600 m, +953 kr/m to 1,200 m, +562 kr/m to 1,800 m, individual assessment beyond. Whether EIFS 2026:10 inherits this cost basis (SCB survey + EBR catalogue) or recalculates independently for its own 100/600 m bands is not yet known.

Why it matters for flexibility
Anslutningsavgift design interacts with flexibility policy at two points. First, a deeper connection charge and standard flexibility/conditional-connection products are two different tools for the same underlying problem — a customer facing constrained capacity — and a DSO’s choice between “charge more to build now” and “offer a flexible/conditional connection instead” shapes how much flexibility demand actually reaches the market. Second, the shallow/deep-charge boundary determines how much of a large or awkwardly-located connection’s true cost is socialised across the customer collective via tariffs versus internalised by the connecting customer — the same cost-allocation tension that runs through revenue-cap capital-cost regulation more broadly.
For the practical consequences of this rulebook — what actually changes for DSOs redesigning their methodology and for customers connecting from 2027 — see Anslutningsavgift 2027 — What Changes for DSOs and Customers, which also covers the related RP5 (2028) revenue-cap change to how connection-fee-funded assets are treated.

Data gaps
- EIFS 2026:10’s own 100/600 m schablon figures (from 1 January 2027) — only the current PM2013:03 pre-2027 figures are confirmed; whether EIFS 2026:10 recalculates from the same SCB/EBR cost basis or independently is unknown
