“Effekt-tariffer” in Sweden – how will it affect EV owners

As an EV owner, the new effekttariff (power-based grid fee) mainly means you’ll start paying (part of) your grid bill based on how high your peak power (kW) gets, not just how many kWh you used.

What changes in practice

Your grid fee typically becomes (or already is) three parts:

Fixed fee (abonnemang)
Energy/transfer fee (öre/kWh)
NEW: power/peak fee (based on your effekttoppar, i.e., how much you use at the same time) (ei.se)

Important: This is your elnätsavgift (grid company), not your elhandelspris (electricity retailer). (ei.se)

Why EV owners are affected more than average

Home charging can be one of the biggest “peak creators”:

If you charge at 11 kW while cooking, running a heat pump, dishwasher, etc., your monthly peak can jump.
Many models charge the fee based on hourly average power (kWh used in an hour ≈ kW “timmadeleffekt”). (ei.se)
The exact model differs by grid company (some use top hour, some average of top 3–5 peaks, some use time-of-day high-load windows). (ei.se)

Timing (Sweden) + Vattenfall note

Sweden-wide: grid companies are moving to effect-based tariffs; guidance and rollout has been ongoing, and the aim is that all customers will have an effect component by 1 Jan 2027. (Energiföretagen)
If your grid company is Vattenfall Eldistribution: they state broad rollout “under autumn 2026” for most local-grid customers, and that apartment customers on group tariffs aren’t affected. (Vattenfall Eldistribution)

What it means for your wallet (simple mental model)

You’ll pay more if you create high peaks during “busy” hours, and less if you spread or cap your power draw. The consumer guidance is basically: find what causes your peaks (EV charging is a classic one) and shift/limit it. (ei.se)

7 easy moves that usually help EV owners

Charge at night (common advice: lower grid load → lower peak-fee impact). (Energimarknadsbyrån)
Lower charging power in the car or wallbox (e.g., 11 kW → 3.7–7.4 kW).
- Overnight, even 3.7 kW × 8h ≈ 30 kWh (often ~150–170 km depending on consumption).
Avoid stacking loads: don’t fast-charge at home while running oven + sauna + dishwasher + tumble dryer. (ei.se)
Enable dynamic load balancing in your charger (keeps house + EV under a chosen kW cap).
Move “spiky” appliances away from typical peak times (often mornings/late afternoon; varies by grid company). (ei.se)
Watch your peaks in your grid-company portal (“Mina sidor”) or via a real-time meter display. (ei.se)
If you’re considering a home battery: it can shave peaks (charge slowly, discharge during spikes). Whether it pays off depends on your tariff design and battery cost.

Power-based grid tariffs (effekttariffer) by company — Sweden

(Focus: private customers / detached houses, since EV charging is usually most noticeable there. Note that grid prices can vary by network area/region even within the same company.)

Ellevio (private: house) — power fee already in place

Applies (per their price info): power-based subscription for houses from 1 Jan 2026.
How the power fee is calculated:

Average of the month’s three highest power peaks (hours with the highest “hourly average power”), taken from three different days.
22:00–06:00 counts as only half the peak (e.g., 10 kW → 5 kW).
Price level (house):
Power: SEK 81.25 per kW (incl. VAT).
Example in their table: 16–25 A has fixed SEK 395/month, transfer 7 öre/kWh, power SEK 81.25/kW.

➡️ EV meaning: Ellevio clearly rewards night charging (half peak), and mainly “penalizes” your top 3 peak hours if you charge while running other heavy loads (oven/sauna/heat pump, etc.).

Vattenfall Eldistribution — power fee is coming for most customers (not yet for everyone)

What they say about rollout:

Autumn 2026: Vattenfall Eldistribution will introduce a power fee for most local-grid customers (apartments on group tariffs are excluded).
They also state that all Swedish grid companies must have introduced a tariff model with a power component by 1 Jan 2027.

Already now (smaller customer group):

For a smaller group with fuse subscriptions 16–63 A who get the power fee from Oct 2025:
- The power fee is based on the average of the five highest power peaks from different days, during high-load time.

If you’re on “power subscription 80A+” (uncommon for houses):

There are already explicit power charges (monthly power fee and sometimes peak-load fee), e.g. 2026: SEK 67.5/kW per month (N4) + time-of-use transfer fees.

➡️ EV meaning: In Vattenfall areas, the EV impact becomes real when the model is rolled out (autumn 2026). The model tested for some customers uses 5 peaks (averaged), which means you want to be consistent across the month—not just avoid one single “bad peak hour.”

E.ON Energidistribution — current price lists don’t show a power fee, but a new model is announced

Current private price lists (example North/South):

Price lists show fixed subscription fee (SEK/month) + energy transfer fee (öre/kWh), but no power fee in the table.

Announced introduction:

E.ON has communicated that a new tariff model where a power fee is included will be introduced 1 Sep 2026.

➡️ EV meaning: In E.ON areas, the EV “power cost” is mainly an upcoming change (announced for 2026-09-01). Always check your local price list/network area.

Quick comparison (what matters for EV charging)

Ellevio: 3 peaks (average) + night “counts half” → easy to optimize with night charging + load balancing.
Vattenfall (pilot/selected group): 5 peaks (average) during high-load time → requires steadier behavior throughout the month.
E.ON: power fee announced but not in today’s price-table → depends on when/how it’s implemented in your area.
