What are dynamic electricity tariffs in Austria 2026?
Dynamic electricity tariffs are contracts where the energy component follows the hourly EPEX Spot day-ahead price for the Austrian bidding zone. They require a smart meter with activated 15-minute load profile recording. Since the new Elektrizitätswirtschaftsgesetz (ElWG / ElWOG amendment), suppliers with more than 200,000 customers must offer at least one dynamic tariff (source: E-Control, "Dynamic electricity tariffs", 2025).
Key takeaways
- Dynamic tariffs follow EPEX Spot prices — usually cheap at night and midday, expensive in the evening peak
- Real savings exist, but only with shiftable loads (EV, heat pump, battery storage)
- Requirement: a smart meter with the 15-minute "opt-in" measurement active (E-Control)
- Without flexibility, a dynamic tariff can be more expensive than a fixed-price tariff
- Switching is usually possible within 14 days; cancellation periods are often monthly

How dynamic electricity tariffs work
Price components: exchange price + markup + grid fee + taxes
| Component | Description | Typical range |
|---|---|---|
| Spot price (EPEX Spot AT) | Hourly day-ahead price published by EPEX Spot SE | −2 to 30 ct/kWh |
| Provider markup | Fixed margin charged by the supplier | ~2 to 4 ct/kWh |
| Grid fee (Netzentgelt) | Regulated transport fee set per network area by E-Control | ~5 to 9 ct/kWh |
| Taxes & levies | VAT, electricity tax, green-power surcharge | ~3 to 5 ct/kWh |
| Final price | Varies by the hour, in line with EPEX | ~10 to 35 ct/kWh |
Price patterns through the day
The table below shows typical EPEX Spot AT price bands. Actual values depend on weather, wind/solar feed-in and total load. Real-time prices are available in provider apps such as aWATTar's price curve.
| Time of day | Typical spot price | Reason |
|---|---|---|
| 02:00 - 06:00 | 2-5 ct/kWh | Low load, frequent overnight wind feed-in |
| 11:00 - 15:00 | 3-8 ct/kWh | High PV generation in spring/summer |
| 07:00 - 09:00 | 10-15 ct/kWh | Morning consumption peak |
| 17:00 - 20:00 | 15-25 ct/kWh | Evening peak load, low PV output |
Requirement: smart meter with active 15-minute measurement
To run a dynamic tariff in Austria you need a working smart meter with the quarter-hourly load profile opt-in activated, as set out in § 81 ElWOG / § 144 ElWG. The first activation is free; further changes can be subject to a small fee (E-Control smart meter information).
Smart meter rollout status 2026
E-Control publishes a semi-annual rollout report. The Q4 2025 figure was around 96 % of all metering points nationwide (E-Control market reports). The table below shows distribution-network-operator (DNO) snapshots.
| Grid operator | Rollout status (approx.) | Contact |
|---|---|---|
| Wiener Netze (Vienna) | ~96 % | wienernetze.at |
| Netz Oberösterreich | ~92 % | netzooe.at |
| Netz Niederösterreich | ~88 % | netz-noe.at |
| Salzburg Netz | ~90 % | salzburgnetz.at |
| Energienetze Steiermark | ~85 % | e-netze.at |
Step-by-step: activating quarter-hourly measurement
- Confirm a smart meter is installed — digital display at your meter cabinet, or check your DNO's installation notice.
- Log into your grid operator's customer portal (for example smartmeter-portal.at for Wiener Netze) and switch on the load profile / 15-minute opt-in.
- Wait for confirmation: activation typically takes 2 to 4 weeks.
- Authorise data transfer to the new supplier inside the dynamic tariff contract.
Opt-in is mandatory
Under Austrian data-protection rules, smart meters only record daily totals by default. A dynamic tariff cannot be billed correctly until the 15-minute opt-in is active.

Who actually benefits from a dynamic tariff?
Strong fit
Worth considering if:
- Smart meter installed with the 15-minute opt-in active
- Consumption can be shifted (laundry, dishwasher, dryer)
- SG-Ready or smart-grid-compatible heat pump in use
- PV system with battery storage
- Electric vehicle charged mainly overnight or around midday
Weak fit
Probably not for you if:
- Most consumption happens between 17:00 and 21:00
- You have no large appliances that can be time-shifted
- You need a stable, predictable monthly bill
- You do not want to operate a smart meter or activate the opt-in
Illustrative savings scenarios
The following figures use a mid-range EPEX Spot AT reference of ~9 ct/kWh (Q1 2026 day-ahead, E-Control market data) plus a 3 ct/kWh provider markup. Grid fees, taxes and levies are included in both columns. These figures are illustrative — actual savings depend entirely on your individual load profile.
Scenario 1: household with overnight EV charging
| Position | Fixed-price tariff | Dynamic tariff |
|---|---|---|
| Household (4,000 kWh) | ~€1,000 / year | ~€900 / year |
| EV charging (3,000 kWh, night) | ~€750 / year | ~€420 / year |
| Total | ~€1,750 / year | ~€1,320 / year |
| Indicative saving | — | ~€430 / year (illustrative) |
Scenario 2: household with heat pump and PV
| Position | Fixed-price tariff | Dynamic tariff |
|---|---|---|
| Household (3,500 kWh) | ~€875 / year | ~€800 / year |
| Heat pump (5,000 kWh) | ~€1,250 / year | ~€880 / year |
| Total | ~€2,125 / year | ~€1,680 / year |
| Indicative saving | — | ~€445 / year (illustrative) |
Scenario 3: standard household with no flexibility
| Position | Fixed-price tariff | Dynamic tariff |
|---|---|---|
| Mostly evening consumption | ~€900 / year | ~€955 / year |
| Result | — | ~€55 / year extra cost |
Why "illustrative" matters
These tables are modelled scenarios. The Austrian Federal Chamber of Labour recommends a personal trial of 6 to 12 months with your actual 15-minute load profile before committing long-term.
Smart-home automation makes the difference
Useful devices
| Device | Role | Approx. price |
|---|---|---|
| Smart plug with timer | Turns appliances on during cheap hours | €20-40 |
| Wallbox (OCPP / smart-tariff ready) | Charges the EV automatically at the cheapest hour | €500-1,500 |
| SG-Ready heat pump | Boosts buffer-tank temperature when prices are low | often integrated |
| Home battery (4-15 kWh) | Charges overnight, discharges in the evening peak | €5,000-15,000 |
| Home Assistant / openHAB | Open-source orchestration with EPEX integration | ~€100 hardware + own time |
Provider apps
Most dynamic suppliers ship apps that:
- show day-ahead hourly prices (typically released around 14:00 CET for the next day)
- send push alerts for unusually low or high hours
- give an hour-level consumption analysis
- let the wallbox or heat pump trigger on price thresholds
Risks and contractual fine print
Price risk in market crises
Caution: extreme spikes can occur
- During the 2022 cold-snap / gas-shortage period, EPEX hourly prices repeatedly cleared above 50 ct/kWh
- Negative prices (sunny weekends) occur but are not always fully passed on — taxes and grid fees still apply
- E-Control recommends keeping a financial buffer for more expensive quarters
Contract details to check
- Quarter-hourly billing: thousands of line items appear on the annual statement — use the provider app to spot anomalies.
- Bonuses: new-customer cashback is often not paid on pure spot tariffs.
- Minimum term: typically 1 month for pure spot products; up to 12 months for hybrid offers.
- Right to switch: ElWG guarantees a switch in maximum three weeks (E-Control switching guide).

Switching checklist
Before you switch to a dynamic tariff
- Smart meter installed? If not, request a swap from your grid operator
- 15-minute opt-in active in the grid operator's customer portal?
- Have you reviewed your own load profile (share of consumption between 17:00 and 21:00)?
- Which appliances can actually be automated?
- Are the supplier's app, your wallbox and heat pump compatible?
- Trial period planned (at least 6 months)?
Bottom line: who should choose a dynamic tariff in 2026
Dynamic tariffs are a genuine savings tool when you can move large loads into cheap hours. Households with EVs, heat pumps or PV plus battery can realistically save several hundred euros per year depending on their load profile. For standard households with a classic evening-heavy profile, a floater or low fixed-price tariff typically remains the calmer choice.

Frequently asked questions
How much can a dynamic tariff really save me?
It depends on your 15-minute load profile and the current EPEX curve. Modelling by E-Control and the Austrian Energy Agency points to roughly 10 to 20 % savings for households with an EV or heat pump that can shift demand into cheap hours. Without flexible loads, the upside is much smaller.
What happens when EPEX prices go negative?
Negative EPEX Spot prices do occur, especially on sunny weekends in spring. You pay nothing for the energy component (or receive a credit), but taxes and grid fees still apply. Whether the provider passes the full negative price on is set out in the tariff sheet.
What is the difference between a floater and a dynamic tariff?
Floaters update the price monthly, usually tied to a monthly EPEX index. Dynamic tariffs change the price hourly or every 15 minutes in line with the spot market and need a smart meter with active 15-minute measurement.
How do I activate quarter-hourly measurement on my smart meter?
Log into your grid operator's portal (for example Wiener Netze or Netz NÖ), open the load-profile section and switch on the 15-minute opt-in. Activation is free and takes 2 to 4 weeks (E-Control smart meter information).
Can I switch back to a fixed-price tariff at any time?
Yes. Most dynamic tariffs have short notice periods (often one month). According to E-Control a switch takes a maximum of three weeks and is free of charge.
Which Austrian providers really run hourly dynamic tariffs?
Currently aWATTar (HOURLY), Tibber, Verbund (Spot), Energie AG OÖ (OptimaSpot) and OurPower operate hourly-billed spot tariffs. Several municipal utilities additionally offer monthly floaters — those are not the same as hourly dynamic tariffs.
