Solar Power Tariff 2026: The New Smart Meter Bonus (20% Cheaper Charging)
Summary (TL;DR)
From 2026, Austria introduces a new solar power tariff: Between April and October, grid fees are reduced by 20% from 10:00 AM to 4:00 PM. Reason: During this time, there's plenty of PV power in the grid. Requirement is a smart meter with activated 15-minute reading and consent to data usage. The tariff applies automatically for everyone who meets the conditions.
What is the Solar Power Tariff?
The solar power tariff is a new regulation from 2026 that rewards consumers who draw electricity from the grid during sun-rich hours. Between 10:00 AM and 4:00 PM (April to October), grid fees are reduced by 20%.
Why Does This Tariff Exist?
The massive PV expansion means that often more electricity is produced at midday than can be consumed. The solar power tariff creates an incentive to consume electricity exactly then - and thus relieves the grid.
How the Savings Work
| Period | Time | Grid Fee Discount |
|---|---|---|
| April - October | 10:00 - 16:00 | -20% |
| April - October | Other times | Normal |
| November - March | All times | Normal |
Calculation Example
With average grid fees of 10 ct/kWh, you save 2 ct/kWh during sun hours. Those who shift 1,000 kWh per year to this time (e.g., EV charging, washing machine) save €20. Sounds little? In combination with a dynamic electricity tariff, where the spot market price is often also cheap at midday, it adds up.
Requirements for Solar Power Tariff
- Smart meter with activated 15-minute reading
- Consent to use of smart meter data
- Connection at lowest grid level (household)
- No separate registration needed - applies automatically
How to Activate the Tariff
- Check if your smart meter is set to 15-minute reading
- If not: Activate in your grid operator's portal
- Consent to data usage (also in portal)
- The tariff then applies automatically - no further action needed
Combination with Dynamic Electricity Tariff
The solar power tariff only affects grid fees. Combine it with a dynamic electricity tariff (aWATTar, Tibber, etc.), and you benefit doubly: Cheap spot market price PLUS reduced grid fees during midday hours.
Ideal Use Cases
- EV charging: When the car is home during the day
- Heat pump: Heat hot water during midday
- Washing machine/dryer: Set timer to 10 AM-4 PM
- Battery storage: Charge from grid even without PV
- Home office: Use power-intensive devices at midday
