5 Tips to Save Electricity in Austria 2026 (with Concrete Numbers)

The biggest lever: electricity in Austria is not the same price at all times. At night (0–6 AM), aWATTar HOURLY prices are typically 3–8 ct/kWh. In the evening peak (5–9 PM), prices are 15–25 ct/kWh.

Concrete savings:

Action: Set a timer on your wallbox and boiler for night hours (e.g. 1–5 AM).

aWATTar HOURLY is Austria's most popular dynamic tariff. Electricity price follows the EPEX Spot AT market — hourly. No fixed base rate — only a monthly service fee of approx. €6.

Why it's worth it:

• Average savings vs. fixed tariff: €200–600/year (depending on consumption and flexibility)
• Prerequisite: Smart Meter with 15-minute opt-in activated
• Contract: Monthly cancellation, no minimum term

Switch: Visit awattar.at, enter smart meter number — done in 10 minutes.

By end of 2026, 95% of Austrian households will have a smart meter. If you already have one but haven't activated the 15-minute data transmission (opt-in), you're missing out on:

• Dynamic tariff access
• Hourly consumption data (to identify power-hungry appliances)
• Automated control via ioBroker or similar

Activate: Log in to your grid operator's smart meter portal → Settings → 15-minute values → Enable

Time required: 5 minutes. Cost: Free.

If you have a PV system, battery storage is the next step. A 5 kWh battery raises self-consumption from 35% to 65–75%.

Concrete figures:

• 5 kWp PV system, 4,500 kWh/year production
• Without battery: 35% self-consumption = 1,575 kWh used (saves €354/year at 22.5 ct)
• With 5 kWh battery: 70% self-consumption = 3,150 kWh used (saves €709/year)
• Additional saving from battery: €355/year
• Battery cost: €4,000–6,000 → Payback: 11–17 years

Note: Battery storage is only worthwhile if you already have a PV system. Without PV, a battery has no solar surplus to store.

The easiest way to generate your own solar electricity — even for renters. Up to 800 W without planning permission in Austria since 2024.

Calculation:

• System cost: €450 (complete set, 800 W)
• Annual yield: 650 kWh (Vienna, south-facing)
• Self-consumption (70%): 455 kWh × 22.5 ct = €102/year
• Feed-in (30%): 195 kWh × 8 ct = €16/year
• Total saving: €118/year
• Payback: 3.8 years

With aWATTar HOURLY: Run appliances when solar output is high → self-consumption rises to 80–85% → saving increases to €130–140/year → Payback under 3.5 years.

The biggest gains come from combining a dynamic tariff with load shifting (tips 1–3). PV and battery storage (tips 4–5) add further savings but require upfront investment.
