Dynamic Electricity Tariff for Business in Austria 2026: Up to 25% Savings for Companies
Summary (TL;DR)
TL;DR: Dynamic electricity tariffs for commercial users (EPEX Spot AT) enable 15–25% savings when controllable loads are available (refrigeration units, machinery, EV chargers, air conditioning). Requirement: Smart Meter (half-hour metering mandatory for >100,000 kWh/year). Important: commercial spot-price tariffs differ from household tariffs — separate tendering or negotiation is required.
Why Do Spot Prices Make Sense for Businesses?
Commercial electricity consumers typically have controllable loads: refrigeration compressors, CNC machines, EV chargers, HVAC systems. These can be shifted by 1–4 hours without affecting operations.
Potential savings:
- 15–25% of annual electricity costs
- Concrete example: Company with 500,000 kWh/year → €15,000–25,000 savings
What Smart Meter Do You Need?
For annual consumption >100,000 kWh, a half-hour smart meter is already mandatory in Austria. This enables:
- Hourly consumption readings
- Real-time EPEX Spot AT price visibility
- Automated load shifting (via building management system or ioBroker)
For <100,000 kWh/year: Contact your grid operator. Installation is free in most cases.
How Does a Commercial Dynamic Tariff Work?
Unlike household tariffs (aWATTar, Tibber), there is no ready-made commercial product. The process:
- 1Request quotes from energy suppliers (Verbund, Wien Energie, EVN, Energie AG)
- 2Negotiate EPEX Spot AT as basis (plus grid fees, taxes, supplier margin)
- 3Implement load management — shift controllable loads to cheap hours (0–6 AM, midday on sunny days)
- 4Monitor savings via smart meter portal
Typical margin: 0.5–1.5 ct/kWh above EPEX Spot AT
Which Loads Can Be Shifted?
| Load type | Shift potential | Saving potential |
|---|---|---|
| Refrigeration/cold storage | 2–4 h precooling | High |
| EV chargers (fleet) | Night charging | Very high |
| Air conditioning | 1–2 h pre-cooling | Medium |
| Machinery (non-time-critical) | Shift to off-peak | High |
| Water heating (boiler) | Night hours | Medium |
Conclusion
For commercial consumers with controllable loads and >100,000 kWh/year consumption, a dynamic EPEX-based tariff is worth exploring. The effort for the initial setup pays off within the first year at current electricity price volatility.
