What Is My Electricity Worth? – Feed-In Tariff, Bitcoin Mining & the New ElWG 2025
With the new Electricity Industry Act (ElWG), the Austrian federal government is setting the course for the country’s electricity future anew. For many PV owners, central questions now arise: What will I receive in the future for fed-in electricity? Is a feed-in system still worthwhile at all? And what alternatives are there?
What changes with the new law?
According to the ORF report from July 11, 2025 (ORF.at), the ElWG brings a number of innovations — many of which specifically affect those people who generate their own electricity:
Die wichtigsten Punkte im Überblick:
|
Innovation according to ORF |
Impact |
|
Peak capping on feed-in |
During high PV production (e.g., midday), your feed-in will be capped — either technically or financially. |
|
Grid fees also for feed-in |
In the future, you will have to pay grid fees even when feeding electricity into the grid — not just when consuming. |
|
Flexible grid tariffs |
Compensation varies depending on time of day, grid load, and market conditions. |
|
Subsidies for electricity from renewable sources |
State support will become more targeted but also more selective. |
|
Social tariff for low-income households |
Electricity consumption up to 2,900 kWh/year will be heavily discounted (approx. 6 cents/kWh). |
What does the new law mean for PV system owners?
Less feed-in — more self-consumption required
- Peak capping: During times of high solar output, not all PV electricity may be fed into the grid.
- You must consume or store the electricity yourself — otherwise it is lost.
New costs due to grid fees on feed-in
- In the future, you will have to pay grid fees when feeding electricity into the grid — similar to when you consume electricity.
→ Feeding electricity into the grid is only economically viable to a limited extent.
More planning and technology necessary
- Without intelligent control systems, electricity may be lost if not used in time.
PV systems need to be better coupled with consumption or storage devices.
→ Smart home solutions, heat pumps, or heating systems with additional benefits will become more relevant.
Innovative uses become more attractive — e.g., Bitcoin mining
- If feeding electricity into the grid is no longer economically feasible, alternative self-consumption options become worthwhile.
Example: With 21energy, you can convert your electricity into heat + Bitcoin — without grid feed-in, thus independent from the grid and free of fees.

Tip: Calculate your self-consumption now!
Use the free PV calculator to see how much self-consumption you can achieve under your conditions — and what benefits Bitcoin heating can bring you.
How can you best use your PV electricity?
The key lies in self-consumption: Use as much of your self-generated electricity as possible directly in your household — for example, for appliances, hot water, or heating. It’s especially efficient to run energy-intensive devices during the day when the sun is shining. Even smarter: rely on technologies like the electric heating systems from 21energy, which not only convert your PV electricity into heat but also enable you to earn passive income through Bitcoin mining. This way, you get the maximum out of your solar system — both ecologically and economically.
Conclusion: Self-consumption is the future
The new law makes it clear: PV is still worthwhile — but in a different way. Instead of simply feeding electricity into the grid, smart ways of using it in your own household are needed.
