Electricity price 2026: What 37 cents per kilowatt-hour means for a device that never turns off
By Dominik Lederer, Founder Polarblocks · As of August 27, 2026, 08:06 UTC
Key Takeaways
The electricity price in 2026 is the average working price that German households pay per kilowatt-hour, and according to the BDEW electricity price analysis from August 21, 2026, it currently stands at 37.0 cents per kilowatt-hour. In the previous year, it was 39.3 cents.
The decrease almost entirely comes from grid fees. In 2026, they average 9.2 cents per kilowatt-hour, which is 1.7 cents less than the previous year. Taxes, levies, and surcharges remain unchanged at 12.6 cents.
For a device that draws around 17 watts and never turns off, 37.0 cents per kilowatt-hour results in about 55 euros in electricity costs per year, or approximately 4.59 euros per month. The Bitaxe Gamma 601 consumes around 148.92 kilowatt-hours per year.
The honest limit upfront: The Bitaxe Gamma 601 mathematically covers its own electricity costs only at around 10.8 cents per kilowatt-hour. This does not happen in a German household. Anyone who buys the device as a source of income is buying the wrong thing.
What does a kilowatt-hour really cost in Germany in 2026?
According to the BDEW electricity price analysis from August 21, 2026, German households have paid an average of 37.0 cents per kilowatt-hour in 2026 so far. The price is composed of 15.2 cents for procurement and sales, 9.2 cents for grid fees, and 12.6 cents for taxes, levies, and surcharges. In the previous year, the average was 39.3 cents.
These three figures tell the whole story of the year. Procurement and sales have slightly decreased. Taxes and surcharges have not moved by a single cent. The entire decrease of 2.3 cents comes from the block that a household can influence the least: grid fees.
For a model household with an annual consumption of 3,500 kilowatt-hours, 37.0 cents means approximately 1,295 euros per year. At 39.3 cents, it would have been 1,375.50 euros. The difference is 80.50 euros. This is real, but it's not a new car.
Why is the electricity price falling in 2026 and how long will it last?
The federal government will pay the four major transmission system operators a subsidy of 6.5 billion euros from the Climate and Transformation Fund in 2026. This dampens grid fees. The federal government enacted the law on December 12, 2025, and explicitly limited the subsidy to 2026.
Here it is worth taking a closer look at two figures that are often confused. The federal government estimates the theoretical relief for a household with 3,500 kilowatt-hours at about 100 euros per year. The BDEW measures a market decrease in grid fees of 1.7 cents per kilowatt-hour, which results in 59.50 euros for the same household.
Both figures come from reputable sources and do not describe the same thing. One is a preliminary political estimate of the isolated subsidy effect, the other is a measurement of what actually arrives in the average tariff after all other cost movements. Anyone who quotes one of the two figures without this addition is quoting inaccurately.
And the time limit is the real point. Amprion, 50Hertz Transmission, TenneT TSO and Transnet BW continue to build grids. Whether another billion euros will come from the federal budget in 2027 is open. For any calculation extending beyond December 31, 2026, 37.0 cents is therefore the optimistic assumption, not the cautious one.
What do 37 cents mean for a device that never turns off?
The Bitaxe Gamma 601 draws around 17 watts and runs around the clock. This results in 148.92 kilowatt-hours per year. At 37.0 cents per kilowatt-hour, operation costs around 55.10 euros per year or about 4.59 euros per month. At 35.0 cents, it is 52.12 euros.
Let's put this into perspective. 148.92 kilowatt-hours is 4.25 percent of the annual consumption of a 3,500 kilowatt-hour household. A solo miner on the shelf is therefore not a power guzzler, but a rounding item next to the refrigerator, dryer, and heat pump.
More interesting is what the celebrated grid fee relief does for this particular device. 1.7 cents per kilowatt-hour multiplied by 148.92 kilowatt-hours results in 2.53 euros per year. Two euros fifty-three. The difference between the 2025 and 2026 electricity price levels for the Bitaxe Gamma 601 is exactly 3.43 euros per year.
An Antminer S21 Pro with 3,510 watts comes to around 30,748 kilowatt-hours per year. At 37.0 cents, that's around 11,377 euros in electricity costs. There, the same relief amounts to around 523 euros. The 2026 electricity price is an issue for industrial facilities, not for living room devices.
| Working price per kilowatt-hour | Annual cost | Monthly cost |
|---|---|---|
| 25.0 Cents (favorable switching tariff) | 37.23 Euros | 3.10 Euros |
| 35.0 Cents (Polarblocks house bill) | 52.12 Euros | 4.34 Euros |
| 37.0 Cents (BDEW average 2026) | 55.10 Euros | 4.59 Euros |
| 39.3 Cents (BDEW average 2025) | 58.53 Euros | 4.88 Euros |
| 45.0 Cents (expensive basic supply) | 67.01 Euros | 5.58 Euros |
What electricity price would a Bitcoin solo miner need to be self-sustaining?
The expected value of the Bitaxe Gamma 601 on August 27, 2026, is approximately 16.09 euros per year, depending on the exchange rate. Divided by 148.92 kilowatt-hours, this results in approximately 10.8 cents per kilowatt-hour. Only below this price does the statistical expectation cover the electricity. A German household tariff is triple that.
The calculation behind it is openly verifiable. With a difficulty of 125,807,076,547,198 and 1.3 terahash per second, the annual chance of a solo block is about 1 in 13,180. A block yields 3.125 BTC plus transaction fees, which at an exchange rate of 67,861 euros per Bitcoin, is around 212,066 euros, depending on the exchange rate, as of August 27, 2026.
212,066 euros divided by 13,180 is 16.09 euros. Compared to 55.10 euros in electricity costs at 37.0 cents, this results in a payback ratio of about 29 percent. For the Antminer S21 Pro, it is about 2,897 euros in expected value versus about 11,377 euros in electricity, so about 25 percent. Both calculations are negative.
This is where most miner articles become dishonest. A solo miner is not a savings account with a plug. It's a lottery ticket drawn every ten minutes, and electricity is the price of that ticket. If you accept that, you're making a conscious decision. If you don't know, you've been poorly advised.
"The 1.7 cents grid fee relief brings a Bitaxe Gamma 601 exactly 2.53 euros per year. Anyone who is thinking about their living room device because of the 2026 electricity price is calculating in the wrong place. The relevant figure is not the electricity price, but whether 55 euros a year are worth the 52,560 attempts."

How does a Bitaxe Gamma 601 compare to lottery and an industrial miner?
Three ways to exchange a little money for a small chance of a lot of money. Lotto 6aus49 costs 124.80 euros in net annual stakes for one betting slip. The Bitaxe Gamma 601 costs a one-time fee of 129 euros plus around 55 euros in electricity. An Antminer S21 Pro requires its own room.
| Bitaxe Gamma 601 | LOTTO 6aus49 | Antminer S21 Pro | |
|---|---|---|---|
| Chances of winning per year | 52,560 chances per year, each for a full block of 3.125 BTC plus transaction fees, annual chance around 1 in 13,180 | 104 draws per year, annual chance of winning the jackpot around 1 in 1,344,598, thus about a hundred times worse | 52,560 chances per year, annual chance around 1 in 73, but only achievable with heavy current and a dedicated room |
| Running costs in the home office | Around 55.10 euros in electricity costs per year at 37.0 cents per kilowatt-hour, about 4.59 euros per month, at any standard socket | No electricity, but 124.80 euros in pure stakes per year for one betting slip plus processing fee | Around 11,377 euros in electricity per year at 3,510 watts and 37.0 cents per kilowatt-hour, plus connection and soundproofing |
| Drawer risk (boredom factor) | Low, the AxeOS dashboard provides new best values every day and continues to run visibly on the shelf | High, the ticket disappears into your jacket pocket and nothing visible happens between two draws | Very high, 76 decibels and 3,510 watts banish the device from any inhabited room |
| Learning effect & hands-on blockchain fascination | High, hashrate, best difficulty, and pool connection are visible live in the browser and explain Bitcoin using a real object | None, the draw remains a black box of balls and a TV show | Present, but in the server room behind hearing protection, not at the kitchen table with children |
What role does a private solar system play in the 2026 electricity price?
Anyone operating a balcony power plant often feeds surplus electricity into the grid for a few cents, while consumption costs 37.0 cents. It is precisely in this margin that a continuous runner becomes interesting. A device with a 17-watt base load consumes surplus that would otherwise flow away at unfavorable conditions.
The precise wording is important. The statement of around 10 euros in electricity costs per year, which appears in some miner texts, applies exclusively with one's own photovoltaic system and never unqualified. Without one's own system, around 55 euros per year at 37.0 cents is the reliable figure, and that belongs in every honest calculation.
The second catch: a balcony power plant in Germany hardly delivers anything in December. A device that is supposed to run around the clock then draws grid electricity at the full tariff. Those who calculate with solar should calculate with a mixed rate, not with the summer value.
How can you specifically reduce the electricity costs of a continuous runner?
Four steps that actually make a difference for a device drawing around 17 watts. They cost nothing but a little time and can be done in an hour. The order is deliberate: the first step brings the most, the last the least.
- Check the working price. The difference between 45.0 and 25.0 cents per kilowatt-hour for 148.92 kilowatt-hours amounts to 29.78 euros per year, more than any setting on the device.
- Recalculate consumption with a meter. An intermediate plug for under 20 euros shows the real power consumption, including power supply losses. Calculate with the measured value, not the data sheet.
- Honestly assess overclocking. More voltage brings more hashrate, but disproportionately more watts. Optimizing for efficiency instead of peak values significantly reduces the annual bill.
- Allocate solar surplus. If a balcony power plant is running, every self-generated kilowatt-hour shifts the bill by 37.0 cents. In winter, this effect largely disappears.

How much electricity does a Bitaxe Gamma 601 consume per year?
The Bitaxe Gamma 601 consumes approximately 148.92 kilowatt-hours per year at a continuous power output of around 17 watts. At 37.0 cents per kilowatt-hour, this amounts to approximately 55.10 Euros per year. The product data specifies a range of 15 to 19 watts depending on the settings.
Will electricity become more expensive again in 2027?
The federal subsidy for transmission grid costs is legally limited to 2026. Whether and to what extent it will be continued has not been decided by the federal government. A forecast for 2027 would be speculation and is therefore not included in this article.
Is a solo miner financially worthwhile at 37 cents per kilowatt-hour?
No. The expected value of the Bitaxe Gamma 601 on August 27, 2026, is approximately 16.09 Euros per year compared to approximately 55.10 Euros in electricity costs. The return rate is around 29 percent. Mathematically, the device would only pay for itself at approximately 10.8 cents per kilowatt-hour.
Where can I find my own electricity price?
The energy price in cents per kilowatt-hour is listed on the last annual statement and in every contract confirmation, separate from the monthly basic price. Only this value should be used in calculations for a continuously running device. The basic price is incurred regardless of the miner anyway.
