We use something called the: Break-Even Efficiency Ratio It tells you the electricity price (€/kWh) at which your miner breaks even — based on its efficiency in Joules per TH (J/TH). 2/11

Why J/TH? It’s how much energy your miner uses to produce 1TH. Lower = more efficient. 3/11

To compare mining vs. feed-in, we convert mining revenue into €/kWh. You need two things: 🔹 Miner efficiency (J/TH) 🔹 Current hashprice (€/TH/day) 4/11

Let’s use a common example: 🔧 S19 miner ⚡ 100 TH/s @ 2950W 📉 Efficiency = ~29.5 J/TH 5/11

Now the hashprice. You can calculate it from the block reward + difficulty, but let’s assume: 💰 €0.05 / TH / day 6/11

Use this formula: €/kWh = (1000 / efficiency) × (hashprice / 24) Let’s plug in 29.5 J/TH and €0.05: = (1000 / 29.5) × (0.05 / 24) 7/11

Result: 💡 €0.0706 / kWh That’s your break-even electricity price. 8/11

So if your feed-in tariff is: ⚡ < €0.0706/kWh → Mining is more profitable ☀️ > €0.0706/kWh → Better to sell to grid 9/11

This lets you make smarter decisions during curtailment. No guesswork — just plug in your efficiency and the current hashprice. 10/11

Know your break-even. ✅ Use old-gen ASICs wisely ✅ Optimize during curtailment ✅ Mine when it makes sense 11/11
