BTC: Fixed-Rating Electricity Surplus at $0.025/kWh - S17 normal 56 TH/s

BTC Electricity Surplus at $0.025/kWh - S17 normal 56 TH/s was $0.297 on 7 Nov 2026 (latest daily value).

What one Antminer S17 (56 TH/s, 2,520 W) would earn in a day after paying for its power at $0.025 per kWh, in US dollars.

Why use it. It shows whether this machine pays its power bill at that price, and how the margin moves with the hash price. How to read it. Above zero the revenue covers the power at that price; below zero it does not. Only power is deducted, not hardware, financing or pool fees.

Calculation. Exact definition: The daily USD reward scenario for one S17 normal device (56 TH/s, 2,520 W nominal) minus its 24-hour electricity cost at 0.025 USD/kWh. Positive values mean the scenario reward exceeds the electricity cost; negative values are retained and mean it falls short. This is not actual profit: only electricity is deducted, excluding hardware purchase, depreciation, financing, pool charges, downtime, taxes and facility or cooling overhead. Nominal ratings for 24 hours at 100% uptime are assumed and applied retrospectively, even before the model existed. Day D uses the D+1 00:00 UTC quote; open or unsealed days are unknown and missing inputs stay gaps. a - (2,520 / 1,000 × 24 × 0.025) = a - 1.512 USD, the cost of 60.48 kWh over 24 hours at a nominal 2.52 kW. a is the S17 normal daily USD reward scenario: the daily BTC-per-EH/s claimed-reward normalization × 56 / 1,000,000, valued at the positive admitted D+1 midnight BTC/USD quote (admitted retrospective daily closes before 2026-10-03; from then, admitted prospective quotes at or up to 15 minutes before the boundary).
