Break-even electricity price

The electricity price, in cents per kWh, at which each class of bitcoin miner stops covering its power.

12.3¢ on Sep 21, 2026, against 16.2¢ a year earlier.

The power price at which a machine’s daily revenue exactly equals its electricity bill: above the line it mines at a loss, below it the difference is margin. Each line is a class of machine by efficiency.

The dashed levels are our own hosting rates. The gap between a line and the rate you pay is the machine’s margin — which is why the most efficient machines, at the cheapest power, keep mining through every market.
