Monitor brief: Week 41, Oct 5–Oct 11, 2026
Bitcoin fell 3.3% to $83,676; a typical modern miner could pay up to 8.3¢ per kWh for power ($83/MWhMWhMegawatt-hour, 1,000 kWh: the unit wholesale power is priced in. $76 per MWh is 7.6¢ per kWh, the unit on a household bill.), and wholesale power at ERCOTERCOTThe Electric Reliability Council of Texas: the operator of most of Texas's power grid and its wholesale electricity market, home to many US Bitcoin miners. Houston hub averaged 4.2¢ ($42/MWh).
In plain words: a typical modern miner could pay up to 8.3¢ per kWh for power that week and still cover it. Wholesale power at the ERCOT Houston hub averaged 4.2¢ per kWh, so running paid on 6 of 6 days (by daily average).

power vs breakeven
| Grid hub | Average power | Days running paid | Left after power, per PH/s a day |
|---|---|---|---|
| ERCOT Houston hub | 4.2¢/kWh ($42/MWh) | 6 of 6 | $19.54 |
| ERCOT North hub | 3.7¢/kWh ($37/MWh) | 6 of 6 | $21.86 |

No reported node averaged a day above the $83/MWh breakeven this week. Averages are of daily means of 5-minute real-time prices (LMPLMPLocational marginal price: the wholesale price of power at one point on the grid, set every few minutes by the costliest plant needed to meet demand there.); hubs with under 5 days of data are left out. Hub prices are not a tariff.
