Bitcoin miners face a 2027 test on US power demand

Bitcoin miners in the US are entering a tougher phase as power demand rises and grid operators collect more evidence on how large loads behave under stress. For crypto investors, that matters because access to cheap, reliable electricity can shape mining costs, expansion plans, and site valuations.

The US Energy Information Administration expects electricity use to rise from 4,195 billion kilowatt-hours in 2025 to 4,399 billion in 2027. It links that growth to AI data centers, crypto operations, and wider electrification. In 2026, commercial power use is also set to pass residential demand for the first time, showing how fast large facilities are changing the grid.

That puts Bitcoin miners in direct competition with AI data centers, factories, and households for capacity. In Texas, ERCOT already uses voluntary curtailment programs with big loads, many of them miners, to cut demand when the system is strained. But a 2026 working paper found miners respond less consistently when Bitcoin hashprice rises, which weakens the case that they are reliably flexible.

The pressure is not limited to Texas. PJM recently saw Virginia wholesale power jump from about $40 per megawatt-hour to more than $600 during a heat wave. ERCOT has also flagged over 5,000 megawatts of large loads, including crypto mining sites, as at risk of disconnecting during some grid faults. By 2027, miners will need a clear record of curtailment and grid reliability to keep winning power access.
