Key Takeaways

  • Bitcoin miner Riot Platforms pocketed tens of millions of dollars from Texas grid operator ERCOT during the 2022 grid crisis by shutting down operations.
  • Riot secured long-term power forward contracts at cheap, fixed rates, then sold that energy back to ERCOT at astronomical spot prices when heat waves hit.
  • Grid operators rely on miners as flexible dumploads: large energy consumers that can turn off on a dime to prevent immediate grid collapse.
  • AI data centers cannot copy this trade because heavy chip depreciation forces them to run continuously as baseload consumers.

How Riot Turned Electricity Into Arbitrage

In the summer of 2022, Texas was baking under record heat waves. Air conditioners strained the grid, spot electricity prices exploded, and the Electric Reliability Council of Texas (ERCOT) faced imminent rolling blackouts. During that same window, Bitcoin miner Riot Platforms collected tens of millions of dollars directly from ERCOT. The public was furious. The common assumption was that crypto miners were straining public infrastructure and extracting taxpayer cash.

Patrick McKenzie explains that the reality was pure financial engineering. Riot had locked in fixed-price power forward contracts long before the heat arrived. As McKenzie noted, “What Riot had done was it had purchased a power forward from ERCOT. And what purchasing power forward means is we agree in advance to the price of power, and I want to be buying that power all the time.”

Under normal conditions, Riot consumed that cheap power to run application-specific integrated circuits (ASICs) and mine Bitcoin. But power contracts in Texas are tradeable commodities. When heat waves threatened catastrophic failure, ERCOT needed instantaneous supply. Because building new peaker plants takes years and ramping them takes hours, spot power prices shot through the roof.

Riot faced a simple math problem: sell hash rate to the blockchain, or sell raw electrons back to the market. McKenzie described the transaction: “Riot went back to ERCOT and said, 'Okay, this is something we both planned for. In the event that the grid is stressed, and the grid is stressed right now, you can buy power back from me at the spot price.' And so ERCOT paid Riot several tens of millions of dollars to buy power.”

To ERCOT, paying Riot was cheaper than a blackout. Riot was an emergency interruptible dumpload. As McKenzie observed, “They're buying power that would be more or less otherwise unused during most times... Okay, we have a dumpload, a large user of power that is capable of turning off basically on a dime if we need it to.”

Why AI Data Centers Cannot Pull Off This Play

Founders watching compute buildouts often ask whether artificial intelligence clusters will adopt the same revenue model. The short answer is no.

The economics of modern AI compute are dominated by hardware depreciation. If you buy thousands of high-end graphics processing units, those chips lose value every minute they sit idle. A modern AI cluster has a tight payback window before the next generation of silicon renders it obsolete. Running an AI data center requires continuous 24/7 baseload power to service massive capital expenditures.

Bitcoin mining rigs operate under different constraints. Their capital cost per megawatt is lower, their workloads are completely stateless, and their operational software can sever connections instantly without corrupting complex distributed model weights. When power prices cross the threshold where a kilowatt-hour is worth more on the open grid than the expected value of the mined coin, miners flip the breaker off.

By treating fixed energy commitments as a two-way option instead of a sunk overhead cost, Riot converted an operational expense into an emergency hedge. They were not just running server racks; they were running a synthetic virtual battery.

What to Do With This

Audit your fixed capacity contracts this week, whether for bulk cloud compute reservations, office leases, or logistics blocks. If your business experiences variable demand, re-negotiate your next renewal to include explicit subletting, pause, or secondary-market resale rights. When disaster hits an entire sector, holding the right to release reserved capacity back to desperate buyers turns an operational liability into high-margin revenue.
