In late June 2026, a 'heat dome' pushed PJM Interconnection, the largest power grid in the US, to its limits.
On July 1st, this grid serving 67 million people recorded its second-highest electricity demand ever, at 161,910 MW.
The next day, operating reserve capacity plummeted from 10,996 MW to 5,091 MW, a dangerously thin cushion.
Consequently, on June 30th, Energy Secretary Chris Wright signed two emergency orders, effective at 11:59 PM that night.
The first order allowed designated power units to temporarily exceed environmental emission limits to generate at full capacity.
The second order, as a last resort, permitted the grid to mandate large-scale users over 50 megawatts (like data centers and bitcoin mining farms) to cut grid power within 15 minutes and use their own backup generators.
On July 2nd, wholesale electricity prices soared above $2,000/MWh, with the Western Hub day-ahead settlement price hitting $1,222.75/MWh, nearly triple the comparable peak price from the previous year.
From July 1st to July 3rd, PJM issued consecutive high-temperature warnings and maximum generation alerts, urging power plants to postpone maintenance and operate all units at full capacity.
Meanwhile, at a mining farm within PJM's territory, rows of ASIC miners were systematically powering down.
Think the miners were staring at black screens losing money? The reality is quite the opposite; they might have been earning profits higher than mining.

I. Shut Down and Get Paid
Within the power grid system, large-scale Bitcoin miners are never merely 'power hogs'; they are actually engaging in a type of 'hedging' business.
The grid has a 'demand response' mechanism.
Simply put, the grid signs agreements with large customers: I supply you with low-cost electricity normally, but during extreme weather when the grid is near collapse, you must follow my orders and shut down obediently. In return, I will give you substantial compensation.
PJM's ELRP (Emergency Load Response) and CP (Capacity Performance) programs are typical examples of such mechanisms.
Sites of mining companies like Bitfarms and Mawson within PJM all participate in local demand response programs.
Furthermore, in the neighboring ERCOT grid in Texas, leading miner Riot Platforms has successfully commercialized this business model.
In Q1 2026, they received a total of $21.0M in power curtailment credits, a surge of 171% year-over-year.
Of this $21.0M, $13.5M came from direct power usage reductions, and $7.5M from demand response participation.
CFO Jason Chung stated on the earnings call that these credits helped reduce their net power cost to $0.03 per kilowatt-hour, lowering the direct mining cost per Bitcoin to $44,629, a 26% decrease from the previous quarter.
After all, when electricity prices spike, it's more profitable to simply shut down the machines and 'sell' the power back to the grid for a price difference than to operate them at a loss for mining.
In essence, they have turned idle computing power into an 'insurance product' for the grid.
II. The Real Power Guzzler is AI
While miners found a lucrative path in shutting down, zooming out reveals that Bitcoin mining farms are but minor players in this battle for electricity.
What prompted the two emergency orders from the Department of Energy were primarily AI data centers.
PJM's capacity auction price skyrocketed over 10-fold, from $28.92/MW-day for the 2024/25 period to $329.17/MW-day for the 2026/27 period, hitting the price cap.
Why such a frenzied increase?
PJM itself predicts that regional electricity demand will surge by 32 GW by 2030, with 30 GW of that coming from data centers.
Northern Virginia, the world's largest data center hub, has its power company Dominion Energy scrambling to meet demand.
Back in February 2026, PJM warned of a potential 60 GW power supply shortfall over the next decade.
Electricity has become a resource fiercely contested by AI data centers. With supply struggling to meet demand, prices naturally rise.
In comparison, data from the US Energy Information Administration shows that Bitcoin mining accounts for only 0.6% to 2.3% of the nation's annual electricity consumption.
What's truly straining the grid is the exponentially exploding demand for AI computing power.
III. If You Can't Beat Them, Join Them: The Ultimate Transformation of Mining Giants
Weather forecasts predict continued extreme heat risks in the PJM region by mid-July.
While investors still closely watch wholesale electricity prices and miners' production cut announcements, the true top players have already started switching lanes.
Since AI is the biggest 'power guzzler' and also the biggest payer of the future, mining companies holding power quotas and site infrastructure naturally know which direction to head.
Taking Riot Platforms as an example again, they completed an identity shift in Q1 2026, transforming from a pure Bitcoin mining company into a 'large-scale data center operator'.
AMD expanded its contract for space at Riot's Rockdale facility from 25 megawatts to 50 megawatts in Q1.
For these leading players, traditional Bitcoin mining is becoming a cash-flow-providing foundational business.
The new valuation story for the future lies in hosting the power-hungry, high-performance AI computing power with their readily available power quotas and facilities.
The heat warnings are still sounding, and the power meters are still spinning.
In this life-and-death race for energy, capital always finds the most profitable niche one step ahead of the ordinary person.
