Bill Gates has said something the rest of the AI industry would rather he had kept to himself. Some of the megacomplexes going up across the United States right now will not pay off. The electricity locked in will turn out to be too expensive.
The compute will be undercut by cheaper builds overseas. The next chip generation will arrive before the last one has earned its keep. Gates said it on stage. And then he said the harder thing—no community is going to absorb a higher power bill so a hyperscaler can place a bet that may not even land.“We don’t have permission to drive up people’s electricity costs,” he said. The sentence reads more like a memo to the boardroom than a soundbite.
And it lands differently coming from the Microsoft co-founder whose own small-reactor venture, TerraPower, stands to be paid to feed exactly this buildout. Gates is not a sceptic of the buildout. He is positioned to profit from it. He is telling the companies whose growth would underwrite his own returns that the story they are selling the country does not survive contact with the electricity bill.
Some of these datacentres will lose the bet—and the towns hosting them will be left with the shell
Gates called the current spend a frenzy and made the trade-off plain.
Operators are committing to facilities whose electricity will turn out to be too expensive, or whose value will be captured by the next chip generation before the current one has paid for itself.For a town being asked to host nine gigawatts of demand and a campus the size of a small city, that rewrites the calculation. The question is no longer whether the datacentre brings jobs and tax revenue. It is what the town is left with when the racks go dark in seven years—the substation, the grid upgrade, the water draw, and a tax base built on a tenant that is not coming back.
A White House pledge is one thing; a power bill in the mailbox is another
In March, Amazon, Google, Meta, Microsoft, OpenAI, Oracle and xAI sat in a room at the White House and signed the Ratepayer Protection Pledge, committing to cover the cost of all new power generation their datacentres require.The pledge has not silenced the backlash. A Gallup poll the same month found 70 percent of Americans oppose a datacentre near their home—worse than nuclear ever polled at its peak. A Public First survey of 15 large economies pegged US support at just 26 percent, the lowest in the world.
The signatures, in other words, did not reach the people whose bills are at stake. The pledge bought the industry a press conference. It did not buy a single permit.
The siting model that built the post-war grid is finished, and Gates is the one saying so
Forty-eight projects worth $156 billion were blocked or stalled in 2025. Another twenty died in the first quarter of this year. Kevin O’Leary’s Utah complex was forced last week to halve its footprint from 40,000 acres to 20,000 after the state Senate president demanded a 75 percent cut.Satya Nadella, on stage at Build the same week, conceded Microsoft would now seek community “permission,” not just permits. Gates went further. The post-war American grid scaled because regulated utilities absorbed the cost of new generation and passed it through to ratepayers across decades. That arrangement, he said in everything but words, is dead.The hyperscalers are writing the cheques now. Any of that cost bleeding onto a homeowner’s bill is no longer a planning oversight or a tariff to be negotiated down the road. It is the line that decides whether the next gigawatt gets built—or whether the buildout stalls at the county hearing.
