so currently 100% of the power is coming from grids and build your own meter is pipe dream currently?

You have hit the nail on the head. For all practical purposes today, virtually 100% of the power driving the AI boom is coming from the traditional, public utility grid. However, calling the "build your own" strategy a pipe dream isn't quite accurate. It is more of a heavily-funded pipeline with a massive latency problem.

Here is the exact reality of the situation today and why "escaping the grid" is proving so difficult.

The Reality of Today's Power

Right now, hyperscalers do not have fleets of their own private power plants running. When they say they are "powering with 100% renewable energy," what they actually mean is they are buying power from the local grid (which is a mix of coal, gas, nuclear, and renewables) and then buying "Renewable Energy Certificates" (RECs) from wind and solar farms elsewhere to offset their carbon footprint on paper.

The actual electrons flowing into the data centers are coming from the exact same utility grid that powers the surrounding cities.

The Amazon/Talen Reality Check (The Grid Strikes Back)

The one major exception—Amazon’s $650 million purchase of a data center campus directly hooked up to the Susquehanna nuclear plant—recently became a perfect example of why building "behind-the-meter" is so hard.

Amazon and Talen Energy tried to expand the amount of power they could pull directly from the nuclear plant without passing through the public grid. In late 2024, the Federal Energy Regulatory Commission (FERC) actually voted to block the expansion.

Why? Because even if you build right next to a power plant, you are still technically connected to the broader grid for backup and stability. Utilities and regulators argued that Amazon would be "freeloading"—pulling massive amounts of power and destabilizing the local system without paying the transmission and maintenance fees that normal grid customers pay.

This ruling sent shockwaves through the tech industry. It proved that even if you buy a nuclear plant, you cannot simply declare yourself immune from grid regulations.

Not a Pipe Dream, Just a 10-Year Wait

The massive plans for Microsoft to restart Three Mile Island or Google to build Small Modular Reactors (SMRs) are not pipe dreams. The contracts are signed, the capital is committed, and the engineering firms are hired.

But money cannot alter the laws of physics or the pace of federal bureaucracy.

• The SMRs: The technology for commercial Small Modular Reactors is still being proven. Google’s target of 2030 is highly ambitious.
• The Gas Plants: Building on-site natural gas requires environmental impact studies, securing gas pipeline rights-of-way, and passing emissions regulations.

The Bottom Line

Today, hyperscalers are entirely tethered to the public grid. The "bring your own power" era is real, but it is currently in the heavy-construction and permitting phase. You will not see a meaningful percentage of AI compute powered by private, off-grid hyperscaler power stations until at least 2028 to 2032. Until then, they are fighting for grid access just like heavy manufacturing and traditional industry.
