A former coal mine in West Virginia is getting solar panels today, courtesy of Google, which wants the output shaped hour by hour to match its own data centers’ appetite. Extraction site turned power plant for the machines that used to run on what came out of the ground there. A tidy loop, whether anyone planned it that way or not. There’s a zinc-based battery in the mix too, not lithium, which I’m noting mainly because it means someone is betting seriously on a chemistry nobody else picked.

But the detail I keep turning over is quieter. A technical brief on large-load tariffs, the contracts utilities write before they’ll agree to build power for a data center. Eighteen months ago these deals mostly had minimum contract lengths and collateral requirements. Now the “emerging” practices are upfront payment for impact studies, mandatory ramp schedules, and exit fees if the customer leaves early. That’s not boilerplate. That’s an industry that watched 3.8 gigawatts vanish from a grid in the time it takes to trip a breaker and decided a handshake wasn’t enough. Two hundred sixty-four tariffs catalogued so far, each one a little more specific about what happens if the load doesn’t show up, or shows up and then leaves.

Meanwhile NextEra picked up $1.9 billion in federal loans to restart Duane Arnold, the third old reactor this administration has financed back to life. Everyone’s hedging in a different direction at once: new solar shaped to speculative demand, old nuclear revived as a bet on demand nobody doubts, and a thickening stack of contract law in between, trying to make the middle ground behave itself.
