If you’ve looked at an electricity forward curve lately, you’ve probably noticed something strange: prices for longer term contracts are higher than prices for shorter ones! That’s called contango, and it’s become one of the defining features of the U.S. power market.
The term comes from commodities trading, where it just means future prices are higher than spot prices. In oil markets, that usually signals tight supply or rising storage costs. In electricity, there’s no storage in the traditional sense, so contango tells a different story. It means the market expects the grid to get tighter over time. Buyers are willing to pay more today to lock in tomorrow’s power because they don’t trust that tomorrow’s prices will stay where they are.
For a commercial customer, this matters a lot. If you’re negotiating a new supply contract and the curve is in contango, waiting doesn’t help you. The market is telling you, in plain numbers, that later is more expensive than now.
So what’s driving it?
A few things are stacking on top of each other right now.
The biggest one is load growth from data centers. AI training and cloud computing demand has grown far faster than anyone forecasted even two years ago, and that demand is landing in specific regions hard, from Northern Virginia to parts of Texas. Utilities are having to plan for load growth they haven’t seen in decades.
At the same time, generation is coming offline faster than it’s being replaced. Coal plants continue retiring on schedule, and even some gas units are aging out, while new generation, especially anything that has to go through an interconnection queue, is taking years longer to get built than it used to.
Add to that the sheer cost of grid infrastructure. Transmission and distribution upgrades are expensive, and utilities are passing those costs through, which shows up in future price expectations even before a single new wire goes up.
And finally, electrification is quietly adding load everywhere. EVs, electric heating, and industrial process changes are all pulling more electrons through the same grid.
None of these are showing up all at once, and none of them are new stories on their own. What’s new is that they’re converging at the same time, and the forward curve is simply doing what it’s supposed to do: pricing in a future that looks tighter than the present.
If you’re a business buying power on a multi-year contract, this is exactly the kind of signal worth paying attention to before you lock in a rate!
