The First Cold Snap Sends the Heating Curve Climbing in the Temperate North

The reprieve lasted about a fortnight. The first genuine cold snap of the season pushed south across the temperate north this week, and the grid operators who spent early November enjoying their slack watched the heating curve begin its long climb back up. It is the same arithmetic that flattered them in October, running in reverse: every degree the outside air drops, the network is asked for more, and fusion's comfortable third of the load starts, once again, to look less like abundance and more like a ceiling seen from below. There is nothing alarming in it yet. A November cold snap is routine, the reserve margin is wide, and Aurora Fusion Works reports its baseload fleet answering the demand without strain. But the operators read curves for a living, and they know the shape of the one now bending upward. "We got about two weeks of easy," said a control-room lead in Oslo, watching the numbers tick. "Now we start earning it back, degree by degree, until March." The autumn light is still golden. The worry underneath it has simply changed seasons.
