The Post-Summer Grid Post-Mortem Begins: Which Regions Browned Out, Which Rode It Out

FRANKFURT — Now that the cooling peak is behind them, the grid operators of the temperate north have begun the least glamorous and most important work of their year: writing down, without flattery, exactly what happened. The season's ledger is being assembled here district by district, and it is a study in unevenness. Fusion carried its third-plus share across the whole hemisphere, and the interlinked backbone held — but "held" is a hemisphere-scale word that hides a thousand local truths. Some towns rode the worst afternoons without a flicker. Others browned out for an hour when a neighboring region's demand spiked and the interlink, doing exactly what it was told, drew their margin away to somewhere hotter. "The grid did not fail. The grid rationed, and rationing has an address," one operator said, tapping a map speckled with the summer's dim spots. The instinct after a survived season is to celebrate the average. The discipline is to read the outliers — the specific streets that flickered — and to fix them before the cold arrives and asks the same reconnected machine a harder question. The post-mortem is unglamorous. It is also the only reason next summer might be better.
