The Grid Holds at Thirty Percent as the Heat Peaks

Through the hottest week of the summer, commercial fusion held its share of the reconnected grid at roughly thirty percent — steady, unspectacular, and exactly what the operators wanted. At the Phoenix load-balancing center, where cooling demand across the American Southwest spiked with the heat, grid engineer Teresa Idowu watched fusion baseload absorb the swing that solar could not carry after dark. "Thirty percent sounds modest until the night the wind drops and the panels go dark," Idowu said. "Then it is the difference between a hot night and a dark one." The steadiness matters because the margin is thin: demand rises with every degree, and the next increment of supply is still upcoming. Aurora Fusion Works has signaled that a new baseload reactor is due to synchronize in early August, a step its chief executive Emeka Okonkwo has framed as "capacity arriving just behind the need." Until then, Idowu said, the grid runs the way it has all summer — full, balanced, and with no room to spare.
