Fusion's Third Trims Power Bills, Not Water Bills

NEW YORK — The reactor that came online near Phoenix on Friday pushed fusion past 31 percent of the reconnected grid, and by Monday wholesale power had eased about four percent on the Cerulean Exchange — real relief, and the wrong bill. The line that squeezes household budgets in water-stressed megacities is not the kilowatt but the liter. Desalination and treatment costs held firm this week even as generation cheapened, because pumping and purifying water is its own market, insulated from the grid's good news. "Cheaper electrons do not make cheaper water fast enough to matter this summer," said Iris Delacroix, a commodities analyst who tracks the resource indices. Castellan Capital, which underwrites both energy and water megaprojects, reported steady financing flows into desalination even as power margins thinned. For a family in a rationed ward, the arithmetic is blunt: the light got a little cheaper; the tap did not. The two markets have not yet learned to move together.
