Last week’s surge in temperatures also meant a surge on the power grid, though not quite to record levels.

Between July 4 and July 6 — when temperatures soared into the triple digits each day and simmered in the 90s at night — the increase in usage was 50 percent greater than normal, according to initial estimates from Commonwealth Edison.

Last week was the first time since August 1947 that Chicago has seen three consecutive 100-degree days, but still, the power grid did not reach the record usage that the utility company saw last July, a ComEd spokeswoman said.
