READ MOREThe old legacy "on-peak" TOU window had previously been midday from noon to 6 pm. The new rates shift the "on-peak" window to much later in the evening, to 4 to 9 pm (or 5 to 8 pm in some cases). Ironically, midday energy usage used to be the most expensive ("on-peak"); now it''s become the cheapest ("off-peak" or "super-off
