These times (4 to 9 on weekdays, and after 11pm) are different from the standard Time-of-Use periods on my Hydro-One Energy bills.
Do the times you quote apply to contracts for people with micro-grids?
[EDIT: You sent me an image of your bill, showing Ultra-Light Overnight (ULO) usage times. I'm not familiar with this program. My bill just shows Time-Of-Use (TOU) periods, which are different. I see you have to apply for this program with Hydro One. Thanks!]
