It has been a pretty long tradition now to have a different rate for electricity depending on time of day.
I think that part of that penalizes a lot of people though, since the most expensive period is when people come back home from work (the greater majority at least.) A time when people play on their computers, watch TV, run their laundry…
Here is the table showing the rates for the summer of 2019:
|12:00 AM to 12:00 PM|
Midnight to Noon
|12:00 PM to 5:00 PM|
Noon to Evening
|5:00 PM to 8:00 PM|
Evening to Late Night
|8:00 PM to 12:00 AM|
Late Night to Midnight
Stay cool and enjoy your summer!
