Does Demand for Power Go Up on Hot Summer Holidays and Weekends?

Occasionally we’re asked if demand for power goes up over a typically hot summer holiday such as Independence Day or a weekend.

While more people might be at home cranking up their air conditioners over a sweltering holiday or weekend, typically demand actually goes down. This is because, while you might use your air conditioner more heavily over a weekend, many offices and businesses, which use a lot of electricity to keep their entire buildings cool, close over a weekend or holiday and don’t use the amount of electricity it does throughout the work week.
