What affects your bill

Weather

Winter: Cold snaps in some months can increase your bill by more than 10 percent as your heating increases.
Summer: Hot spells cause greater air conditioning use that can increase cooling costs by 10 percent or more.

Billing periods

Because of holidays, billing periods are longer in December. A typical billing period is between 29 and 31 days, but holidays may make your billing period up to 37 days long. A difference of 5 days on your bill can increase your bill by 17 percent.

Energy use

Holidays: During holidays, you might use more energy for cooking, cleaning, lighting and heating.
Winter: Because the sun sets earlier, you may use more lighting than you do in other seasons.
Summer: You may use more energy for cooking outdoors, cleaning and home improvement projects. You also may use more energy in the summer to keep you cool and comfortable indoors and outdoors if you have an air conditioner, dehumidifier or swimming pool.
