Number of Billing Days. Your billing days may vary. The more days you've used energy, the higher your bill will be. Your utility bill tells you how many days your bill covers. You may have incurred a charge for some service from Montana-Dakota which will increase your bill.
Many customers ask why their utility bill is different from their neighbor's.
The type of construction, size and location of a house have a lot to do with how much energy it uses. A large, well-insulated house protected from the wind may use less heating energy than a small, poorly insulated house exposed to cold winter gusts. Differences in Occupancy. A dwelling's utility costs are also affected by its number of occupants, their ages and living habits. Since preferences in room temperatures, laundering, bathing and cooking styles differ among households, differences should be expected in the amount of energy used by dwellings even in the same neighborhood.
