What affects your energy bill

Energy use

Winter: You may be using more lighting as daylight decreases. You also may be using space heaters, electric blankets or other devices to stay comfortable.
Summer: You may be using more appliances outdoors, such as a natural gas grill, electric tools for home improvement projects, pumps and cleaning equipment for pools and spas, power washers and other devices. Indoors, you may be operating fans, dehumidifiers and/or air conditioners more often.
Holidays: During holidays, you may be using more energy for cooking, cleaning, lighting and heating.


Winter: Cold snaps in some months can increase your bill by more than 10 percent as your heating increases.
Summer: Hot spells in some months can increase your bill by more than 10 percent as your cooling increases. Refrigerators and freezer also work harder if temperatures inside your home increase.

Natural gas costs

Your heating bill reflects the actual cost of natural gas we purchase on the open market. We have no mark up on such adjustments. Your bill shows a Purchased Gas Adjustment (PGA), which is the difference between what we anticipated paying for natural gas from our suppliers (base rate) and what we actually paid. When we buy gas for less than the base rate, you get a credit. When it’s more, you pay the difference.

Billing periods

Longer billing periods can increase bills. 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. An additional 5 days in a billing period can increase a bill 17 percent.
