The cooperative has two different residential rates, summer (for bills mailed June through October) and winter (for bills mailed November through May). You pay a kWh charge based on the season and a facility charge that is the same each month. Additionally, you may see a wholesale power cost adjustment, which reflects energy costs caused by the fluctuation in price for the fuels that generate electricity.

If you track usage, be sure to note the number of "billing days" in the cycle. That can change from month to month.

Remember, too, that extremes in hot weather and cold weather are likely to be reflected in your bill. Moving your thermostat just a few degrees can significantly change your bill.

You can view your power bill and usage for the past 12 months on your PowerPay 24 site.
