Dominion Energy serves over 2.7 million customers across Virginia, and bill fluctuations are common due to seasonal factors, fuel cost adjustments, and usage patterns. Understanding what drives your bill can help you take control of your energy costs.
Seasonal Usage Patterns
Virginia's climate means significant seasonal variation:
- Summer (June-September): Air conditioning can account for 40-60% of your bill
- Winter (December-February): Electric heating or heat pump usage increases costs
- Spring/Fall: Typically lowest bills with minimal heating/cooling needs
Fuel Cost Adjustment
Dominion's fuel factor charge fluctuates based on the cost of fuel used to generate electricity. This can cause bills to vary even with consistent usage. The fuel factor is reviewed and adjusted periodically by the Virginia State Corporation Commission.
Rate Riders and Surcharges
Your bill includes various riders for:
- Grid modernization and infrastructure investments
