Many people are surprised when they receive their first summer electricity bill after moving in. DC is known for its hot and humid summers, making it difficult to endure without air conditioning. Winter heating costs can also be higher than expected. Here's a detailed breakdown of residential utility costs in DC.

The electricity provider in DC is Pepco (Potomac Electric Power Company). It is a power company under Exelon Corporation that supplies electricity to DC and parts of Maryland. As of 2024, the residential electricity rate in DC is about 12-14 cents per kilowatt-hour (kWh). This is around the national average, but the high electricity consumption due to DC's summer heat and humidity results in higher actual bills.

For a one-bedroom apartment, summer electricity bills (June to August) typically range from $120 to $200 per month. If you run the air conditioning 24/7 or use an older, non-inverter model, the bill can exceed $200.

Winter heating varies depending on the type of residence in DC. If you have gas heating, Washington Gas is responsible for gas supply. Gas bills are charged per therm, and during the cold winter months, you can expect to pay between $80 and $150 for gas. If you use an electric heat pump, winter electricity bills can rise to between $150 and $250. In new apartments or condos, heating may be managed by the building's overall system, and utilities may be included in the rent, so it's advisable to check what's included before signing a lease.

There are practical ways to reduce energy costs in DC. The DC government and Pepco run rebate programs for energy efficiency improvements. You can receive partial refunds or low-interest loans when purchasing energy-efficient appliances. Information about related incentives can be found on the DC Sustainable Energy Utility (DCSEU) website. Low-income households can receive energy cost assistance through LIHEAP (Low Income Home Energy Assistance Program). For apartment residents, using draft stoppers, curtains, and window sealing can help reduce winter heating costs.

Water service is provided by DC Water. For a one-bedroom apartment, the typical water bill is around $30 to $50 per month. Internet service is provided by Comcast Xfinity throughout DC, with basic packages costing between $50 and $70 per month. Summarizing the total utility costs for living in DC, for a one-bedroom apartment, you should budget around $200 to $350 per month in the summer, including electricity, and $200 to $400 per month in the winter for electricity and heating combined. This cost should be considered alongside rent for an accurate calculation of actual living expenses.
