Pepco DC apartment electric bills · July 2026 rate guide

At 300 kWh, the current effective-average components produce about $74 in summer and $75 in winter. At 500 kWh, they produce about $124 and $125. At the 614 kWh residential example used by the DC Public Service Commission, the same method produces about $152 and $153.

These figures apply to the standard DC residential schedule with Pepco Standard Offer Service. A third-party supplier, Residential Aid Discount eligibility, a master-metered building, submetering, unusual billing days, or a lease that includes electricity can change what a renter actually pays.

The calculation deliberately returns unknown if a required rate component is missing or outside its verified period. RentSift does not fill tariff gaps with a generic web estimate.

The DC Public Service Commission says Pepco's new Standard Offer Service generation rate took effect July 1, 2026 after a one-month deferral. Its published impact example says a residential SOS customer using 614 kWh per month would see a 7.0% increase, or $9.56, in the total monthly bill.

Pepco's filed comparison shows summer generation rising to an effective average of $0.14677 per kWh and winter generation to $0.15235 per kWh for residential non-master-metered customers outside the RAD programs. Distribution and transmission effective-average components remain separate in the filing.

That is why an older article or calculator using a June 2025 supply rate should not be treated as a July 2026 answer.

Pepco's current Schedule R lists a $18.09 monthly customer charge. The 2026 distribution energy charge is $0.01982 per kWh for the first 400 kWh, then $0.05659 in summer or $0.03952 in winter above 400 kWh.

For comparable planning scenarios, the calculator uses the filed effective-average distribution, transmission, and generation components. The effective distribution component already represents customer charges, riders, and adjustments across the billing forecast, so the fixed customer charge is disclosed but not added a second time.

This is a planning method, not a reconstruction of every bill line. Actual bills can include usage-block effects, taxes, riders, credits, regulatory adjustments, and a different supplier price.

Ask whether the apartment is individually metered, master metered, or submetered; whether electricity is billed directly by Pepco or through a third party; and whether an administrative fee is added.

Ask for the last 12 months of actual electric use for the unit or a comparable unit, not only a dollar average. Usage lets you apply a current rate while a dollar figure may reflect an older tariff.

Confirm whether heat, hot water, cooking, and air conditioning are electric, and which utilities are included in rent. A lower advertised rent can stop being cheaper once tenant-paid utilities and mandatory fees are added.
