Why a Pepco bill moved

The price change was the larger piece

From 2024 to 2025 the average full service bill at Pepco moved +13.9%, from $141.26 to $160.86. Holding the 2024 price fixed, the usage change of +1.0% is worth $1.42 a month. The price change of +12.8%, from 19.04¢ to 21.47¢, is worth $18.20 on 2025 usage.

Above the Maryland average

21.47¢ per kWh is above Maryland's 2025 residential average of 19.53¢. July 2026 in the state was 21.41¢, versus 18.83¢ a year earlier (+13.7%). The utility figure is a full year of average revenue. The state figure is one later month. A household that uses more than 749 kWh will not land on $160.86.

One full-service average

822,606 residential customers were on Pepco full service in 2025, at 21.47¢ per kWh. That average folds in the customer charge and whatever riders the utility booked as residential revenue. It is not the last block on a tiered tariff.

Season

The 2025 monthly average for this Pepco service was 749 kWh, and the Maryland residential average was 945 kWh. A single month can sit far from either figure. Compare kilowatt-hours with the same month last year before you treat the whole increase as a rate hike.

Time-of-use is already on the EIA schedule

EIA's 2025 dynamic-pricing file shows residential time-of-use activity at Pepco, with 395,081 residential customers enrolled in dynamic pricing. The expensive window is in the tariff, not in that enrollment count. Shifting a dishwasher or an EV charger only helps if you are actually on that schedule.

How to lower the bill

  1. Read the kilowatt-hours against this filing's average of 749 kWh a month. If your use is the thing that moved, the dollar total can rise on an unchanged rate.
  2. On the statement, separate the base energy charge from fuel or rider lines. A rider can move the total in a month when no new base-rate order exists.
  3. Match this month's weather to last year's same month. A mild comparison month makes an ordinary bill look like a hike.
  4. Start with LIHEAP for Maryland (https://www.acf.hhs.gov/ocs/map/liheap-map-state-and-territory-contact-listing). A Pepco discount beyond that program needs verification.
  5. 395,081 residential customers were already on a dynamic price in the 2025 EIA file. If you are one of them, the window on the tariff is the lever. If you are not, calling the utility to discuss the schedule is the first step, not shifting load you are not being charged extra for.
  6. If the read is marked estimated, the next actual read can true the account up or down. The tariff rule for that true-up needs verification.

In July 2026 the state residential price was 21.41¢, versus 18.83¢ a year earlier (+13.7%). The utility number is a 2025 annual average. The state number is one later month. They answer different questions. From 2024 to 2025, the average monthly bill for full service changed +13.9%. Average use changed +1.0% and average price changed +12.8%. Holding the 2024 price fixed, the usage change accounts for $1.42 a month. The price change, applied to 2025 usage, accounts for $18.20.

What was Pepco's average residential rate?

Using 2025 EIA-861 revenue and sales, the full service average was 21.47¢ per kWh. Average use was 749 kWh a month and the average bill was $160.86. This folds in whatever customer charges and riders the utility reported. It is not the marginal rate on your tariff.

Did Pepco raise rates?

The full service average price changed +12.8% from 2024 to 2025, from 19.04¢ to 21.47¢. That is average revenue per kilowatt-hour, not a commission order. No 2025–2026 order for this utility was retrieved for this page. A separate rider can still move a single month.

What bill assistance can Pepco customers ask about?

LIHEAP is the federal program for home energy bills (https://www.acf.hhs.gov/ocs/programs/liheap). Pepco may also offer an income-qualified discount, budget billing, or a medical baseline. The current offer, income cutoff, and how to apply need verification on the utility site and with the state LIHEAP office and Maryland Public Service Commission.

Are data centers why this bill went up?

Large computing load is raising U.S. electricity demand, and regulators can later recover new generation and wires costs from customers. EIA has not published a dollar line that isolates data centers on this utility's residential bill. That pass-through needs verification.
