Pepco in Maryland: rates, bills and the 2026 increase
Pepco's 531,090 default-service customers in Maryland paid an average of 21.74¢ per kWh in 2025, for an average bill of $181.58 a month on 835 kWh.1 Over the last 12 months (Sep 2025–Aug 2026) the average was 23.35¢, and 25.76¢ in August 2026.2 Another 27,719 homes on its wires (5.0%) buy their supply elsewhere and pay Pepco delivery charges averaging 9.21¢ per kWh, plus their supplier's price.
EIA-861 2025 final (released October 7, 2026) and EIA's monthly utility survey through August 2026 (preliminary); next monthly update expected November 24, 2026. Averages are revenue divided by kWh, all charges included: not the rate printed in a tariff.
2 of 24 Maryland counties served (EIA-861 2025)
In Montgomery and Prince George's counties, Pepco's Standard Offer Service customers averaged 21.74¢ per kWh1 in 2025 and 23.35¢ per kWh across the last 12 months. In August 20263 the figure hit 25.76¢ per kWh, ahead of Delmarva Power (23.00¢ per kWh) and BGE (21.71¢ per kWh2), while Pepco's outage minutes stayed well under the Maryland average.
Pepco's price per kWh in Maryland, by period
Potomac Electric Power Company, an Exelon utility, has 558,809 residential customers on its Maryland wires, 22.7% of the state total; only BGE has more. Most of them, 531,0901 in 2025, also take Standard Offer Service, Pepco's default supply for anyone who has not signed with a supplier. Every price in this section refers to that group.
| Period | Pepco Maryland, Standard Offer Service homes | Source |
|---|---|---|
| 2025 (full year, final) | 21.74¢ per kWh1 | EIA-861 |
| Last 12 months (September 2025 to August 2026) | 23.35¢ per kWh | EIA-861M, 2026 months preliminary |
| August 20263 (one month, preliminary) | 25.76¢ per kWh2 | EIA-861M |
All three are averages of revenue per kWh: Pepco's residential billing for delivery, supply, the monthly customer charge and riders, spread over the kWh sold, without most taxes. None is a tariff rate. A household using fewer kWh than average sees a higher figure on its own bill, because the fixed charge is spread over less energy.
In 2025 Pepco's average was 2nd highest among the 7 Maryland utilities with at least 10,000 Standard Offer Service homes, a fraction behind Delmarva Power (21.81¢ per kWh). That put it 11.3% above the Maryland average, 22.3% above the national average for investor-owned utilities and 27th highest of 1771 large US utilities. Since then Pepco has moved ahead: 23.35¢ per kWh for September 2025 to August 2026, against 22.68¢ per kWh at Delmarva Power and 22.26¢ per kWh2 at BGE.

Rate increases: 2025, 2026 and the August decision
Pepco's annual average went from 20.08¢ per kWh in 2024 to 21.74¢ per kWh in 2025, a rise of 8.3%. Monthly use per home hardly moved (830 kWh4, then 835 kWh), so the bill grew almost in step: +9.0%, to $181.581. In August 2026 Pepco's average stood +9.3%2 above August 2025, while Maryland's residential average for that month was up 7.6%3.
Pepco's distribution charges in Maryland follow three recent orders of the Maryland Public Service Commission:
- June 2024: an increase smaller than Pepco asked for, with its proposed multi-year plan approved for the first rate year only.
- March 2026: part of Pepco's request to true up costs from the last year of its first multi-year plan, billed from April 1, 2026 to March 31, 2027.
- August 28, 2026: the decision on the base rate case filed in October 2025, granting less than half of the revenue Pepco sought, with rates in force the same day.
The August order took effect in the last days of the latest month EIA has published, so the monthly figures almost entirely reflect the earlier distribution rates. The supply side changes on its own schedule; according to the Commission, Standard Offer Service power is bought from wholesale suppliers through competitive bids it supervises, within the PJM1 regional market. The guide to rate cases walks through how each kind of change reaches a bill.
Same company, different bills across the DC line
Pepco also serves the District of Columbia, under the District's own regulator, which makes it a useful comparison. Per kWh, the two groups of Standard Offer Service homes paid similar averages in 2025, 21.74¢ per kWh in Maryland and 20.77¢ per kWh in DC, and similar ones for September 2025 to August 2026, 23.35¢ per kWh and 23.17¢ per kWh2. They got there differently: the DC average rose 25.3% from 2024 to 2025, the Maryland one 8.3%1.
Consumption sets the bills apart. A Pepco home in Maryland used 835 kWh a month in 2025, one in DC 593 kWh, and the bills followed: $181.58 against $123.11. Use also explains the order inside Maryland. BGE homes used 878 kWh and Delmarva Power homes 981 kWh, more than Pepco's, so Pepco's bill landed between BGE's $177.19 and Delmarva's $214.051 even with a higher price per kWh than BGE.

January, not August, is the heaviest month
Pepco's Maryland customers draw the most power in winter. Across September 2025 to August 2026, monthly use per home went from a low of 582 kWh (October 2025) to a high of 1,089 kWh (January 2026), with average bills of $142.97 and $241.74. In DC, Pepco's homes reached their high in July 2026 instead, at 772 kWh. The 12-month average bill of $196.052 therefore understates what a Maryland Pepco household pays in midwinter.

Where Pepco delivers in Maryland
EIA's service-territory file places Pepco in 2 Maryland counties, Montgomery County and Prince George's County5, and records other distribution utilities in each of them too. Which company serves a given street is settled by Pepco's own service map, not by the county or ZIP code, and Pepco's averages describe its customers, not any town.

Delivery charges for supplier customers
In EIA's 2025 survey, 27,719 Pepco homes in Maryland (5.0% of residential customers) had a licensed supplier, compared with 6.3% at BGE and 10.2% at Pepco in DC. The Maryland side has changed quickly since: the state Public Service Commission's enrollment reports show residential supplier participation across Maryland's investor-owned utilities and SMECO falling from 11.6% in December 2024 to 0.46% in December 2025 and 0.08% in September 20267. Their power still arrives over Pepco's lines, and Pepco charges them for that. Pepco's delivery-only revenue from these homes averaged 9.21¢ per kWh in 2025 (+2.7% on 8.97¢ per kWh4), about $73.31 a month for 796 kWh. Delmarva Power's delivery-only average was 9.06¢ per kWh and BGE's 7.40¢ per kWh1.
Supplier charges are billed in addition and do not appear in Pepco's EIA data. Across Maryland, homes with a supplier paid 13.27¢ per kWh1 on average for supply in 2025: a historical average over every contract, not a current offer. Delivery-only, supply-only and Standard Offer Service averages each describe a different group of customers and a different part of the bill, so they are listed separately and never summed. Switching is covered in retail choice in Maryland.
Peak-day credits and rooftop solar
Pepco reported 395,081 Maryland residential customers in a time-varying program in 2025, 70.7% of homes on its wires. EIA lists the program as critical peak rebates: households keep their normal rate and earn a credit when they reduce use during called peak events; there is no surcharge for using power then. Pepco's advanced meters (99.8%8 of residential meters) make the measurement possible. How such rebates differ from time-of-use pricing is explained in the time-of-use guide.
Pepco's Maryland territory has the densest rooftop solar of the state's large utilities in EIA's count: 39,736 net-metered residential systems totalling 329.4 megawatts, 71.1 per 1,000 customers. SMECO had 58.2 per 1,000 and BGE 42.78.
Fewer outage minutes than the state average
Including major events, a Pepco customer in Maryland was without power for 104 minutes on average in 2025, fewer than the Maryland average of 184 minutes; excluding them, 54 minutes, where the state figure was 80 minutes. The average customer had 0.74 interruptions over the year, measured under IEEE 1366. On the same all-events basis, Delmarva Power recorded 114 minutes, BGE 175 minutes and Potomac Edison 399 minutes9.

Businesses, and where to find bill help
Commercial accounts on Pepco's Maryland system averaged 16.49¢ per kWh in 2025, below the 21.74¢ per kWh of Standard Offer Service homes; Pepco's Maryland average over every class of customer was 20.58¢ per kWh1. For households struggling with bills, Maryland received $84.8 million10 in federal LIHEAP funds for fiscal 2026, and our guide to help with electric bills covers the assistance programs.
Pepco Maryland questions
What is Pepco's rate per kWh in Maryland?
Pepco's tariff has no single rate: it combines a customer charge, distribution charges and a Standard Offer Service supply charge. Spread over every kWh sold to residential Standard Offer Service customers, those charges came to 21.74¢ per kWh1 on average in 2025 and 23.35¢ per kWh2 for September 2025 to August 2026 (2026 months preliminary). Homes that buy supply from a licensed supplier are excluded from both figures.
What is the average Pepco bill in Maryland?
$181.58 a month in 2025 for 835 kWh1, against $166.634 in 2024. EIA's monthly sample puts the figure for September 2025 to August 2026 at $196.05; the costliest month, July 2026, averaged $273.642.
Is Pepco raising rates in 2026?
Yes. On August 28, 2026 the Maryland Public Service Commission set new Pepco distribution rates, effective that day, allowing less than half of the increase Pepco sought in its October 2025 filing. A separate reconciliation charge from Pepco's earlier multi-year plan applies from April 2026 to March 2027. EIA's figures stop before the new distribution rates; they show 25.76¢ per kWh for August 20263, +9.3%2 on August 2025 (preliminary).
Is Pepco cheaper in Maryland or in DC?
Per kWh, the 2025 averages were close: 21.74¢ per kWh in Maryland, 20.77¢ per kWh in the District. Monthly bills were far apart because Maryland homes used 835 kWh and DC homes 593 kWh: $181.58 against $123.111. Each jurisdiction has its own commission and tariff.
