If you've looked at your Pepco bill and wondered exactly what you're paying per kilowatt-hour — and why it keeps going up — this page breaks it down completely.

The 23.9¢/kWh figure is the all-in residential rate — it includes every charge on your bill divided by your total usage. On top of that, the fixed $7.39 monthly customer charge applies to every Pepco residential customer regardless of how much electricity they use. That charge doesn't go away even if you install solar.

What makes up your Pepco bill

Your total Pepco bill isn't just one rate — it's several charges stacked together:

Distribution charge Delivery through Pepco's local wires to your home
Generation/supply charge (SOS) Cost of electricity set through wholesale auctions
Transmission charge Moving electricity across the regional PJM grid
Customer charge Fixed $7.39/month just for being connected
Taxes and riders DC taxes and regulatory surcharges
Total all-in rate ~23.9¢/kWh

How much has Pepco raised rates since 2020?

A lot more than most people realize. Here's what DC residential customers have actually absorbed since 2020 — in both dollars and percentages:

Period $ Increase % Increase Driver
2020 +$8.21 ~8% Distribution rate plan approved
2021 +$3.84 ~4% Rate plan year 2
2022 +$3.41 ~3% Rate plan year 3
June 2023 +$12.18 ~11% New multiyear rate plan begins
June 2024 +$8.12 ~8% SOS supply increase
Jan–May 2025 +$7.54 ~5% Distribution rate increase
June 2025 +$20.81 +17.7% SOS wholesale auction spike — highest in a decade
January 2026 +$3.80 ~3% Rate plan continuation
Total 2020–2026 ~+$68 ~52–60% Six years of compounding increases

The average DC residential bill was around $90–100/month in 2020. By June 2025, the average had risen to nearly $138/month. That's not a gradual drift — that's a fundamental shift in what DC electricity costs.

The June 2025 SOS increase of 17.7% in a single month came from a PJM capacity auction that set the highest wholesale power prices in nearly a decade — driven by data center demand, plant retirements, and years of underinvestment in new generation. That auction result landed on every Pepco SOS customer's bill within weeks.

This past winter brought the sharpest bills many DC residents had ever seen. Dozens reported bills that doubled or tripled. A Ward 4 councilmember received a $899 bill. An at-large councilmember got $1,100. One-bedroom apartment residents reported $400 monthly bills. Cold weather was part of it — but the underlying rate structure made those spikes possible.

Why is it accelerating?

1. Grid infrastructure costs

Pepco's two approved Multiyear Rate Plans ($108M and $123M) are funding grid modernization across DC. Those costs are baked into your bill whether you benefit from the upgrades or not. Consumer advocates have criticized the process, arguing Pepco was allowed to charge customers upfront without adequate review of how prior plan funds were actually spent.

2. Data center demand

Northern Virginia houses 35% of the world's data centers. That industrial demand has added an estimated $8–10 billion in regional energy supply costs since 2024 alone — which flows through to PJM capacity charges and ultimately to every Pepco customer's bill.

3. Supply tightening

Power plant retirements across the region are outpacing new generation coming online. PJM paused review of most new energy projects for years starting in 2021 — including wind, solar, and storage — which delayed the new supply that could have eased prices. The most recent capacity auction set the highest prices in nearly a decade.

What a typical DC household pays

The average DC residential customer uses around 614 kWh per month. At 23.9¢/kWh plus the fixed customer charge, that works out to roughly $154–$160 per month. Higher-usage households — those with electric appliances, older insulation, or central AC — often see bills of $200–$300 or more. This past winter, some DC residents hit $400–$1,100.

Are Pepco rates going to keep rising?

All available evidence says yes. The structural drivers — grid modernization costs, data center demand growth, regional capacity tightening — are not temporary. Pepco itself has submitted plans projecting continued annual rate increases of approximately 6% per year.

What this means for solar

At 23.9¢/kWh, every kilowatt-hour your solar panels produce is worth nearly twice the national average in savings. A typical 10kW system in DC produces around 11,000 kWh per year — offsetting roughly $2,629 in annual electricity costs at today's rates. As Pepco rates rise, that number grows every year.

DC is one of the strongest solar markets in the country precisely because the electricity you're replacing is so expensive — and getting more expensive every year. Solar doesn't just save you money today. It locks in today's economics while the grid keeps getting more costly.

A free solar PPA in DC saves roughly $2,600/year at today's rates — and that number grows automatically every time Pepco raises rates. Over 25 years at 6% annual increases, the cumulative savings are substantial.

Common questions about Pepco rates

What is the Pepco rate per kWh in 2026?
Approximately 23.9¢/kWh for residential customers on the standard SOS rate — 42% above the national average of 16.8¢/kWh.
Why is my Pepco bill so high even when I don't use much electricity?
The fixed monthly customer charge (~$7.39) applies regardless of usage. DC's delivery and transmission charges are also among the highest in the region — a significant portion of every bill is infrastructure cost, not just the electricity you actually consumed.
How much has Pepco raised rates since 2020?
The average DC residential bill has increased by roughly $68/month since 2020 — a total increase of 52–60% over six years. The June 2025 SOS increase alone was 17.7% in a single billing cycle.
Can I choose a different electricity supplier to get a lower rate?
DC has a deregulated electricity market, meaning you can choose a third-party supplier for the generation portion of your bill. Delivery charges remain fixed with Pepco. Some customers find savings with alternative suppliers — but watch out for introductory rates that increase after the contract period ends.
How much would solar save me on my Pepco bill?
A typical 10kW DC solar system produces around 11,000 kWh per year, offsetting most or all of an average household's electricity usage. At current Pepco rates that's roughly $2,600/year in savings — and that number grows as rates rise.
What is the Pepco customer charge?
Approximately $7.39 per month — a fixed fee every residential customer pays just for being connected to the grid. This charge stays on your bill even with solar, which is why a $0 Pepco bill isn't realistic — but a dramatically lower bill is.
