How to lower your Pepco bill in DC: 7 ways that actually work in 2026
Pepco's rate is 23.9¢/kWh — 42% above the national average — and more increases are already approved. Here are 7 ways DC homeowners can meaningfully reduce their electricity bill, ranked by how much they actually save.
The Permanent Solution
All of these methods help, but only solar locks in your savings as Pepco rates climb. See your permanent savings.
A free solar PPA installs panels on your roof at zero cost. You pay $0 per month for the electricity your panels produce — and a 10kW system in DC offsets most of your Pepco bill. You'll still pay Pepco's ~$22 monthly customer charge for grid connection — you can't avoid that — but the electricity portion drops dramatically. With Pepco at 23.9¢/kWh and rising, a free PPA saves most DC homeowners $130–$230 per month from day one, with savings growing every year as rates climb. This is the only option that eliminates the rate increase problem permanently.
Pepco's bill has two main parts: the supply charge (the actual electricity) and the distribution charge (the wires and infrastructure). You can switch the supply portion to a competing supplier through DC's retail electricity market. Some suppliers offer fixed-rate contracts that can be cheaper than Pepco's Standard Offer Service rate, especially when wholesale prices are high. Visit the DC Public Service Commission's supplier comparison tool to see current offers. Note: this only affects the supply portion — distribution charges, which are rising fastest, stay the same.
Heating and cooling account for 40–50% of most DC home electricity bills. A smart thermostat like Nest or Ecobee can reduce HVAC energy use by 10–15% by learning your schedule and avoiding heating or cooling an empty house. At Pepco's rates, that's roughly $20–$40/month in savings. Pepco also offers a $75 rebate on qualifying smart thermostats through their energy efficiency program — check pepco.com/rebates for current offers.
DC's older housing stock — rowhouses, colonial homes, 1960s split-levels — often has significant air leakage around windows, doors, attic hatches, and electrical outlets. A professional energy audit (DC offers subsidized audits through the DC Sustainable Energy Utility) can identify exactly where you're losing conditioned air. Sealing and insulating can reduce heating and cooling costs by 15–25%. The DC SEUS program offers rebates of up to $3,000 for air sealing and insulation work.
If your home still has incandescent or CFL bulbs, switching to LEDs reduces lighting energy use by 75%. In a typical DC home this saves $15–$30/month. It's not a game-changer at Pepco's rates, but it's cheap and permanent. Pepco offers instant rebates on LED bulbs at participating retailers — look for the Pepco rebate sticker at Home Depot or check their website.
If you're on Pepco's time-of-use rate plan, electricity is cheaper during off-peak hours (typically evenings and weekends). Running your dishwasher, washing machine, and EV charger during off-peak hours can reduce your bill by $10–$25/month. To take advantage of this, you need to switch to Pepco's time-differentiated rate — call Pepco or log into your account to change your rate plan.
DC has several programs that directly reduce your Pepco bill if you qualify. The DC Residential Aid Discount (RAD) provides a 50% discount on electric bills for income-qualifying households. The DC Low Income Home Energy Assistance Program (LIHEAP) provides one-time bill payment assistance. The Utility Discount Program offers monthly discounts of $13–$37. See our full guide to Pepco bill assistance programs in DC for details on eligibility and how to apply.
Red flag: "You'll have zero electric bill." If a solar salesperson tells you there will be no Pepco bill at all — that's false. Every DC homeowner connected to the grid pays Pepco's mandatory customer charge of ~$22/month regardless of how much solar they have. Anyone promising a $0 bill is either misinformed or not being honest with you. A good solar company will tell you the truth: solar dramatically reduces your bill, but the customer charge always remains.
The honest truth about reducing your Pepco bill
Most of these options reduce your consumption — but they don't address the underlying problem, which is that Pepco's rate per kWh keeps rising regardless of how efficiently you use electricity. A 15% efficiency improvement saves you money today, but in five years when Pepco's rate is 30¢/kWh, that same efficiency improvement saves you proportionally more — but you're still paying Pepco more than you are today.
The only option that actually decouples you from Pepco rate increases is going solar. When your panels produce electricity, you're not buying from Pepco at all. Every year Pepco raises rates, the value of your solar system increases.
DC homeowners with a free solar PPA are effectively locked in at $0/kWh for the electricity their panels produce. As Pepco's rate climbs from 23.9¢ to 27¢ to 30¢ over the next decade, their savings grow automatically — without doing anything.
Frequently asked questions
How much can I save on my Pepco bill by going solar in DC?
A 10kW solar system in DC produces roughly 11,000 kWh per year — enough to offset most or all of a typical DC home's electricity use. At 23.9¢/kWh, that's about $2,600/year or $215/month in savings. With a free PPA, you pay $0 for the system and $0 per month, so the full savings go directly into your pocket.
Does Pepco offer any bill reduction programs?
Yes. Pepco offers the Residential Aid Discount (50% bill reduction for qualifying low-income customers), rebates on smart thermostats and LED bulbs, and budget billing that smooths out seasonal spikes. For income-qualified households, DC also has LIHEAP and the Utility Discount Program. See our full guide to Pepco assistance programs for eligibility details.
Can I really switch away from Pepco in DC?
You can switch your electricity supplier (the generation portion), but not the distribution company. Pepco owns the wires and infrastructure that deliver electricity to your home — that part of your bill is fixed regardless of which supplier you use. Distribution charges are where most of Pepco's recent rate increases are concentrated, so switching suppliers has limited impact on the fastest-rising part of your bill.
