Electric and utility bills use confusing terminology that makes it nearly impossible to know if you're being overcharged. Between supply charges, delivery charges, demand fees, and seasonal rate tiers, most people have no idea what they're actually paying per kilowatt-hour — or whether their bill is reasonable. BillBreakdown reads your utility bill, explains every line item, and identifies ways to reduce your energy costs.
Common Charges Explained
Supply / Generation Charge
The cost of the actual electricity you used, measured in kilowatt-hours (kWh). This is the core charge — everything else is fees on top of it.
Delivery / Distribution Charge
The cost to deliver electricity through the grid to your home. This goes to your local utility company, even if you buy power from a different supplier.
Demand Charge
Often NegotiableBased on your peak usage during the billing period, not total usage. Common for commercial accounts. One hour of high usage can spike this charge for the entire month.
Fuel Adjustment / Cost Recovery
A variable surcharge that changes with fuel prices. When natural gas or coal prices rise, this fee goes up. It can swing your bill 10-20% month to month.
Renewable Energy Surcharge
A fee to fund state-mandated renewable energy programs. Typically $2-10/month for residential customers.
Late Payment Fee
Often NegotiablePenalty for paying after the due date, usually 1-3% of the outstanding balance. Call your utility to request a waiver — most will remove it once.
Red Flags to Watch For
Usage (kWh) that's significantly higher than the same month last year without explanation
Estimated readings instead of actual meter readings — these can be wildly inaccurate
Being on a tiered rate plan when a time-of-use plan would be cheaper for your usage pattern
Budget billing that's set too high — check if your payments exceed actual usage
Charges for services or programs you can opt out of
Abnormally high demand charges that suggest an equipment issue
How to Lower This Bill
Compare supply rates — in deregulated states, you can choose your electricity supplier. Shopping around can save 10-30% on the supply portion of your bill.
Switch to a time-of-use rate plan if available. Run heavy appliances (dishwasher, laundry, EV charging) during off-peak hours to pay less per kWh.
Request a meter accuracy test if your usage seems abnormally high. Utilities are required to test your meter for free if you suspect it's faulty.
Check for low-income assistance programs like LIHEAP (Low Income Home Energy Assistance Program) — income limits are higher than most people expect.
Look into your utility's energy audit program — many offer free home energy assessments that identify insulation gaps, air leaks, and inefficient appliances.
Frequently Asked Questions
Why is my electric bill so high this month?▼
Common causes: seasonal rate changes (summer/winter tiers), estimated vs. actual meter readings, a new appliance or space heater, rate increases, or an actual equipment issue. Upload your bill to BillBreakdown to compare your per-kWh cost against local averages.
What is a kilowatt-hour (kWh)?▼
A kWh is a unit of energy. It's equivalent to using 1,000 watts for one hour — like running ten 100-watt light bulbs for an hour. The average US home uses about 900 kWh per month. Your rate per kWh is the most important number on your bill.
What's the difference between supply and delivery charges?▼
Supply is the cost of generating the electricity. Delivery is the cost of transmitting it through the grid to your home. In deregulated states, you can shop for a cheaper supply rate, but the delivery charge is fixed by your local utility.
Can I negotiate my utility bill?▼
You can't negotiate rates with regulated utilities, but you can: switch suppliers in deregulated markets, switch rate plans, remove optional charges, apply for assistance programs, and request late fee waivers. In deregulated states, competitive suppliers often offer promotional rates.
