Supply charge
The electricity itself. This usually follows kWh times the supply, generation, or retail energy rate.
Use this when an electric bill has delivery, customer charge, riders, taxes, and supply lines that need to be compared separately from the energy charge.

What to check on the bill
Delivery is a large share of this bill. Review fixed customer charges, riders, and local distribution fees before blaming kWh usage alone.
Supply vs delivery
A high delivery charge is not always a usage problem. Some lines follow kWh, while customer charges, riders, taxes, and minimums can stay on the bill after usage drops.

Distribution or transmission lines that multiply kWh by a delivery rate. These can fall when usage falls.
Customer, meter, minimum, rider, public program, or local fee lines that may stay even when kWh drops.
Divide the cleaned bill by kWh to see whether supply, delivery, or fixed fees are driving the total.

An electric delivery charge is the cost to move electricity through utility poles, wires, meters, and local distribution infrastructure. It is separate from the supply or energy charge on many bills.
The delivery charge is usually the utility-controlled part of the bill for poles, wires, meters, local distribution, riders, and customer service. It can include usage-based kWh delivery lines and fixed charges that stay even when usage drops.
Delivery can look high when it includes fixed customer charges, minimum charges, distribution rates, transmission charges, public program riders, taxes, or a longer billing period. Usage-based delivery may fall with kWh, but fixed delivery lines often remain.
Multiply kWh by the delivery rate, then add fixed customer charges, utility riders, public program fees, taxes, and other delivery-related line items.
The supply charge is the cost of the electricity itself, often tied to generation or a retail supplier. The delivery charge is the utility infrastructure side, such as wires, meters, distribution, transmission, riders, and customer charges.
Many delivery bills include fixed customer charges, minimum charges, riders, taxes, and fees that do not drop much when kWh usage falls.
