How to actually read an electric bill (supply vs. delivery)

Two numbers control most of what you pay for power, and only one of them is usually negotiable. Knowing which is which changes the conversation.

An electric bill in a deregulated state is really two bills stapled together. Understanding the seam between them is the difference between a productive phone call and a wasted afternoon.

Delivery: the wires

Delivery covers the poles, wires, meters and maintenance that physically move electricity to your home. Your utility owns that infrastructure, the rate is set through a public regulatory process, and it is effectively not negotiable by an individual customer. What you can influence is the volume, and occasionally the rate structure — time-of-use plans, for example, price the same kilowatt differently by hour.

Supply: the electricity itself

Supply is the commodity. In roughly a third of states you can choose who sells it to you, which means the supply portion is genuinely competitive and genuinely worth reviewing. This is also where variable-rate contracts live — the ones that look excellent for three months and then track a market index into territory nobody budgeted for.

The three lines worth checking every month

  • Rate per kWh on the supply line — compare it to the utility default rate, which is public.
  • Whether your contract is fixed or variable, and when a fixed term expires.
  • Any line item that is not supply, delivery, or tax. Those are where discontinued services quietly persist.

Budget billing is worth a separate mention: it smooths your payments across the year but does not reduce what you owe. It is a cash-flow tool, not a savings tool, and it is often mistaken for one.
