What a bill costs before a single kilowatt-hour

By DueRiva · Published · Updated · Figures from data retrieved

Before a single kilowatt-hour, most published plans bill a fixed amount every month. Across the 243 plans priced here it runs from $0.00 to $60.00 a month, with a median of $15.81 — and the median plan’s fixed charge is 15% of a 500 kWh bill against 4% of a 2,000 kWh one.

Why it changes the price of a kilowatt-hour

A fixed charge does not move with the meter. The same amount is spread over whatever a household uses, so it takes a larger share of a small bill than a large one — which is why, on the same plan, a light user’s effective rate is higher than a heavy user’s.

It is the mechanism behind the pattern in what published electricity plans cost, state by state: the median rate falls as use rises in 43 of the 44 states and DC there.

Plans any household in the state can take, priced at each level of use. The share is the median plan's fixed charge as a proportion of its whole bill, taxes excluded.

Where it weighs most

At 500 kWh a month the fixed charge is 45% of the median bill in Nebraska, and 4% in New Jersey. The same dollars are a rounding error on a large bill and a visible part of a small one.

One row per published record. What the household pays before any electricity, and what that is as a share of the whole bill at the lightest level of use.

A plan without a fixed charge is not automatically cheaper

2 of the 243 plans bill no fixed charge at all. Whether that makes one cheaper is a question about the whole bill, and it can only be asked within a utility: a municipal utility’s price is lower whatever it bills. One utility here publishes both kinds.

At Los Angeles Department of Water & Power, they come out dearer: the charge is gone and the price per kWh is not.

Median annual bill at 1,000 kWh a month, on plans any household can take. A minus sign means the plans without a fixed charge cost less.

What these figures assume

The fixed charge is the one the record publishes, billed every month of the year. Taxes are excluded, and consumption is spread evenly across the months, so a plan whose charge varies by season is shown at its average.

A plan can also carry a minimum bill, which is not a fixed charge: it only applies when the bill would otherwise fall below it. Where a record publishes one, the rate engine bills it separately. No plan in this data publishes a minimum without also publishing a fixed charge.

How this page was made

Every figure here is computed when the site is built, from the records named below, by the same code that fills the state, utility and cost-to-run pages this guide links to. When those records are refreshed, the figures change with them; the words around them do not, which is why no sentence here states a direction the data has not been checked for.

The methodology page sets out what the rate engine assumes and where its figures stop being reliable.
