About the data
Weekly US fuel prices, monthly home electricity and gas prices by state and utility, and utility rate cases.
How it works
1. Monitor
Kadoa checks EIA, BLS and state agencies for new figures every week.
2. Extract
It reads government data files and state web pages and pulls out each price and rate case.
3. Clean
Missing values stay blank, and implausible ones are rejected.
4. Publish
New figures go live on the site and in the CSV downloads.

Limits
EIA publishes electricity and gas prices two to three months late, so the latest months are missing.
Rate cases cover only California, Colorado, New York and Oregon. Heating surveys cover four Northeast states, October to March.
Rate cases and surveys are read from web pages and can contain extraction errors. Check the linked source before relying on one.
Electricity prices and bills
The 12-month price is total revenue over total kWh sold, so high-use months count more. Monthly prices mostly show the weather.
The average bill is revenue over customers, EIA's own method. When EIA withholds a month's sales, we compute them from revenue and price.
Change since 2019
Compares the latest 12-month price with the 2019 average. Inflation is the change in the CPI-U all-items index over the same periods.
Utilities
Utility figures come from EIA-861M and cover utilities with 10,000 or more homes. In retail-choice states such as Texas, Massachusetts and Ohio, they cover only a fraction of homes.
Rate cases
Requested is the increase a utility filed for. Approved is the first year's increase, where the regulator states it. A figure is shown only where the commission's page prints it.
