What this decides
Every bill in the model, in every year of the projection.
Refreshed from the API by a script, not typed by hand. One source for every state, so a ranking measures the market rather than the source.

Take it
- electricity-prices.json
The file the engine actually reads, unaltered, with the documentation blocks it carries.
- electricity-prices.csv
The 16 records flattened for a spreadsheet: value, verified date, source, caveats, note.
Our compilation is free to reuse with a link back. The underlying data is not ours to license — follow the source on any row for the authoritative version and its own terms. The full position.
The rest of the data
- Solar yield
How much electricity a kilowatt of panels makes in a year, by place. The only pure physics on the site.
- Installed cost
What a system costs installed, on both published bases: competitive quotes, and what buyers actually paid.
- Export rules
What the utility pays for a kilowatt-hour you send out. Decides payback more than sunshine does.
- State incentives
What a buyer can actually claim from a state, read from the statute or programme that grants it.
- Federal policy
The federal credit as data, versioned by year, with the dated events that changed it.
- Modelling assumptions
Everything the model assumes rather than sources: panel wattage, degradation, loan terms, escalation.
