OpenEI Utility Rate Database (URDB)
The actual filed tariff (tiered pricing, fixed charges, effective dates) of the utility serving a given postal code -- the input that turns a spec sheet into a real annual cost.

Worth knowing
- `is_default=true` can return an expired tariff; this project rejects any rate whose `enddate` has passed.
- Cost coverage (the share of postal codes with a verified, not state-average, tariff) is a separate denominator from model coverage and is never quoted in the same sentence.
