Which utilities have current rate data
The Utility Rate Database is the only comprehensive source of US electricity tariffs, but it is not uniformly maintained. NREL re-verifies roughly 150 utilities a year. Everything else keeps whatever it was last filed with — with no end date, so it still reads as active.

Why it matters
We measured every tariff against what its utility actually billed per kWh, using EIA-861 residential revenue over residential sales. The gap tracks the filing date almost perfectly:
| Filed | Tariffs | Median deviation from actual |
|---|---|---|
| 2025–2026 | 637 | +6.9% |
| 2023–2024 | 111 | +0.8% |
| 2015–2019 | 701 | −16.5% |
| before 2015 | 1,717 | −16.8% |
| undated | 123 | −20.4% |
Recent filings land within a few percent. Decade-old ones run about 17% low — roughly what a decade of price increases would predict. Because being out of date and being cheap look identical in the arithmetic, any ranking that ignores the filing date puts stale data on top. We therefore rank and publish only tariffs filed since 2020, and label every figure with its filing year.
Suspected upstream errors
URDB is crowd-maintained and contains transcription errors. We never silently rewrite an upstream value — a published figure has to be traceable to its source — so anomalies are flagged instead, excluded from rankings, and reported back to OpenEI. Current findings:
| Utility | Tariff | Issue |
|---|---|---|
| Georgia Power Co | SCHEDULE TOU-REO-18 TIME OF USE RESIDENTIAL ENERGY ONLY | fixed charge units disagree with this utility's other rates (peers use $/day) |
| San Diego Gas & Electric Co | TOU-DR-1 Coastal Baseline Region | fixed charge units disagree with this utility's other rates (peers use $/day) |
Utilities with a tariff filed since 2020
183 of 2,589. These are the utilities whose published rates we consider current enough to price against.
