Rate cases
None collected yet. This utility files with a state commission, but we have not collected that state's docket system. Which states are collected. We would rather show nothing than an empty table that reads as "no rate cases".
A rate case listed here is not evidence that any data center caused it. The two facts sit next to each other because both are public, and the research on cause is genuinely contested.
