Which address to use

We read every message. We are a small operation and cannot promise a reply time, but corrections are prioritized.

Report a fee change

To help us check a report quickly, include:

We compare the report with the cited source and any newer document, then update the record or flag it “Confirm with utility”. See corrections for the full process.

What we cannot help with

We cannot give a utility or contractor quote, arrange a connection, or tell you what your property will be charged. Only the serving utility can do that. Our methodology explains how the planning figures are built. Please do not send sensitive personal information; see the privacy policy for how emails are handled.
