Margaret Harrington

Role: Bills & Rates Editor

Margaret Harrington is the editorial byline for Utility Explained’s Bills & Rates desk. It identifies the desk responsible for guides that break down how electricity, gas, and water bills are put together — what each line item means, how rate structures (flat, tiered, time-of-use, demand charges) change what you pay, and where billing errors and estimated reads tend to hide.

For data-heavy billing guides, the desk uses primary sources such as U.S. EIA data, state public utility commission filings, and published provider tariffs. Refreshed guides show their source links and review date.

What Margaret Writes About

Margaret writes and reviews our electricity, gas, water, and billing-structure guides — the articles that explain every charge on your bill so you know what you’re paying for and whether it looks right.

Guides may use AI assistance during drafting. Data-heavy pages are being reviewed so material claims carry visible, dated primary-source links. See our editorial policy and methodology for details.

Read the full guide: The complete guide to understanding your utility bill is the desk’s flagship piece. Its rate and usage figures come from the U.S. Energy Information Administration’s Electric Power Monthly (eia.gov), cited with retrieval dates.
