What to write about

• Corrections. If a figure, a date or a statement looks wrong, send the page URL, what you think is wrong and, if you have it, a link to the primary source (the operator, regulator or government page). See the corrections page for what happens next.
• Data sources. Questions about where a number comes from, how it is derived, or why a figure is paused. The methodology answers many of these.
• Privacy requests. Questions or requests about personal data. The privacy policy explains what is and is not collected.
• Everything else. Questions, suggestions and disagreements with our methods.

What to include

The page URL and the “as of” time shown next to the figure help most, because live figures change and operators revise their data. For a U.S. reference page, the state and the data month you were looking at let us check the exact row.

What we cannot help with

We cannot give trading, investment, financial or operational advice, and we cannot act for a grid operator, utility or supplier. Questions about a bill, a connection or a tariff are best sent to your supplier or the operator concerned. We do not take on paid placements.

E-mails you send are used only to reply to you and to deal with what you raise.
