Frequently asked questions

Is Duke Energy's rate the same for everyone in its service area?

No — most utilities including Duke Energy offer multiple rate plans (tiered, time-of-use, flat) and rates can vary by usage level or time of day, so this is an approximate average, not a guaranteed figure for every account.

How often does Duke Energy change its rates?

Utility rates typically adjust periodically based on regulatory filings, fuel costs, and infrastructure investment — checking a recent bill is always more accurate than relying on a fixed published number.
