Read this first. This page is arithmetic on the utility's own published rates. It is not an audit, a quote, a bill or advice, and we are not your utility. Your real bill can include charges we leave out (listed on each page), rates change, and the utility's bill and rate ordinance always prevail. Check your own bill or ask your utility before you decide anything. Changing nothing is a valid result.
