You can use the guides above to help you understand your price to compare. However, because supply charges for shoppers vary by supplier, they are not represented in these guides.

The guides are offered in two formats: Microsoft Excel (XLS) and Adobe PDF. To use the Excel guide, simply input the four data points to the appropriate fields and the calculations will be done for you in the spreadsheet. If you do not have Microsoft Excel, the PDF shows you how to perform the calculations. Sample data is included.

Businesses that are on residential rates 111, 141 (summer) and 141 (winter) should use the Residential Bill Calculation Spreadsheet.
