Understanding your Bill

The bill issued by ENWIN covers charges from three utilities: electricity from ENWIN and various provincial bodies, water from Windsor Utilities Commission, and waste water from the City of Windsor.

Knowing how to read your bill is a good way to monitor your exact electricity and water usage, and understand your monthly bill and the services it covers.

Glossary of Terms

This section, located on the back of your utilities bill, offers further information to help you understand your electricity and water charges.

Electricity Portion of Your Bill

ELECTRICITY - This is the cost of the electricity supplied to you during this billing period and is the part of the bill that is subject to competition. ENWIN collects this money on behalf of the generators.

DELIVERY - These are the costs of delivering electricity from generating stations across the province to ENWIN and then to your home or business.

Part of this money is forwarded across the province, to cover the cost of building and maintaining the transmission and distribution lines, towers and poles and operate provincial and local electricity systems. Part of this money stays with ENWIN, to cover the costs associated with building and maintaining the local distribution system (in Windsor).

A portion of the delivery charges is fixed and does not change from month to month. The rest is variable and increases or decreases, depending on the amount of electricity you use.

LOSS % (LINE LOSS ADJUSTMENT) - The delivery charge also includes costs related to electricity lost during the distribution process.

Equipment, such as wires and transformers, consumes power before it gets to your home or business. It is normal for a small amount of power to be lost as it travels over the utility's power lines to your home or business.

In calculating your electricity costs for the billing period, ENWIN multiplies your electricity charges by an adjustment factor, approved by the Ontario Energy Board, that accounts for electricity lost on the line. The charges for these losses are included on the DELIVERY line of your bill.

REGULATORY CHARGES - Regulatory charges are the costs of administering the wholesale electricity system and maintaining the reliability of the provincial grid. ENWIN passes these charges on to the regulator.

GLOBAL ADJUSTMENT - Electricity generators in Ontario receive a combination of payments from the operation of the wholesale market, payments set by regulation and payments under contracts. Your portion of the net adjustments arising from these and other authorized payments is included on your bill as the Global Adjustment.

Water Portion of Your Bill

This portion of your utilities bill covers the charges related to water production and distribution. ENWIN collects this money on behalf of Windsor Utilities Commission, at rates set by the Commission, for potable water, and on behalf of the City of Windsor, at rates set by the City, for waste water charges.

FIXED CHARGE - Fixed monthly charge based upon the size of meter connected to your address.

WATER USAGE - Amount of water in cubic metres (CM) consumed at the address during the billing period.

WATER MAIN REPLACEMENT LEVY - 45% of the sum of the Meter Fixed Charge plus Water Usage.

WASTE WATER FIXED COMPONENT - Fixed monthly charge based upon the size of the meter connected to your address.

WASTE WATER FIXED COMPONENT - Calculated at a rate per number of cubic metres (CM) consumed at the address during the billing period.
