This is the cost of the electricity supplied to you during the billing period and is the part of the bill that is subject to competition.

The Ontario Energy Board is responsible for regulating electricity prices for residential and small commercial consumers. More information about electricity pricing is available on the IESO or OEB website.


These are the costs of delivering electricity from generating stations across the province to ERTH Power then to your home or business. This includes the costs to build and maintain the transmission and distribution lines, towers and poles and operate provincial and local electricity systems.

A portion of these charges are fixed and do not change from month to month. The rest are variable and increase or decrease depending on the amount of electricity you use.

Regulatory Charges:

Regulatory charges are costs of administering the wholesale electricity system and maintain the reliability of the provincial grid.

Provincial Benefit:

This benefit indicates the difference between the regulated and contract prices for electricity that are paid to generators and the amount they would have received in the wholesale electricity market, called the IESO spot market. This will either be a credit or a charge depending on the prices for electricity in the IESO spot market.
