Net Metering

What is Net Metering?

Net Metering is a program whereby eligible customers with renewable generation facilities can reduce their net energy costs by generating their own energy behind-the-meter. During periods of time when the generation output exceeds customer load, the surplus energy can be exported back onto the distribution system for a credit against future energy consumption. Excess generation credits are shown and tracked on your monthly hydro bill and can be carried forward for up to 12 months. ERTH Power cannot pay customers for any excess generation.

For details, see Ontario Regulation 541/05: NET METERING.

Who is eligible?

The net metering program is designed for any Ontario customer who generates electricity and meets the following conditions:

  • The electricity generated is primarily for the customer’s own use
  • The electricity generated is transmitted to the customer’s own consumption point without reliance of the ERTH Power distribution system
  • The electricity is solely generated from a renewable source or a combination thereof

Contact ERTH Power for location-specific eligibility and review Ontario Regulation 541/05: NET METERING for detailed eligibility requirements.

What type(s) of generation qualify?

  • Wind
  • Solar
  • Water
  • Agricultural Bio-Mass
  • Combination thereof

How is my bill calculated?

Customers participating in the Net Metering program will have the net energy charge on their hydro bill adjusted according to the Net Metering Regulation. Essentially, customers will receive a credit or an adjustment on their monthly bill for the energy exported onto the utility’s grid up to, but not exceeding the value of the energy consumed from the utility’s grid.

If Net Metering customers export more power than they consume during a billing period, their excess credit is carried over into their next billing period. Excess energy credits from successive billing periods can be carried-over up to a maximum of 12 months.

For GST purposes, the supply of energy to the customer and the exporting of energy on to the utility’s grid are considered to be separate supplies. As a result, the customer will be charged GST based on the gross supply of electricity rather than the net supply.
