A customer-generator is a Hydro-Québec customer who produces electricity using equipment they own and operate to meet part or all of their energy needs.

If you’re a customer-generator, Net Metering Option III may be of interest to you. It allows you to inject your surplus power into the Hydro-Québec grid in exchange for credits applied to reduce your bill. Inversely, if the power you generate is not enough to meet your needs, you can draw power from the Hydro-Québec grid and enjoy reliable, high-quality service.

Your electricity bill will show your consumption in kilowatthours, detailing how much electricity was supplied by Hydro-Québec and how much you injected into the grid. If you generate more than you use, the surplus will earn banked credits that will be deducted from your future bills.

Managing your surplus bank

Under Net Metering Option III for customer-generators connected to an off-grid system, except the Schefferville and Lac-Robertson systems, if you feed in more electricity than you draw out, the surplus is put into a bank in the form of credits.

The value of the power injected into the system is equal to the number of kilowatthours (kWh) injected multiplied by a price that varies depending on the type of generating station that supplies electricity to the customer-generator.

Prices for electricity injected based on the type of generating station that supplies the system:

  • Heavy diesel power plant: 17¢/kWh
  • Light diesel power plant: 33¢/kWh
  • Arctic diesel power plant: 48¢/kWh

A bill under a contract with the Net Metering Option III for customer-generators cannot be below the applicable system access charge.

These credits cannot be exchanged for money or transferred to another electrical service contract. They will expire after a certain period of time.

Your surplus bank will be initially reset to zero at the start of the consumption period beginning on or after March 31 following your initial sign-up. After that, it will be reset to zero every 24 months. In other words, you have two years to use your credits, apart from those accumulated during the first months.

You may make arrangements with Hydro‑Québec for a later reset date, as long as it falls within the 24 months following your sign-up. Your bank will then be reset to zero at the start of the consumption period beginning after the selected date, and every 24 months thereafter. Since the first reset is scheduled for March 31 after you sign up for this option, be sure to contact us before then.

Example

Consumption period 1

Baseline data

  • Kilowatthours supplied by Hydro‑Québec 500 kWh
  • Kilowatthours injected into Hydro‑Québec grid 300 kWh
  • Surplus bank balance – previous period $0.00

Bill calculation

Value of electricity injected (arctic diesel power plant) 48¢/kWh x 300 kWh = $144.00
Surplus bank $0.00 + $144.00 = $144.00
System access charge = $12.33*
Energy 9.90¢/kWh x 500 kWh = $49.50
Amount due for electrical service $12.33 + $49.50 = $61.83
Maximum amount to be withdrawn from surplus bank $61.83 – $12.33 = $49.50
Amount due after withdraw from surplus bank = $12.33
Surplus bank balance $144.00 – $49.50 = $94.50

*Per month, prorated to the number of days in the billing period.

Consumption period 2

Baseline data

  • Kilowatthours supplied by Hydro‑Québec 800 kWh
  • Kilowatthours injected into Hydro‑Québec grid 250 kWh
  • Surplus bank balance – previous period $94.50

Bill calculation

Value of electricity injected (arctic diesel power plant) 48¢/kWh x 250 kWh = $120.00
Surplus bank $94.50 + $120.00 = $214.50
System access charge = $12.33*
Energy 9.90¢/kWh x 800 kWh = $79.20
Amount due for electrical service $12.33 + $79.20 = $91.53
Maximum amount to be withdrawn from surplus bank $91.53 – $12.33 = $79.20
Amount due after withdraw from surplus bank = $12.33
Surplus bank balance $214.50 – $79.20 = $135.30

*Per month, prorated to the number of days in the billing period.

Who can sign up for Net Metering Option III?

Residential customers, farmers billed at Rate D, DM or DN and small-power business customers billed at Rate G (without billing demand) who are supplied by an off-grid system and who are able to generate electricity from a renewable energy source. The eligible renewable energy sources are:

  • wind power
  • photovoltaic power
  • hydroelectric power
  • geothermal power (for electricity generation only)
  • bioenergy (forest biomass or biogas)

The electricity must be generated at a facility that is located at the same delivery point as the Net Metering Option.

Customers are responsible for the costs of purchasing, installing, maintaining and inspecting the equipment.

Equipment compliance

Your generating equipment must be compliant with current regulations in Québec and with Hydro-Québec standards E.12-05 and E.12-07, in accordance with the Conditions of Service in effect.

The maximum generating capacity of the equipment must not exceed the lesser of the following:

  • the estimated capacity required to meet all or part of your energy needs, or
  • 20 kW for single-phase delivery or 50 kW for three-phase delivery
