Who this guide is forFor residential owners connected to Hydro‑Québec’s main grid.
Scope and limits: This guide summarizes current primary sources. It is not a connection approval, legal opinion or tariff guarantee. Confirm the current distributor requirements before ordering equipment.

Recommended sequence

  • Engage an electrical contractor who is a member of the CMEQ.
  • Have the self-generation equipment application filed before the final equipment purchase.
  • Wait for conditional acceptance, then complete the prescribed work and testing.
  • Never export electricity before Hydro‑Québec issues formal authorization.

Who can apply for a residential interconnection?

Hydro‑Québec states that a residential customer must own and operate both the self-generation equipment and the property where it will be installed. The project must also comply with municipal rules and other applicable standards.

Who submits the application to Hydro‑Québec?

The owner’s electrical contractor evaluates and plans the project, then files the self-generation equipment application. Connection work must be carried out by a contractor who is a member of the CMEQ.

Can panels be purchased before Hydro‑Québec responds?

Hydro‑Québec recommends waiting for conditional authorization before buying the equipment. Local hosting capacity, protection requirements or distribution work can change the project.

Which standard applies to a small inverter-based system?

Standard E.12‑01 generally governs distributed-generation interconnection. Simplified standard E.12‑07 applies to facilities of 100 kW or less using certified inverters on the low-voltage distribution system. The electrical contractor confirms the applicable standard and version.

Is a system of 100 kW or less automatically approved?

No. The 100 kW threshold describes the scope of simplified standard E.12‑07, not automatic approval. Hydro‑Québec assesses hosting capacity and may place an application on hold or require an integration study.

When may the system start exporting electricity?

After installation, the electrical contractor performs compliance tests and submits a signed verification report. Hydro‑Québec issues formal authorization once the file is compliant. The equipment must not be connected to the grid before that authorization.

Does interconnection approval automatically include net metering?

No. Safe connection and the tariff option are related but distinct. After reviewing the project, Hydro‑Québec proposes the appropriate net-metering option when the tariff and project conditions are met.
