Quebec has the lowest residential electricity rates in North America. Hydro-Québec’s Tarif D sits at roughly 6.97 to 10.76 cents per kWh as of April 2026 — about half what Ontario or Alberta customers pay. That low rate has historically made solar payback periods stretch past 25 years. In early 2026, Hydro-Québec changed the equation: it expanded net metering capacity limits from 50 kW to 1 MW and launched a $1,000 per kW installation grant. This guide covers the full Quebec compliance stack — net metering rules, RBQ and CMEQ licensing, municipal permitting in Montreal and Quebec City, and the step-by-step interconnection process.
Do Not Install Before Hydro-Québec Conditional Acceptance
Hydro-Québec requires pre-approval of your interconnection application before installation begins. Starting work before receiving conditional acceptance can result in application rejection and loss of grant eligibility. The $1,000/kW grant requires official grid connection authorization as proof of eligibility — installations done before Hydro-Québec approval may not qualify.
Net Metering and Grid Policy in Quebec
Program Overview
Hydro-Québec operates the sole electricity distribution network in Quebec outside of a small number of municipal redistributeurs. Its autoproduction program allows customer-generators to connect solar PV systems to the grid and offset their consumption through net metering. The program is governed by tariffs approved by the Régie de l’énergie du Québec — the independent regulator that oversees Hydro-Québec’s rates and service conditions under Quebec’s Loi sur la distribution de l’électricité.
In early 2026, Hydro-Québec made two major changes. First, it expanded the maximum eligible system capacity from 50 kW to 1 MW, making large commercial rooftop systems viable for the first time. Second, it launched a $1,000 per kW installation grant covering up to 40% of eligible project costs. These changes align with Hydro-Québec’s target of 125,000 autoproducers by 2035, representing approximately 3,000 MW of distributed generation.
Eligible Customer Types
Net metering is available to Hydro-Québec Distribution customers. Customers served by municipal redistributeurs — including Hydro Joliette, Hydro Coaticook, Hydro Saint-Jean, and approximately 10 others — are not eligible for Hydro-Québec’s program. Those redistributeurs operate separate policies.
| Tariff Class | Customer Type | Net Metering Option |
|---|---|---|
| Rate D (Tarif D) | Residential | Option I |
| Rate DM | Residential — master-metered | Option I |
| Rate G | Small business / commercial | Rate G net metering option |
| Rate AG | Agricultural | Eligible under autoproduction framework |
Large industrial customers on Rates M and L are subject to different interconnection agreements and are not covered under the standard net metering tariff.
System Size Limits
The 2026 expansion raised the program cap to 1 MW for all eligible customer types. Practical limits still apply based on connection type:
- Single-phase connections (typical residential at 120/240V): practical limit around 20 kW due to transformer and conductor capacity
- Three-phase connections (commercial and industrial at 347/600V): can reach 50 kW and above
- Systems approaching 1 MW: Hydro-Québec conducts a hosting capacity analysis to confirm the local distribution circuit can accept the generation without voltage or power quality issues
The system must generate from a renewable energy source. Eligible sources include solar photovoltaic, wind, small hydroelectric, geothermal electricity generation, and bioenergy. Diesel generators and natural gas do not qualify.
Credit Rate and 24-Month Bank
Hydro-Québec’s net metering operates as a kilowatt-hour offset, not a direct cash payment.
| Scenario | Compensation Mechanism |
|---|---|
| Solar production ≤ on-site consumption | No grid interaction — you consume what you generate |
| Solar surplus exported to grid | 1 kWh credit applied to next bill or accumulated in 24-month bank |
| Credits used within 24 months | Offset at retail rate (6.972¢/kWh block 1 or 10.756¢/kWh block 2) |
| Surplus credits after 24 months | Paid out at wholesale rate — approximately 6¢/kWh |
The 24-month bank reset is unique in Canada. Credits carry forward month to month with no monthly cash settlement. At the 24-month mark, Hydro-Québec resets the credit bank. Any remaining balance is converted to a cash credit at the wholesale rate and applied to the account. This means an oversized system accumulates surplus that gets paid out at roughly 6¢/kWh instead of offsetting bills at the retail rate. Size the system to match annual consumption.
Quebec’s Electricity Rate Context
Hydro-Québec’s Tarif D has two energy blocks effective April 1, 2026:
| Block | Threshold | Rate |
|---|---|---|
| Block 1 | First 40 kWh per day × billing days | 6.972¢/kWh |
| Block 2 | Remaining consumption above threshold | 10.756¢/kWh |
At 10.756¢/kWh for the second block, Quebec rates are roughly half of Ontario’s combined rate of approximately 17¢/kWh. Solar payback on rate offset alone is therefore slower — which is why the $1,000/kW grant matters. The grant effectively front-loads the savings and cuts typical residential payback from 25–30 years to 10–12 years.
Licensing Requirements in Quebec
RBQ Licence System
All construction work in Quebec falls under the RBQ (Régie du bâtiment du Québec). The RBQ issues construction licences to contractors in specific subcategories. For solar PV, three subcategories are relevant:
| Work Type | Required RBQ Subcategory |
|---|---|
| Solar panel mounting and racking (structural) | 11.2 or 13.5 |
| Electrical wiring, inverter connection, panel work | 16 (Electrical Contractor) |
| Turnkey solar contractor covering both | General licence 1.2 or 1.3 + qualified subcontractors, or all applicable subcategories |
Verify any contractor’s RBQ licence at rbq.gouv.qc.ca before signing a contract.
CMEQ: Master Electrician Requirement
Electrical contractors holding RBQ subcategory 16 must also hold a CMEQ (Corporation des maîtres électriciens du Québec) licence. The CMEQ is the professional self-regulating body for master electricians in Quebec. CMEQ membership can be confirmed at cmeq.org.
When hiring an electrical contractor for a solar project, confirm both RBQ subcategory 16 and CMEQ membership. A contractor with only an RBQ licence but without CMEQ membership is not legally authorized to perform electrical work in Quebec.
NABCEP certification is respected among Quebec solar installers but is not a legal requirement for licensing or grant eligibility.
Permitting in Quebec
Municipal Building Permits
The RBQ oversees contractor licensing but does not issue building permits. Building permits come from the municipality. In Quebec’s major cities:
| Municipality | Permit Authority | Notes |
|---|---|---|
| Montreal | Arrondissement where property is located | Each of Montreal’s 19 boroughs handles permits independently |
| Quebec City | Service des inspections, Ville de Québec | Online permit portal available |
| Laval | Direction des inspections | Rooftop solar typically requires a permit |
| Longueuil | Service d’urbanisme et du développement durable | Contact directly for requirements |
| Gatineau | Service de l’urbanisme | Permit required for structural modifications |
Some smaller municipalities may not require a building permit for rooftop solar if the installation does not alter the building envelope. Always confirm with the local municipality before starting work.
Electrical Permits and Inspection
An electrical permit is required before installation begins. The permit application is submitted through the licensed electrical contractor, who must include:
- A single-line diagram of the PV system
- Equipment specifications (inverter, modules, combiner, disconnect)
- Site plan showing panel and inverter locations
- Conductor sizing calculations
- Proof of contractor RBQ and CMEQ licences
After installation, the contractor conducts compliance testing and submits a signed verification report to Hydro-Québec. This report confirms the installation matches approved specifications, meets CSA C22.1 Section 64 requirements, and that all safety protections are functional. Hydro-Québec will not issue grid authorization without this report.
The Hydro-Québec Solar Grant
Grant Structure
Hydro-Québec launched the grant on March 31, 2026. It pays $1,000 per kW installed, up to 40% of eligible project costs.
| System Size | Estimated Gross Cost | Grant | Net Cost After Grant |
|---|---|---|---|
| 5 kW residential | $12,000–$15,000 | $5,000 | $7,000–$10,000 |
| 8 kW residential | $18,000–$22,000 | $8,000 | $10,000–$14,000 |
| 10 kW residential | $22,000–$27,000 | $10,000 | $12,000–$17,000 |
Eligibility Requirements
- Residential: Systems installed on or after June 30, 2025
- Commercial: Panels purchased after March 31, 2026
- Equipment: Panels must be CSA-certified (CSA 61215 / CSA 61730) and new — used or refurbished panels do not qualify
- Grid authorization: Official Hydro-Québec grid connection authorization is required as proof
- Submission deadline: 9 months from installation date
Residential customers apply through the LogisVert Efficient Homes Program. Commercial customers apply through the Efficient Solutions Program.
Federal Incentives for Quebec Businesses
For business customers, the federal Clean Technology Investment Tax Credit provides a 30% refundable tax credit on the capital cost of eligible solar property. This applies to assets placed in service after March 28, 2023, and is available to Canadian-controlled private corporations and other taxable entities. The federal ITC and the Hydro-Québec grant can be combined for commercial projects — they are not mutually exclusive.
Eligible assets also qualify for accelerated Capital Cost Allowance. Equipment acquired in 2026 falls under Class 43.1 with a 30% declining balance rate, plus enhanced first-year expensing of 100% for property available for use before 2030.

Technical Requirements
Inverter Certification
Inverters installed in Quebec must meet Canadian standards:
- CSA C22.2 No. 107.1 — inverter certification for utility interconnection
- Anti-islanding compliance — the inverter must disconnect from the grid within 0.1 seconds of detecting loss of Hydro-Québec supply
- CSA 61215 and CSA 61730 — module quality and safety standards required for LogisVert grant eligibility
Most major grid-tied inverter brands carry the required certifications. Confirm the specific model is certified before specifying it in a Quebec project.
Rapid Shutdown and Arc-Fault Protection
Under CSA C22.1 Section 64:
- Rapid shutdown: Required for rooftop arrays. The system must reduce array voltage below 30V within 30 seconds of activation. Module-level power electronics or dedicated rapid shutdown devices meet this requirement.
- Arc-fault circuit interruption (AFCI): Required per the 2024 Canadian Electrical Code for PV systems on buildings. Verify your inverter or combiner box includes AFCI functionality.
Metering
Hydro-Québec installs and owns the bidirectional meter for autoproduction customers. You do not pay a separate meter installation fee. Hydro-Québec updates your existing smart meter or installs a new bidirectional meter as part of the interconnection authorization process. You cannot begin exporting to the grid until Hydro-Québec confirms the bidirectional meter is active.
Common Compliance Mistakes in Quebec
| Mistake | Consequence | Correct Approach |
|---|---|---|
| Installing before Hydro-Québec conditional acceptance | Application may be rejected; grant eligibility lost | Submit autoproduction application and wait for conditional acceptance before starting work |
| Electrical contractor not CMEQ-licensed | Work may not be recognized; grid authorization refused | Verify both RBQ subcategory 16 and CMEQ membership before hiring |
| No municipal building permit for rooftop installation | Possible stop-work order; insurance or property sale issues | Confirm municipal requirements before installation |
| System oversized for consumption | Credits paid out at ~6¢/kWh after 24 months instead of offsetting at retail rate | Size system to match annual consumption |
| Panels not CSA-certified | Grant eligibility denied by LogisVert program | Specify only CSA-certified panels from eligible manufacturers |
| Grant application submitted late | Application rejected — 9-month window applies | Submit LogisVert grant application within 9 months of installation |
| Inverter lacks anti-islanding certification | Hydro-Québec will not authorize grid connection | Use only inverters certified to CSA C22.2 No. 107.1 |
| Serving a redistributeur’s territory | Customer is ineligible for Hydro-Québec autoproduction | Confirm the electricity distributor from the customer’s bill before designing |

Frequently Asked Questions
What is the maximum solar system size for Hydro-Québec net metering in 2026?
Hydro-Québec expanded its net metering program cap to 1 MW in early 2026, up from the previous 50 kW limit. This expansion applies to both residential and commercial customers. The practical limit for residential systems on single-phase connections is typically around 20 kW due to transformer capacity constraints, while three-phase commercial connections can go significantly higher. For systems approaching the 1 MW cap, Hydro-Québec conducts a hosting capacity analysis to confirm the local distribution circuit can accept the generation without voltage or power quality issues.
Do I need a license to install solar panels in Quebec?
Yes. Electrical work on solar installations requires a contractor licensed under RBQ subcategory 16 (Electrical Contractor). The contractor must also hold a CMEQ (Corporation des maîtres électriciens du Québec) licence. Structural mounting work requires RBQ subcategory 11.2 or 13.5. A general contractor (subcategory 1.2 or 1.3) can manage the project by subcontracting to licensed electrical and structural contractors. NABCEP certification is respected but not legally required.
How does Hydro-Québec credit solar exports?
Hydro-Québec credits exported kilowatt-hours at a 1-for-1 exchange against your retail electricity rate. Credits accumulate in a 24-month rolling bank and offset future consumption. Any unused credits after 24 months are paid out at the wholesale rate of approximately 6 cents per kWh. There is no monthly cash payment for exports. Because the payout rate is lower than the retail offset rate, correctly sizing your system to match annual consumption is more important in Quebec than in provinces with better surplus rates.
What permits are required for solar installation in Quebec?
Three permits or authorizations are typically required. First, Hydro-Québec must approve your interconnection application before installation begins. Second, your municipality issues a building permit for rooftop solar — Montreal, Quebec City, Laval, and Longueuil all require this. Third, the electrical installation must comply with CSA C22.1 Section 64 and be performed by an RBQ-licensed contractor. The RBQ does not issue building permits directly but oversees contractor licensing and work quality.
What is the Hydro-Québec solar grant and who qualifies?
Hydro-Québec launched a $1,000 per kW installation grant in March 2026, covering up to 40% of eligible project costs. Residential systems installed on or after June 30, 2025 qualify through the LogisVert Efficient Homes Program. Commercial systems with panels purchased after March 31, 2026 qualify through the Efficient Solutions Program. Eligible panels must be CSA-certified (CSA 61215 / CSA 61730) and new. You must have official Hydro-Québec grid connection authorization to apply, and you have 9 months from installation to submit the grant application.
