Quebec has some of the cheapest electricity in North America — Hydro-Québec’s Tarif D residential rate sits at roughly 6.97–10.76¢/kWh as of April 2026, compared to 15–25¢/kWh in Ontario or British Columbia. That low baseline rate has historically made solar payback periods long in Quebec, sometimes exceeding 25–30 years. In April 2026, Hydro-Québec changed that equation with a $1,000/kW installation grant — cutting typical residential payback to 10–12 years. This guide explains the autoproduction (self-generation) program rules, net metering credit structure, RBQ and CMEQ licensing requirements, and the step-by-step Hydro-Québec interconnection process as of April 2026.

System Size Limits Are in Transition

Hydro-Québec has proposed increasing residential net metering limits from 20 kW to 100 kW and commercial limits from 50 kW to 1 MW. These increases require Régie de l’énergie approval. As of April 2026, the approved limits remain 20 kW (single-phase) and 50 kW (three-phase) for most customers. Do not design or quote a system above these thresholds without first confirming current approved limits with Hydro-Québec’s autoproduction team — a system designed for an unapproved size will be rejected at the interconnection application stage.

Hydro-Québec Net Metering: Program Rules

Program Background

Hydro-Québec began allowing small customer-generators to connect to its distribution grid under a formal net metering framework following regulatory decisions by the Régie de l’énergie du Québec — the independent body that approves Hydro-Québec’s tariffs and service conditions under Quebec’s Loi sur la distribution de l’électricité (Electricity Distribution Act). The net metering tariff options (Option I for residential Rate D customers, and a parallel option for Rate G commercial customers) were established to enable on-site renewable generation to offset grid consumption.

Quebec’s autoproduction program differs from Ontario’s or BC’s in one important respect: because Hydro-Québec itself is a very large, low-cost hydroelectric generator, the province has historically had little urgency to incentivize distributed solar. Quebec’s residential electricity rates have been among the lowest in Canada for decades, which suppresses the economic return from solar. The $1,000/kW grant launched March 31, 2026 marks the first substantial provincial financial incentive for grid-tied residential solar in Quebec’s history.

Hydro-Québec’s stated target is 125,000 electricity autoproducers by 2035 — representing approximately 3,000 MW of distributed generation across Quebec. The grant program is the primary mechanism to reach that target.

Eligible Customer Types

Net metering is available to customers whose electricity bill lists Hydro-Québec Distribution as their distributor. Customers served by municipal electric redistributeurs — Hydro Joliette, Hydro Coaticook, Hydro Saint-Jean, and approximately 10 other local distributors in Quebec — are not eligible for Hydro-Québec’s autoproduction program. Those redistributeurs operate separate net metering policies, several of which also offer mesurage net (net metering) for their customers.

Eligible tariff classes for net metering Option I:

Tariff ClassCustomer TypeNet Metering Option
Rate D (Tarif D)ResidentialOption I
Rate DMResidential — master-meteredOption I
Rate GSmall business/commercialRate G net metering option
Rate AGAgriculturalEligible 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

Under current Régie de l’énergie-approved tariffs:

  • Single-phase connections (typical residential at 120/240V): maximum 20 kW of installed generating capacity
  • Three-phase connections (commercial and industrial at 347/600V): maximum 50 kW

Hydro-Québec filed for Régie de l’énergie approval to increase these limits to 100 kW (residential) and 1,000 kW (commercial and industrial). Once approved and in effect, these expanded limits would allow substantially larger residential and C&I installations to participate in net metering. Watch Hydro-Québec’s autoproduction page and the Régie de l’énergie’s published decisions at regie-energie.qc.ca for confirmation.

The system must generate from a renewable energy source. Eligible sources include solar photovoltaic, wind, small hydroelectric (including hydroliennes), geothermal electricity generation, and bioenergy. Diesel generators and natural gas do not qualify.

Credit Rate Structure

Hydro-Québec’s net metering Option I operates as a kilowatt-hour offset, not a direct cash payment per exported kWh.

ScenarioCompensation Mechanism
Solar production ≤ on-site consumptionNo grid interaction — you consume what you generate, reducing your bill directly
Solar surplus exported to Hydro-Québec grid1 kWh credit applied to your next bill or accumulated in the 24-month bank
24-month bank — credits used within 24 monthsOffset at your applicable retail rate (6.972¢/kWh block 1 or 10.756¢/kWh block 2, effective April 1, 2026)
Surplus credits remaining after 24 monthsPaid out by Hydro-Québec at the wholesale rate — approximately 6¢/kWh

The key distinction from other Canadian utilities: Hydro-Québec does not pay you a fixed cents-per-kWh rate for each exported unit every billing cycle. Credits accumulate as kWh units in your account. Because the 24-month payout rate (wholesale, ~6¢/kWh) is substantially lower than the retail rate you offset during normal months, designing a system that matches annual consumption rather than overshooting it is more important in Quebec than in provinces with better surplus rates.

Annual Settlement and the 24-Month Rollover

Credits from exported electricity carry forward month to month with no monthly settlement or cash payment. At the 24-month mark, Hydro-Québec resets the credit bank. Any remaining kWh balance is converted to a cash credit at the wholesale rate and applied to your account. This arrangement means:

  • A correctly sized system — one that generates roughly as much electricity per year as the household consumes — will use most of its credits through winter consumption and owe little at the 24-month reset.
  • An oversized system accumulates surplus that gets paid out at ~6¢/kWh instead of offsetting bills at the retail rate, significantly reducing the financial return.

Use solar design software to model annual generation against annual load before finalizing system size. Getting that sizing ratio right is more consequential in Quebec than in higher-rate provinces.

Quebec’s Electricity Rate Context

Hydro-Québec’s Tarif D (Rate D) — the standard residential rate — has two energy blocks effective April 1, 2026:

BlockThresholdRate
Block 1 (low consumption)First 40 kWh per day × billing days6.972¢/kWh
Block 2 (higher consumption)Remaining consumption above threshold10.756¢/kWh

There is also a fixed daily customer charge. The rate increased 3% on April 1, 2026, continuing a multi-year pattern of modest annual increases approved by the Régie de l’énergie.

At 10.756¢/kWh for the second block, Quebec rates are roughly half of what residential customers pay in Ontario (≈ 17¢/kWh combined) or Manitoba (≈ 12¢/kWh). Solar payback in Quebec purely on rate offset is therefore slower — which is exactly why the $1,000/kW grant is significant. The grant effectively front-loads the savings.

Technical Requirements

Inverter Certification

Inverters installed in Quebec for grid-tied solar must meet Canadian standards. Hydro-Québec requires:

  • 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. This protects Hydro-Québec line workers from back-energized lines during outages.
  • CSA 61215 and CSA 61730 — module quality and safety standards required for LogisVert grant eligibility. Panels must be CSA-certified and new (not used or refurbished).

Most major grid-tied inverter brands (SolarEdge, Enphase, Fronius, Huawei, SMA) 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 (Renewable Energy Supply Systems) — the section of the Canadian Electrical Code governing solar and other distributed generation:

  • Rapid shutdown: Required for rooftop arrays. The system must reduce array voltage below 30V within 30 seconds of activation. Module-level power electronics (MLPEs) 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, or specify a dedicated AFCI device.

Metering

Hydro-Québec installs and owns the bidirectional (net) 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 — this happens after your installation is verified and authorized. You cannot begin exporting to the grid until Hydro-Québec confirms the bidirectional meter is active.

Hydro-Québec Distribution Code Requirements

Hydro-Québec publishes technical guidelines for distributed generation connections. For residential systems up to 20 kW:

  • The inverter must be a grid-dependent type — it only operates when Hydro-Québec grid power is present. Stand-alone or hybrid inverters that can island are subject to additional review.
  • For larger commercial systems (approaching the 50 kW limit), Hydro-Québec may require a hosting capacity analysis to confirm the local distribution circuit can accept the generation without voltage or power quality issues. In some cases, grid reinforcement work may be required at the customer’s cost — though this is rare for small residential systems.

Step-by-Step: Hydro-Québec Solar Connection

1

Verify eligibility and confirm Hydro-Québec is your distributor

Check your electricity bill — the distributor must be Hydro-Québec Distribution (not a local redistributeur). Confirm your rate class (Rate D, DM, G, or AG). Check that your proposed system size is within current approved limits: 20 kW for single-phase residential, 50 kW for three-phase commercial. Review Hydro-Québec’s autoproduction page at hydroquebec.com/autoproduction for any updates to limits pending Régie de l’énergie approval. For the $1,000/kW grant, residential panels must have been installed on or after June 30, 2025; for commercial, panels must have been purchased after March 31, 2026.

2

Engage a licensed CMEQ electrical contractor and design the system

For the electrical portion of the installation, you need a contractor with RBQ subcategory 16 and CMEQ membership. Verify the contractor’s RBQ licence number at rbq.gouv.qc.ca/en/online-services/licence/verify-a-licence. Confirm the inverter is CSA C22.2 No. 107.1-certified and that panels carry CSA 61215/61730 certification if you plan to apply for the LogisVert grant. Use solar design software to model the system against annual Hydro-Québec consumption, confirm shading, and produce the one-line diagram required for the interconnection application. Size the system to match annual consumption — avoid significant over-generation given the low (~6¢/kWh) 24-month surplus payout rate.

3

Submit the Hydro-Québec interconnection application — before installation

Submit an autoproduction connection request through Hydro-Québec’s self-generation portal at hydroquebec.com/autoproduction/devenir-client-producteur.html. Required information: customer account number, civic address, proposed capacity in kW, inverter model and specifications, and a system one-line diagram. Hydro-Québec evaluates grid hosting capacity at the point of connection. For most standard residential projects, this review results in conditional acceptance within a few weeks. Do not purchase or install equipment before receiving conditional acceptance — installations done before approval may be ineligible for the grid authorization and grant.

4

Apply for municipal building permit and proceed with installation

Most Quebec municipalities require a building permit for rooftop solar installations. In Montreal, apply to the arrondissement where the property is located through the online permit portal at montreal.ca. In Quebec City, use ville.quebec.qc.ca. In Laval, Longueuil, and other cities, contact the service de l’urbanisme directly. Permit fees and processing times vary by municipality — allow 1–4 weeks in most cases. Once the permit is issued, your contractor installs the system in compliance with CSA C22.1 Section 64 and Hydro-Québec’s technical requirements. Panel mounting must comply with the applicable building code (CNBC as adopted in Quebec).

5

Complete compliance verification and send report to Hydro-Québec

After installation, the licensed electrical contractor (CMEQ master electrician) conducts compliance testing and signs a verification report confirming the installation matches the approved specifications, meets CSA C22.1 requirements, and that anti-islanding, rapid shutdown, and AFCI protections are functional. This signed report is submitted to Hydro-Québec. Hydro-Québec may also require a municipal inspection completion certificate depending on the municipality. The verification report is the critical document — Hydro-Québec will not issue grid authorization without it.

6

Receive grid authorization and apply for the grant

Once Hydro-Québec confirms the verification report is satisfactory, it issues official grid connection authorization. Your meter is updated for bidirectional measurement — in most cases this is done remotely without a site visit. The system can then export to the grid and net metering credits begin accumulating. With the grid authorization in hand, submit your grant application: residential customers apply through the LogisVert Efficient Homes Program at hydroquebec.com/residential/energy-wise/financial-assistance/logisvert/residential.html. You have 9 months from your installation date to submit. Commercial customers apply through the Efficient Solutions Program (OSE calculation tool).

Licensing in Quebec: CMEQ and RBQ Requirements

The RBQ Licence System

All construction work in Quebec — including solar installations — falls under the RBQ (Régie du bâtiment du Québec), the provincial building regulatory authority. The RBQ issues construction licences to contractors in specific subcategories. For a solar PV project, two subcategories are typically relevant:

Work TypeRequired RBQ Subcategory
Solar panel mounting and racking (structural installation)11.2 (Specialty Equipment and Products Contractor) or 13.5 (Special or Prefabricated Installations)
Electrical wiring, inverter connection, panel work16 (Electrical Contractor)
Turnkey solar contractor covering bothGeneral licence 1.2 or 1.3 + qualified subcontractors, or all applicable subcategories

Verify any contractor’s RBQ licence number before signing a contract at rbq.gouv.qc.ca. An unlicensed contractor’s work may not be recognized by Hydro-Québec or your municipality, and any warranty claims or insurance coverage could be affected.

The CMEQ: Quebec’s Master Electrician Body

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, established under provincial law. The CMEQ:

  • Sets and enforces professional standards for electrical contractors in Quebec
  • Maintains a public directory of licensed master electricians at cmeq.org
  • Requires member firms to carry commercial general liability insurance
  • Oversees continuing education requirements

When hiring an electrical contractor for a solar project in Quebec, always confirm both their RBQ licence (subcategory 16) and their CMEQ membership. A contractor with only an RBQ licence but without CMEQ membership is not legally authorized to perform electrical work in Quebec.

NABCEP (North American Board of Certified Energy Practitioners) certification is respected and often found among Quebec solar installers but is not a legal requirement for licensing or grant eligibility.

Municipal Permit Requirements

The RBQ oversees contractor licensing but does not issue building permits. Building permits come from the municipality. In Quebec’s major cities:

MunicipalityPermit AuthorityNotes
MontrealArrondissement where property is locatedEach of Montreal’s 19 boroughs handles permits independently
Quebec CityService des inspections, Ville de QuébecOnline permit portal available
LavalDirection des inspectionsRooftop solar typically requires a permit
LongueuilService d’urbanisme et du développement durableContact directly for requirements
GatineauService de l’urbanismePermit required for structural modifications

Some smaller municipalities may not require a building permit for rooftop solar, particularly if the installation does not alter the building envelope. Always confirm with the local municipality before starting work — do not assume a permit is unnecessary.

The Economics of Solar in Quebec

Why Low Rates Change the Math

Quebec solar economics are different from the rest of Canada. With Hydro-Québec’s block rates at 6.97–10.76¢/kWh (April 2026), the value of each kWh offset by solar is lower than in Ontario (≈ 17¢/kWh), Alberta (≈ 19¢/kWh), or British Columbia (≈ 13¢/kWh). A 10 kW system in Quebec generating 10,000 kWh/year offsets roughly $1,075 worth of electricity at the second block rate — compared to $1,700 in Ontario for the same generation.

Without the grant, payback periods in Quebec ran 25–30 years for residential solar — longer than most panel warranties. The $1,000/kW grant changes the calculation significantly:

SystemGross Cost (est.)GrantNet CostAnnual Savings (est.)Payback
5 kW residential$12,000–$15,000$5,000$7,000–$10,000~$540/yr13–18 years
8 kW residential$18,000–$22,000$8,000$10,000–$14,000~$860/yr12–16 years
10 kW residential$22,000–$27,000$10,000$12,000–$17,000~$1,075/yr11–16 years

Note: Savings estimates assume the second-block rate (10.756¢/kWh) and full self-consumption of generation. Actual savings depend on consumption patterns, system orientation, local shading, and net metering credit usage. Use a generation and financial tool to model project-specific payback for Quebec clients.

Federal Clean Technology Tax Credit

For business customers, the federal Clean Technology Investment Tax Credit (Clean Tech ITC) provides a 30% refundable tax credit on the capital cost of eligible solar property, including panels, inverters, and related equipment. This credit applies to assets placed in service after March 28, 2023, and is available to Canadian-controlled private corporations and other taxable entities.

Eligible assets also qualify for accelerated CCA (Capital Cost Allowance) under Class 43.1/43.2, allowing 100% write-off in the first year for solar equipment. The federal ITC and the Hydro-Québec $1,000/kW grant can be combined — they are not mutually exclusive for commercial projects. This stacking makes commercial solar in Quebec substantially more attractive than the residential math alone suggests.

Quebec Provincial Programs

There is no Quebec provincial solar tax credit or income tax incentive separate from the Hydro-Québec grant as of April 2026. The grant is the primary provincial-level financial support. Hydro-Québec’s broader energy efficiency programs (LogisVert for residential, Efficient Solutions for commercial) include the solar grant as one eligible measure alongside other energy efficiency improvements.

The federal Green Technology financing under BDC (Business Development Bank of Canada) and EDC (Export Development Canada) programs may also be available for commercial solar projects, but these are debt instruments, not grants.

Frequently Asked Questions

Does Hydro-Québec offer net metering for solar panels?

Yes. Hydro-Québec’s autoproduction program includes a net metering option for eligible residential (Rate D, DM) and commercial (Rate G) customers. Surplus solar electricity is credited to your account as kilowatt-hours, offsetting future consumption. Unused credits after 24 months are paid out at the wholesale rate (~6¢/kWh). In April 2026, Hydro-Québec launched a $1,000/kW installation grant that substantially improves the financial case for solar in Quebec’s low-rate market.

What is the maximum solar system size for Hydro-Québec net metering?

Under current Régie de l’énergie-approved tariffs: 20 kW for single-phase residential connections and 50 kW for three-phase commercial or industrial connections. Hydro-Québec has proposed expanding these to 100 kW (residential) and 1,000 kW (commercial) — but this requires regulatory approval and has not been confirmed for all customers as of April 2026.

What license do I need to install solar in Quebec?

Electrical work requires a contractor with an RBQ licence (subcategory 16) and CMEQ membership. Panel mounting requires RBQ subcategory 11.2 or 13.5. Verify both licences before hiring a contractor. NABCEP certification is recommended but not legally required.

How does Hydro-Québec credit solar exports?

Exported kWh offset your retail electricity bill at a 1-for-1 rate. The credit value is your applicable Tarif D rate — 6.972¢/kWh for the first block or 10.756¢/kWh for the second block (April 2026 rates). Credits accumulate over 24 months. Any balance remaining at 24 months is paid out at the wholesale rate (~6¢/kWh). There is no monthly cash payment for exports — the mechanism is a kWh offset bank.

Do I need an RBQ permit for solar installation in Quebec?

The RBQ does not issue building permits directly, but licensed contractors must hold RBQ licences to perform the work legally. The building permit comes from your municipality — most Quebec municipalities require one for rooftop solar. Hydro-Québec’s interconnection authorization is also required and is separate from municipal permits.
