Program Description

Incentive program covering up to 90% of eligible costs for energy-efficiency, electrification, and demand-management projects at commercial, institutional, industrial, and agricultural facilities on the Hydro-Québec grid. Refreshed to version 5.1 on March 31, 2025 with enhanced cold-climate heat-pump incentives and a formal pivot toward electrification of fossil-fuelled process heat. Prescriptive ('simplified') pathway via the OSE online tool for standard measures; customized pathway for complex or innovative projects. Projects can claim up to $5 million and $60,000 separately for energy analysis support.

Eligibility Requirements

  • Commercial, institutional, industrial, or agricultural facility located in Quebec
  • Hydro-Québec business customer (or customer of eligible alternative electricity source)
  • Facility uses electricity for the retrofitted end-use, OR project electrifies an existing fossil-fuel process
  • Project measures result in verifiable energy savings, demand reduction, or electrification of process heat
  • Project is implemented in the applicant's own building or operations
  • Equipment meets Hydro-Québec's efficiency specifications (for prescriptive measures) or passes a custom-measure technical review

How to Win

Insider tips, common pitfalls, and what successful applicants look like

Premium
Insider Tip

The OSE 5. 1 refresh materially increased cold-climate heat-pump incentives and made electrification of fossil-fuel process heat a first-class use case — if your Quebec operation still runs natural-gas boilers, process heaters, or oil-fired dryers, the custom path can now cover a large share of the switchover cost. Start by using the OSE tool on Hydro-Québec's site to get a quick incentive estimate for any prescriptive measures; this establishes the baseline. For anything bigger or novel, request an energy advisor meeting early — the separate $60K energy-analysis incentive can pay for the feasibility study that shapes the custom project. Budget is finite annually, so file prescriptive applications in Q1 (January–March) and launch custom-project discussions early in the calendar year to secure a spot.

Premium See what trips up most applicants for this program — and how to avoid it.

Success Profile

A Quebec commercial, institutional, industrial, or agricultural Hydro-Québec business customer replacing aging HVAC, lighting, or process equipment with high-efficiency alternatives — or switching a fossil-fuel process (boiler, process heater, dryer, glycol heat) to electrified technology. Facility has clear baseline energy data, a defined project scope with vendor quotes, and the capital resources (or financing plan) to cover the 10%+ non-incentivized portion. Repeat Hydro-Québec program participants have an edge on custom projects due to familiarity with M&V requirements.

Premium See what successful applicants for this program actually look like.

Evaluation Criteria

Prescriptive measures evaluated against published equipment-efficiency specifications and verified installation — no competitive scoring; all qualifying applications are approved. Custom measures evaluated on: (1) Energy savings or demand-reduction magnitude and persistence; (2) Electrification of fossil-fuel processes (prioritized under OSE 5.1); (3) Quality and credibility of the measurement-and-verification plan; (4) Cost-effectiveness (incentive per kWh saved or kW reduced); (5) Alignment with Hydro-Québec's annual efficiency and electrification targets.

Premium 7 steps 8 docs

Application Steps

1 Use the OSE Online Tool Visit hydroquebec.com and launch the OSE tool. Enter facility, equipment, and measure details to get an instant estimate of available prescriptive incentives. If all your measures are prescriptive, this is the fastest path.
2 Determine Pathway If your measures are standard (LED, HVAC replacement with listed equipment, prescriptive heat pumps), proceed on the simplified / prescriptive path. If the project involves process electrification, non-standard equipment, or complex controls, request a meeting with a Hydro-Québec energy advisor for the custom path.
3 Prescriptive — Submit via OSE Submit the application through the OSE tool with equipment specs, vendor quotes, and baseline data. Receive incentive reservation typically within 4–8 weeks.
4 Custom — Energy Analysis For custom projects, complete an energy analysis or feasibility study (often incentivized separately up to $60K). Work with a Hydro-Québec advisor to define the scope, baseline, measurement-and-verification methodology, and incentive calculation.
5 Custom — Participant Agreement Execute a participant agreement defining the scope, incentive amount, M&V plan, installation deadline, and post-install reporting requirements. Incentive is formally reserved at this stage.
6 Install and Verify Install the equipment, document installation, submit completion reports (invoices, commissioning, photos). Hydro-Québec verifies installation and pays the incentive — typically 6–12 weeks after complete submission.
7 Post-Install M&V (Custom Only) For custom projects, submit measurement-and-verification data per the agreed schedule (often 12 months of post-install metering). Final incentive payments or true-up adjustments occur after M&V.

  • Residential equipment or housing-focused retrofits
  • Routine maintenance, repair, or like-for-like replacement without efficiency gain
  • Costs recoverable through standard utility rates or bundled in another Hydro-Québec program
  • Demolition or site-preparation costs unrelated to the efficiency measure

Intake Periods

Continuous intake (no deadline). Budget envelopes are annual; apply early in Hydro-Québec's fiscal year for highest approval probability on custom projects.

Deadline Notes

No fixed deadline. Program operates on a continuous-intake basis. Hydro-Québec reviews applications as received. Budget envelopes are set annually — apply early in Hydro-Québec's fiscal year (January–March) for highest approval probability on larger custom projects. OSE 5.1 is the current version (in effect since March 31, 2025) and supersedes OSE 5.0.

Clawback Risk

Low Risk

Hydro-Québec can require repayment if equipment is removed, decommissioned, or replaced with less-efficient equipment before the end of the measure's useful life, or if post-installation measurement-and-verification reveals significantly lower energy savings than claimed. For most prescriptive measures, clawback risk is low.
