Use the OSE calculation tool to request financial support

Projects must be submitted to Hydro‑Québec only after the work has been completed. However, the OSE tool will estimate the amount of financial support to which you may be entitled for the measures implemented.

Hydro‑Québec will acknowledge receipt of your project and assess its compliance. You may be asked to provide additional information. Please refer to the Energy‑efficient Equipment for Businesses page for more information.
