Check All Your IncentivesWho Qualifies
Both programs are open to Ontario commercial and industrial electricity customers.
Commercial / Industrial Facility
Warehouses, manufacturing, cold storage, retail, offices, hotels, schools, hospitals, agricultural, and multi-residential buildings.
Ontario LDC Customer
Connected to a Local Distribution Company (Toronto Hydro, Hydro One, Hydro Ottawa, etc.). This covers the vast majority of Ontario — only a few municipal utilities operate outside the IESO-controlled grid. Owners or lessees with written authorization.
Taxable Canadian Corporation
Federal ITC requires Canadian incorporation. 40% refundable for CCPCs and other taxable corporations. Equipment must be new and situated in Canada.
Application Timing
Save on Energy: submit Retrofit application before signing a purchase order. 24 months from pre-approval to complete the project.
Available Province-Wide Across Ontario
Save on Energy Retrofit is available to every commercial property connected to an Ontario Local Distribution Company. The Federal ITC applies Canada-wide. Solenery checks your specific LDC and matches all eligible programs automatically.

From Application to Rebate
Sequencing matters. Save on Energy must be applied for before any binding commitment.
Contact Your Local Utility
Confirm connection capacity and Retrofit availability with your LDC (Toronto Hydro, Hydro One, Hydro Ottawa, etc.).
Submit Save on Energy Retrofit Application
Create an account on the IESO Retrofit Portal. Submit your solar PV application before signing any purchase order or contract.
Get Pre-Approval, Then Proceed
Once pre-approved, select your installer and sign contracts. 24 months to complete the project.
Receive Save on Energy Rebate
After installation is verified, the rebate is paid directly. For a 200 kW system: up to $172,000.
Claim the Federal ITC
File CRA Schedule 31 with your next corporate tax return. 30% of gross equipment cost. Corporations receive 40% as a refund; the rest offsets taxes owed or carries forward up to 20 years.
Why 2026 Is the Window
Ontario commercial electricity rates surged while incentives remain at peak levels. See the full business case →
Electricity Rates Up 28–68%
OEB rate increases effective November 2025 hit commercial customers hardest. Solar payback periods are shorter than ever.
ITC Drops to 15% After 2033
The 30% rate applies for equipment available for use before January 1, 2034. Then 15% for one year, then zero.
Retrofit Budget Is Finite
The program runs on a fixed budget per LDC. Once committed, new applications may be deferred.
Panel Prices Near Record Lows
Solar module costs declined through 2025–2026. Combined with peak incentives and rising rates, ROI is at its best.
