In Toronto, all rooftop solar must be formally connected through Toronto Hydro's generation and storage connection process. This comprehensive guide covers everything from net metering mechanics to neighborhood coverage, connection fees, grid capacity verification, and step-by-step approval timelines, ensuring you have complete information to move forward confidently.
How Toronto Hydro Net Metering Works
Toronto Hydro's Net Metering Program is the financial engine that makes residential solar worthwhile in the city. It allows homeowners to send excess electricity generated by solar panels back into the grid in exchange for bill credits. These credits offset your future electricity costs on a kilowatt-hour basis, and any unused credits carry forward for up to 12 months.
1:1 Credit Basis
Every kilowatt-hour (kWh) you export to the grid earns exactly 1 kWh credit on your Toronto Hydro bill.
12-Month Carry Forward
Unused summer credits accumulate and apply to your bill for up to 12 months, allowing winter heating costs to be offset by summer solar production.
Eligibility Requirements for Toronto Hydro Net Metering
- Primary Use: Electricity must be generated primarily for your own use (residential consumption)
- Export Capability: Excess energy can be exported back to Toronto Hydro's grid
- Technical Compliance: Your site must meet Toronto Hydro's technical and safety specifications
- Service Area: Your property must be within Toronto Hydro's distribution network (all Toronto addresses qualify)

Toronto Hydro Solar Connection Process (Step-by-Step)
Toronto Hydro's official generation and storage connection process unfolds in clear, sequential stages. Here's what to expect:
Step 1: Preliminary Capacity Check
Timeline: 1-2 weeks
Email a Preliminary Consultation Information Request (PCIR) to DER@torontohydro.com to get an early assessment of grid capacity and feasibility before committing to equipment.
Step 2: Application Submission
Timeline: 1-2 weeks to assemble
Submit Micro-Embedded Generation Facility Application with technical drawings, inverter/panel datasheets, and application fee ($500 + HST) confirmation.
Step 3: Connection Agreement
Timeline: 1-2 weeks for review
Toronto Hydro issues Connection Agreement. You sign and return with connection fee payment ($635.94 + HST). Agreement outlines specifications and technical conditions.
Step 4: Installation
Timeline: 1-3 weeks
Begin construction per Toronto Hydro's Service Layout Report. Your installer works to specification and coordinates with utility as needed.
Step 5: ESA Inspection
Timeline: 1-2 weeks
System inspected and certified by Electrical Safety Authority (ESA). Send ESA Certificate of Compliance to Toronto Hydro for final verification.
Step 6: Meter Installation
Timeline: 1-2 weeks
Toronto Hydro schedules and installs bi-directional meter (net meter) required for net metering, which tracks both consumption and export.
Step 7: Connection Complete & Net Metering Active
Your system is live!
After final checks, your system officially connects to the grid and starts earning net metering credits immediately.
Total Expected Timeline: 4–8 weeks
Depending on documentation completeness, approvals, and local grid capacity.
How to Check Grid Capacity for Your Toronto Solar System
Before committing to solar equipment and contracts, verify your local grid capacity — whether the distribution system can safely accept your solar generation without restrictions or downsizing.

Use Toronto Hydro Capacity Maps
Toronto Hydro provides a Load Capacity Map showing available capacity levels across its network. Searching "Toronto Hydro Grid Capacity Map" can lead you to tools clarifying whether a specific transformer or feeder has available capacity for your system.
Why This Matters:
In rare cases, if the local grid transformer is at capacity, Toronto Hydro may require system downsizing or impose generation limits. Confirming capacity early avoids unexpected restrictions, costly redesigns, or delays.
