If you're planning to install rooftop solar in Ottawa or Casselman, your approval process runs through Hydro Ottawa. For residential systems rated 10 kilowatts AC or less (classified as micro-generation in Ontario), Hydro Ottawa manages grid capacity review, service layout quotes, bi-directional meter installation, and final energization authorization.
Understanding Hydro Ottawa's micro-generation connection process is essential for avoiding delays, budgeting accurately for costs, verifying grid capacity at your location, and securing timely approval. This comprehensive guide breaks down exactly what homeowners and installers need to know: connection fees, approval timeline, required documents, restricted feeders, and how to check if your street can host solar exports.
Who Is Hydro Ottawa?
Hydro Ottawa is the local electricity distributor (LDC) responsible for delivering power to Ottawa and Casselman. It operates the local distribution network — the "wires" system that connects homes to Ontario's provincial electricity grid.
Hydro Ottawa's Role in Solar Connection
- Reviews grid capacity at your property's feeder
- Issues official Service Layout (feasibility quote)
- Installs or replaces meter with bi-directional model
- Authorizes system energization and net metering
Governance & Regulation
- Wholly owned by the City of Ottawa
- Governed by an independent board
- Regulated by the Ontario Energy Board (OEB)
- All solar installations must meet Electrical Safety Authority (ESA) requirements before energization
For solar homeowners, Hydro Ottawa is the authority that approves net metering connections, specifies technical requirements, processes applications, and manages the bi-directional meter installation.
Micro-Generation Connection Process (≤10kW AC)
Hydro Ottawa classifies projects 10kW AC or less as micro-generation. Below is the real-world approval flow that homeowners and installers must follow:
Step 1: Submit Service Request
Apply online to Hydro Ottawa and select Net Metering as your connection type. Hydro Ottawa reviews:
- • Your property's location and feeder
- • Feeder hosting capacity
- • Proposed generator type (solar)
- • Estimated system output (capacity)
Step 2: Feasibility & Service Layout Issuance
If the grid can host your system, Hydro Ottawa issues a Service Layout (Customer Layout Quote) that includes:
- • Utility responsibilities and your responsibilities
- • Official connection cost quote
- • Technical requirements
- • Timeline for completion
Published Timeline:
- • Minimum: 15 days
- • Maximum: 60 days for complex cases
- • Service Layout validity: 90 days
Step 3: Pay Hydro Ottawa Charges
Hydro Ottawa requires payment of all quoted charges before work begins. Typical micro-generation costs:
| Item | Amount |
|---|---|
| LDC Bi-Directional Meter | $899.00 |
| Customer Service Layout Fee | $491.87 + HST |
| Total (est. with HST) | ~$1,446.81 |
⚠️ Note: These are project-specific estimates. Your official Service Layout will include exact charges for your property.
Step 4: Complete Installation & ESA Approval
Your installer builds the solar system. You must obtain authorization from the Electrical Safety Authority (ESA).
Critical: Hydro Ottawa will not energize your system without an ESA safety inspection and approval certificate.
Step 5: Sign Connection Agreement
Return the signed Connection Agreement to Hydro Ottawa. This formalizes your commitment and Hydro Ottawa's responsibilities.
Step 6: Bi-Directional Meter Installation & Energization
Hydro Ottawa schedules meter installation and:
- • Replaces or upgrades to a bi-directional meter
- • Energizes your system
- • Activates net metering on your account
- • Begins recording exports to the grid

How to Check Grid Capacity Before Designing Solar
Grid capacity is the most critical variable in the solar approval process. Hydro Ottawa evaluates every distributed energy resource (DER) for hosting capacity. Some feeders have limited capacity due to short-circuit constraints and cannot accept new exports.
Hydro Ottawa Restricted Feeders List
Hydro Ottawa publishes a "List of Restricted Feeders" due to short-circuit constraints. If your property is connected to a restricted feeder, the utility may refuse to authorize solar export.
🚨 Restricted Feeder Examples
These feeders typically have limited or no hosting capacity:
- • Ellwood MTS feeders (ELW series)
- • AF02–AF04
- • AQ02–AQ04
- • UA05–UA07
- • UZ05–UZ12
- • Additional feeders (varies by year)
Fast Pre-Check Method
Option 1: Google Search

Hydro Ottawa Micro Net Metering FAQ
How long does Hydro Ottawa take to review a micro solar request?
Hydro Ottawa states it will issue a Service Layout within 15 to 60 days if sufficient grid capacity exists at your location. Utility-side work (meter installation) typically takes approximately 4 weeks. Total approval-to-energization time ranges 6–12 weeks depending on feeder capacity results, ESA inspection timing, and payment on schedule.
Do I need a bi-directional meter?
Yes. Hydro Ottawa requires replacement of your standard meter with a bi-directional meter to record both electricity imported from the grid and exported back to the grid. This enables net metering functionality.
Can I receive cash for excess power?
No. Hydro Ottawa offers billing credits only — not cash payments. Excess electricity you export earns credits that offset your future electricity bills on a 1:1 kilowatt-hour (kWh) basis.
Do credits expire?
Yes. Ontario's net metering rules require that credits must be used within 12 months. Any unused credits after 12 months are forfeited. Plan your system size to maximize summer exports without accumulating excess credits.
How do I know if my street has capacity?
There are two ways to check:
- 1. Review Restricted Feeder List: Check Hydro Ottawa's published list of restricted feeders (see above for search method). If yours appears, capacity may be limited.
- 2. Submit Service Request: The only definitive answer comes from submitting a formal Service Request to Hydro Ottawa. Their engineering team will assess your specific property location.
What is a Service Layout?
A Service Layout (also called Customer Layout Quote) is Hydro Ottawa's official feasibility assessment and cost estimate for connecting your solar system. It includes:
- • Utility responsibilities and your responsibilities
- • Itemized connection costs (meter, installation, etc.)
- • Technical requirements specific to your property
- • Timeline for work completion
Validity: The quote is valid for 90 days. After that, it expires and you must reapply.
Are there monthly net metering service charges?
No. Hydro Ottawa currently does not charge a monthly service fee for net metering beyond the initial connection cost and meter installation. Your bill reflects imports from the grid minus exports (net calculation), but there is no recurring "net metering fee."
