Alectra Utilities Solar Connection Guide: Cities Served, Net Metering, Fees & Grid Capacity

Alectra Utilities is one of Ontario’s largest local electricity distributors, serving over one million customers across the Greater Toronto and Hamilton Area (GTHA). Homeowners connected to Alectra Utilities can install solar panels and participate in Ontario’s net metering program, allowing them to generate clean electricity and receive bill credits for excess power sent back to the grid.

This guide explains:

• Which cities Alectra Utilities serves
• How solar net metering works with Alectra
• Typical solar connection fees
• Grid capacity and system limits
• Whether solar is worth it for Alectra customers

⚡ Quick Fact: Alectra serves some of Ontario’s fastest-growing communities where electricity demand and delivery charges continue to rise—making rooftop solar a highly practical way to reduce long-term hydro bills.

Alectra Utilities provides electricity service to major Ontario cities and regions, including:

• Brampton
• Mississauga
• Vaughan
• Markham
• Richmond Hill
• Hamilton
• Burlington
• Oakville
• Milton
• Georgetown (Halton Hills)
• Ajax
• Pickering
• Whitby
• Aurora
• Newmarket

These fast-growing urban and suburban areas see rising electricity demand, which makes rooftop solar an increasingly popular option for reducing monthly hydro bills.

Yes. Alectra Utilities supports residential and commercial solar installations under Ontario’s Net Metering Regulation (O. Reg. 541/05).

Solar customers connected to Alectra Utilities can:

• Generate electricity from rooftop solar panels
• Export excess solar power to the grid
• Receive bill credits for surplus production
• Offset future electricity usage in later billing periods

Net metering credits can typically be carried forward for up to 12 months.

✅ Bottom Line: You can legally connect solar to Alectra’s grid and earn credits for excess energy—your system just needs to pass Alectra’s connection approval process.

Alectra Utilities requires solar systems to go through a formal connection approval process. Costs may include:

• Application and technical review fees
• Bi-directional meter installation
• Electrical inspection and commissioning
• Potential transformer or feeder upgrades

Typical Alectra solar connection costs range from $500 to $2,000, depending on:

• Solar system size
• Local grid capacity
• Electrical upgrades required
• Location within Alectra’s service area

Final costs are confirmed during the connection assessment.

What Drives Connection Costs?

• System size (kW): Larger systems may trigger additional review
• Feeder capacity: Saturated circuits may require upgrades
• Transformer age: Older transformers sometimes need replacement
• Local grid constraints: Dense neighborhoods may have export limits

Grid capacity refers to how much distributed generation (like rooftop solar) the local grid can safely accept. In some Alectra Utilities service zones:

• Transformer capacity may limit export size
• Feeder circuits may reach saturation
• High solar adoption areas may face longer approval times

Alectra Utilities may:

• Limit system size
• Require infrastructure upgrades
• Delay approvals in saturated areas
• Enforce export caps for safety

Checking grid capacity early helps prevent project delays and unexpected upgrade costs.

Under Ontario’s net metering program, Alectra Utilities customers can:

• Send excess solar electricity to the grid
• Receive kilowatt-hour (kWh) credits
• Use credits to offset future electricity usage
• Balance summer production with winter consumption

Credits usually expire after 12 months, so most systems are designed to match annual energy use rather than exceed it.

For a deeper breakdown, see How net metering works in Ontario.

For many Alectra Utilities customers, solar is financially worthwhile due to:

• Rising Ontario electricity rates
• High urban delivery charges
• Federal and provincial incentives
• Net metering bill credits

Most households connected to Alectra Utilities can offset 50% to 100% of their annual electricity usage depending on:

• Roof size and orientation
• Sunlight exposure
• Energy consumption patterns

Typical payback periods range from 7 to 11 years, followed by decades of reduced electricity costs.
