Net Metering in Ontario: Save on Solar Energy & Reduce Electricity Costs
Learn how Ontario’s net metering program works to reduce electricity costs for homeowners and businesses using solar energy. Discover benefits, eligibility, and tips to maximize savings.
Net metering in Ontario empowers homeowners and businesses to lower electricity bills and support clean energy by harnessing solar power. By sending surplus solar energy back to the grid and earning credits, participants can reduce costs while embracing sustainability. This guide explains how net metering works, its benefits, challenges, and why now is the time to invest in solar.
What is Net Metering?
Net metering is a renewable energy program regulated by the Ontario Energy Board (OEB). It allows individuals with solar PV systems to generate electricity for their own use while exporting surplus energy to the grid. Participants earn credits to offset future electricity consumption.
Key Features of Net Metering in Ontario
Energy Credits: Unused credits from surplus energy can be carried forward for up to 12 months.
Grid Connection: Remain connected to the utility grid for continuous power during low solar production.
Eligibility for Solar Energy Systems: Systems must generate electricity primarily for on-site use.
How Net Metering Works: A Step-by-Step Process
Solar Energy Generation: Solar panels convert sunlight into electricity to power your home or business.
Exporting Surplus Energy: Excess electricity flows into the grid, earning you credits.
Earning Credits: These credits are applied to your utility bill, reducing future electricity costs.
Annual Credit Expiry: Unused credits expire after 12 months, making it essential to size your system appropriately.
Eligibility and Requirements for Net Metering in Ontario
To participate in the program, your solar PV system must meet the following requirements:
Compliance with Standards: Adhere to technical and safety regulations set by the OEB.
Grid Connection Agreements: Sign agreements with your Local Distribution Company
(LDC) and undergo an inspection process.
System Ownership or Leasing: You can own your system outright or lease it through
Power Purchase Agreements (PPAs).
Benefits of Net Metering in Ontario
- Lower Electricity Bills: Reduce energy costs by generating your own electricity and offsetting high-consumption months with credits.
- Environmental Sustainability: Transition to renewable energy, reducing reliance on fossil fuels, and lowering carbon emissions.
- Property Value Increase: Homes with solar energy systems are more attractive to eco-conscious buyers, boosting marketability and resale value.
- Grid Resilience: Decentralized energy generation strengthens the grid by diversifying power sources.
- Job Creation: Net metering stimulates demand for solar energy systems, creating opportunities in the renewable energy sector.
Challenges and Considerations for Net Metering
- Upfront Costs: Solar PV system installation can be expensive. However, federal incentives like Canada’s Greener Homes Initiative provide financial support.
- System Sizing: Oversized systems may lead to wasted credits, while undersized systems may not fully meet your energy needs. Work with a professional to design an appropriately sized system.
- Seasonal Variability: Solar energy production fluctuates with weather and seasons, affecting available credits during winter months.

Net Metering and Policy Updates
Ontario’s net metering program is governed by O. Reg. 541/05, with oversight from the Ontario Energy Board. Since its introduction in 2005, the program has undergone updates to make renewable energy more accessible.
