Quick answer
With net metering, you sign an agreement with your utility, send the renewable electricity you don't use to its grid, and receive credits on your bill. Credits offset the electricity you use, can't be applied to other charges, and carry forward for up to 12 months before dropping to $0.1
Step by step
- Install an eligible renewable system, such as rooftop solar.
- Enter into a net metering agreement with your local utility.1
- When your system produces more than your home uses, the extra flows to the grid.
- Your utility bills you for the electricity you take from the grid and credits you for what you send.1
The rules to know
- Credits only offset electricity consumption charges (the kWh you use), not other charges on your bill.1
- Credits carry forward for up to 12 months, after which unused credits are reduced to $0.1
- The program is set by Ontario Regulation 541/05.1
Designing for net metering
Because unused credits expire, it usually makes sense to size solar close to what your home uses over a year rather than far beyond it. A battery can store daytime production to use in the evening instead of exporting it.
Before you apply: rebate programs can have their own rules for systems that export power, so we check net metering and rebate requirements together.
Common follow-up questions
Does Ontario pay cash for extra solar power?
Under net metering you receive bill credits for power sent to the grid, which carry forward for up to 12 months.
Can net metering credits pay my delivery charges?
No. Credits can only offset charges related to the electricity you consume.
