Use energy before exporting it
The closer production aligns with building loads, the more energy is used directly instead of relying on future credits.

Hydro Ottawa net metering: use, export and credit.
Exported renewable energy can create a non-cash bill credit; it is not a cash payment for all production.
Under Hydro Ottawa net metering, solar production serves the building first. Eligible excess generation exported to the grid creates a non-cash credit under the applicable rate plan, subject to connection and program rules.

Understand the 12-month rule

Obtain approvals before operation
Grid capacity, Hydro Ottawa assessment, ESA requirements and municipal permits must be completed before connection.

Frequently asked questions
Frequently asked questions
Are generation credits paid in cash?
No. Hydro Ottawa describes them as non-cash credits that cannot be redeemed as payment for other services.
Can battery storage be paired with a net-metered system?
Hydro Ottawa says storage may be paired with an eligible renewable energy technology; storage by itself does not qualify.
What happens during an outage?
Standard grid-tied solar shuts down for safety. Backup requires compatible islanding equipment, controls and usually a battery.
