Net metering lets solar customers export surplus electricity to the grid and receive credit against future usage.
When your solar system produces more electricity than your home or business is using, the surplus flows back to the grid through your existing utility connection. Under net metering, that surplus is credited against electricity you draw from the grid later, such as at night or during low-production winter months.
Each local utility, whether Alectra Utilities, Toronto Hydro, Oakville Hydro, Burlington Hydro or Kitchener-Wilmot Hydro, administers its own net metering application and interconnection review. Terawatt Solar submits this paperwork on your behalf as part of every installation, so you are not navigating the process alone.
Billing cycles and credit rollover rules vary by utility. Your account representative at Terawatt Solar will walk through exactly how net metering will show up on your specific utility's bill before your system goes live.
