Alberta utilities have a Net Billing program. Rather than crediting for electricity usage, Net Billing offers a monetary credit for each kWh delivered to the street. The rate varies between retailers, but the export rate will match the rate you purchase electricity from the retailer at. Customers do not receive a credit for the transmission and distribution portion of the electricity imported, but if a home uses most of the solar electricity produced rather than exporting it, the customer gets the benefit of reduced T&D charges overall.Click here for a nice visual of the net billing process.
