Micro-generation customers remain connected to the distribution system so they can obtain electrical power when needed and also receive credit from their retailer for any power exported to the electricity grid. The micro-generation system is intended to meet all or a portion of the customer’s total energy consumption. For micro-generation customers, our focus is to ensure that the interconnection is safe for the customer, the public, and does not negatively affect power quality or reliability for other customers. FortisAlberta provides the bi-directional meter for qualified micro-generators, and in most instances, will cover the grid connection costs.
In Alberta, micro-generation is generally defined by its size:
Small: 0 kW to 150 kW
Large: 150 kW to 5 MW
The vast majority of micro-generators fit into the “small” category. At this level, customers may potentially generate enough electricity to power some or all of their home or small business. Some customers may be able to aggregate multiple sites to further offset consumption.
Small micro-generators will receive a credit for energy exported (kWh) based on the same rate used for purchases from their electricity retailer. Large micro-generators will receive a credit based on the hourly pool price. Distribution, transmission and other costs are included separately. The monthly bill customers receive from the retailer is adjusted based on the net difference between the energy supplied into the micro-generation site and energy exported from the site for a net charge or credit.
