Micro-generation

How much can I generate?

In Alberta, you can generate enough power to offset all, or a portion, of your annual energy usage.

Micro-generation systems like solar PV systems (less than 5,000 kW capacity and connected to an electric distribution system) produce electric energy for personal use. The energy produced must be less than the yearly consumption at the site.

Depending on how much you generate, you'll either be a small micro-generator (under 150 kW) or a large micro-generator (150 kW to 5,000 kW).

Note: Albertans who want to generate electricity to earn revenue and not for their own use are considered commercial generators and do not meet the micro-generator requirements.

What happens if I produce more energy than I use?

If you are a micro-generation customer and do not use all the energy produced in a billing cycle, you will receive a credit for any energy (measured in kWh) that you put onto the power grid.

Your credit will be dependent on the size of micro-generator you are. For example, a small micro-generator (up to 150 kW) will be credited at your retail energy rate. However, when your energy goes back into the grid, a large micro-generator (150 kW to 5,000 kW) will be credited at the average hourly Alberta Pool Price.

Alberta Electric System Operator determines the average hourly pool price. 

What if my energy use changes, and I want to change the capacity of my system?

Life changes, and your energy use may change with it. Your distribution company is responsible for working with you to determine the capacity of the micro-generator you can install today. Then, they can help you to consider future load additions. They may require evidence depending on the capacity increase requested.

Contact ATCO Electric for further assistance.

Who does what?

Your distributor is responsible for connecting your micro-generation system. The connection process follows the rules set out in the Micro-Generation Regulation and the Alberta Utilities Commission's (AUC's) Rules Respecting Micro-Generation. While your distribution company needs to follow the AUC's process, there may be slight variations.

Your distributor will also be responsible for meter installation and meter data management service to ensure the amount of energy sent to the grid is accurately accounted for. Meter installation is generally done at the distributor's cost, with a few exceptions. If there is a disagreement in cost responsibility, you can file a complaint with the AUC.

How do I qualify for micro-generation?

First, you must apply to your distribution company to connect your micro-generation unit. If you are a Direct Energy Regulated Services customer, you must reach ATCO Electric.

The size of your micro-generation unit cannot be larger than your site's historical consumption, meaning that you cannot generate more power than what you used the previous year. You can generate only enough to offset the amount used. After this, you are generating revenue and are considered a commercial generator.

Your distribution company will have guidelines explaining your responsibilities, including applying for permits from your municipality.

Review this handy guide from the AUC, which includes an application process summary on pages 10 to 13.
