What is micro-generation?
The Micro-Generation Regulation  allows Albertans using renewable resources or alternative energy, to generate their own environmentally friendly electricity to receive credit from any excess electricity they send into the electricity grid. The intent of the regulation is for the micro-generator to be self-sufficient.

When the regulation was passed, the AUC oversaw the implementation of the regulation as well as developed processes to simplify approvals and interconnection agreements with customers and wire service providers. More detailed information on the process and rules on micro-generation in Alberta can be found in AUC Rule 024: Rules Respecting Micro-Generation.

In Alberta, a “micro-generation generating unit” means a generating unit of a customer that:

(i) Exclusively uses sources of renewable or alternative energy.

(ii) Is intended to meet all or a portion of the customer’s total energy consumption at the customer’s site or aggregated sites.

(iii) Has a total nameplate capacity that does not exceed the lesser of 5 MW or the rating of the customer’s service.

(iv) Supplies electric energy only to a site that is located on property that the customer owns or leases.

(v) Is located

(A) On the property referred to in subclause (iv), or

(B) on property that the customer owns or leases that is adjacent to the property referred to in subclause (iv)

Two categories of micro-generation:

Small micro-generation
The micro-generation generating unit has a total nameplate capacity of less than 150 kW and is metered using a bi-directional cumulative meter. A small micro-generator receives a credit from its retailer for any electric energy supplied back to the grid at the retailer’s retail energy rate.

Large micro-generation
The micro-generation generating unit has a total nameplate capacity of greater or equal to 150 kW but not exceeding 5 MW and is metered using a bi-directional interval meter. A large micro-generator receives a credit from its retailer for any electric energy supplied back to the grid at the hourly pool price for each hour

Owners of electrical distribution systems, such as ATCO Electric, FortisAlberta, EPCOR Distribution and Transmission and ENMAX Power Corporation are responsible for connection services for micro-generators.

Do you qualify as a micro-generation customer?
Prospective generation project proponents should refer to the checklist below to determine which generation category they belong to.

1. Determine the generating unit capacity:

a) If the generating unit capacity is greater than or equal to 5-MW, then follow procedures stated in Rule 007: Applications for Power Plants, Substations, Transmission Lines, and Industrial System Designations to submit an application to the AUC for approval.

b) If the generating unit capacity is less than 5 MW proceed to step 2.

2. If the generating unit is less than 5 MW, then:

a) Check to ensure the generating unit is meeting the micro-generation requirements set out in subsection 1(1)(h) of the Micro-Generation Regulation.

How to become a micro-generator in Alberta?

• Become familiar with the contents of the AUC’s Rule 024: Rules Respecting Micro-Generation, which will help you understand the process and technical requirements of interconnecting your micro-generation unit to the distribution system.

• Refer to Section 3 of Rule 024 for the steps involved when submitting a micro-generation notice to your wire service provider (your wire service provider is responsible for reviewing and processing your micro-generation notice).
• Please see the AUC micro-generation notice submission guideline for more information on how to become a micro-generator in Alberta. Please note the content of the guideline is in the process of being updated to reflect the recent changes made to the Micro-Generation Regulation.

Questions on micro-generation projects should be directed to your local wire service provider.
