Transmission and Distribution

​A Secondary Network is a complex power grid with a web of multiple parallel sources of power to each customer. The benefit for customers connected to these systems is they should rarely experience interruptions in power. The design of a Secondary Network does NOT allow customers to export power to the grid due to safety and technical reasons.

Within the city of Calgary, ENMAX Power has four Secondary Networks. Please refer to the Network boundary maps for more information.

Network Boundary Maps:

• Network Boundary - Downtown
• Network Boundary – Chinook Centre
• Network Boundary – Westbrook Mall
• Network Boundary – North Hill Mall

Generators interconnecting to the ENMAX Secondary Network Systems will be required to comply with the following:

• Network Inverter‐based Micro‐generation Design Requirements
• Network Servicing Policies and Guidelines
