Transmission Capability Map

This interactive map illustrates transmission capability—the estimated additional generation capacity that could be connected at different locations on the existing transmission system. It assists market participants to make informed business decisions for generation capacity and location siting to facilitate optimizing the transmission system. The current version illustrates the capability in the South and Central East regions.  

These capability values are technology agnostic and are evaluated based on the existing transmission system with historical data. The evaluation does not consider future load, generation, and transmission system developments and operations. 

Capability values are based on category A thermal congestion and could be further limited by contingencies, other constraints or other connection projects. These values are indicative and not guaranteed in the AESO Connection Process. Favourable locations have capabilities exceeding the project size, while locations with limited capability or capability smaller than the project size may lead to complex connection requests.

Visit Connecting to the Grid for information on the AESO Connection Process—the official process to facilitate market participants’ requests for new or altered system access services on Alberta’s transmission system.
