About Reserve Capacity Mechanism (RCM) API

The Reserve Capacity Mechanism (RCM) ensures the SWIS has sufficient available capacity to meet the peak demand. AEMO is responsible for assessing the capability of new or existing facilities to provide capacity.

The RCM Operations application provides functionality related to the RCM, including Certified Reserve Capacity applications, Non-Temperature Dependent Load applications, Individual Reserve Capacity Requirements, and Capacity Credit Allocations. 

Participants can interact with the RCM Operations application through the RCM Operations API and use features include importing/creating, updating and publishing RCM limit advice and constraint equations in bulk.
