Each year in January, AEMO calls for expressions of interest from new generation or demand side management (DSM) facilities that may seek certified reserve capacity and capacity credits for the relevant capacity year. This allows AEMO to compile information on upcoming projects, and enables prioritisation of facilities, if required, when assigning capacity credits. Submissions for this process close on the first business day in May, and AEMO publishes a summary of results by mid-May.
An expression of interest does not place any obligations on the proponent or AEMO.
