1/5 of Australian households have a DER system, and it's growing

The Australian power market operator (AEMO) and the coalition of transmission and distribution companies (Energy Networks Australia) realize that high amount of DER penetration has great potential for providing an array of system benefits, as well as potential for system malfunctions and inefficiencies if not properly managed. They have recently published a study reviewing the state of DER in Australia and its potential. More interestingly, the study reviews three alternatives for how to manage DER from a system-wide perspective. Their three options include (1) a Single Integrated Platform with AEMO optimizing dispatch including network constraints; (2) a Two Step Tiered Platform, in which Distribution System Network Providers perform distribution-level dispatch within their own networks; and (3) an independent Distribution System Operator, which is similar to option 2, except that bed aggregators would provide bids to the iDSO, and the iDSO would aggregate those bids to each transmission connection point. Each has their pros and cons. As we in the US continue to look for the best way to transform our power sector, we would be wise to see how the Australian system unfolds.
