This rule-change is designed to improve the financial viability of a range of decentralised energy projects involving local councils, shopping centres, office buildings, apartments, precinct scale co- and tri-generation, community energy and aggregated small scale solar and storage.

In terms of how the methodology for cost reflectivity should be applied, and how transaction costs should be accounted for, PIAC joins the proponents in calling upon the AEMC to contribute to the data pool and assist in providing the necessary evidence-base to make a comprehensively informed decision.
