Abstract

Renewable Energy Zones (REZ) are in the early stages of implementation in Australia's National Electricity Market (NEM) as a means of expediting transmission investment and facilitating new renewable generation capacity. This research explores the interrelationships and seasonal behaviour of nine proposed REZ across the Queensland region of the NEM. Assessment of the seasonal variable renewable energy supply and localised congestion effects, highlights the rapid increase in spilled energy that occurs as REZ subscription matures. Further, the contribution to the reliable supply of energy at a system level is considered through capacity value analysis and contextualised with their recent market performance. Important system planning considerations are highlighted, where analytical techniques are applied to the resource adequacy and congestion management problem.
