The report that could kill wind power

A little noticed study by AEMO released late last year might become the key weapon for those intent on putting a stop to the growth of wind power and other renewables. The study was a good one for its purpose but can be easily misinterpreted.

Editor's Introduction: With another review of the Renewable Energy Target commencing we felt it was important to revisit the results of a modelling exercise assessing potential wind power grid integration technical issues undertaken by the Australian Energy Market Operator back in late 2013. This study attracted little attention but gave strikingly different answers to prior modelling exercises, suggesting greater grid integration costs for levels of wind consistent with achieving the Renewable Energy Target. While this study was fine for its purpose of helping AEMO to explore potential technical changes that might be required to manage high levels of wind penetration, it made simplifying assumptions that made it unsuitable for assessing the likely economic costs of achieving the Renewable Energy Target. To head off the potential for this study to be misinterpreted and misused in the forthcoming review of the Renewable Energy Target, we asked Jenny Riesz to provide this review of the report.
