This paper examines the mechanical degradation, failure mechanisms, and system-level reliability implications of Australia’s ageing coal-fired power generation assets, focusing on Callide Power Station (Queensland) and Yallourn Power Station (Victoria). Both stations have experienced significant mechanical failures in the past five years, exposing vulnerabilities in maintenance, asset management, and risk governance under conditions of declining … Continue reading Engineering Integrity, Failure Evolution, and Energy Transition: A Mechanical Engineer’s Perspective on Australia’s Ageing Coal Fleet
