This paper reviews and evaluates key policy initiatives and strategies designed to strengthen regional economic, social and environmental outcomes in the Latrobe Valley (Victoria, Australia) in the three years following the closure of the Hazelwood power station. Prior to its sudden closure in March 2017, Hazelwood was the most carbon-intensive electricity generator in Australia. The debate over the future of Hazelwood became an icon in the nation’s ongoing political struggle over climate and energy policy. Employment and economic outcomes in the three years since closure indicate promising initial progress in creating the foundations required to facilitate an equitable transition to a more prosperous and sustainable regional economy. The Hazelwood case study provides support for a number of propositions about successful regional energy transition including that well managed, just transitions to a prosperous zero-carbon economy are likely to be strengthened by proactive, well integrated industry policy and regional renewal strategies; respectful and inclusive engagement with workers and communities; and adequately funded, well-coordinated public investment in economic and community strategies, tailored to regional strengths and informed by local experience.
