About Guy

Guy joined ACIL Allen in 2022 as a Principal, bringing fifteen years of experience in analysing the Australia's transition to cleaner energy sources. He specialises in bringing together economic modelling and policy analysis to help governments, regulators and industry navigate this transition.

Guy has worked for both state and national governments providing advice on policy options to decarbonise the energy sector. This advice has been underpinned by extensive modelling of the electricity and gas sectors, including low-emissions supply options and fuel substitution and energy efficiency options on the demand-side.

While with independent think-tank Grattan Institute between 2018 and 2021, Guy co-authored high-profile reports and major newspaper opinion pieces on topical aspects of the energy transition, including how to manage energy reliability in the wake of the South Australian state-wide blackout, how to strike a balance between government intervention and market-led investment, low-emissions industrial options for Australia's future such as green steel and ammonia, and the future of gas in Australia's energy mix.

Between 2010 and 2015 Guy advised Australian and international clients while with ACIL Allen and Vivid Economics on a range of energy-related projects.

Guy holds a Master of Resource and Environmental Economics from the Australian National University, and bachelor’s degrees in Arts (majoring in Politics with first class honours) and Economics from The University of Adelaide.
