SPR developed a portfolio-wide electrification and energy upgrade pathway for Queensland’s social housing stock, moving from detailed stock baselining through to intervention modelling and whole-of-portfolio cost–benefit analysis. A bottom-up archetype model was constructed to reflect dwelling type, climate zone, construction era, existing upgrades and fuel mix, enabling robust baseline estimates of electricity and gas consumption, peak demand, energy bills and emissions across a geographically dispersed and diverse portfolio.
Priority interventions were identified through a structured longlisting and shortlisting process, and included electrification of hot water and cooking, appliance upgrades, rooftop solar (including for apartments), community batteries and virtual power plant participation, along with contracting models. Each measure was evaluated for average and total program net present value, benefit–cost ratio, bill impacts and emissions outcomes, with sequencing logic applied to test staged rollout aligned with asset replacement cycles. The final report translated this analysis into a clear, staged implementation roadmap, setting out how the Department could practically deliver the program at scale.
