Counteracting the duck curve: Prosumage with time-varying import and export electricity tariffs

Energy Policy, 2025, vol. 198, issue C

Abstract: Australia is a frontrunner in household solar photovoltaic (PV) adoption, which has helped to accelerate the energy transition but has changed demand such that the power system faces operational challenges, known as the solar ‘duck curve’. The growing adoption of household batteries will change demand once again and policymakers have the means to reshape this demand through time-varying tariffs. This study evaluates the impact of time-varying import and export tariffs on household load profiles using data from 400 Melbourne households, each equipped with a 9 kWPPV and 12 kWh battery, and a dispatch optimisation model.
