Abstract

Although most progress on decarbonisation in the UK has been made in the power sector, heat accounted for 44% of total energy consumption and approximately 37% of GHG emissions in 2017. Given the efficiency and cost-competitiveness of the incumbent gas-based system, decarbonising the heat sector signals a transition that requires judicious planning and defensible policy intervention. We present a novel spatially explicit MILP model for integrated optimisation of heat and power to assess the implications of heat electrification. For the first time, real-world regional hourly heat demand data are employed and the optimal share of regional heat electrification is explored by taking into account operational and investment decisions. Finally, we propose the concept of heat carbon budgets to assist policy interventions and systematically assess the transition to a low-carbon heat system.
