The Energy Technologies Institute (ETI) has developed an internationally peer-reviewed model of the UK's national energy system extending across power, heat transport and infrastructure. The Energy System Modelling Environment (ESME) is a policy neutral system-wide optimisation model. It models the key technology and engineering choices, taking account of cost, engineering, spatial and temporal factors. Key points: • A system-wide perspective, informed by modelling, is highly relevant because

The ETI's current ESME-based analysis of the UK energy system shows that • Decarbonisation can be achieved affordably (at around 0.6% of GDP), provided that the most costeffective technologies and strategies to reduce emissions are deployed • A broad portfolio of technologies is needed to deliver emissions reductions, with bio-energy and carbon capture and storage of particular system-wide importance Policy makers can use energy system modelling to inform market and policy design, increase understanding of pathways (including the impacts of 'real world' constraints and inertia in deploying technology), and identify key 'contender' technologies with particular system-wide value.
