To transform the energy system to meet UK carbon reduction targets and achieve our clean growth ambitions, it is crucial to understand the costs and benefits of different technologies, system designs and decarbonisation pathways.

Energy Systems Catapult offers expertise in modelling and analysis of the Whole System, from national level, to regional, local and individual building level. Whole System modelling also considers the complex interactions of power, gas, heat, and transport and the different ways in which our energy might be supplied, managed and consumed in the future.

The Challenge and Opportunity

Transforming the UK energy system to be clean, secure and affordable, requires an in-depth understanding of the costs and benefits of different options and choices from a Whole System perspective, to aid policy and investment decisions.

Whole Systems modelling and analysis is used to understand how the entire UK energy system, and the constituent parts within it, might interact and collectively contribute to delivering lowest-cost overall energy system transitions. By looking at the Whole System, a collaborative environment can be encouraged where innovations progress more quickly from prototype to marketplace, which itself promotes economic benefits.

Our Assets

The Catapult develops and manages three key modelling assets:

  • National Energy System Modelling and Analysis – drawing on the internationally peer reviewed Energy System Modelling Environment (ESME) tool to inform and support Government energy strategy and planning policy.
  • Local Energy System Modelling and Analysis – applying the EnergyPath® Networks (EPN) local area energy planning tool, to inform and support local authorities and Local Enterprise Partnerships with cost effective low carbon energy transition.
  • Building Energy System Modelling and Analysis – utilising the Home Energy Dynamics (HED) tool to understand the interactions between different domestic heating systems, controls, building fabric, weather and consumer needs.

Our Approach

Energy Systems Catapult works in collaboration with academia and industry to offer expert modelling and analysis on the planning and design of future low carbon energy systems. We deliver insights on the costs and benefits of different choices from across the whole energy system, which supports government and industry in making the right policy and investment decisions.

The Modelling team can offer:

  • Whole System modelling and analysis – providing an understanding of energy systems from a national, regional, local and individual building level, to reveal the most cost-effective transition pathway to a smarter, lower carbon, decentralised and flexible energy system.
    Collaborating with academic and industry partners to gain access to a range of software-based energy system planning and modelling tools. These deliver independent and unbiased evidence to support policy-making by government, decision making relating to national and local energy system infrastructure for local authorities, networks, etc.. and more effective targeting of innovation investment by businesses and government.
  • Project development and delivery – using the Whole System modelling and analysis outputs and helping decision-makers put strategies and action plans together based on the different transition pathways available, in order to deliver economic benefits, including the latest innovations.
  • Expert advice and collaboration – promoting greater cohesion across the sector, by actively encouraging businesses, policy-makers, regulators and investors to take a Whole System perspective.
    We provide expert insights so that policy-makers and decision-makers can take account of a broader range of evidence, to better understand the costs and benefits of different technologies, system designs and pathways towards a smarter low carbon future.
