National Energy System Modelling


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 National Energy System Modelling and Analysis, which draws on the internationally peer reviewed Energy System Modelling Environment (ESME) tool to inform and support Government energy strategy and planning policy.

Whole system modelling 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 Asset

Energy Systems Catapult works in collaboration with academia and industry to offer expert National Energy System Modelling and Analysis – drawing on the internationally peer reviewed Energy System Modelling Environment (ESME) asset.

We 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.

Our Approach

The Modelling team can offer:

  • Whole System Modelling and Analysis – providing an understanding of energy systems from a national and regional level, to reveal the most cost-effective transition pathway to a smarter, lower carbon, decentralised and flexible energy system. We collaborate with academic and industry partners, to gain access to a range of software-based energy system planning and modelling tools.
  • Project development and delivery – using whole system modelling and analysis outputs to help decision-makers put strategies and action plans together for different transition pathways available, including economic benefits and the latest innovations.
  • Expert advice and collaboration – to promote greater cohesion across the sector, by actively encouraging businesses, policymakers, regulators and investors to take a whole system perspective.
