E3-MODELLING AE

Their core work

E3-Modelling is a Greek SME specializing in energy-economy-environment modelling and integrated assessment. They develop and operate quantitative models that simulate how climate policies, energy transitions, and decarbonization pathways affect economies and societies. Their core work involves building decision-support tools that help policymakers evaluate trade-offs between emissions reduction targets, energy system transformation, and socio-economic impacts. Across 18 H2020 projects, they consistently provide the analytical backbone — running scenarios, projecting energy demand, and assessing policy feasibility at both national and global scales.

What they specialise in

How they've shifted over time

In their early H2020 period (2015–2018), E3-Modelling focused on broad climate policy analysis — global mitigation pathways, mid-century strategies, NDC assessment, and macro-level integrated assessment modelling. From 2019 onward, their work shifted noticeably toward granular energy demand modelling, sector-specific analysis (households, transport, industry, buildings), and emerging societal trends like digitalisation, prosumer behaviour, circular economy, and shared economy impacts on energy systems. This evolution shows a clear trajectory from "big picture" global climate scenarios toward applied, sector-level energy transition analysis with stronger attention to behavioural and societal dimensions.

Moving from macro-level climate scenarios toward granular, behaviour-aware energy demand modelling that accounts for digitalisation, circular economy, and societal change — expect future work to blend IAM with behavioural and machine learning approaches.

How they like to work

E3-Modelling operates exclusively as a participant, never leading consortia — they are the modelling engine that other organisations build projects around. With 221 unique partners across 41 countries, they maintain an exceptionally broad collaboration network, indicating they are a sought-after specialist rather than a project initiator. Their consistent presence in large RIA consortia (15 of 18 projects) suggests they are a trusted, reliable modelling partner that integrates well into multi-disciplinary teams.

Remarkably well-connected for an SME, with 221 unique consortium partners spanning 41 countries — covering virtually all of Europe plus global partners. Their network is heavily concentrated in energy and climate research institutions, with strong ties across Western and Southern Europe.

What sets them apart

E3-Modelling occupies a rare niche: a small private company whose quantitative models are trusted by dozens of Europe's leading climate and energy research consortia. Unlike university modelling groups, they bring commercial discipline and continuity; unlike large consultancies, they offer deep, specialised model development rather than generic advisory services. Their 18-project track record with EUR 6.8M in funding demonstrates sustained demand for their specific modelling capabilities — a consortium builder seeking credible energy-climate quantification would find few alternatives with this combination of specialisation, flexibility, and network reach.
