The Socio-Economic Energy Model for Digitalization (SEED) quantifies digitalization's impacts on technology investment choices, energy consumption, and emissions in different energy sectors. It belongs to the class of Agent Based Models and simulates the decision processes of various heterogenous actors of the energy system: households, services sectors and industry sectors. These decision processes relate to the adoption of digital services and practices, as well as the investment in end-use energy technologies to support them. The model represents a large set of complex interactions between its actors, such as peereffects, producer-consumer relationships and employee-employer relationships. It can also be linked to the Swiss TIMES energy system model (STEM) to evaluate broader implications to the energy supply and infrastructure arising from the decisions of the SEED actors. The current article formally describes the SEED model based on the Overview Design Concept and Details (ODD) protocol. It also lists its main features, assumptions and data sources.
