The document discusses two projects related to improving collaboration on and updating the ETSAP-TIAM energy systems model. The ETSAP_TIAM Git project aims to enhance collaboration through a version control system to track model changes. The 2-year ETSAP-TIAM Update Project aims to ensure the model remains relevant by updating technologies, data, and scenarios through workshops and collaborative development among members. It will deliver an updated model, documentation, and standard scenarios in a new VEDA-BE database. A reviewer group was also announced to review proposed model changes.
