This report presents in brief the development and content of the Pan-European Thermal Atlas (Peta), with focus on the current update in response to project deliverable 6.5, which concerns for the final levels of district heating for each of the 14 member states to be recommended in WP6.

The update refers to data that has been rendered in work package 2 (WP2) and consists of three main parameters: a high-resolution model of the heat demand and its density; the specific investment costs for district heating systems, and allocated volumes of industrial and energy sector excess heat for current and prospective district heating areas. All of these parameters represent spatially derived information that has been provided as data matrices to the energy systems modelling colleagues in WP6, as a basis for their assessment of national heating and cooling scenarios for the 14 member states (deliverable 6.4).

In terms of dynamic maps, a new dynamic layer, labelled: Recommended DH levels, has been added to the Peta 4.2 online web map application on August 31, 2018, where it now is publicly available. This new layer contains recommendations to develop district heating at the local scale, based on current heat demand densities, temporally and spatially accessible excess heat from industries, from waste-to-energy facilities, from current power plant locations, and in terms of access to locally available renewable energy resources.

In November 2018, the Pan-European Thermal Atlas is scheduled for a comprehensive update, rendering the third version (Peta 4.3), to be released at the 4th International Conference on Smart Energy Systems and 4th Generation District Heating conference (SES4GDH) in Aalborg, Denmark, on November 13-14. Apart from several other new dynamic layers to be introduced in this coming update (see sub-section 1.2.3), the new layer on recommended district heating levels, added here to the current Peta 4.2, will also be part of this general update.
