The CELSIUS City Consortium is going to deploy 12 new technically and economically innovative demonstrators. Another up to 20 state-of-art demonstrators (already in operation) will proof the CELSIUS City Concept covering the full FP7 8.8.2 requirements.CELSIUS has a clear strategy and a pro-active approach to Market Outreach, which will strive to commit 50 new cities to the CELSIUS Roadmap by the end of 2016. When fully implemented, this will lead to 20-45 TWh reduction in the use of primary energy p.a.CELSIUS City is well positioned to deliver those targets due a strong partnership of major front running European cities and their respective utilities, and further outstanding innovative organizations, with track records both in creating technically and economically innovative demonstrators, as well as in understanding and overcoming the barriers for large scale deployment (e.g. Imperial College (UK), SP (S), TU Delft (NL), Cologne University of Applied Sciences (D), D’Appalonia (IT), LSE (UK)).CELSIUS has eight work packages targeting on the successful deployment of the 13 new demonstrators (WP3), supported by a collaborative approach to harvest beyond state-of-the-art insights from Tech & Innovation (WP5) and Stakeholder Acceptance (WP6). The local demonstrator perspective is enriched by the Integration & Roadmap (WP2). The final goal for Communication & Market Outreach (WP8) is based on developing the CELSIUS in the Market Uptake (WP7). A powerful project management office (WP1), seconded by rigor monitoring (WP4), coordinates all work packages and assuring over the time of the CELSIUS Consortium, both impactful deployment and sustainable market outreach.The total cost of the CELSIUS 13 new demonstrators is 69m EUR, of which the cities themselves will provide 55m EUR. The requested EU funding enables these activities laying the foundation for the successful large scale deployment of the CELSIUS City Concept across Europe and beyond 2020.
