As part of the EU H2020 Smart Cities and Communities project POCITYF, the cities Alkmaar (NL) and \u00c9vora (PT) aim to support the deployment and market uptake of such districts and in doing so demonstrate innovative and integrated technologies to enable flexibility in the energy system. This paper addresses implementation conditions for energy flexibility technologies that help cities to engender the expected impact and ensure replication of these technologies to other sites. It aims to guide both urban planners and technology solution providers through pitfalls and opportunities that can appear during the design and implementation of PEDs. Taking this into consideration, the RUGGEDISED innovation and implementation framework for smart city technology was taken as a starting point to describe and analyze the experiences in Alkmaar and \u00c9vora.<\/jats:p>","DOI":"10.3390\/en13215811","type":"journal-article","created":{"date-parts":[[2020,11,6]],"date-time":"2020-11-06T09:03:04Z","timestamp":1604653384000},"page":"5811","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Implementation Framework for Energy Flexibility Technologies in Alkmaar and \u00c9vora"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0120-9386","authenticated-orcid":false,"given":"Nienke","family":"Maas","sequence":"first","affiliation":[{"name":"TNO\u2014Netherlands Organization of Applied Scientific Research, NL-2595 DA, 96800 The Hague, The Netherlands"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6697-5802","authenticated-orcid":false,"given":"Vasiliki","family":"Georgiadou","sequence":"additional","affiliation":[{"name":"TNO\u2014Netherlands Organization of Applied Scientific Research, NL-2595 DA, 96800 The Hague, The Netherlands"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5841-8886","authenticated-orcid":false,"given":"Stephanie","family":"Roelofs","sequence":"additional","affiliation":[{"name":"TNO\u2014Netherlands Organization of Applied Scientific Research, NL-2595 DA, 96800 The Hague, The Netherlands"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6953-1403","authenticated-orcid":false,"given":"Rui Amaral","family":"Lopes","sequence":"additional","affiliation":[{"name":"UNINOVA\u2014Instituto Desenvolvimento de Novas Tecnologias, Faculdade De Ci\u00eancias E Tecnologia, 2829-517 Caparica, Portugal"}]},{"given":"Anabela","family":"Pronto","sequence":"additional","affiliation":[{"name":"UNINOVA\u2014Instituto Desenvolvimento de Novas Tecnologias, Faculdade De Ci\u00eancias E Tecnologia, 2829-517 Caparica, Portugal"}]},{"given":"Jo\u00e3o","family":"Martins","sequence":"additional","affiliation":[{"name":"UNINOVA\u2014Instituto Desenvolvimento de Novas Tecnologias, Faculdade De Ci\u00eancias E Tecnologia, 2829-517 Caparica, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2020,11,6]]},"reference":[{"unstructured":"Mosannenzadeh, F., and Vettorato, D.
