The work of the Consultation Forum Phase II was performed from mid-October 2017 until the end of July 2019 through the organisation of four plenary conferences, six coordination meetings with team leaders and moderators of the EU Member States as well as other ad-hoc experts meetings and the completion of deliverables as forecasted in the Grant Agreement. Topics covered throughout the CF SEDSS II include but are not limited to energy management, energy efficiency, renewable energy sources (RES), protection of critical energy infrastructures (PCEI) and financial considerations. Among these topics, the contributions in energy management and energy efficiency including policies, strategies, processes, roadmaps, methodologies and tools to improve energy performance constitute the framework for implementation of RES and PCEI. On the basis of such topics, reference material was generated throughout the 22-month duration of CF SEDSS II, ranging from the global strategic context for energy as well as the defence context for energy, the purpose and scope of EU energy legislation, and a selection of available delivery tools and techniques. Overall, the implementation of CF SEDSS II enabled the Agency to efficiently disseminate and communicate the project’s results to the interested bodies and practitioners to maximise their exploitation. Moreover, the Agency provided the targeted audience with the appropriate platform for sharing knowledge, expertise and good practices in energy management including energy efficiency, renewable energy sources as well as defence-related critical energy infrastructures. The outcome of the above-coordinated activities also contributed to further build a collective consciousness among the EU MoDs regarding the importance of promoting defence adaptation to a cleaner, safer, and more affordable energy model. In addition to other deliverables and dissemination/exploitation reports, the project also produced: ‘Guidance Document: CF SEDSS II Results and Recommendations for Sustainable Energy in the Defence and Security Sector’; ‘Lessons Learned From the Organisation of the Second Phase of the Consultation Forum for Sustainable Energy in the Defence and Security Sector and Recommendations’; and Eighteen ‘Information Sheets’, which provide an overview of the defence energy-related project ideas.
