Chair and Vice Chairs must represent parties having a different role in the energy system,  hence representing potentially different points of view.  Permanent Working Groups and  Ad-Hoc Task Forces are created by the Governing  Board. A Working Group and/or Ad-Hoc Task Force is composed of a limited number of  high-level experts willing to voluntarily participate to the work of the ETIP and act in their  personal capacity. Currently there are five permanent working groups with approximately 200  members altogether. Working group members are stakeholders from industry, research,  consumer organisations and academia. Membership, election and the renewal processes are  described in the document Renewal Procedures for Working Group Chairs and Co-chairs,  Dismissal of Working Group Members.$^{5}$  Finally, there is a  National Stakeholder Coordination Group (NSCG)  with members from  the participating countries that provides a sounding board and exchange platform for national  R&I stakeholders in the area of energy systems and networks. BRIDGE is the cooperation group of ongoing smart grids and energy storage projects funded  by the European Horizon 2020 programme under Societal Challenges – Secure, clean and  efficient energy. It is a European Commission and INEA initiative uniting these projects to  create a structured view of cross-cutting issues, which are encountered in the demonstration  projects and may constitute an obstacle to innovation. The projects currently involved in  BRIDGE are listed on the BRIDGE website.$^{6}$ They are mainly Innovation Actions.  BRIDGE fosters continuous knowledge sharing among projects. This should allow them to  synthesize conclusions and recommendations for efficient exploitation of the project results in  specific areas. The projects established four different working groups: data management,  business models, regulations and customer engagement. In future, the working groups may be  restructured and tenderers should tailor their offers to accommodate five working groups. The  working groups contribute to ad-hoc task forces on emerging politically-relevant topics.  In the coming years, BRIDGE will also have to manage the knowledge that has been  generated by the working groups, taskforces and by ongoing and finished projects and ensure  it remains available and easily accessible. This implies measures to actively involve  stakeholders that participated in the past.  $^{5}$ https://www.etip-snet.eu/wp-content/uploads/2017/03/2017052614019.-ETIP-SNET-WGs-membership-and- rotation-rules-proposal.pdf  $^{6}$ BRIDGE Horizon 2020, https://www.h2020-bridge.eu/  8 1.4.1.3.
