February 2019 Annex Meeting, Japan

December 2018, Brussels. Phase II Kick-off meeting. The overall purpose of the Kick-Off workshop was to define the scope of research and the work plan to reach the Annex Objectives, as well as confirm the participants who will contribute to the Annex.  Following presentations by the IEA and others on the work being undertaken on related topics covering valuing hydropower flexibility, a “gap analysis” was conducted to identify key research topics required to meet the Annex objectives that are not presently being covered. The workshop concluded with the development of a work plan and the participant’s contributions to the research.
