In this discussion paper, developed by RGI in close collaboration with its transmission system operators (TSOs) and NGO members, we focused on flexibility and the large variety of flexibility options that will be necessary while we decarbonise. 

As the name suggests, a discussion paper is an ongoing work and not a final one, which tries through incremental steps to find a common understanding and shared terminology and to represents different needs and approaches to flexibility. Most importantly, it also addresses the challenges of the technical complexity of flexibility. It is a first step to bring some clarity and will need to be complemented by further discussions with RGI Members and all relevant actors. In this phase of the energy transition we have to constantly learn from each other in order to find  solutions.
