The energy ecosystem is undergoing a rapid transition towards a more sustainable future, driven by increasing renewable energy sources, distributed generation, and energy storage. This is leading to a redefinition of roles and accountability within the energy value chain, with the traditional role of the Transmission System Operator (TSO) becoming more relevant than ever. However, the increasing share of intermittent generation sources is also fundamentally reshaping the future of the energy industry, with new stakeholders, higher stress on the energy grid, digitalization, intermittence, and flexibility as key drivers. The traditional linear grid structure is evolving towards a meshed structure, and both TSOs and DSOs are being forced to rethink their traditional business models. This is leading to a whole range of emerging "energy solutions" along the value chain, and the need for energy industry participants to adapt to this changing landscape.
