Summary
Tomorrow’s carbon neutral world will be based on electrification and carbon-free electricity supply. Especially in Japan and France, that electricity would be generated by both nuclear and renewable energy. To integrate all renewable energy capacities, such as photovoltaics (PV) and wind power, into the grid in line with each country's goals, there are big challenges such as grid congestion. While the congestion only starts to appear in both countries, new infrastructure will need to be built in the future to prevent future congestion especially in local grids. It is costly and time-consuming, and may also increase the cost to society. Thus, both countries developed solutions—Japan’s Connect & Manage System and France’s New Adaptative Zonal Automaton

Future measures towards big challenges, for NEDO Connect & Manage 2.0, include grid-scale storage systems to balance supply and demand, and prevent congestion. The congestion management functionality was already integrated and tested within NAZA during the Ringo experimentation.
Japan’s NEDO Connect & Manage 2.0 and France’s Ringo project explore the potential and challenges of utilizing these flexibilities. This paper introduces these initiatives, provides results of technical and economical verification, and presents an initiative for storage systems location guidance and early connection. These initiatives provide insights to reduce curtailment and achieve cost savings through optimization of existing and future physical infrastructure.
