The energy transition calls for a rapid expansion of electricity grids at both transmission and distribution levels. Technological progress and digitalisation offer new solutions to system needs that can increase the efficient use of existing and new electricity grids while reducing lead times. New regulatory approaches are needed to ensure that network companies are incentivised to explore and deploy these new solutions. This Report expands on previous research conducted by the FSR on behalf of ACER and its proposal for a benefit-based scheme to promote efficiency and innovation in addressing system needs by electricity transmission system operators.
