The provided sources discuss two pivotal EU regulatory initiatives concerning electricity grids: the forthcoming Network Code on Demand Response (NC DR) and the already implemented Regulation on Requirements for Generators (RfG). The NC DR aims to integrate demand-side flexibility from consumers and distributed resources into energy markets, standardising processes and promoting competition to enhance grid stability and reduce infrastructure costs. Conversely, the RfG establishes harmonised technical requirements for power generators connecting to the grid, ensuring new renewable and conventional facilities contribute to grid stability and reliability through capabilities like frequency and voltage support. Both regulations critically impact Energinet, Denmark’s Transmission System Operator, by necessitating digital transformation, IT infrastructure upgrades, and evolving operational procedures to manage a highly flexible, decarbonised, and interconnected European power system. These initiatives, while distinct, collectively aim to create a more resilient, efficient, and market-driven energy landscape, aligning with Energinet’s strategic goals for automation, data-driven operations, and renewable energy integration.
