The CNC define uniform technical requirements for grid connection of generation plants, demand facilities and HVDC systems as well as their capabilities to support the system. These requirements are critical for the efficient grid integration of emerging technologies such as battery storage, electric vehicles, electrolysers and heat pumps. Without established technical specifications, the risk of critical grid situations, including blackouts, will only increase.
In particular, the absence of European regulation leaves the industry without harmonised rules for grid forming capabilities for converter-based resources. As renewable energy technologies, mostly converter-based, are set to take over the capabilities of conventional power plants, grid-forming requirements are essential. Any delays in the adoption process jeopardizes system stability of the European electricity supply and hinder investment.
VDE FNN emphasizes that system stability cannot be achieved at the national level alone, but requires a concerted effort from all Member States. Only the swift adoption of CNC 2.0 will ensure a secure European electricity supply, fair market conditions, and the successful transformation of the energy system.
To this end, VDE FNN has published the Position Paper "Delay in the adoption of the Connection Network Codes jeopardises system stability" to urge the European Commission to resume the adoption process as soon as possible.
