IN Brief:
- EnBW and EWE have developed a concept for Flexible Connection Agreements as a temporary measure for overloaded grid assets.
- The proposal is designed to keep renewable projects moving while maintaining grid stability and providing a standardised contract structure.
- The plan comes as Germany wrestles with grid bottlenecks, decentralised generation growth, and wider reform of connection rules.
EnBW and EWE have set out a joint concept for Flexible Connection Agreements, proposing a standardised contract model that would allow generators to connect under managed constraints where parts of the grid are overloaded. The proposal is intended as a temporary operating tool rather than an alternative to network reinforcement, giving projects a defined route forward while bottlenecks are addressed and grid stability is maintained.
The model is aimed at a problem that has become increasingly familiar across European power systems. Renewable generation is being developed faster than parts of the network can be expanded, leaving projects ready to connect into lines, transformers, or substations that do not yet have the capacity for a full and unconditional access arrangement. Under a flexible contract, a plant could connect on terms that recognise those limits from the start, rather than waiting until reinforcement has removed them entirely.
EnBW and EWE are also using the proposal to shape the wider debate on German grid policy. Both companies support closer alignment between renewable rollout and grid development, but they have criticised an alternative redispatch reservation model that could allow operators to restrict renewable connections in congested areas while developers temporarily waive compensation rights linked to curtailment.
The operating conditions in northern Germany show why the issue has become more pressing. EWE NETZ manages around 80,000km of electricity grid and handles roughly 11TWh of renewable feed-in each year, equivalent to 108% of electricity consumption across its service area. More than 100,000 decentralised generation plants, with total connected output above 7,400MW, are already tied into that network, alongside growing loads from electrified heating and transport.
Flexible contracts reflect a shift toward more actively managed networks. As generation and demand become more variable and decentralised, connection terms are beginning to mirror those conditions. Standardised agreements reduce negotiation time and create a clearer basis for allocating operational limits, compensation, and upgrade timelines. In a system built around increasing volumes of distributed renewable generation, managed access is moving closer to the centre of grid operations.
