The accelerated expansion of renewable energy is creating challenges for German distribution system operators: grid connection requests exceed available grid capacity. Flexible Connection Agreements (FCAs) offer a pragmatic solution by allowing new generation assets, storage systems, and consumers to connect under defined conditions, without requiring immediate, costly, and time-intensive grid expansion measures.
Until now, however, a transparent and data-driven methodology for calculating FCA limits has been missing. Discussions often remained at a regulatory level, without providing grid operators with a practical, operational tool.
Data-driven methodology instead of generic assumptions
P3 energy solutions, in collaboration with Bayernwerk Netz, has developed an innovative, data-based methodology that addresses this gap. FCA limits are calculated using real grid utilization data combined with statistical methods, rather than conservative assumptions or standardized rules.
The methodology differentiates between two scenarios:
For generation assets such as wind or solar plants, a flexible calculation approach is applied, reflecting the fact that potential feed-in peaks can be managed through redispatch measures. Consumer installations, which cannot be directly controlled by the grid operator, are assessed using a more conservative calculation approach.
A key advantage is the explicit consideration of seasonal differences in grid utilization. This enables a much more realistic representation of actual grid operating conditions.
Increased connection capacity with full grid security
For grid operators, the methodology enables faster approval processes, reduced congestion, and reduced or avoided grid expansion investments. Asset operators benefit from increased operational flexibility and improved economic predictability of their projects.
FCA-based connections allow more than 25 % additional energy feed-in for generation assets and over 60 % higher energy delivery for consumer installations compared to conventional connection approaches—while fully maintaining grid security.
A scalable tool for the energy transition
P3 energy solutions provides the methodology as an automated analysis procedure that network operators can use directly in their own software environment. The FCA limits are calculated in a reproducible, transparent and scalable manner based on the respective grid utilisation data. Further information will follow shortly in a white paper, or speak directly to the P3 experts at stand 5H102 at E-World.
Future developments will further enhance the methodology by improving support for hybrid assets such as battery storage systems and enabling automated optimization of key calculation parameters. This positions the approach as a robust planning and operational tool for distribution system operators.
