One possible answer lies in Flexible Connection Agreements (FCAs). These agreements enable existing grid capacity to be used more efficiently and allow additional grid connections to be realized even before the completion of necessary grid reinforcement measures. This makes it possible to implement projects earlier without compromising security of supply.

On this topic, our colleagues Dr. Henning Schuster, Dr. Philipp Heuser, and Kilian Bienert have published a technical article in the latest issue of ew Magazine. The article explains the fundamentals of Flexible Connection Agreements, presents different technical approaches, and examines the requirements and perspectives of network operators, investors, and project developers.

From Static to Dynamic FCA Models

Flexible grid connections are not a one-size-fits-all solution. Depending on the application, they can be designed in different ways. The article outlines several stages in the evolution of FCAs, ranging from simple static capacity limits and rule-based approaches to dynamic and curative models. The common objective is to unlock additional connection capacity while maintaining secure grid operation.

Rule-based FCAs, in particular, are currently at the center of many implementation efforts. In these models, potential restrictions are linked, for example, to the forecasted generation from wind and photovoltaic plants. This allows existing grid capacity to be utilized more effectively and creates additional connection opportunities. Many of the solutions currently being developed for battery storage systems, data centers, and electrolyzers follow this approach.

FCAs as a Complement to Grid Expansion

The authors emphasize that Flexible Connection Agreements cannot replace grid expansion. However, they can help bridge the period until new grid infrastructure is completed and enable more efficient use of existing capacity. Their success depends on transparent, non-discriminatory, and voluntary agreements that create clear benefits for connection customers.

In addition, the interaction between FCAs, grid expansion, network planning, allocation procedures, and congestion management is becoming increasingly important. In the long term, an integrated target model is emerging in which these instruments are closely interconnected and jointly contribute to meeting the growing demand for grid connections.
