We are supporting the issuing of Flexible and Curtailable Connections by providing curtailment estimates and the input data required for stakeholders to further understand the volume, shape and causes of curtailment driven by Active Network Management.
For applications that meet the requirements of DCUSA Schedule 2D a Curtailment Limit will be provided in line with the methodology.
Where a new connection has been identified as needing to be controlled using an Active Network Management system, which does not qualify as a Curtailable Connection, an estimate of the curtailment caused by this system will be provided .
Explore the estimated level of curtailment for a distributed energy resources such as wind, solar PV or battery storage due to constraints managed by NGED.
This tool specifically focuses on the anticipated curtailment a scheme may be subject to due to Active Network Management (ANM) and its dependency on the queue ahead in the Last In First Out (LIFO) stack.
For more detail on how the analysis is carried out please see the curtailment estimator methodology document.
We provide the following datasets to help with curtailment analysis prior to submitting an application or carrying out further analysis having received a curtailment estimate. Our recommendations on how this data should be interpreted are detailed within the NGED DSO Curtailment Analysis Data Usage Guidance document .
