The "Curtailment: GSP" dataset details the total measured curtailment aggregated at a GSP level for the last 4 years.At this time only curtailment events measured and recorded by our Active Network Management (ANM) system is captured.It should be noted that this dataset does not align with the Curtailment Limit as described under Ofgem’s Access Significant Code Review (SCR) as it includes both curtailment under fault conditions and curtailment driven by Transmission network constraints. Curtailment as per the Access SCR will not be measured until after the 1st April 2023 and is contingent on customers signing onto Curtailable Connection Agreements.This dataset is updated on a monthly basis.DefinitionsNameDescriptionUnit of MeasurementGSPGrid Supply Point.N/AAggregated Rated Capacity of ANM SitesTotal capacity connected under ANM connections per annum.

Please note this is an assumed value based on network measurements before and after curtailment.Mega Watt Hours (MWh)Some values are left blank in the dataset given that from February 2021 a number of customers connected under the Dunbar ANM system moved to an unconstrained connection and therefore no data is published beyond that point.
