NDP SPM Primary Group Polygons

The geographic areas supplied by the primary substations and the grid supply points (GSPs) in SPD, and the primary substations, grid groups and GSPs in SPM.  For additional information on column definitions, please click on the Dataset schema link below.Disclaimer: The boundaries change periodically as our network evolves, e.g. if we add a new primary substation or interconnect primary substations.  These are the polygons that reflect the network at the time the DFES is published; other publications have their own sets of polygons where applicable.  Download dataset metadata (JSON)If you wish to provide feedback at a dataset or row level, please click on the “Feedback” tab above.To view this data please register and login.

本数据集涵盖了由主变电站和电网供应点（GSPs）在SPD中提供的地理区域，以及SPM中的主变电站、电网组和GSPs。有关列定义的详细信息，请点击下方的“数据集架构”链接。免责声明：随着网络的演变，边界会定期发生变化，例如，若新增主变电站或连接主变电站，则边界将随之调整。此处所列的多边形反映了DFES发布时的网络状态；其他出版物将根据适用情况提供各自的多边形集。请下载数据集元数据（JSON）。若希望在数据集或行级别提供反馈，请点击上方的“反馈”标签。为查看此数据，请注册并登录。
