Boundaries - GB DNO Licence Areas

This dataset contains approximate GIS (geographic information system) geospatial boundaries for each of the DNO Licence Areas in Great Britain. There are 14 licensed Distribution Network Operators (DNOs) in Britain and each is responsible for a regional distribution services area. DNO Licence Areas are sometimes referred to as GSP Groups and historically have also been known as Public Electricity Supplier (PES) regions, though the latter name is no longer widely used.

The DNO Licence Area boundaries are unusual because they are only well defined when tested. The boundaries tend to run through rural areas and change over time whenever a new connection is added close to a boundary. For example, a new connection close to an existing boundary can approach the DNO responsible for both neighbouring Licence Areas to ask for a connection, and is free to choose either depending on how much they will charge - once the new connection is made the boundary is, theoretically, re-drawn to ensure that the new connection falls into the correct Licence Area. The boundaries in this dataset were originally shared by Western Power Distribution, now National Grid Electricity Distribution (the DNO responsible for 4 of the 14 Licence Areas) and come with the disclaimer that they are probably a little outdated and not 100% accurate. That said, they are a good indication of the geography of DNO Licence Areas.

DNO Licence Areas are widely used as an aggregation entity when reporting electricity network data, for example, in Elexon's publication of electricity settlement data. As such, they are also useful for regional modelling of the GB electricity transmission network, for example to aggregate distributed embedded generator energy flows onto the transmission network. A good example of this is the Regional PV_Live outturn estimates published by The University of Sheffield (https://www.solar.sheffield.ac.uk/pvlive/regional/).Note: DNO Regions do not align with standard geographic regions and should not be used for mapping beyond that related to DNO and Power Networks.

本数据集包含英国境内各配电网络运营商（Distribution Network Operator, DNO）许可区域的近似地理信息系统（Geographic Information System, GIS）空间边界。英国现有14家持证配电网络运营商（DNO），每家负责一片区域配电服务范围。DNO许可区域有时也被称为GSP群组，历史上也曾被称作公共电力供应商（Public Electricity Supplier, PES）区域，但该名称现已较少使用。

DNO许可区域的边界较为特殊，仅在经过核验时才能得到明确界定。此类边界通常穿行于乡村区域，且每当边界附近新增并网项目时，边界便会随时间发生调整。举例而言，若某并网项目紧邻现有边界，其申请方可向负责相邻两个许可区域的两家DNO提出并网申请，并可根据双方收费标准自由选择接入方；并网完成后，理论上需重新划定边界，以确保该新项目归属至正确的许可区域内。本数据集内的边界数据最初由Western Power Distribution（现更名为National Grid Electricity Distribution，即负责14个许可区域中4个的DNO）共享，且附带免责声明：此类数据或存在一定过时性，并非100%准确。尽管如此，该数据集仍能较好地反映DNO许可区域的地理分布情况。

DNO许可区域常被用作电力网络数据上报时的聚合单元，例如Elexon发布的电力结算数据即采用该划分方式。因此，该划分方式也可用于英国电力传输网络的区域建模，例如将分布式嵌入式发电机的能源流量聚合至传输网络中。谢菲尔德大学发布的《区域PV_Live实际发电量估算报告》（https://www.solar.sheffield.ac.uk/pvlive/regional/）便是此类应用的典型案例。

注意：DNO区域与标准地理区域并不匹配，仅可用于与DNO及电力网络相关的绘图场景，不得挪作他用。
