1 Statement of Woks Data Template Vesion: 4.0 Date: This Statement of Woks (SoW) Data Template is to be completed by Distibution Netwok Opeatos (DNOs) in ode to povide National Gid the equied data fo SoW applications. Thee ae two types of SoW applications; an initial SoW baseline assessment and a SoW update. The baseline assessment is fo the fist SoW application of the GSP(s) within the new SoW pocess and the SoW update is fo when the mateiality tigge has been beached and a netwok e-assessment is equied. The baseline assessment has moe extensive data equiements as it is the fist time the detailed netwok data is being povided. In the SoW updates a educed set of data can be supplied as data is only equied whee thee have been changes fom the baseline assessment. A summay of the data equiements is outlined in the table below SoW Application Data Requiements Data Schedule Embedded Powe Station Data Fault Infeed Data Demand Data Netwok Data Medium Powe Station Data SoW Baseline Assement Full submission of all data Full submission of all data Full submission of all data Full submission of all data Full submission of all data SoW Update Only changes to Embedded Powe Stations Only the contacted Embedded Powe Station fault infeed. Updated annually o post season Only when equied fo new connections Only equied fo new connections Please note that the Statement of Woks pocess being eviewed within the ENA howeve it is envisaged that this dataset will emain unchanged following this eview.

Gid Code Link to Data Requiements NG equies the infomation within this data template to detemine the impact on the NETS. Fo example, a 33 kv PV fam will impact the PQ chaacteistics at the BSP.

2 Gid Code Link to Data Requiements NG equies the infomation within this data template to detemine the impact on the NETS. Fo example, a 33 kv PV fam will impact the PQ chaacteistics at the BSP. NG does not model below the BSP level theefoe this infomation needs to be povided by the DNO. Voltage studies ae dependent on eactive powe flows, thus without this infomation an accuate voltage study cannot be undetaken. This equiement is futhe claified within Planning Code Appendix A2 (of the Gid Code) Standad Planning data, Use s System Data (see below). In essence, the infomation equest above is aleady codified. PCA.6 povides a list of possible tigges fo equiing infomation as pe PC.A Whee existing data povision is insufficient fo the pupose of poducing meaningful system studies, NGET may easonably equest such data

The name and efeence numbe must be the same as in the Appendix G within the BCA. * Any Small Powe Station that connects above the level of the lowest voltage modelled node (BSP) will be discetely modelled and will equie: - the thee phase shot cicuit contibution (oange columns above) - its location maked on the week 24 single line diagam (see Netwok Data tab) - netwok data fo the netwok between its connection point and the netwok povided in the Week 24 SLD (see Netwok Data tab)

This is valuable fo confimation of P,Q because it is ecognised that data povided within Week 24 submission is fo the pupose of Demand Compliance and not necessaily fo undestanding the wost case high volts o peak evese flows * Node Names should align with those within Week 24 submission (and associated SLDs) * Whee thee is a new Node o any netwok einfocement on the DNO netwok this must be clealy identified and elevant paametes povided to NGET (see the 'Netwok Data' tab) * Demand should be based on the most ecently meteed demand of the elavent peiod on yea and should be updated annually (e.g. following the maintenance peiod, the 'Maintenance Peiod Peak Demand' can be updated) * If thee ae significant inceases of mico-geneation/stoage within a yea (equal o geate than Mateiality Tigge size fo the GSP) this should be discussed with NGET pio to SoW updates * Whee thee ae planned futue demand connections o significant load change in the next 7 yeas which will have a mateial impact on the demand as seen at the GSP this should be detailed in the comments below.

6 Additional Netwok Data REQUIRED IN SOW UPDATE FOR NEW MEDIUM POWER STATIONS OR DISCRETELY MODELLED SMALL POWER STATIONS * Netwok data will be equied upto the voltage below the GSP/subtansmission level voltage. * Fo example fo a GSP connected at a subtansmission voltage of 132kV the next voltage down may be 33kV. All node and banch data will be equied up until this voltage. * The demand and geneation data (on the othe tabs in this wokbook ) should be supplied fo the nodes at lowest voltage level modelled * The fomat of the node and banch data should be the same as the shedule 5 data which foms pat of the week 24 data submsisions, please update the elavent week24 shedules when poviding this data * The data equiements below ae explained in moe detail in the Statement of Woks Data Guidance Note Data Item Gid Code Section DRC Shedule Desciption
