NG UKBP/TP 236 PDF

PURPOSE AND SCOPE

This procedure defines the key Transmission Procedure (TP) minimum requirements as applied to the delivery of Electricity Transmission single asset replacement/refurbishment/recondition investments.

Note: Key Transmission Procedures are defined as UKBP_TP106, UKBP_TP137, UKBP_TP141, UKBP_TP144, UKBP_TP163/BP221, UKBP_TP184, UKBP_TP188, UKBP_TP193, UKBP_TP211 and UKBP_TP221. All other Transmission Procedures shall fully apply if applicable to the investment.

Investments in the National Grid Electricity Transmission System that are subject to the requirements of the Network Development Process (NDP) framework shall be delivered utilising the suite of relevant Transmission Procedures (TP). (Note: UKBP_TP500 and the Network Development Process Map jointly define the Network Development Process framework).

It is recognised that for investments that fall in to the category of single asset replacement /refurbishment/recondition that are typically of a short duration then the full application of a relevant TP may not provide the most cost efficient means of delivering that investment and as such agreed key Transmission Procedure (TP) minimum requirements can be applied. These key TP minimum requirements are grouped together for each type of single asset replacement/refurbishment/ recondition investment and presented as separate appendices in this procedure. e.g. Appendix A CB Replacement (with CT’s) & (without CT’s)

Each appendix shall be approved by ETO Technical Assurance (TA), Technical Assurance Manager and ETO Engineering Project Manager.

Furthermore this procedure shall be read in conjunction with the TGN(E) 286 which defines the associated technical guidance and agreed Technical deviations to NG Technical Specifications (TS) for the delivery of Single Asset Replacement/Refurbishment/Reconditioning Investments. The technical guidance and agreed technical deviations are grouped together for each type of single asset replacement/refurbishment/ recondition investment and presented as separate appendices in TGN (E) 286. e.g. Appendix A CB Replacement (with CT’s) & (without CT’s).

Note: UKBP/TP236 Appendices and TGN(E) 286 Appendices shall correspond to each other when applied to the same type of single asset replacement/refurbishment/recondition investments.

Note: The key Transmission Procedure (TP) minimum requirements as applied to the delivery of Electricity Transmission single asset replacement/refurbishment /recondition investments SHALL NOT be utilised on any other investments without the agreement of the ETO TA Technical Assurance manager and ETO Engineering Project Manager.

The associated technical guidance and Technical Deviations (in TGN(E) 286) as applied to the delivery of Electricity Transmission single asset replacement/refurbishment /recondition investments SHALL NOT be utilised on any other investments without the agreement of ETO Asset Policy Manager.

Investments that are not defined in this procedure shall comply fully with the requirements of the UKBP/Transmission procedures where applicable.
