Here you will find the electrical standards documents including specifications for electronic data communications facilities that apply to transmission-connected generators in England, Wales, and Scotland.
Please use the table below to see which standards apply to your connection.
RES | SPT | SHE Transmission | EDL/EDT | Control Telephony | |
Directly connected in England & Wales | ✔ | ✔ | ✔ | ||
Directly connected in SPT’s area | ✔ | ✔ | ✔ | ||
Directly connected in SHE Transmission’s area | ✔ | ✔ | ✔ | ||
Embedded BM Participant | ✔ | ✔ |
RES = Relevant Electrical Standards
SPT = Scottish Power Transmission
SHE = Scottish Hydro Electric Transmission
EDL = Electronic Dispatch Logging
EDT = Electronic Data Transfer
Raising a change and further help
The process for raising changes to the electrical standards is in paragraph 11 of the general conditions of the Grid Code. If you are interested in raising a change to the electrical standards, please contact the Grid Code Review Panel Secretary in the first instance at [email protected].
You can find further details in the RES Guidance Document.
If you need access to the GB Transmission System National Grid Technical Specifications, please contact the team at [email protected].
England and Wales electrical standards
Please note that the titles and any references within these standards may use or omit leading zeroes interchangeably for ease of sorting. So for example, TS2.01 and TS2.1 refer to the same document.
