Improvements to Electricity Information Exchange Protocol (EIEP) fields

We're proposing to increase:

• the interruption reason field in EIEP5A from 50 characters to 255 characters
• the unique request identifier field from 15 characters to 36 characters.

We regularly consult with affected participants on changes to Electricity Information Exchange Protocols (EIEPs), generally with more than one change required at a time.

We sought industry and stakeholder feedback on the change to EIEP5A as a priority as there was a corresponding piece of work in progress to determine if we were to mandate a delivery mechanism for EIEP5A.

We also consulted on a change to EIEP13A, EIEP13B and EIEP13C as there is demand for updating the formats to allow for the use of UUID v4. 

We're proceeding with the proposals unchanged. They were fully supported by all submitters.
