PM0103: National Grid Legal Separation - consequential changes to STCPs to reference NGESO and SO/TO interface design changes to STCPs

This proposal seeks to modify the System Operator Transmission Owner Code Procedures (STCPs) to reflect the creation of a new National Grid Electricity System Operator (NGESO) that is legally separated from National Grid Electricity Transmission Limited.  References to NGET have been replaced by NGESO, where relevant, throughout the STCPs in order to ensure the System Operator and Transmission Owner obligations are clear, and and regional differences in Scotland and England and Wales have been reflected.
