Transmission System Operator (TSO)
Definition
The entity responsible for operating a high-voltage electricity transmission network in a given country or region. TSOs log grid frequency in real time and are the primary custodians of reference data for ENF forensic analysis. Examples include National Grid ESO (UK), ENTSO-E members (EU), and the regional interconnections in the US.
