eNAMS

eNAMS (electricity Network Access Management System) is an NGESO developed tool created to effectively manage asset owners’ electricity system outage requests and to give visibility of those outages to affected users.

It replaces the Outage Management capability within TOGA (Transmission Outage & Generator Availability) and enables:

  • Requesting and approving of system outages
  • Commissioning and decommissioning of assets
  • Management of OCLRs (Operation Capability Limitation Records)
  • Performance reporting
