Available Transmission Capability definition

Available Transmission Capability or ‘ATC’ means the transfer capability, in MW, of the inter-control area transmission system available for scheduling cross-border transactions (through long-term access, medium-term open access and short-term open access) in a specific direction, taking into account the network security. Mathematically ATC is the Total Transfer Capability less Transmission Reliability Margin

Related to Available Transmission Capability

  • Transmission Facility means a facility for transmitting electricity, and includes any structures, equipment or other facilities used for that purpose as defined in the Parties respective XXXXx.

  • Transmission Reliability Margin or “TRM” shall mean the amount of transmission transfer capability necessary to provide reasonable assurance that the interconnected transmission network will be secure. TRM accounts for the inherent uncertainty in system conditions and the need for operating flexibility to ensure reliable system operation as system conditions change.
