Transmission Shortage Cost definition

Transmission Shortage Cost. As defined in the NYISO Services Tariff. Transmission System: The facilities operated by the ISO that are used to provide Transmission Services under Part 3, Part 4 or Part 5 of this Tariff. Transmission Usage Charge (“TUC”): Payments made by the Transmission Customer to cover the cost of Marginal Losses and, during periods of time when the transmission system is Constrained, the marginal cost of Congestion. The TUC is equal to the product of: (1) the LBMP at the POW minus the LBMP at the POI (in $/MWh); and (2) the scheduled or delivered Energy (in MWh). Transmission Wheeling Agreement (“TWA”): The agreements listed in Table 1A of Attachment L to the ISO OATT governing the use of specific or designated transmission facilities that are owned, controlled or operated by an entity for the transmission of Energy in interstate commerce. TWAs between Transmission Owners have been modified such that all TWAs between Transmission Owners are now MWAs.

Transmission Shortage Cost. The maximum reduction in system costs associated withresulting from an incremental relaxation of a particular Constraint that will be used in calculating LBMP. The Transmission Shortage Costs areis set at $350/MWh for relaxation above zero and less than or equal to 5MW, $1175/MWh for relaxation above 5MW and less than or equal to 20MW, and $4000/MWh for relaxation above 20MW.

  • Mr. Andy Peebles (Saracen) asked if future discussions regarding potential further enhancements to the NYISO’s transmission constraint pricing logic would include an assessment of applying the third step of the graduated Transmission Shortage Cost as a demand curve rather than a price capping mechanism.

  • The NYISO is proposing the following two changes to its current transmission constraint pricing implementation:• Apply the graduated Transmission Shortage Cost method to all transmission constraints with a non-zero constraint reliability margin (CRM)• Change the second step of the graduated Transmission Shortage Cost from $2,350/MWh to $1,175/MWhThe Analysis presented the consumer cost impact of the current implementation compared to the proposed implementation.

  • Improving the accuracy of the Transmission Shortage Cost will cause the NYISO markets to take more efficient dispatch and commitment actions, and set more efficient prices.
