Frequency Control Service Sample Clauses

Frequency Control Service. Frequency Control Service is necessary to provide for the continuous balancing of resources (generation and interchange) with load and for maintaining system frequency at sixty cycles per second (60 Hz). Frequency Control Service is accomplished by committing on-line generation whose output is raised or lowered (predominantly through the use of automatic generation control equipment, the load-frequency control) and by other non-generation resources capable of providing this service to follow the moment-by-moment changes in load. The obligation to maintain this balance between resources and load lies with the Transmission Provider. The Transmission Provider shall offer this service when the Transmission Service is used to serve load within its Control Area. The Transmission Customer shall either purchase this service from the Transmission Provider or make alternative comparable arrangements to satisfy its Frequency Control Service obligation. To the extent the Control Area operator performs this service for the Transmission Provider, charges to the Transmission Customer are to reflect only a pass-through of the costs charged to the Transmission Provider by the Control Area operator. Generator Imbalance Service is provided when the output of a generating unit synchronized to the Transmission Provider’s system does not match the output that unit is scheduled to supply to (1) another Control Area or (2) a load in the Transmission Provider’s Control Area in a given hour. The Transmission Provider is required to offer Generator Imbalance Service insofar as it is able to do so using its resources or those made available to it if the Transmission Service is used to deliver energy from a generating unit synchronized to its Transmission System. The Transmission Customer must either purchase this service from the Transmission Provider or make comparable alternative arrangements, which may include using non-generation resources able to ensure this service, in order to fulfill its obligation to provide Generator Imbalance Service. The Transmission Provider may impose a penalty on the Transmission Customer for generator imbalances under this Schedule or for energy imbalances under Schedule 5 if either occurs during the same hour, but not for both, except if imbalances have a combined aggravating rather than offsetting effect. Generator Imbalance Service is charged based on the following deviation bandwidths: (i) charge for ±1.5% deviation (minimum of 2 MW) from the sche...
