Common use of Imbalances Within Deviation Band 3 Clause in Contracts

Imbalances Within Deviation Band 3. Deviation Band 3 applies to the portion of the deviation (i) greater than ± 7.5 percent of the scheduled amount of energy, or (ii) greater than ± 10 MW of the scheduled amount of energy, whichever is larger in absolute value. (1) When energy delivered in a schedule period from the generation resource is less than the energy scheduled, the charge is 125 percent of BPA’s highest incremental cost that occurs during that day. The highest daily incremental cost shall be determined separately for HLH and LLH. (2) When energy delivered in a schedule period from the generation resource is greater than the scheduled amount, the credit is 75 percent of BPA’s lowest incremental cost that occurs during that day. The lowest daily incremental cost shall be determined separately for HLH and LLH.
