For SCE and SDG&E, the deadband will be considered exceeded when there is a decline of at least 7.5 percent in the number of top 100 high-cost hours that fall within the summer peak and mid-peak period. The definition of Base TOU period remains unchanged as defined in Decision D.17-01-006 and any changes to the definition is beyond the scope of this resolution. A workshop to further consider deadband tolerance methodological issues would be of limited value, and would compete with higher-priority needs. Therefore, it is Ordered: PG&E AL 5037-E is approved with the following modifications: PG&E shall use a 5 percent differential as a trigger; PG&E shall not use marginal transmission costs for its current deadband analyses. Transmission and distribution marginal costs shall be included in the future calculation of the deadband analysis if used by the Commission to determine TOU periods. SCE AL 3581-E is approved with the following modifications: SCE shall use the top high-cost 100-hour criterion only; SCE shall use a 7.5 percent differential as a trigger; the deadband will be considered exceeded when there is a decline of at least 7.5 percent in the number of top 100 high-cost hours that fall within the summer peak and mid-peak period, or a decline of at least 7.5 percent in the number of top 100 low-cost hours that fall within the winter super-off-peak period. Transmission and distribution marginal costs shall be included in the calculation of the deadband analysis if used by the Commission to determine TOU periods. SDG&E AL 3064-E is approved with the following modifications:
