SCHEDULE VRC
VARIABLE RATE GENERAL SERVICE
SCHEDULE VRCis an optional rate schedule for high demand general service provided to customers eligible to be served under Schedule HDC. A customer that chooses this rate schedule may not return to a standard rate schedule for a period of 1 year after electing this schedule, provided that, should a new rate ordinance which changes Schedule VRC be adopted during this time, the customer may request return to a standard rate schedule on the effective date of the new ordinance.

At the time a customer elects to take service under Schedule VRC, the customer must choose whether to pay an energy charge as defined in Option 1 -- DJ-COB or Option 2 -- DJ Mid-Columbia. After choosing an energy charge option, a customer may not choose a different energy charge option for a period of 1 year except that, should a new rate ordinance which changes Schedule VRC be adopted during this time, the customer may request a change in energy charge option upon the effective date of the new ordinance or may request return to a standard rate schedule upon the effective date of the new ordinance.

Energy Charge:
Option 1 -- DJ-COB (DJ-COB price in ¢/kWh - 0.07¢/kWh) x 1.1562 + 0.15¢/kWh

The DJ-COB (Dow Jones-California Oregon Border) price is the appropriate peak or off-peak DJ-COB firm price converted to cents per kWh for the day and time period of the consumption. Peak and off-peak periods will be as defined by the DJ-COB price rather than as defined in the Demand Charges section of Schedule VRC or elsewhere in the ordinance codified in this section. In the case that a price is not available for a given day, the average of the preceding and following days' prices will be used. Peak and off-peak prices will be calculated separately via this method.

Option 2 -- DJ Mid-Columbia (DJ-Mid-Columbia Price in ¢/kWh) x 1.1562 + 0.15¢/kWh

The DJ Mid-Columbia (Dow Jones Mid-Columbia) price is the appropriate firm peak or off-peak DJ Mid-Columbia price index converted to cents per kWh for the day and time period of the consumption. Peak and off-peak periods will be as defined by the DJ Mid-Columbia price index rather than as defined in the Demand Charges section of Schedule VRC or elsewhere in this ordinance. In the case that a price is not available for a given day, the average of the preceding and following days' prices will be used. Peak and off-peak prices will be calculated separately via this method.

Retail Services Charge: 1.46¢ per kWh
DEMAND CHARGES:
Peak:
All kW of maximum demand between 6 am and 10 pm, Monday through Saturday, excluding major holidays*, at $0.40 per kWh
