RULE §25.381Capacity Auctions

          (-b-) The excess fuel price is the product of a heat rate equal to 10.850 MMBtu per MWh times the daily gas price.

    (G) Timing of payment of contract price. The entitlement holder shall pay the affiliated PGC the capacity payment portion of the contract price not less than five days before the beginning of the entitlement month or 20 days after receiving an invoice for the capacity payment from the affiliated PGC, whichever is later. The entitlement holder shall pay the remainder of the contract price after receiving an invoice for that amount in accordance with the terms of the Agreement. If the affiliated PGC owes the entitlement holder any net amount under the contract price calculation, it will pay that amount to the entitlement holder in accordance with the terms of the Agreement.

  (4) Gas-cyclic product.

    (A) Description. The gas-cyclic entitlement shall be flexible day-ahead shaped power.

    (B) Block size. Each gas-cyclic capacity entitlement shall be 25 MW in size.

    (C) Fuel price.

      (i) Except as specified otherwise in clause (ii) of this subparagraph, the fuel price owed to the affiliated PGC by the capacity entitlement holder for gas-cyclic capacity dispatched will be 12.100 MMBtu per MWh times the MWh of the gas-cyclic power dispatched under the entitlement times the daily gas price.

      (ii) EGSI.

        (I) For EGSI gas-cyclic capacity in the eastern congestion zone, the fuel cost owed to its affiliated PGC by the capacity entitlement holder for the gas-cyclic capacity dispatched will be 12.100 MMBtu per MWh times the MWh of gas- cyclic power dispatched under the entitlement times the Henry Hub daily gas price.

        (II) For EGSI gas-cyclic capacity in the western congestion zone, the fuel cost owed to its affiliated PGC by the capacity entitlement holder for the gas-cyclic capacity dispatched will be 12.100 MMBtu per MWh times the MWh of gas- cyclic power dispatched under the entitlement times the average of the Henry Hub daily gas price and the Houston Ship Channel daily gas price.

    (D) Starts per month and associated costs. The entitlement holder of gas-cyclic capacity shall be entitled to direct the selling affiliated PGC to make up to the amount of starts per month of each entitlement of gas-cyclic capacity allowed pursuant to subparagraph (E)(v) of this paragraph.

    (E) Gas-cyclic scheduling.

      (i) Schedule types. The entitlement holder shall submit a day-ahead schedule for the entitlement.

      (ii) Timing of scheduling.

        (I) The entitlement holder shall submit day-ahead schedules for the entitlement to seller no later than 8:00 a.m. The daily capacity commitment is determined for a gas-cyclic entitlement by the 8:00 a.m. schedule, unless the entitlement holder notifies seller, in the schedule, that it is exercising its option to set the daily capacity commitment in the last schedule submitted before the gas-cyclic start deadline pursuant to subclause (IV) of this clause.

        (II) The entitlement holder may submit to seller a revised day- ahead schedule for energy from the entitlement no later than noon, subject to the limit on maximum energy in clause (iv)(II) of this subparagraph.

        (III) No hour-ahead schedules are permitted for energy from gas- cyclic entitlements.

        (IV) The gas-cyclic start deadline for declaring the daily capacity commitment for each settlement interval in an operating hour is 15 hours before the start of the operating hour.

      (iii) Schedule content. Each schedule shall specify, for each scheduling interval, the energy scheduled to be delivered to the entitlement holder from the entitlement.

      (iv) Scheduling limits.

        (I) Minimum energy. The entitlement holder may not schedule energy at any level between zero MW and five MW from the entitlement at any time during the month.

        (II) Maximum energy. The entitlement holder may not schedule energy at any level greater than the daily capacity commitment in any scheduling interval.

        (III) Maximum changes. Subject to the minimum energy rate specified in subclause (I) of this clause and the maximum energy rate specified in subclause (II) of this clause, the energy scheduled by the entitlement holder in each hour cannot change more than plus or minus six MW.

      (v) Starts. The entitlement holder shall not direct more than 20 starts during the month of the entitlement, and the entitlement holder shall not direct more than one start per day. A start occurs every time a schedule increases the MW of energy from zero MW. Once the maximum number of starts have occurred during the entitlement, the energy scheduled by the entitlement holder may not be lower than a rate of five MW unless that level is lowered to zero MW, at which time the level may not be raised above zero MW for the remainder of the month.

      (vi) Default schedule. If the entitlement holder does not submit a timely day-ahead schedule as applicable, then the schedule for the applicable operating day is deemed to be, in every settlement interval of the applicable operating day, zero MW for the daily capacity commitment and zero MW of energy. This deemed schedule may not be changed.

    (F) Contract price for gas-cyclic. The items to be included in the contract price between the entitlement holder and the affiliated PGC for the entitlement shall include:

      (i) Capacity payment. The capacity payment from the entitlement holder to the affiliated PGC is the capacity price in dollars per MW specified in the letter confirmation for the entitlement times 25 MW.

      (ii) Energy payment.

        (I) The energy payment for each settlement interval from the entitlement holder to the affiliated PGC is the product, of the fuel price defined in subclause (II) of this clause times energy scheduled.

        (II) Fuel price.

          (-a-) The fuel price, for the portion of the daily capacity commitment that is designated by the entitlement holder by 8:00 a.m. in the day-ahead schedule, is the product of a heat rate equal to 12.100 MMBtu per MWh times the daily gas price.

          (-b-) The fuel price for the portion of the daily capacity commitment that is not released or committed at 8:00 a.m., but committed before the gas-cyclic start deadline, is the product of a heat rate equal to 12.100 MMBtu per MWh times (the sum of the daily gas price plus $ 0.25.)

    (G) Timing of payment of contract price. The entitlement holder shall pay the affiliated PGC the capacity payment portion of the contract price not less than five days before the beginning of the entitlement month or 20 days after receiving an invoice for the capacity payment from the affiliated PGC, whichever is later. The entitlement holder shall pay the remainder of the contract price after receiving an invoice for that amount in accordance with the terms of the Agreement. If the affiliated PGC owes the entitlement holder any net amount under the contract price calculation, it will pay that amount to the entitlement holder in accordance with the terms of the Agreement.

  (5) Gas-peaking product.

    (A) Description. The gas-peaking entitlement shall be intra-day power.

    (B) Block size. Each gas-peaking capacity entitlement shall be 25 MW in size.

    (C) Fuel price.

      (i) Except as specified in clause (ii) of this subparagraph, the fuel price owed to the affiliated PGC by the entitlement holder for gas- peaking capacity dispatched will be 14.100 MMBtu per MWh times the MWh of the gas-peaking power dispatched under the entitlement times the daily gas price.

      (ii) EGSI.

        (I) For EGSI gas-peaking capacity in the eastern congestion zone, the fuel cost owed to its affiliated PGC by the capacity entitlement holder for the gas-peaking capacity dispatched will be 14.100 MMBtu per MWh times the MWh of gas- peaking power dispatched under the entitlement times the Henry Hub daily gas price.

        (II) For EGSI gas-peaking capacity in the western congestion zone, the fuel cost owed to its affiliated PGC by the capacity entitlement holder for the gas-peaking capacity dispatched will be 14.100 MMBtu per MWh times the MWh of gas- peaking power dispatched under the entitlement times the average of the Henry Hub daily gas price and the Houston Ship Channel daily gas price.

    (D) Starts per month and associated costs. The entitlement holder of gas-peaking capacity shall be entitled to direct the selling affiliated PGC to make unlimited starts per month of each entitlement of gas-peaking capacity.

    (E) Gas-peaking scheduling.

      (i) Schedule types. The entitlement holder shall submit a day-ahead schedule for the entitlement and may submit hour-ahead schedules.

      (ii) Timing of scheduling.
