RULE §25.381Capacity Auctions

        (II) The entitlement holder may submit to the affiliated PGC a revised day-ahead or two-day-ahead schedule for energy from the entitlement no later than 10:00 a.m.

        (III) On days that ERCOT allows QSEs to change their day-ahead or two-day ahead schedules to ERCOT by 1:00 p.m. for congestion or capacity insufficiency, the entitlement holder may submit a revised day-ahead or two-day-ahead schedule for energy from the entitlement to the affiliated PGC no later than noon.

        (IV) The entitlement holder may submit to the affiliated PGC a revised day-ahead or two-day-ahead schedule for the non- spinning reserve service from the entitlement no later than 1:45 p.m.

        (V) The gas-peaking start deadline for declaring the daily capacity commitment for each settlement interval in an operating hour is one hour before the end of the adjustment period for that operating hour.

      (iii) Schedule content. Each schedule shall specify:

        (I) For each settlement interval, the MW of energy scheduled to be delivered to the entitlement holder from the entitlement; and

        (II) For each hour, the MW scheduled to be reserved for the entitlement holder's use of the non-spinning reserve service from the entitlement.

      (iv) Scheduling limits.

        (I) Total.

          (-a-) The rate at which energy is scheduled or ancillary services reserved or scheduled by the entitlement holder in each settlement interval during an hour shall be either zero MW or 25 MW and cannot change during the hour.

          (-b-) Subject to the requirement of item (-a-) of this subclause, if the entitlement holder schedules any energy from the entitlement in an hour, the rate at which energy is scheduled shall continue uninterrupted at a level of 25 MW for not less than four hours.

          (-c-) Subject to the requirements of items (-a-) and (-b-) of this subclause, when the entitlement holder decreases a schedule for energy to zero MW from the entitlement in an hour, the rate at which energy is scheduled or at which ancillary services is scheduled or reserved shall continue uninterrupted at a level of zero MW for not less than two hours.

        (II) Starts. The number of starts of the entitlement is not limited.

      (v) Default schedule. If the entitlement holder does not submit a timely day-ahead or two-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, zero MW of energy, and zero MW of the non-spinning reserve service. This deemed schedule may not be changed in any revised day-ahead or two-day ahead schedule, or in any hour-ahead schedule.

    (B) Gas-peaking ancillary services. The entitlement holder may not use the entitlement for any ancillary service except the non-spinning reserve service.

    (C) Contract price for gas-peaking. 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 fuel price defined in subclause (II) of this clause times (energy scheduled plus non-spinning energy deployed plus non- spinning energy instructed deviation.)

        (II) Fuel price.

          (-a-) The fuel price, for operating days for which the entitlement holder designated its daily capacity commitment by 8:00 a.m. in the day-ahead or two- day ahead schedule, is a heat rate equal to 14.100 MMBtu per MWh times the daily gas price.

          (-b-) The fuel price, for operating days for which the entitlement holder exercises its option to designate its daily capacity commitment after 8:00 a.m. and before the gas-peaking start deadline, is a heat rate equal to 14.100 MMBtu per MWh times the sum of the daily gas price plus $ .25.

      (iii) Ancillary services payment. The ancillary services payment to be paid by the entitlement holder to the affiliated PGC is the product of $1.00 per MW times the total number of MW of non-spinning reserve service scheduled during each hour of the entitlement month.

      (iv) Ancillary services reimbursement payment. The ancillary services reimbursement payment from the affiliated PGC to the entitlement holder is the sum of the MCPE for energy in dollars per MWh paid by ERCOT for each MWh of non-spinning energy deployed and the price that ERCOT pays for uninstructed deviations for each MWh of non-spinning energy uninstructed deviation.

    (D) 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 other 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 other terms of the Agreement.

(g) Product descriptions for capacity in non-ERCOT areas. The provisions in this subsection apply to capacity auctions in non-ERCOT areas. Subsection (f) of this section contains provisions applicable to capacity auctions in ERCOT.

  (1) Definitions. The following words and terms when used in this subsection shall have the following meanings unless the context indicates otherwise:

    (A) Daily capacity commitment--The amount of capacity scheduled by the entitlement holder that a seller shall make available for the provision of energy from an entitlement.

    (B) Day ahead schedule--A schedule submitted by the entitlement holder to a seller of the entitlement holder's scheduled usage of the entitlement for the following operating day.

    (C) Energy scheduled--For each settlement interval, the final schedule for energy that the entitlement holder submits to a seller, subject to the limits on timing and amounts of schedules contained in this subsection.

    (D) Grouped entitlements--All of the entitlements from a seller that the entitlement holder holds for a particular entitlement month.

    (E) Hour-ahead schedule--A schedule other than a day-ahead schedule submitted by the entitlement holder to a seller of the entitlement holder's scheduled usage of the entitlement for the following operating hour.

  (2) Baseload product.

    (A) Description. For each baseload capacity entitlement, the scheduled power shall be provided to the entitlement holder during the month of the entitlement seven days per week and 24 hours per day, in accordance with the scheduling requirements and limitations provided in subparagraph (E) of this paragraph.

    (B) Block size. Each baseload capacity entitlement shall be 25 MW in size.

    (C) Fuel price. The fuel cost owed to the affiliated PGC by the entitlement holder for the dispatched baseload power will be the average cost of coal, lignite, and nuclear fuel, in dollars per MWh, based on the company's final ECOM model as determined in the proceeding pursuant to PURA §39.201 as projected for the relevant time period. Electric utilities without an ECOM determination in their proceeding conducted pursuant to PURA §39.201 shall propose for commission review an average cost of fuel in a similar manner.

    (D) Starts per month. The entitlement holder of a baseload capacity entitlement shall take power from the entitlement seven days per week and 24 hours per day and is therefore not permitted to direct the affiliated PGC to make any starts of baseload capacity entitlements.

    (E) Baseload 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 the seller no later than 8:00 a.m. The daily capacity commitment is determined for a baseload entitlement by the 8:00 a.m. schedule.

        (II) The entitlement holder may submit to the 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 baseload entitlements.

      (iii) Schedule content. Each schedule shall specify, for each scheduling interval, subject to the scheduling limits in clause (iv) of this subparagraph, the energy scheduled to be delivered to the entitlement holder from the entitlement.

      (iv) Scheduling limits.
