WALC will accept any number of scheduling changes during the day without additional charge. The charge will be allocated equally among all TSPs, both Federal and non-Federal, listed on schedules inside its BA Area. The Federal transmission segments of the 48413 schedule are exempt from invoicing since the costs for these segments are included in applicable transmission service rates. Formula Rate Annual Cost of Scheduling Personnel and Related Costs Number of Schedules per Year Charge per Schedule The charge per schedule, per day, is calculated by dividing the annual costs associated with scheduling (numerator) by the number of schedules per year (denominator). The numerator is the annual cost of transmission scheduling personnel, facilities, equipment, software, and other related costs involved in providing the service. The denominator is the yearly total of daily tags which result in a schedule, excluding schedules that return energy in kind. Based on the formula rate, the charge will be calculated each fiscal year using updated financial and schedule data. The charge will be effective on October 1st of each year and posted on WALC’s website.

[Note: This rate schedule was extended by Rate Order No. WAPA–200 through September 30, 2026.] Applicable In order to maintain transmission voltages on the transmission facilities within acceptable limits, generation facilities and non-generation resources capable of providing Reactive Supply and Voltage Control (VAR Support Service) are operated to produce (or absorb) reactive power. This service must be provided for each transaction on the transmission facilities within the Balancing Authority (BA) by the Transmission Service Provider (TSP) or the BA who performs this function for the TSP. VAR Support Service will be provided by the Western Area Lower Colorado Balancing Authority (WALC). Customers of a Federal TSP must purchase this service from WALC unless the transmission customer has generating resources capable of providing VAR Support Service directly to the Federal TSP and has executed a contract stipulating all the provisions of their self-supply. If WALC provides VAR Support Service on behalf of any non-Federal TSP, this service will be assessed on either the non-Federal TSP’s reserved capacity or the scheduled quantity of the non-Federal TSP’s customers.

That percentage is based on the nameplate power factor (one minus the power factor) for the generating units supplying the service within WALC. The denominator consists of the transmission transactions within WALC that require this service. Based on the formula rate, the charge will be calculated each fiscal year using updated financial and reservation data. The charge will be effective on October 1st of each year and will be posted on WALC’s website. Rate Schedule DSW–FR4 Applicable SCHEDULE 3 to OATT Regulation and Frequency Response Service (Regulation Service) is necessary to provide for the continuous balancing of resources, generation and interchange, with load, and for maintaining scheduled interconnection frequency at sixty cycles per second (60 Hz). The obligation to maintain this balance between resources and load lies with the Transmission Service Provider (TSP) or the Balancing Authority (BA) who performs this function for the TSP. The Western Area Lower Colorado Balancing Authority (WALC) performs this function for the Federal TSPs and must offer this service when transmission is used to serve load within its Balancing Authority Area (BA Area). Non-Federal TSPs and customers of Federal TSPs must purchase Regulation Service from WALC or make alternative comparable arrangements to satisfy their regulation obligations.

[Note: This rate schedule was extended by Rate Order No. WAPA–200 through September 30, 2026.] Formula Rate Annual Revenue Requirement for Regulation Service Load within W ALC Requiring Regulation Regulation Service Rate + (Installed Nameplate Capacity of Solar Generators Serving Load within W ALC x Solar Capacity Multiplier) + The numerator includes the annual costs associated with plant-in-service, operation and maintenance, purchase of regulation products, purchases of power to support WALC’s ability to regulate, and other related costs involved in providing the service. The denominator consists of the load within WALC that requires this service plus the product of the installed nameplate capacity of solar and wind generators serving load within WALC and the applicable capacity multipliers. Based on the formula rate, the charge will be calculated each fiscal year using updated financial and load data. The charge will be effective on October 1st of each year and will be posted on the WALC website. Types of Assessments There are two different applications of this formula rate: (1) A load-based assessment which is applicable to load within WALC (total metered load less Federal power allocation, including behind the meter VerDate Sep<11>2014 18:40 Aug 27, 2021 Jkt 253001 generation rating, or if available, hourly data if generation is synchronized) and the installed nameplate capacity of all intermittent resources serving load within WALC. (2) A self-provision assessment which allows entities with Automatic Generation Control (AGC) to selfprovide for all or a portion of their loads. Entities with AGC are known as Sub-Balancing Authorities (SBA) and must meet all of the following criteria: (a) Have a well-defined boundary, with WALC-approved revenue-quality metering, accurate as defined by the North American Electric Reliability Corporation (NERC), to include Megawatt (MW) flow data availability at 6-second or smaller intervals; (b) have AGC responsive unit(s); (c) demonstrate Regulation Service capability; and (d) execute a contract with WALC, provide all requested data, and meet the SBA error criteria below. Self-provision is measured by use of the entity’s 1-minute average Area Control Error (ACE) to determine the PO 00000 Frm 00030 Fmt 4703 Sfmt 4703 amount of self-provision. The ACE is used to calculate the Regulation Service charges every hour as follows: (1) If the entity’s 1-minute average ACE for the hour is less than or equal to 0.5 percent of its hourly average load, no charge is assessed for that hour. (2) If the entity’s 1-minute average ACE for the hour is greater than or equal to 1.5 percent of the entity’s hourly average load, WALC assesses charges using the hourly load-based assessment applied to the entity’s peak load for that month. (3) If the entity’s 1-minute average ACE for the hour is greater than 0.5 percent but less than 1.5 percent of its hourly average load, WALC assesses charges based on linear interpolation of no charge and full charge, using the hourly load-based assessment applied to the entity’s peak load for that month. WALC monitors the entity’s selfprovision on a regular basis. If WALC determines that the entity has not been attempting to self-regulate, WALC will, upon notification, employ the load- E:\FR\FM\30AUN1.SGM 30AUN1 EN30AU21.004</GPH> khammond on DSKJM1Z7X2PROD with NOTICES (Installed Nameplate Capacity of Wind Generators Serving Load within W ALC x Wind Capacity Multiplier) Federal Register / Vol. 86, No. 165 / Monday, August 30, 2021 / Notices based assessment methodology described above. Alternative Arrangements Exporting Intermittent Resource Requirement: An entity that exports the output from an intermittent generator to another BA Area will be required to dynamically meter or dynamically schedule that resource out of WALC to another BA unless arrangements, satisfactory to WALC, are made for that entity to acquire this service from a third-party or self-supply (as outlined below). An intermittent generator is one whose output is volatile and variable due to factors beyond direct operational control and, therefore, is not dispatchable. Self- or Third-party Supply: WALC may allow an entity to supply some or all of its required regulation, or contract with a third party. This entity must have revenue quality metering at every load and generation point, with accuracy as defined by NERC, to include MW flow data availability at 6-second (or smaller) intervals. WALC will evaluate the entity’s metering, telecommunications and regulating resource, as well as the required level of regulation, to determine whether the entity qualifies to self-supply under this provision. If approved, the entity is required to enter into a separate agreement with WALC which will specify the terms of selfsupply. Customer Accommodation For entities unwilling to take Regulation Service, self-provide as described above, or obtain the service from a third party, WALC will assist the entity in dynamically metering its loads/resources to another BA. Until such time as meter configuration is accomplished, the entity will be responsible for charges assessed under this schedule. Rate Schedule DSW–EI4 SCHEDULE 4 to OATT (Supersedes Rate Schedule DSW–EI3 dated October 1, 2016, Through September 30, 2021) United States Department of Energy khammond on DSKJM1Z7X2PROD with NOTICES Western Area Power Administration Desert Southwest Region and Western Area Lower Colorado Balancing Authority Energy Imbalance Service (Approved Under Rate Order No. WAPA–175) Effective The first day of the first full billing period beginning on or after October 1, VerDate Sep<11>2014 18:40 Aug 27, 2021 Jkt 253001 2016, and extending through September 30, 2021, or until superseded by another rate schedule, whichever occurs earlier. [Note: This rate schedule was extended by Rate Order No. WAPA–200 through September 30, 2026.] Applicable Energy Imbalance Service is provided when there is a difference between the scheduled and actual delivery of energy to a load located within a Balancing Authority Area (BA Area) over a single hour. The Transmission Service Provider (TSP) or the Balancing Authority (BA) who performs this function for the TSP must offer this service when transmission is used to serve load within its BA Area. The Western Area Lower Colorado Balancing Authority (WALC) performs this function for the Federal TSP. Customers of a Federal TSP must purchase this service from WALC or make alternative comparable arrangements to satisfy their Energy Imbalance obligations. Non-Federal TSPs must have separate agreements with WALC that specify the terms of Energy Imbalance Service. WALC may charge a transmission customer for either energy imbalances under this schedule or generator imbalances under Schedule 9 for imbalances occurring during the same hour, but not both unless the imbalances aggravate rather than offset each other. Formula Rate Charges for energy imbalances are based on the deviation bands as follows: 1. For deviations within ±1.5 percent (with a minimum of 4 MW) of the metered load, the settlement for on-peak and off-peak hours is 100 percent. 2. For deviations greater than ±1.5 up to 7.5 percent (or greater than 4 MW up to 10 MW) of the metered load, the settlement for on-peak hours is 110 percent for under-delivery and 90 percent for over-delivery, and the settlement for off-peak hours is 110 percent for under-delivery and 75 percent for over-delivery. 3. For deviations greater than ±7.5 percent (or 10 MW) of the metered load, the settlement for on-peak hours is 125 percent for under-delivery and 75 percent for over-delivery, and the settlement for off-peak hours is 125 percent for under-delivery and 60 percent for over-delivery. The deviation bands will be applied hourly and any energy imbalances that occur as a result of the transmission customer’s scheduled transactions will be netted on a monthly basis and settled financially at the end of the month. For purposes of this schedule, the proxy PO 00000 Frm 00031 Fmt 4703 Sfmt 4703 48415 prices used to determine financial settlement will be derived from the Palo Verde electricity price indexes, or similar alternative, for on-peak and offpeak. WALC may accept settlement in energy in lieu of financial settlement. During periods of BA operating constraints, WALC reserves the right to eliminate credits for over-delivery. The cost to WALC of any penalty assessed by a regulatory authority due to a violation of operating standards resulting from under or over-delivery of energy may be passed through to customers.

The TSP or the Balancing Authority (BA) who performs this function for the TSP must offer this service, to the extent it is physically feasible to do so from its resources or from resources available to it, when transmission is used to deliver energy from a generator located within its BA Area. The Western Area Lower Colorado Balancing Authority (WALC) performs this function for the Federal TSP. Customers of a Federal TSP must purchase this service from WALC or make alternative comparable arrangements to satisfy their generator imbalance obligations. Non-Federal TSPs must have separate agreements with WALC that specify the terms of Generator Imbalance Service.

An intermittent resource, for the limited purpose of this schedule, is an electric generator that is not dispatchable and cannot store its fuel source, and therefore cannot respond to changes in demand or respond to transmission security constraints. WALC may charge a transmission customer for either generator imbalances under this schedule or energy imbalances under Schedule 4 for imbalances occurring during the same hour, but not both unless the imbalances aggravate rather than offset each other. Formula Rate Charges for generator imbalances are based on the deviation bands as follows: 1. For deviations within ±1.5 percent (with a minimum of 4 MW) of the metered generation, the settlement for on-peak and off-peak hours is 100 percent. 2. For deviations greater than ±1.5 up to 7.5 percent (or greater than 4 MW up to 10 MW) of the metered generation, the settlement for on-peak hours is 110 E:\FR\FM\30AUN1.SGM 30AUN1 EN30AU21.006</GPH> ICost of Service EN30AU21.005</GPH> 48416 Federal Register / Vol. 86, No. 165 / Monday, August 30, 2021 / Notices percent for under-delivery and 90 percent for over-delivery, and the settlement for off-peak hours is 110 percent for under-delivery and 75 percent for over-delivery. 3. For deviations greater than ±7.5 percent (or 10 MW) of the metered generation, the settlement for on-peak hours is 125 percent for under-delivery and 75 percent for over-delivery, and the settlement for off-peak hours is 125 percent for under-delivery and 60 percent for over-delivery. An intermittent resource will be exempt from this deviation band but will be subject to the settlement provisions in the second deviation band for all deviations greater than ±7.5 percent (or 10 MW). The deviation bands will be applied hourly and any generator imbalances that occur as a result of the transmission customer’s scheduled transactions will be netted on a monthly basis and settled financially at the end of the month. For purposes of this schedule, the proxy prices used to determine financial settlement will be derived from the Palo Verde electricity price indexes, or similar alternative, for on-peak and offpeak. WALC may accept settlement in energy in lieu of financial settlement. During periods of BA operating constraints, WALC reserves the right to eliminate credits for over-delivery. The cost to WALC of any penalty assessed by a regulatory authority due to a violation of operating standards resulting from under or over-delivery of energy may be passed through to customers.

until superseded by another rate schedule, whichever occurs earlier. 
[Note: This rate schedule was extended by Rate Order No. WAPA-200 
through September 30, 2026.]

Applicable

    Scheduling, System Control, and Dispatch Service is required to 
schedule the movement of power through, out of, within, or into the 
Balancing Authority Area (BA Area). This service can be provided only 
by the operator in which the transmission facilities used for 
transmission service are located. The Western Area Lower Colorado 
Balancing Authority (WALC) performs this service for all Transmission 
Service Providers (TSPs) within its BA Area. The transmission customer 
must purchase this service, unless other arrangements are made with 
WALC.

[[Page 48413]]

    The charge will be applied to all schedules, except for schedules 
that return energy in kind to WALC. WALC will accept any number of 
scheduling changes during the day without additional charge. The charge 
will be allocated equally among all TSPs, both Federal and non-Federal, 
listed on schedules inside its BA Area. The Federal transmission 
segments of the schedule are exempt from invoicing since the costs for 
these segments are included in applicable transmission service rates.

Formula Rate
[GRAPHIC] [TIFF OMITTED] TN30AU21.002

    The charge per schedule, per day, is calculated by dividing the 
annual costs associated with scheduling (numerator) by the number of 
schedules per year (denominator). The numerator is the annual cost of 
transmission scheduling personnel, facilities, equipment, software, and 
other related costs involved in providing the service. The denominator 
is the yearly total of daily tags which result in a schedule, excluding 
schedules that return energy in kind.
    Based on the formula rate, the charge will be calculated each

Reactive Supply and Voltage Control From Generation Sources or Other 
Sources Service

(Approved Under Rate Order No. WAPA-175)

Effective

    The first day of the first full billing period beginning on or 
after October 1, 2016, and extending through September 30, 2021, or 
until superseded by another rate schedule, whichever occurs earlier. 
[Note: This rate schedule was extended by Rate Order No. WAPA-200 
through September 30, 2026.]

Applicable

    In order to maintain transmission voltages on the transmission 
facilities within acceptable limits, generation facilities and non-
generation resources capable of providing Reactive Supply and Voltage 
Control (VAR Support Service) are operated to produce (or absorb) 
reactive power. This service must be provided for each transaction on 
the transmission facilities within the Balancing Authority (BA) by the 
Transmission Service Provider (TSP) or the BA who performs this 
function for the TSP.
    VAR Support Service will be provided by the Western Area Lower 
Colorado Balancing Authority (WALC). Customers of a Federal TSP must 
purchase this service from WALC unless the transmission customer has 
generating resources capable of providing VAR Support Service directly 
to the Federal TSP and has executed a contract stipulating all the 
provisions of their self-supply. If WALC provides VAR Support Service 
on behalf of any non-Federal TSP, this service will be assessed on 
either the non-Federal TSP's reserved capacity or the scheduled 
quantity of the non-Federal TSP's customers.

Formula Rate
[GRAPHIC] [TIFF OMITTED] TN30AU21.003


[[Page 48414]]


    The numerator consists of the annual revenue requirement for 
generation multiplied by the percentage of resource capacity used for 
providing VAR Support Service. That percentage is based on the 
nameplate power factor (one minus the power factor) for the generating 
units supplying the service within WALC. The denominator consists of 
the transmission transactions within WALC that require this service.
    Based on the formula rate, the charge will be calculated each 
fiscal year using updated financial and reservation data. The charge 
will be effective on October 1st of each year and will be posted on 
WALC's website.

Regulation and Frequency Response Service

(Approved Under Rate Order No. WAPA-175)

Effective

    The first day of the first full billing period beginning on or 
after October 1, 2016, and extending through September 30, 2021, or 
until superseded by another rate schedule, whichever occurs earlier. 
[Note: This rate schedule was extended by Rate Order No. WAPA-200 
through September 30, 2026.]

Applicable

    Regulation and Frequency Response Service (Regulation Service) is 
necessary to provide for the continuous balancing of resources, 
generation and interchange, with load, and for maintaining scheduled 
interconnection frequency at sixty cycles per second (60 Hz). The 
obligation to maintain this balance between resources and load lies 
with the Transmission Service Provider (TSP) or the Balancing Authority 
(BA) who performs this function for the TSP. The Western Area Lower 
Colorado Balancing Authority (WALC) performs this function for the 
Federal TSPs and must offer this service when transmission is used to 
serve load within its Balancing Authority Area (BA Area). Non-Federal 
TSPs and customers of Federal TSPs must purchase Regulation Service 
from WALC or make alternative comparable arrangements to satisfy their 
regulation obligations.

Formula Rate
[GRAPHIC] [TIFF OMITTED] TN30AU21.004

    The numerator includes the annual costs associated with plant-in-
service, operation and maintenance, purchase of regulation products, 
purchases of power to support WALC's ability to regulate, and other 
related costs involved in providing the service. The denominator 
consists of the load within WALC that requires this service plus the 
product of the installed nameplate capacity of solar and wind 
generators serving load within WALC and the applicable capacity 
multipliers.
    Based on the formula rate, the charge will be calculated each 
fiscal year using updated financial and load data. The charge will be 
effective on October 1st of each year and will be posted on the WALC 
website.

Types of Assessments

    There are two different applications of this formula rate:
    (1) A load-based assessment which is applicable to load within WALC 
(total metered load less Federal power allocation, including behind the 
meter generation rating, or if available, hourly data if generation is 
synchronized) and the installed nameplate capacity of all intermittent 
resources serving load within WALC.
    (2) A self-provision assessment which allows entities with 
Automatic Generation Control (AGC) to self-provide for all or a portion 
of their loads. Entities with AGC are known as Sub-Balancing 
Authorities (SBA) and must meet all of the following criteria: (a) Have 
a well-defined boundary, with WALC-approved revenue-quality metering, 
accurate as defined by the North American Electric Reliability 
Corporation (NERC), to include Megawatt (MW) flow data availability at 
6-second or smaller intervals; (b) have AGC responsive unit(s); (c) 
demonstrate Regulation Service capability; and (d) execute a contract 
with WALC, provide all requested data, and meet the SBA error criteria 
below.
    Self-provision is measured by use of the entity's 1-minute average 
Area Control Error (ACE) to determine the amount of self-provision. The 
ACE is used to calculate the Regulation Service charges every hour as 
follows:
    (1) If the entity's 1-minute average ACE for the hour is less than 
or equal to 0.5 percent of its hourly average load, no charge is 
assessed for that hour.
    (2) If the entity's 1-minute average ACE for the hour is greater 
than or equal to 1.5 percent of the entity's hourly average load, WALC 
assesses charges using the hourly load-based assessment applied to the 
entity's peak load for that month.
    (3) If the entity's 1-minute average ACE for the hour is greater 
than 0.5 percent but less than 1.5 percent of its hourly average load, 
WALC assesses charges based on linear interpolation of no charge and 
full charge, using the hourly load-based assessment applied to the 
entity's peak load for that month.
    WALC monitors the entity's self-provision on a regular basis. If 
WALC determines that the entity has not been attempting to self-
regulate, WALC will, upon notification, employ the load-

[[Page 48415]]

based assessment methodology described above.

Alternative Arrangements

    Exporting Intermittent Resource Requirement: An entity that exports 
the output from an intermittent generator to another BA Area will be 
required to dynamically meter or dynamically schedule that resource out 
of WALC to another BA unless arrangements, satisfactory to WALC, are 
made for that entity to acquire this service from a third-party or 
self-supply (as outlined below). An intermittent generator is one whose 
output is volatile and variable due to factors beyond direct 
operational control and, therefore, is not dispatchable.
    Self- or Third-party Supply: WALC may allow an entity to supply 
some or all of its required regulation, or contract with a third party. 
This entity must have revenue quality metering at every load and 
generation point, with accuracy as defined by NERC, to include MW flow 
data availability at 6-second (or smaller) intervals. WALC will 
evaluate the entity's metering, telecommunications and regulating 
resource, as well as the required level of regulation, to determine 
whether the entity qualifies to self-supply under this provision. If 
approved, the entity is required to enter into a separate agreement 
with WALC which will specify the terms of self-supply.

Customer Accommodation

    For entities unwilling to take Regulation Service, self-provide as 
described above, or obtain the service from a third party, WALC will 
assist the entity in dynamically metering its loads/resources to 
another BA. Until such time as meter configuration is accomplished, the 
entity will be responsible for charges assessed under this schedule.

until superseded by another rate schedule, whichever occurs earlier. 
[Note: This rate schedule was extended by Rate Order No. WAPA-200 
through September 30, 2026.]

Applicable

    Energy Imbalance Service is provided when there is a difference 
between the scheduled and actual delivery of energy to a load located 
within a Balancing Authority Area (BA Area) over a single hour. The 
Transmission Service Provider (TSP) or the Balancing Authority (BA) who 
performs this function for the TSP must offer this service when 
transmission is used to serve load within its BA Area.
    The Western Area Lower Colorado Balancing Authority (WALC) performs 
this function for the Federal TSP. Customers of a Federal TSP must 
purchase this service from WALC or make alternative comparable 
arrangements to satisfy their Energy Imbalance obligations. Non-Federal 
TSPs must have separate agreements with WALC that specify the terms of 
Energy Imbalance Service. WALC may charge a transmission customer for 
either energy imbalances under this schedule or generator imbalances 
under Schedule 9 for imbalances occurring during the same hour, but not 
both unless the imbalances aggravate rather than offset each other.

Formula Rate

    Charges for energy imbalances are based on the deviation bands as 
follows:
    1. For deviations within 1.5 percent (with a minimum of 
4 MW) of the metered load, the settlement for on-peak and off-peak 
hours is 100 percent.
    2. For deviations greater than 1.5 up to 7.5 percent 
(or greater than 4 MW up to 10 MW) of the metered load, the settlement 
for on-peak hours is 110 percent for under-delivery and 90 percent for 
over-delivery, and the settlement for off-peak hours is 110 percent for 
under-delivery and 75 percent for over-delivery.
    3. For deviations greater than 7.5 percent (or 10 MW) 
of the metered load, the settlement for on-peak hours is 125 percent 
for under-delivery and 75 percent for over-delivery, and the settlement 
for off-peak hours is 125 percent for under-delivery and 60 percent for 
over-delivery.
    The deviation bands will be applied hourly and any energy 
imbalances that occur as a result of the transmission customer's 
scheduled transactions will be netted on a monthly basis and settled 
financially at the end of the month. For purposes of this schedule, the 
proxy prices used to determine financial settlement will be derived 
from the Palo Verde electricity price indexes, or similar alternative, 
for on-peak and off-peak. WALC may accept settlement in energy in lieu 
of financial settlement.
    During periods of BA operating constraints, WALC reserves the right 
to eliminate credits for over-delivery. The cost to WALC of any penalty 
assessed by a regulatory authority due to a violation of operating 
standards resulting from under or over-delivery of energy may be passed 
through to customers.

Applicable

    Spinning Reserve Service is needed to serve load immediately in the 
event of a system contingency and may be provided by generating units 
that are on-line and loaded at less than maximum output. The 
Transmission Service Provider (TSP) or the Balancing Authority (BA) who 
performs this function for the TSP must offer this service when 
transmission is used to serve load within its BA Area.
    The Western Area Lower Colorado Balancing Authority (WALC) performs

    Supplemental Reserve Service is needed to serve load in the event 
of a system contingency. It is not available immediately to serve load 
but is generally available within a short period of time after a system 
contingency event. This service may be provided by generating units 
that are on-line but unloaded, by quick-start generation, or by 
interruptible load. The Transmission Service Provider (TSP) or the 
Balancing Authority (BA) who performs this function for the TSP must 
offer this service when transmission is used to serve load within its 
BA Area.
    The Western Area Lower Colorado Balancing Authority (WALC) performs 
this function for the Federal TSP. Customers of a Federal TSP must 
purchase this service from WALC or make alternative arrangements to 
satisfy their Supplemental Reserve obligations.

Generator Imbalance Service

(Approved Under Rate Order No. WAPA-175)

Effective

    The first day of the first full billing period beginning on or 
after October 1, 2016, and extending through September 30, 2021, or 
until superseded by another rate schedule, whichever occurs earlier. 
[Note: This rate schedule was extended by Rate Order No. WAPA-200 
through September 30, 2026.]

Applicable

    Generator Imbalance Service is provided when a difference occurs 
between the output of a generator located in the Balancing Authority 
Area (BA Area) and the delivery schedule from that generator to another 
BA Area or a load within the Transmission Service Provider's (TSP) BA 
Area over a single hour. The TSP or the Balancing Authority (BA) who 
performs this function for the TSP must offer this service, to the 
extent it is physically feasible to do so from its resources or from 
resources available to it, when transmission is used to deliver energy 
from a generator located within its BA Area.
    The Western Area Lower Colorado Balancing Authority (WALC) performs 
this function for the Federal TSP. Customers of a Federal TSP must 
purchase this service from WALC or make alternative comparable 
arrangements to satisfy their generator imbalance obligations. Non-
Federal TSPs must have separate agreements with WALC that specify the 
terms of Generator Imbalance Service. An intermittent resource serving 
load outside WALC will be required to dynamically schedule or 
dynamically meter their generation to another BA Area unless 
arrangements, satisfactory to WALC, are made to acquire this service 
from a third-party. An intermittent resource, for the limited purpose 
of this schedule, is an electric generator that is not dispatchable and 
cannot store its fuel source, and therefore cannot respond to changes 
in demand or respond to transmission security constraints.
    WALC may charge a transmission customer for either generator 
imbalances under this schedule or energy imbalances under Schedule 4 
for imbalances occurring during the same hour, but not both unless the 
imbalances aggravate rather than offset each other.

Formula Rate

    Charges for generator imbalances are based on the deviation bands 
as follows:
    1. For deviations within 1.5 percent (with a minimum of 
4 MW) of the metered generation, the settlement for on-peak and off-
peak hours is 100 percent.
    2. For deviations greater than 1.5 up to 7.5 percent 
(or greater than 4 MW up to 10 MW) of the metered generation, the 
settlement for on-peak hours is 110

[[Page 48417]]

percent for under-delivery and 90 percent for over-delivery, and the 
settlement for off-peak hours is 110 percent for under-delivery and 75 
percent for over-delivery.
    3. For deviations greater than 7.5 percent (or 10 MW) 
of the metered generation, the settlement for on-peak hours is 125 
percent for under-delivery and 75 percent for over-delivery, and the 
settlement for off-peak hours is 125 percent for under-delivery and 60 
percent for over-delivery. An intermittent resource will be exempt from 
this deviation band but will be subject to the settlement provisions in 
the second deviation band for all deviations greater than 7.5 percent (or 10 MW).
    The deviation bands will be applied hourly and any generator 
imbalances that occur as a result of the transmission customer's 
scheduled transactions will be netted on a monthly basis and settled 
financially at the end of the month. For purposes of this schedule, the 
proxy prices used to determine financial settlement will be derived 
from the Palo Verde electricity price indexes, or similar alternative, 
for on-peak and off-peak. WALC may accept settlement in energy in lieu 
of financial settlement.
    During periods of BA operating constraints, WALC reserves the right 
to eliminate credits for over-delivery. The cost to WALC of any penalty 
assessed by a regulatory authority due to a violation of operating 
standards resulting from under or over-delivery of energy may be passed 
through to customers.

    Capacity and energy losses occur when a Transmission Service 
Provider (TSP) delivers electricity over its transmission facilities 
for a transmission customer. The Western Area Lower Colorado Balancing 
Authority (WALC) provides this service to TSPs within its Balancing 
Authority Area (BA Area). Transmission losses (losses) are assessed for 
transactions on transmission facilities within WALC, unless separate 
agreements specify the terms for losses. The losses applicable to 
Federal TSPs will be passed directly to transmission customers. The 
transmission customer must either purchase this service from WALC or 
make alternative comparable arrangements to satisfy their obligations 
for losses.

Formula Rate

    The loss percentage currently in effect is posted on WALC's website 
and may be changed from time to time. Financial settlement for losses 
will occur on a monthly basis, unless determined by WALC. Proxy prices 
used to determine financial settlement will be derived from the Palo

Unreserved Use Penalties

(Approved Under Rate Order No. WAPA-175)

Effective

    The first day of the first full billing period beginning on or

until superseded by another rate schedule, whichever occurs earlier. 
[Note: This rate schedule was extended by Rate Order No. WAPA-200 
through September 30, 2026.]

Applicable

    Unreserved use occurs when a customer uses transmission service it 
has not reserved or uses transmission service in excess of its reserved 
capacity. Unreserved use may also include a transmission customer's 
failure to curtail transmission when requested. The transmission 
customer shall compensate the Federal Transmission Service Provider 
(TSP) each month for any unreserved use of the transmission system.

Penalty Rate

    The charge for a transmission customer that engages in unreserved 
use is two times the maximum allowable firm point-to-point transmission 
rate for the service at issue, assessed as follows:
    (1) The penalty for one instance, in a single hour, is based on the 
daily rate;
    (2) The penalty for more than one instance, for any given duration 
(e.g., daily) increases to the next longest duration (e.g., weekly).
    A transmission customer that exceeds its reserved capacity at any 
point of receipt or point of delivery, or a customer that uses 
transmission service at a point of receipt or point of delivery that it 
has not reserved, is required to pay for all ancillary services 
provided by the Federal TSP and associated with the unreserved use. The 
customer will pay for ancillary services based on the amount of 
transmission service it used and did not reserve.
