schedule the movement of power through, out of, within, or into the 
Southwest Power Pool, Inc. (SPP) Balancing Authority Area and/or the 
Western Area Power Administration, Upper Great Plains West Balancing 
Authority Area (WAUW). Western Area Power Administration-Upper Great 
Plains (Western-UGP) region's annual revenue requirement for SSCD will 
be used by SPP to calculate the regional SPP Schedule 1 rate for SPP 
through and out transactions, and also to calculate the zonal SPP 
Schedule 1 rate for the Upper Missouri Zone (UMZ or Zone 19). This rate 
will also be charged by SPP for SPP Transmission Service provided 
within the UMZ in the Western Interconnection.

Formula Rate

Define
A = Operation & Maintenance for SSCD ($)
B = Administrative and General Expense for SSCD ($)
C = Depreciation for SSCD ($)
D = Taxes Other than Income Taxes for Transmission ($)
E = Allocation of General Plant for SSCD ($)
F = Cost of Capital for SSCD ($)

Division

Regulation and Frequency Response Service--WAUW

(Approved Under Rate Order No. WAPA-188)

Effective

    Beginning on October 1, 2020, and remaining in effect through 
September 30, 2025, or until superseded by another rate schedule, 
whichever occurs earlier. Notification of the effective date of the 
formula rates will be published in the Federal Register. [Note: This 
rate schedule was extended by Rate Order No. WAPA-217 through September 
30, 2030.]

Applicable

    This Rate Schedule applies to the Western Area Power 
Administration, Upper Great Plains West Balancing Authority Area 
(WAUW). Regulation and Frequency Response Service (Regulation) is 
necessary to provide for the continuous balancing of resources, 
generation, and interchange with load and for maintaining scheduled 
interconnection frequency at 60 cycles per second (60 Hz). Regulation 
is accomplished by committing on-line generation whose output is raised 
or lowered, predominantly through the use of automatic generating 
control equipment, as necessary, to follow the moment-by-moment changes 
in load. The obligation to maintain this balance between resources and 
load lies with the Western Area Power Administration-Upper Great Plains 
(Western-UGP) region as the WAUW operator. The SPP Transmission 
Customer must either purchase this service from SPP or make alternative 
comparable arrangements pursuant to the SPP Tariff to satisfy its 
Regulation obligation. Western-UGP's annual revenue requirement for 
Regulation (outlined below) will be used by SPP to calculate the WAUW 
charges for Regulation.
    Western-UGP supports the installation of renewable sources of 
energy but recognizes that certain operational constraints exist in 
managing the significant fluctuations that are a normal part of their 
operation. When Western-UGP purchases power resources to provide 
Regulation to intermittent resources serving load within Western-UGP's 
WAUW, costs for these regulation resources will become part of 
Western's Regulation revenue requirement, which will be billed by SPP, 
as the Transmission Provider, to a SPP Transmission Customer along with 
the associated transmission service provided by SPP under the SPP 
Tariff. However, Western-UGP will not regulate for the difference 
between the output of an intermittent resource located within Western- 
UGP's WAUW and a delivery schedule from that generator serving load 
located outside of Western-UGP's WAUW. Intermittent resources serving 
load outside Western-UGP's WAUW will be required to be pseudo-tied or 
dynamically scheduled to another Balancing Authority Area.
    An intermittent resource, for the limited purpose of this Rate 
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.

Formula Rate

Define
A = U.S. Army Corps of Engineers (Corps) Fixed Charge Rate (%)
B = Corps Generation Net Plant Costs ($)
C = Plant Capacity (kW)
D = Capacity Used for Regulation (kW-year)
E = Capacity Purchases for Regulation ($)
F = Prior Period True-up
Regulation Annual Revenue Requirement = (A * B/C) * D + E + F

    A recalculated revenue requirement will go into effect every 
January 1 based on the above formula and updated financial data. 
Western-UGP will annually notify SPP and make data and information 
available to interested parties for review and comment related to the 
recalculated annual revenue requirement on or shortly after September 1 
of the preceding year. Data used and the charges resulting from using 
this formula will be posted on the applicable SPP website and Western-
UGP's Open Access Same-Time Information System (OASIS).

Rate Schedule WAUW-AS4, October 1, 2025

(Supersedes Rate Schedule WAUW-AS4 Dated October 1, 2020, Through 
September 30, 2025)

United States Department of Energy Western Area Power Administration

Upper Great Plains Region Pick-Sloan Missouri Basin Program--Eastern 
Division

Energy Imbalance Service--WAUW

(Approved Under Rate Order No. WAPA-188)

Effective

    Beginning on October 1, 2020, and remaining in effect through 
September 30, 2025, or until superseded by another rate schedule, 
whichever occurs earlier. Notification of the effective date of the 
formula rates will be published in the Federal Register. [Note: This 
rate schedule was extended by Rate Order No. WAPA-217 through September 
30, 2030.]

Applicable

    This Rate Schedule applies to the Western Area Power 
Administration, Upper Great Plains West Balancing Authority Area 
(WAUW). Energy Imbalance Service is provided when a difference occurs 
between scheduled and actual delivery of energy to a load located 
within Western Area Power Administration-Upper Great Plains (Western-
UGP) region's WAUW over a single hour (or different dispatch interval 
for energy imbalance service market, if applicable). Given the 
Southwest Power Pool, Inc. (SPP) Integrated Marketplace does not extend 
into the Western Interconnection, Western-UGP, as the Balancing 
Authority, will offer to provide Energy Imbalance Service in the WAUW 
at the request of SPP, if it is capable of doing so, from its own 
resources or from resources available to it including possible 
participation in a Western Interconnection energy imbalance service 
market. SPP is the Transmission Provider for the eligible Western-UGP 
facilities transferred to the functional control of SPP in the WAUW. 
Energy Imbalance Service is needed when transmission service is 
provided by SPP and used to serve load within the WAUW, or when a 
difference occurs between the expected and actual delivery of energy 
to/from the WAUW over a single hour (or different dispatch interval for 
energy imbalance service market, if applicable) in the event that 
Western-UGP participates in a Western Interconnection energy imbalance 
service market in the WAUW as the Balancing Authority. Energy Imbalance 
Service in the WAUW will be billed by SPP to the SPP Transmission 
Customer along with the associated transmission service provided by 
SPP. The SPP Transmission Customer must either purchase this service 
from SPP, or make alternative comparable arrangements pursuant to the 
SPP Tariff to satisfy its Energy Imbalance Service obligation.
    The SPP Transmission Customer will incur a charge for either hourly 
energy imbalances under this Schedule, WAUW-AS4, or hourly generator 
imbalances under Rate Schedule WAUW-AS7 for imbalances occurring during 
the same hour, but not both, unless the imbalances aggravate rather 
than offset each other.

Formula Rate

    (A) In the event that Western-UGP does not participate in a Western 
Interconnection energy imbalance service market in the WAUW as the 
Balancing Authority, or such energy imbalance market is unable to 
provide the total energy imbalance requirements for certain loads and 
generation within the Balancing Authority Area:
    For deviations within +/- 1.5 percent (with a minimum of 2 MW) of 
the scheduled transaction to be applied hourly to any energy imbalance 
that occurs as a result of the SPP Transmission Customer's scheduled 
transaction(s) will be netted on a monthly basis and settled 
financially, at the end of the month, at 100 percent of the average 
incremental cost.
    Deviations greater than +/- 1.5 percent up to 7.5 percent (or 
greater than 2 MW up to 10 MW) of the scheduled transaction to be 
applied hourly to any energy imbalance that occurs as a result of the 
SPP Transmission Customer's scheduled transaction(s) will be settled 
financially, at the end of each month. When energy taken in a schedule 
hour is greater than the energy scheduled, the charge is 110 percent of 
incremental cost. When energy taken is less than the scheduled amount, 
the credit is 90 percent of the incremental cost.
    Deviations greater than +/- 7.5 percent (or 10 MW) of the scheduled 
transaction to be applied hourly to any energy imbalance that occurs as 
a result of the SPP Transmission Customer's scheduled transaction(s) 
will be settled at 125 percent of Western-UGP's incremental cost when 
energy taken in a schedule hour is greater than the energy scheduled or 
75 percent of Western- UGP's incremental cost when energy taken by a 
SPP Transmission Customer is less than the scheduled amount.
    Western-UGP's incremental cost will be based upon a representative 
hourly energy index or combination of indexes. The index to be used 
will be posted on the applicable SPP website and Western-UGP's Open 
Access Same-Time Information System (OASIS) at least 30 days before use 
for determining the Western-UGP incremental cost and will not be 
changed more often than once per year unless Western-UGP determines 
that the existing index is no longer a reliable price index.
    The pricing and charge for deviations in the above deviation 
bandwidths is as specified above. Data used and the charges resulting 
from using this formula will be posted on the applicable SPP website 
and Western-UGP's OASIS.
    (B) In the event that Western-UGP participates in a Western 
Interconnection energy imbalance service market in the WAUW as the 
Balancing Authority:
    Charges to the SPP Transmission Customer will reflect only the 
pass-through of the applicable charges associated with the Western 
Interconnection energy imbalance service market assessed to Western-UGP 
as the WAUW Balancing Authority for embedded load and/or generation in 
the WAUW of such SPP Transmission Customer that does not make adequate 
alternate arrangements in such Western Interconnection energy imbalance 
service market or other alternative comparable arrangements pursuant to 
the SPP Tariff to satisfy its Energy Imbalance Service obligation.
    Western-UGP will post notice on the applicable SPP website and 
Western-UGP's OASIS, and also notify existing SPP Transmission 
Customers, at least 30 days before Western-UGP participates in a 
Western Interconnection energy imbalance service market, as the 
Balancing Authority. Western-UGP will also post information related to 
the charges assessed by the market operator for Energy Imbalance 
Service in the WAUW under such Western Interconnection energy imbalance 
service market.
    Data used and the charges resulting from using this formula will be 
posted on the applicable SPP website and Western-UGP's OASIS.

Applicable

    This Rate Schedule applies to the Western Area Power 
Administration, Upper Great Plains West Balancing Authority Area 
(WAUW). Operating Reserve-Spinning Reserve Service (Spinning Reserves) 
is needed to serve load immediately in the event of a system 
contingency. Spinning Reserves may be provided by generating units that 
are on-line and loaded at less than maximum output. Given the Southwest 
Power Pool, Inc. (SPP) Integrated Marketplace does not extend into the 
Western Interconnection, Western Area Power Administration-Upper Great 
Plains (Western-UGP) region, as the Balancing Authority, will offer to 
provide Spinning Reserves, if available, at the request of SPP as the 
Transmission Provider in the WAUW. Operating Reserve-Spinning Reserve 
Service in the WAUW will be billed by SPP to the SPP Transmission 
Customer along with the associated transmission service provided by 
SPP. The SPP Transmission Customer must either purchase this service 
from SPP or make alternative comparable arrangements pursuant to the 
SPP Tariff to satisfy its Spinning Reserves obligation. Western-UGP's 
annual revenue requirement for Spinning Reserves (outlined below) will 
be utilized by SPP to calculate the WAUW charges for Spinning Reserves.

Formula Rate

Define
A = U.S. Army Corps of Engineers (Corps) Fixed Charge Rate (%)
B = Corps Generation Net Plant Costs ($)

    A recalculated revenue requirement will go into effect every 
January 1 based on the above formula and updated financial, load/
generation, and Reserve Sharing Program requirements data. Western-UGP 
will annually notify SPP and make data and information available to 
interested parties for review and comment related to the recalculated 
annual revenue requirement on or shortly after September 1 of the 
preceding year. Data used and the charges resulting from using this 
formula will be posted on the applicable SPP website and Western-UGP's 
Open Access Same-Time Information System (OASIS).
    If resources are not available from a Western-UGP resource, 
Western-UGP, at the request of SPP as the Transmission Provider, will 
offer to purchase the Spinning Reserves and pass through the costs, 
plus an amount for administration, to SPP for the SPP Transmission 
Customer.
    In the event that Spinning Reserves are called upon for emergency 
use, the SPP Transmission Customer will be assessed a charge for energy 
used at the prevailing market energy rate in the WAUW. The prevailing 
market energy rate will be based upon a representative hourly energy 
index or combination of indexes. The index to be used will be posted on 
the applicable SPP website and Western-UGP's OASIS at least 30 days 
before use for determining the prevailing market energy rate and will 
not be changed more often than once per year unless Western-UGP 
determines that the existing index is no longer a reliable price index. 
The SPP Transmission Customer would be responsible for providing 
transmission service to get the Spinning Reserves to its destination.

Applicable

    This Rate Schedule applies to the Western Area Power 
Administration, Upper Great Plains West Balancing Authority Area 
(WAUW). Operating Reserve-Supplemental Reserve Service (Supplemental 
Reserves) is needed to serve load in the event of a system contingency; 
however, it is not available immediately to serve load but rather 
within a short period of time.
    Supplemental Reserves may be provided by generating units that are 
on-line but unloaded, by quick-start generation, or by interruptible 
load. Given the Southwest Power Pool, Inc. (SPP) Integrated Marketplace 
does not extend into the Western Interconnection, Western Area Power 
Administration-Upper Great Plains (Western-UGP) region, as the 
Balancing Authority, will offer to provide Supplemental Reserves, if 
available, at the request of SPP as the Transmission Provider, in the 
WAUW. Operating Reserve-Supplemental Reserve Service in the WAUW will 
be billed by SPP to the SPP Transmission Customer along with the 
associated transmission service provided by SPP. The SPP Transmission 
Customer must either purchase this service from SPP or make alternative 
comparable arrangements pursuant to the SPP Tariff to satisfy its

Supplemental Reserves obligation. Western-UGP's annual revenue 
requirement for Supplemental Reserves (outlined below) will be utilized 
by SPP to calculate the WAUW charges for Supplemental Reserves.

Generator Imbalance Service--WAUW

(Approved Under Rate Order No. WAPA-188)

Effective

    Beginning on October 1, 2020, and remaining in effect through 
September 30, 2025, or until superseded by another rate schedule, 
whichever occurs earlier. Notification of the effective date of the 
formula rates will be published in the Federal Register. [Note: This 
rate schedule was extended by Rate Order No. WAPA-217 through September 
30, 2030.]

Applicable

    This Rate Schedule applies to the Western Area Power 
Administration, Upper Great Plains West Balancing Authority Area 
(WAUW). Generator Imbalance Service is provided when a difference 
occurs between the output of a generator located within Western Area 
Power Administration-Upper Great Plains (Western-UGP) region's WAUW and 
a delivery schedule from that generator to (1) another Balancing 
Authority Area or (2) a load within Western-UGP's WAUW over a single 
hour (or different dispatch interval for energy imbalance service 
market, if applicable). Given the Southwest Power Pool, Inc. (SPP) 
Integrated Marketplace does not extend into the Western 
Interconnection, Western-UGP, as the Balancing Authority, will offer to 
provide this service at the request of SPP, if it is capable of doing 
so, from its own resources or from resources available to it including 
possible participation in a Western Interconnection energy imbalance 
service market. SPP is the Transmission Provider for the eligible 
Western-UGP facilities transferred to the functional control of SPP in 
the WAUW. Generator Imbalance Service is needed when transmission 
service is provided by SPP and used to deliver energy from a generator 
located within the WAUW, or when a difference occurs between the 
expected and actual delivery of energy to/from the WAUW over a single 
hour (or different dispatch interval for energy imbalance service 
market, if applicable) in the event that Western-UGP participates in a 
Western Interconnection energy imbalance service market in the WAUW as 
the Balancing Authority. Generator Imbalance Service in the WAUW will 
be billed by SPP to the SPP Transmission Customer along with the 
associated transmission service provided by SPP. The SPP Transmission 
Customer must either purchase this service from SPP or make alternative 
comparable arrangements pursuant to the SPP Tariff, to satisfy its 
Generator Imbalance Service obligation. The SPP Transmission Customer 
will incur a charge for either hourly generator imbalances under this 
Schedule, WAUW-AS7, or hourly energy imbalances under Rate Schedule 
WAUW-AS4 for imbalances occurring during the same hour, but not both, 
unless the imbalances aggravate rather than offset each other.
    Western-UGP supports the installation of renewable sources of 
energy but recognizes that certain operational constraints exist in 
managing the significant fluctuations that are a normal part of their 
operation. Western-UGP has marketed the maximum practical amount of 
power from each of its projects, leaving little or no flexibility for 
provision of additional power services. Consequently, Western-UGP will 
not regulate for the difference between the output of an intermittent 
resource located within the WAUW and a delivery schedule from that 
generator serving load located outside of the WAUW. Intermittent 
resources serving load outside Western-UGP's WAUW will be required to 
be pseudo-tied or dynamically scheduled to another Balancing Authority 
Area.
    An intermittent resource, for the limited purpose of this Rate 
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.

    (A) In the event that Western-UGP does not participate in a Western 
Interconnection energy imbalance

[[Page 104150]]

service market in the WAUW as the Balancing Authority, or such energy 
imbalance market is unable to provide the total energy imbalance 
requirements for certain loads and generation within the Balancing 
Authority Area:
    For deviations within +/- 1.5 percent (with a minimum of 2 MW) of 
the scheduled transaction to be applied hourly to any generator 
imbalance that occurs as a result of the SPP Transmission Customer's 
scheduled transaction(s) will be netted on a monthly basis and settled 
financially, at the end of the month, at 100 percent of the average 
incremental cost.
    Deviations greater than +/- 1.5 percent up to 7.5 percent (or 
greater than 2 MW up to 10 MW) of the scheduled transaction to be 
applied hourly to any generator imbalance that occurs as a result of 
the SPP Transmission Customer's scheduled transaction(s) will be 
settled financially, at the end of each month. When energy delivered in 
a schedule hour from the generation resource is less than the energy 
scheduled, the charge is 110 percent of incremental cost. When energy 
delivered from the generation resource is greater than the scheduled 
amount, the credit is 90 percent of the incremental cost.
    Deviations greater than +/- 7.5 percent (or 10 MW) of the scheduled 
transaction to be applied hourly to any generator imbalance that occurs 
as a result of the SPP Transmission Customer's scheduled transaction(s) 
will be settled at 125 percent of Western-UGP's highest incremental 
cost for the day when energy delivered in a schedule hour is less than 
the energy scheduled or 75 percent of Western-UGP's lowest daily 
incremental cost when energy delivered from the generation resource is 
greater than the scheduled amount. As an exception, an intermittent 
resource will be exempt from this deviation band and will pay the 
deviation band charges for all deviations greater than the larger of 
1.5 percent or 2 MW.
    Deviations from scheduled transactions responding to directives by 
the Transmission Provider, a Balancing Authority, or a reliability 
coordinator will not be subject to the deviation bands identified above 
and, instead, will be settled financially, at the end of the month, at 
100 percent of incremental cost. Such directives may include 
instructions to correct frequency decay, respond to a reserve sharing 
event, or change output to relieve congestion.
    Western-UGP's incremental cost will be based upon a representative 
hourly energy index or combination of indexes. The index to be used 
will be posted on the applicable SPP website and Western-UGP's Open 
Access Same-Time Information System (OASIS) at least 30 days before use 
for determining the Western-UGP incremental cost and will not be 
changed more often than once per year unless Western-UGP determines 
that the existing index is no longer a reliable price index.
    The pricing and charge for deviations in the deviation bandwidths 
is as specified above. Data used and the charges resulting from using 
this formula will be posted on the applicable SPP website and Western-
UGP's OASIS.
    (B) In the event that Western-UGP participates in a Western 
Interconnection energy imbalance service market in the WAUW as the 
Balancing Authority:
    Charges to the SPP Transmission Customer will reflect only the 
pass-through of the applicable charges associated with the Western 
Interconnection energy imbalance service market assessed to Western-UGP 
as the WAUW Balancing Authority for embedded load and/or generation in 
the WAUW of such SPP Transmission Customer that does not make adequate 
alternate arrangements in such Western Interconnection energy imbalance 
service market or other alternative comparable arrangements pursuant to 
the SPP Tariff to satisfy its Generator Imbalance Service obligation.
    Western-UGP will post notice on the applicable SPP website and 
Western-UGP's OASIS, and also notify existing Transmission Customers, 
at least 30 days before Western-UGP participates in a Western 
Interconnection energy imbalance service market, as the Balancing 
Authority. Western-UGP will also post information related to the 
charges assessed by the market operator for Generator Imbalance Service 
in the WAUW under such Western Interconnection energy imbalance service 
market.
    Data used and the charges resulting from using this formula will be 
posted on the applicable SPP website and Western-UGP's OASIS.
