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 WesternUGP’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 passthrough 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 WesternUGP’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.
