procedures set forth at 10 CFR part 

903(a).3

Background 

On January 12, 2017, FERC confirmed 

and approved Rate Schedules PD–NTS4 

(Network), INT–NTS4 (Network), DSW– 

SD4 (Scheduling, System Control, and 

Dispatch), DSW–RS4 (Reactive Supply 

and Voltage Control), DSW–FR4 

(Regulation and Frequency Response),

SPR4 (Spinning Reserve), DSW–SUR4 

(Supplemental Reserve), DSW–GI2 

(Generator Imbalance), DSW–TL1 

(Transmission Losses), and DSW–UU1 

(Unreserved Use Penalties) under Rate 

Order No. WAPA–175 on a final basis 

for a 5-year period through September 

30, 2021.4 These rate schedules apply to 

Parker-Davis Project and Pacific 

Northwest-Pacific Southwest Intertie 

Project network integration transmission 

service, along with transmission losses, 

unreserved use penalties, and ancillary 

services from WAPA’s Desert 

Southwestern Region (DSW) and 

Western Area Lower Colorado Balancing 

Authority (WALC). The existing formula 

rates for these services provide adequate 

revenue to recover all expenses incurred 

for providing each service. This ensures 

repayment within the cost recovery 

criteria set forth in DOE Order RA 

6120.2. 

Discussion 

In accordance with 10 CFR 903.23(a), 

WAPA filed a notice in the Federal 

Register on July 8, 2021, proposing to 

extend, without adjustment, Rate 

Schedules PD–NTS4, INT–NTS4, DSW– 

SD4, DSW–RS4, DSW–FR4, DSW–EI4, 

DSW–SPR4, DSW–SUR4, DSW–GI2, 

DSW–TL1, and DSW–UU1 under Rate 

Order No. WAPA–200.5 WAPA 

determined it was not necessary to hold 

public information or public comment 

forums on the proposed formula rate 

extension, but provided a 15-day 

consultation and comment period to 

give the public an opportunity to 

comment on the proposed extension. 

The consultation and comment period 

ended on July 23, 2021, and WAPA 

received no comments on the proposed 

formula rate extension.

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 

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.

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 

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 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 

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

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.

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 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.

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

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

settlement for off-peak hours is 110 

percent for under-delivery and 75

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

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 Verde electricity price 

indexes, or similar alternative, for onpeak and off-peak. This pricing 

information is posted on WALC’s

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.
