SUPPLEMENTARY INFORMATION:
Rate Order No. SWPA-77 is approved and placed into effect on an interim basis for the period October 1, 2021, through September 30, 2023, for the following Southwestern Integrated System rate schedules:
Rate Schedule P-13A, Wholesale Rates for Hydro Peaking Power
Rate Schedule NFTS-13A, Wholesale Rates for Non-Federal Transmission/Interconnection Facilities Service
Rate Schedule EE-13, Wholesale Rates for Excess Energy
Decision Rationale
The Southwestern Administrator completed an annual review of the continuing adequacy of the existing rate schedules for the Integrated System. This review, as presented in the 2021 Integrated System Power Repayment Studies (PRSs), indicated the need for a 1.3 percent revenue increase to continue to satisfy cost recovery criteria. It is Southwestern practice for the Administrator to defer, on a case-by-case basis, revenue adjustments for the Integrated System if such adjustments are within plus or minus two percent of the revenue estimate based on the current Integrated System rate schedules. The deferral of a revenue adjustment (rate change) provides for rate stability and savings on the administrative costs of implementation. The Administrator determined it to be prudent to defer the increase and allow the current Integrated System rate schedules, which are set to expire September 30, 2021, to remain in effect.
To ensure that Southwestern has rate schedules in effect for collection of revenue in order to meet its repayment obligations, the Administrator has approved and placed into effect a two-year extension of the Integrated System rate schedules for the period October 1, 2021, through September 30, 2023.
The Administrator followed part 903, subpart A of title 10 of the Code of Federal Regulations (CFR), “Procedures for Public Participation in Power and Transmission Rate Adjustments and Extensions” for the extension of the rate schedules. The public was informed by notice, published in the Federal Register (86 FR 31500 (June 14, 2021)) of the proposed extension of the rate schedules and of the opportunity to provide written comments for a period of 30 days ending July 14, 2021. No comments were received.
Legal Authority
By Delegation Order No. 00-037.00B, effective November 19, 2016, the Secretary of Energy delegated: (1) The authority to develop power and transmission rates to the Southwestern Administrator; (2) the authority to confirm, approve, and place such rates into effect on an interim basis to the Deputy Secretary of Energy; and (3) the authority to confirm, approve, and place into effect on a final basis, or to remand or disapprove such rates, to the Federal Energy Regulatory Commission (FERC). By Delegation Order No. S1-DEL-S4-2021, effective February 25, 2021, the Acting Secretary of Energy also delegated the authority to confirm, approve, and place such rates into effect on an interim basis to the Under Secretary for Science (and Energy). By Redelegation Order No. S4-DEL-OE1-2021, effective March 25, 2021, the Acting Under Secretary for Science (and Energy) redelegated the authority to confirm, approve, and place such rates into effect on an interim basis to the Assistant Secretary for Electricity. And by Redelegation Order No. 00-002.10-04, effective July 8, 2020, the Assistant Secretary for Electricity further redelegated the authority to confirm, approve, and place such rates into effect on an interim basis to the Southwestern Administrator. This redelegation order, despite predating the February 2021 delegation and March 2021 redelegation, remains valid. By these delegations, and in accordance with 10 CFR 903.22(h) and 10 CFR 903.23(a), as amended, (84 FR 5347, 5350 (Feb. 21, 2019)), the Administrator may approve and extend, on an interim basis, rates previously confirmed and approved by FERC beyond the period specified by FERC.
Environmental Impact
Southwestern previously determined that the rate change actions, placed into effect on October 1, 2013 for the Integrated System fit within the class of categorically excluded actions as listed in appendix B to subpart D of 10 CFR part 1021, the Implementing Procedures and Guidelines of the National Environmental Policy Act of 1969, as amended (42 U.S.C. 4321-4347), categorical exclusions applicable to B4.3: Electric power marketing rate changes, which does not require preparation of either an environmental impact statement (EIS) or an environmental assessment (EA). On May 27, 2021, Southwestern determined that categorical exclusion B4.3 applies to the current action.
Determination Under Executive Order 12866
Southwestern has an exemption from centralized regulatory review under Executive Order 12866; accordingly, no clearance of this notice by the Office of Management and Budget is required.

ADMINISTRATOR, SOUTHWESTERN POWER ADMINISTRATION
In the matter of: Southwestern Power Administration Integrated System Rate Schedules
Rate Order No. SWPA-77
ORDER APPROVING EXTENSION OF RATE SCHEDULES ON AN INTERIM BASIS
(August 30, 2021)
Pursuant to Sections 301(b) and 302(a) and of the Department of Energy Organization Act, Public Law 42 U.S.C. 7151(b) and 7152(a), the functions of the Secretary of the Interior and the Federal Power Commission under Section 5 of the Flood Control Act of 1944, 16 U.S.C. 825s, relating to the Southwestern Power Administration (Southwestern), were transferred to, and vested in the Secretary of Energy. By Delegation Order No. 00-037.00B, effective November 19, 2016, the Secretary of Energy delegated: (1) The authority to develop power and transmission rates to the Southwestern Administrator; (2) the authority to confirm, approve, and place such rates into effect on an interim basis to the Deputy Secretary of Energy; and (3) the authority to confirm, approve, and place into effect on a final basis, or to remand or disapprove such rates, to the Federal Energy Regulatory Commission (FERC). By Delegation Order No. S1-DEL-S4-2021, effective February 25, 2021, the Acting Secretary of Energy also delegated the authority to confirm, approve, and place such rates into effect on an interim basis to the Under Secretary for Science (and Energy). By Redelegation Order No. S4-DEL-OE1-2021, effective March 25, 2021, the Acting Under Secretary for Science (and Energy) redelegated the authority to confirm, approve, and place such rates into effect on an interim basis to the Assistant Secretary for Electricity. And by Redelegation Order No. 00-002.10-04, effective July 8, 2020, the Assistant Secretary for Electricity further redelegated the authority to confirm, approve, and place such rates into effect on an interim basis to the Southwestern Administrator. This redelegation order, despite predating the February 2021 delegation and March 2021 redelegation, remains valid. By these delegations, and in accordance with 10 CFR 903.22(h) and 10 CFR 903.23(a), as amended, (84 FR 5347, 5350 (Feb. 21, 2019)), the Southwestern Administrator may approve and extend, on an interim basis, rates previously confirmed and approved by FERC beyond the period specified by FERC. Pursuant to that delegated authority, the Southwestern Administrator has issued this interim rate order.
BACKGROUND
The following rate schedules for the Integrated System were confirmed and approved on a final basis by FERC on January 9, 2014, in Docket No. EF14-1-000 (146 FERC ¶ 62,016) for the period October 1, 2013, through September 30, 2017:
Rate Schedule P-13, Wholesale Rates for Hydro Peaking Power
Rate Schedule NFTS-13, Wholesale Rates for Non-Federal Transmission/Interconnection Facilities Service
Rate Schedule EE-13, Wholesale Rates for Excess Energy
Since initial FERC approval, Southwestern added a new section within rate schedule NFTS-13 with no revenue adjustment and the revised rate schedule was designated NFTS-13A to reflect the change. The following rate schedule was placed into effect on an interim basis by the Deputy Secretary for Energy, effective January 1, 2017, and was confirmed and approved on a final basis by FERC on March 9, 2017, in Docket No. EF14-1-001 (158 FERC ¶ 62,182):
Rate Schedule NFTS-13A, Wholesale Rates for Non-Federal Transmission/Interconnection Facilities Service
A two-year extension of all Integrated System rate schedules was approved on an interim basis by the Deputy Secretary in Docket No. EF14-1-002 for the period October 1, 2017, through September 30, 2019. Subsequently, Southwestern added a new section within rate schedule P-13 with no revenue adjustment and the revised rate schedule was designated P-13A to reflect the change. The following rate schedule was placed into effect on an interim basis by the Assistant Secretary for Electricity, effective July 1, 2019, and was confirmed and approved on a final basis by FERC on August 29, 2019, in Docket No. EF14-1-003 (168 FERC ¶ 62,125):
Rate Schedule P-13A, Wholesale Rates for Hydro Peaking Power
A two-year extension of all Integrated System rate schedules was approved on an interim basis by the Assistant Secretary for Electricity for the period of October 1, 2019, through September 30, 2021.
DISCUSSION
The existing Integrated System rate schedules are based on the Southwestern 2013 Power Repayment Studies (PRSs). PRSs have been completed for the Integrated System each year since approval of the existing rate schedules. Since 2013, subsequent PRSs have indicated the need for a minimal rate increase, all within the plus or minus two percent rate adjustment threshold practice established by the Administrator on June 23, 1987. Therefore, the Administrator deferred these rate adjustments in the best interest of the government.
However, the existing rate schedules are set to expire on September 30, 2021. Consequently, Southwestern proposed to extend the existing rate schedules for a two-year period ending September 30, 2023, on an interim basis under the implementation authorities noted in 10 CFR 903.22(h) and 10 CFR 903.23(a).
Southwestern followed 10 CFR part 903, “Procedures for Public Participation in Power and Transmission Rate Adjustments and Extensions,” for the proposed extension of the rate schedules. An opportunity for customers and other interested members of the public to review and comment on the proposed extension of the rate schedules was announced by notice, published in the Federal Register on June 14, 2021 (86 FR 31500), with written comments due by July 14, 2021.
COMMENTS AND RESPONSES
Southwestern received no comments regarding the extension of the rate schedules.
AVAILABILITY OF INFORMATION
Information regarding the extension of the rate schedules is available for public review in the offices of Southwestern Power Administration, Williams Tower I, One West Third Street, Tulsa, Oklahoma 74103. The rate schedules are available on the Southwestern website at www.swpa.gov.
ADMINISTRATION'S CERTIFICATION
The 2013 Integrated System PRSs indicated that the current rate schedules will repay all costs of the Integrated System, including amortization of the power investment consistent with the provisions of Department of Energy Order No. RA 6120.2. The 2021 Integrated System PRSs indicated the need for an annual revenue increase of 1.3 percent. However, the 2021 rate adjustment falls within the Southwestern established plus or minus two percent Integrated System rate adjustment threshold practice and was deferred.
The Southwestern 2022 PRSs will determine the appropriate level of revenues needed for the next rate period. In accordance with Delegation Order No. 00-037.00B, effective November 19, 2016, and Section 5 of the Flood Control Act of 1944, the Administrator has determined that the existing rate schedules are the lowest possible rates consistent with sound business principles, and their extension is consistent with applicable law.
ENVIRONMENT
Southwestern previously determined that the rate change actions, placed into effect on October 1, 2013 for the Integrated System, fit within the class of categorically excluded actions as listed in appendix B to subpart D of 10 CFR part 1021, the Implementing Procedures and Guidelines of the National Environmental Policy Act of 1969, as amended (42 U.S.C. 4321-4347), categorical exclusions applicable to B4.3: Electric power marketing rate changes, which does not require preparation of either an environmental impact statement (EIS) or an environmental assessment (EA). On May 27, 2021, Southwestern determined that categorical exclusion B4.3 applies to the current action.
ADMINISTRATIVE PROCEDURES
Under the Administrative Procedure Act (5 U.S.C. 553(d)), publication or service of a substantive rule must be made not less than 30 days before its effective date, except (1) a substantive rule that grants or recognizes an exemption or relieves a restriction; (2) interpretative rules and statements of policy; or (3) as otherwise provided by the agency for good cause found and published with the rule. The Administrator finds good cause to waive the 30-day delay in the effective date of this action as unnecessary for the following reasons: (1) This is an extension of rates previously approved by FERC, pursuant to 10 CFR 903.23(a); (2) there are no substantive changes, as the existing rate schedules and anticipated revenues remain the same; and (3) the Administrator provided notice and opportunity for public comment more than 30 days prior to the effective date of the rate extension and received no comments.
ORDER
In view of the foregoing, and pursuant to delegated authority from the Secretary of Energy, I hereby extend on an interim basis, for the period of two years, effective October 1, 2021, through September 30, 2023, the current Integrated System rate schedules:
Rate Schedule P-13A, Wholesale Rates for Hydro Peaking Power
Rate Schedule NFTS-13A, Wholesale Rates for Non-Federal Transmission/Interconnection Facilities Service
Rate Schedule EE-13, Wholesale Rates for Excess Energy

Subject to Southwestern's approval of the ability of such resources or third parties to meet Southwestern's technical and operational requirements for provision of such Ancillary Services, the Customer may change the Ancillary Services which it takes from Southwestern and/or from other sources at the beginning of any month upon the greater of 60 days notice or upon completion of any necessary equipment modifications necessary to accommodate such change; Provided, That, if the Customer chooses not to take Regulation and Frequency Response Service, which includes the associated Regulation Purchased Adder, the Customer must pursue these services from a different host Balancing Authority; thereby moving all metered loads and resources from Southwestern's Balancing Authority Area to the Balancing Authority Area of the new host Balancing Authority. Until such time as that meter reconfiguration is accomplished, the Customer will be charged for the Regulation and Frequency Response Service and applicable Adder then in effect. The Customer must notify Southwestern by July 1 of this choice, to be effective the subsequent calendar year.
2.4.5. Regulation Purchased Adder
Southwestern has determined the amount of energy used from storage to provide Regulation and Frequency Response Service in order to meet Southwestern's Balancing Authority Area requirements. The replacement value of such energy used shall be recovered through the Regulation Purchased Adder. The Regulation Purchased Adder during the time period of January 1 through December 31 of the current calendar year is based on the average annual use of energy from storage for Regulation and Frequency Response Service and Southwestern's estimated purchased power price for the corresponding year from the most currently approved Power Repayment Studies.
The average annual use of energy from storage for Regulation and Frequency Response Service is based on Southwestern studies.
The Regulation Purchased Adder will be phased in over a period of four (4) years as follows:
| Year | Regulation purchased adder for the incremental replacement value of energy used from storage |
|---|---|
| 2014 | 1/4 of the average annual use of energy from storage × 2014 Purchased Power price. |
| 2015 | 1/2 of the average annual use of energy from storage × 2015 Purchased Power price. |
| 2016 | 3/4 of the average annual use of energy from storage × 2016 Purchased Power price. |
| 2017 and thereafter | The total average annual use of energy from storage × the applicable Purchased Power price. |
2.4.5.1. Applicability of Regulation Purchased Adder
The replacement value of the estimated annual use of energy from storage for Regulation and Frequency Response Service shall be recovered by Customers located within Southwestern's Balancing Authority Area on a non-coincident peak ratio share basis, divided into twelve equal monthly payments, in accordance with the formula in Section 2.4.5.2.
If the Regulation Purchased Adder is determined and applied under Southwestern's Rate Schedule NFTS-13A, then it shall not be applied here.
2.4.5.2. Procedure for Determining Regulation Purchased Adder
Unless otherwise specified by contract, the Regulation Purchased Adder for an individual Customer shall be based on the following formula rate, calculated to include the replacement value of the estimated annual use of energy from storage by Southwestern for Regulation and Frequency Response Service.
RPA = The Regulation Purchased Adder for an individual Customer per month, which is as follows:
[(LCustomer ÷ LTotal) × RPTotal] ÷ 12
with the factors defined as follows:
LCustomer = The sum in MW of the following three factors:
(1) The Customer's highest metered load plus generation used to serve the Customer's load that is accounted for through a reduction in the Customer's metered load (referred to as `generation behind the meter') during the previous calendar year, and
(2) The Customer's highest rate of Scheduled Exports during the previous calendar year, and
Scheduled Exports and Scheduled Imports are transactions, such as sales and purchases respectively, which are in addition to a Customer's metered load that contribute to Southwestern's Balancing Authority Area need for regulation.
(3) The Customer's highest rate of Scheduled Imports 2 during the previous calendar year.
LTotal = The sum of all L Customer factors for all Customers that were inside Southwestern's Balancing Authority Area at the beginning of the previous calendar year in MW.
RPTotal = The “net” cost in dollars and cents based on Southwestern's estimated purchased power price for the corresponding year from the most currently approved Power Repayment Studies multiplied by the average annual use of energy from storage, as provided for in the table in Section 2.4.5, to support Southwestern's ability to regulate within its Balancing Authority Area. The “net” cost in dollars and cents shall be adjusted by subtracting the product of the quantity of such average annual use of energy from storage in MWh and Southwestern's highest rate in dollars per MWh for Supplemental Peaking Energy during the previous calendar year.
For Customers that have aggregated their load, resources, and scheduling into a single node by contract within Southwestern's Balancing Authority Area, the individual Customer's respective Regulation Purchased Adder shall be that Customer's ratio share of the Regulation Purchased Adder established for the node. Such ratio share shall be determined for the Customer on a non-coincident basis and shall be calculated for the Customer from their highest metered load plus generation behind the meter.
2.4.6. Energy Imbalance Service Limitations
Energy Imbalance Service primarily applies to deliveries of power and energy which are required to satisfy a Customer's load. As Hydro Peaking Power and associated energy are limited by contract, the Energy Imbalance Service bandwidth specified for Non-Federal Transmission Service does not apply to deliveries of Hydro Peaking Power, and therefore Energy Imbalance Service is not charged on such deliveries. Customers who consume a capacity of Hydro Peaking Power greater than their Peaking Contract Demand may be subject to a Capacity Overrun Penalty.
3. Hydro Peaking Power Penalties, Terms, and Conditions
3.1. Capacity Overrun Penalty
3.1.1. Penalty Charge for Capacity Overrun
For each hour during which Hydro Peaking Power was provided at a rate greater than that to which the Customer is entitled, the Customer will be charged a Capacity Overrun Penalty at the following rates:
| Months associated with charge | Rate per kilowatt |
|---|---|
| March, April, May, October, November, December | $0.15 |
| January, February, June, July, August, September | 0.30 |
3.1.2. Applicability of Capacity Overrun Penalty
Customers which have loads within Southwestern's Balancing Authority Area are obligated by contract to provide resources, over and above the Hydro Peaking Power and associated energy purchased from Southwestern, sufficient to meet their loads. A Capacity Overrun Penalty shall be applied only when the formulas provided in Customers' respective Power Sales Contracts indicate an overrun on Hydro Peaking Power, and investigation determines that all resources, both firm and non-firm, which were available at the time of the apparent overrun were insufficient to meet the Customer's load.
3.2. Energy Overrun Penalty
3.2.1. Penalty Charge for Energy Overrun
$0.1034 per kilowatthour for each kilowatthour of overrun.
3.2.2. Applicability of Energy Overrun Penalty
By contract, the Customer is subject to limitations on the maximum amounts of Peaking Energy which may be scheduled under the Customer's Power Sales Contract. When the Customer schedules an amount in excess of such maximum amounts, such Customer is subject to the Energy Overrun Penalty.
3.3. Power Factor Penalty
3.3.1. Requirements Related to Power Factor
Any Customer served from facilities owned by or available by contract to Southwestern will be required to maintain a power factor of not less than 95 percent and will be subject to the following provisions.
3.3.2. Determination of Power Factor
The power factor will be determined for all Demand Periods and shall be calculated under the formula:
with the factors defined as follows:
PF = The power factor for any Demand Period of the month.
kWh = The total quantity of energy which is delivered during such Demand Period to the point of delivery or interconnection in accordance with Section 3.3.4.
rkVAh = The total quantity of reactive kilovolt-ampere-hours (kVARs) delivered during such Demand Period to the point of delivery or interconnection in accordance with Section 3.3.4.
3.3.3. Penalty Charge for Power Factor
The Customer shall be assessed a penalty for all Demand Periods of a month where the power factor is less than 95 percent lagging. For any Demand Period during a particular month such penalty shall be in accordance with the following formula:
C = D × (0.95−LPF) × $0.10
with the factors defined as follows:
C = The charge in dollars to be assessed for any particular Demand Period of such month that the determination of power factor “PF” is calculated to be less than 95 percent lagging.
D = The Customer's demand in kilowatts at the point of delivery for such Demand Period in which a low power factor was calculated.
LPF = The lagging power factor, if any, determined by the formula “PF” for such Demand Period.
If C is negative, then C = zero (0).
3.3.4. Applicability of Power Factor Penalty
The Power Factor Penalty is applicable to radial interconnections with the System of Southwestern. The total Power Factor Penalty for any month shall be the sum of all charges “C” for all Demand Periods of such month. No penalty is assessed for leading power factor. Southwestern, in its sole judgment and at its sole option, may determine whether power factor calculations should be applied to (i) a single physical point of delivery, (ii) a combination of physical points of delivery where a Customer has a single, electrically integrated load, (iii) or interconnections. The general criteria for such decision shall be that, given the configuration of the Customer's and Southwestern's systems, Southwestern will determine, in its sole judgment and at its sole option, whether the power factor calculation more accurately assesses the detrimental impact on Southwestern's system when the above formula is calculated for a single physical point of delivery, a combination of physical points of delivery, or for an interconnection as specified by an Interconnection Agreement.
Southwestern, at its sole option, may reduce or waive Power Factor Penalties when, in Southwestern's sole judgment, low power factor conditions were not detrimental to the System of Southwestern due to particular loading and voltage conditions at the time the power factor dropped below 95 percent lagging.

Supersedes Rate Schedule P-13.
** Extended through September 30, 2023, by approval of Rate Order No. SWPA-77 by the Administrator, Southwestern Power Administration.
The Regulation Purchased Adder will be phased in over a period of four (4) years as follows:
| Year | Regulation Purchased Adder for the incremental replacement value of energy used from storage |
|---|---|
| 2014 | 1/4 of the average annual use of energy from storage × 2014 Purchased Power price. |
| 2015 | 1/2 of the average annual use of energy from storage × 2015 Purchased Power price. |
| 2016 | 3/4 of the average annual use of energy from storage × 2016 Purchased Power price. |
| 2017 and thereafter | The total average annual use of energy from storage × the applicable Purchased Power price. |
2.6.5.1. Applicability of Regulation Purchased Adder
The replacement value of the estimated annual use of energy from storage for Regulation and Frequency Response Service shall be recovered by Customers located within Southwestern's Balancing Authority Area on a non-coincident peak ratio share basis, divided into twelve equal monthly payments, in accordance with the formula in Section 2.6.5.2.
If the Regulation Purchased Adder is determined and applied under Southwestern's Rate Schedule P-13, then it shall not be applied here.
2.6.5.2. Procedure for Determining Regulation Purchased Adder
Unless otherwise specified by contract, the Regulation Purchased Adder for an individual Customer shall be based on the following formula rate, calculated to include the replacement value of the estimated annual use of energy from storage by Southwestern for Regulation and Frequency Response Service.
RPA = The Regulation Purchased Adder for an individual Customer per month, which is as follows:
[(LCustomer ÷ L Total) × RPTotal] ÷ 12
with the factors defined as follows:
LCustomer = The sum in MW of the following three factors:
(1) The Customer's highest metered load plus generation used to serve the Customer's load that is accounted for through a reduction in the Customer's metered load (referred to as `generation behind the meter') during the previous calendar year, and
(2) The Customer's highest rate of Scheduled Exports during the previous calendar year, and
Scheduled Exports and Scheduled Imports are transactions, such as sales and purchases respectively, which are in addition to a Customer's metered load that contribute to Southwestern's Balancing Authority Area need for regulation.
(3) The Customer's highest rate of Scheduled Imports 2 during the previous calendar year.
LTotal = The sum of all L Customer factors for all Customers that were inside Southwestern's Balancing Authority Area at the beginning of the previous calendar year in MW.
RPTotal = The “net” cost in dollars and cents based on Southwestern's estimated purchased power price for the corresponding year from the most currently approved Power Repayment Studies multiplied by the average annual use of energy from storage, as provided for in the table in Section 2.6.5, to support Southwestern's ability to regulate within its Balancing Authority Area. The “net” cost in dollars and cents shall be adjusted by subtracting the product of the quantity of such average annual use of energy from storage in MWh and Southwestern's highest rate in dollars per MWh for Supplemental Peaking Energy during the previous calendar year.
For Customers that have aggregated their load, resources, and scheduling into a single node by contract within Southwestern's Balancing Authority Area, the individual Customer's respective Regulation Purchased Adder shall be that Customer's ratio share of the Regulation Purchased Adder established for the node. Such ratio share shall be determined for the Customer on a non-coincident basis and shall be calculated for the Customer from their highest metered load plus generation behind the meter.
2.6.6. Energy Imbalance Service Limitations
Energy Imbalance Service is authorized for use only within a bandwidth of ☐1.5 percent of the actual requirements of the load at a particular point of delivery, for any hour, compared to the resources scheduled to meet such load during such hour. Deviations which are greater than ☐1.5 percent, but which are less than ☐2,000 kilowatts, are considered to be within the authorized bandwidth. Deviations outside the authorized bandwidth are subject to a Capacity Overrun Penalty.
Energy delivered or received within the authorized bandwidth for this service is accounted for as an inadvertent flow and will be netted against flows in the future. The inadvertent flow in any given hour will only be offset with the flows in the corresponding hour of a day in the same category. Unless otherwise specified by contract, the two categories of days are weekdays and weekend days/North American Electric Reliability Corporation holidays, and this process will result in a separate inadvertent accumulation for each hour of the two categories of days. The hourly accumulations in the current month will be added to the hourly inadvertent balances from the previous month, resulting in a month-end balance for each hour.
The Customer is required to adjust the scheduling of resources in such a way as to reduce the accumulation towards zero. It is recognized that the inadvertent hourly flows can be both negative and positive, and that offsetting flows should deter a significant accumulation of inadvertent. Unless otherwise specified by contract, in the event any hourly month-end balance exceeds 12 MWhs, the excess will be subject to Section 3.1 or Section 3.2 of this Rate Schedule, depending on the direction of the accumulation.
3. Non-Federal Transmission/Interconnection Facilities Service Penalties, Terms, and Conditions
3.1. Capacity Overrun Penalty
3.1.1. Penalty Charge for Capacity Overrun
For each hour during which energy flows outside the authorized bandwidth, the Customer will be obliged to purchase such energy at the following rates:
| Months associated with charge | Rate per kilowatt |
|---|---|
| March, April, May, October, November, December | $0.15 |
| January, February, June, July, August, September | 0.30 |
3.1.2. Applicability of Capacity Overrun Penalty
Customers who receive deliveries within Southwestern's Balancing Authority Area are obligated to provide resources sufficient to meet their loads. Such obligation is not related to the amount of transmission capacity that such Customers may have reserved for transmission service to a particular load. In the event that a Customer underschedules its resources to serve its load, resulting in a difference between resources and actual metered load (adjusted for transformer losses as applicable) outside the authorized bandwidth for Energy Imbalance Service for any hour, then such Customer is subject to the Capacity Overrun Penalty.
3.2. Unauthorized Use of Energy Imbalance Service by Overscheduling of Resources
In the event that a Customer schedules greater resources than are needed to serve its load, such that energy flows at rates beyond the authorized bandwidth for the use of Energy Imbalance Service, Southwestern retains such energy at no cost to Southwestern and with no obligation to return such energy.
3.3. Power Factor Penalty
3.3.1. Requirements Related to Power Factor
Any Customer served from facilities owned by or available by contract to Southwestern will be required to maintain a power factor of not less than 95 percent and will be subject to the following provisions.
3.3.2. Determination of Power Factor
The power factor will be determined for all Demand Periods and shall be calculated under the formula:
with the factors defined as follows:
PF = The power factor for any Demand Period of the month.
kWh = The total quantity of energy which is delivered during such Demand Period to the point of delivery or interconnection in accordance with Section 3.3.4.
rkVAh = The total quantity of reactive kilovolt-ampere-hours (kVARs) delivered during such Demand Period to the point of delivery or interconnection in accordance with Section 3.3.4.
3.3.3. Penalty Charge for Power Factor
The Customer shall be assessed a penalty for all Demand Periods of a month where the power factor is less than 95 percent lagging. For any Demand Period during a particular month such penalty shall be in accordance with the following formula:
C = D × (0.95 − LPF) × $0.10
with the factors defined as follows:
C = The charge in dollars to be assessed for any particular Demand Period of such month that the determination of power factor “PF” is calculated to be less than 95 percent lagging.
D = The Customer's demand in kilowatts at the point of delivery for such Demand Period in which a low power factor was calculated.
LPF = The lagging power factor, if any, determined by the formula “PF” for such Demand Period.
If C is negative, then C = zero (0).
3.3.4. Applicability of Power Factor Penalty
The Power Factor Penalty is applicable to radial interconnections with the System of Southwestern. The total Power Factor Penalty for any month shall be the sum of all charges “C” for all Demand Periods of such month. No penalty is assessed for leading power factor. Southwestern, in its sole judgment and at its sole option, may determine whether power factor calculations should be applied to (i) a single physical point of delivery, (ii) a combination of physical points of delivery where a Customer has a single, electrically integrated load, (iii) or interconnections. The general criteria for such decision shall be that, given the configuration of the Customer's and Southwestern's systems, Southwestern will determine, in its sole judgment and at its sole option, whether the power factor calculation more accurately assesses the detrimental impact on Southwestern's system when the above formula is calculated for a single physical point of delivery, a combination of physical points of delivery, or for an interconnection as specified by an Interconnection Agreement.
Southwestern, at its sole option, may reduce or waive Power Factor Penalties when, in Southwestern's sole judgment, low power factor conditions were not detrimental to the System of Southwestern due to particular loading and voltage conditions at the time the power factor dropped below 95 percent lagging.
4. Non-Federal Transmission/Interconnection Facilities Service Miscellaneous Rates, Terms, and Conditions
4.1. Real Power Losses
Customers are required to self-provide all Real Power Losses for non-Federal energy transmitted by Southwestern on behalf of such Customers under the provisions detailed below.
Real Power Losses are computed as four (4) percent of the total amount of non-Federal energy transmitted by Southwestern. The Customer's monthly Real Power Losses are computed each month on a megawatthour basis as follows:
ML = 0.04 × NFE
with the factors defined as follows:
ML = The total monthly loss energy, rounded to the nearest megawatthour, to be scheduled by a Customer for receipt by Southwestern for Real Power Losses associated with non-Federal energy transmitted on behalf of such Customer; and
NFE = The amount of non-Federal energy that was transmitted by Southwestern on behalf of a Customer during a particular month.
The Customer must schedule or cause to be scheduled to Southwestern, Real Power Losses for which it is responsible subject to the following conditions:
4.1.1. The Customer shall schedule and deliver Real Power Losses back to Southwestern during the second month after they were incurred by Southwestern in the transmission of the Customer's non-Federal power and energy over the System of Southwestern unless such Customer has accounted for Real Power Losses as part of a metering arrangement with Southwestern.
4.1.2. On or before the twentieth day of each month, Southwestern shall determine the amount of non-Federal loss energy it provided on behalf of the Customer during the previous month and provide a written schedule to the Customer setting forth hour-by-hour the quantities of non-Federal energy to be delivered to Southwestern as losses during the next month.
4.1.3. Real Power Losses not delivered to Southwestern by the Customer, according to the schedule provided, during the month in which such losses are due shall be billed by Southwestern to the Customer to adjust the end-of-month loss energy balance to zero (0) megawatthours and the Customer shall be obliged to purchase such energy at the following rates:
| Months associated with charge | Rate per kilowatthour |
|---|---|
| March, April, May, October, November, December | $0.15 |
| January, February, June, July, August, September | 0.30 |
4.1.4. Real Power Losses delivered to Southwestern by the Customer in excess of the losses due during the month shall be purchased by Southwestern from the Customer at a rate per megawatthour equal to Southwestern's rate per megawatthour for Supplemental Peaking Energy, as set forth in Southwestern's then-effective Rate Schedule for Hydro Peaking Power to adjust such hourly end-of-month loss energy balance to zero (0) megawatthours.
