Western Area Power Administration


Loveland Area Projects--Rate Order No. WAPA-219

AGENCY: Western Area Power Administration, DOE.

ACTION: Notice of rate order concerning transmission and ancillary 
services formula rates.

-----------------------------------------------------------------------

SUMMARY: The formula rates for the Rocky Mountain region's (RMR) 
Loveland Area Projects (LAP) transmission and ancillary services for 
RMR's costs to be recovered under the Southwest Power Pool's (SPP) Open 
Access Transmission Tariff (Tariff) should RMR decide to become a 
member of SPP, have been confirmed, approved, and placed into effect on 
an interim basis (Provisional Formula Rates). If RMR decides to become 
a member of SPP, these new formula rates under Rate Schedules LAPT-ATRR 
(transmission), LAPT-DCTIE-IMEU (incremental market efficiency use 
share), and LAPT-AS1 (scheduling, system control, and dispatch) will 
supersede the existing formula rates for transmission and ancillary 
services under Rate Schedules L-NT1, L-FPT1, L-NFPT1, L-NFJDT, L-UU1, 
L-AS1, L-AS2, L-AS3, L-AS4, L-AS5, L-AS6, L-AS7, and L-AS9, which 
expire on September 30, 2026.

DATES: The Provisional Formula Rates under Rate Schedules LAPT-ATRR, 
LAPT-DCTIE-IMEU, and LAPT-AS1 are effective on the first day of the 
first full billing period beginning on the later of the following 
events: (1) when RMR officially becomes a member of, and transfers 
functional control of LAP transmission facilities to, SPP; or (2) the 
go-live date of the expansion of the SPP Regional Transmission 
Organization into the Western Interconnection (scheduled for April 1, 
2026, as of the date of this Rate Order). RMR will provide notification 
of the effective date of the Provisional Formula Rates on its Rates and 
Open Access Same-Time Information System websites. These Provisional 
Formula Rates will remain in effect through March 31, 2031, pending 
confirmation and approval by the Federal Energy Regulatory Commission 
(FERC) on a final basis or until superseded. If RMR does not become a 
member of SPP, these rates will be canceled and the existing formula 
rates will remain in effect.

SUPPLEMENTARY INFORMATION: On September 16, 2024, FERC confirmed and 
approved Rate Schedules L-NT1 (network), L-FPT1 (firm point-to-point), 
L-NFPT1 (non-firm point-to-point), L-NFJDT (joint dispatch 
transmission), L-UU1 (unreserved use), L-AS1 (scheduling and dispatch), 
L-AS2 (reactive supply and voltage control support), L-AS3 
(regulation), L-AS4 (energy imbalance), L-AS5 (spinning reserves), L-
AS6 (supplemental reserves), L-AS7 (BA real power losses), and L-AS9 
(generator imbalance) under Rate Order No. WAPA-214 on a final basis 
through September 30, 2026.\1\ Western Area Power Administration (WAPA) 
published a Federal Register notice (Proposed FRN) on December 27, 2024 
(89 FR 105564), proposing new formula rates for LAP transmission and 
ancillary services in order for RMR to recover its costs under the SPP 
Tariff should RMR decide to become a member of SPP. The Proposed FRN 
also initiated a 90-day public consultation and comment period and set 
forth the date of the virtual public information and public comment 
forums. Consistent with RMR's current transmission and ancillary 
services formula rates, RMR will continue to use a formula-based 
methodology. RMR will annually update the data used in the rate formula 
calculations in accordance with the Formula Rate Implementation 
Protocols (Protocols).

interested parties in the rate process:
    1. On December 27, 2024, a FRN (89 FR 105564) (Proposed FRN) 
announced the proposed formula rates and initiated a 90-day public 
consultation and comment period.
    2. On January 2, 2025, RMR notified customers and interested 
parties of the proposed rates and provided a copy of the published 
Proposed FRN.
    3. On February 19, 2025, RMR held a virtual public information 
forum where RMR's representatives explained the proposed formula rates, 
answered questions, and gave notice that more information was available 
in the Customer Rate Brochure.
    4. On February 19, 2025, RMR held a virtual public comment forum to 
provide an opportunity for customers and other interested parties to 
comment for the record.
    5. RMR posted information about the rate process on two public 
websites. RMR's Rates website located at www.wapa.gov/about-wapa/regions/rm/rm-rates/2026-rate-adjustment-rto-trans-and-anc-svcs, and 
RMR's OASIS website located at www.oasis.oati.com/LAPT/index.html.
    6. During the 90-day consultation and comment period, which ended 
on March 27, 2025, RMR received no oral comment submissions and no 
written comment letters.

Transmission and Ancillary Services Rate Discussion

    On April 28, 2023, WAPA published a FRN titled ``Recommendation for 
the Western Area Power Administration's Rocky Mountain Region and 
Colorado River Storage Project Management Center to Pursue Final 
Negotiations Regarding Membership in the Southwest Power Pool Regional 
Transmission Organization, and for the Upper Great Plains Region to 
Expand its Participation'' (88 FR 26298). On June 4, 2024, SPP 
submitted revisions to its Tariff, Bylaws, and Membership Agreement to 
expand the SPP RTO into the Western Interconnection to FERC.\3\ On 
March 20, 2025, FERC accepted, subject to condition and further 
compliance filing, SPP's proposed Tariff, Bylaws, and Membership 
Agreement revisions. Subject to further approval by the Administrator,

2024).
---------------------------------------------------------------------------

    RMR's membership will include RMR becoming a Transmission Owner 
member of SPP and SPP assuming the BA responsibilities for RMR's 
Western Area Colorado Missouri (WACM) BAA. WAPA will transfer 
functional control of eligible LAP transmission facilities to SPP (LAP 
has transmission facilities in both the Eastern and Western 
Interconnections separated by the Sidney DC Tie). Subsequently, LAP 
transmission and ancillary services and WACM BA ancillary services will 
no longer be available under WAPA's Tariff, and RMR's BA contracts and 
the existing transmission and ancillary services rate schedules, 
specifically L-NT1, L-FPT1, L-NFPT1, L-NFJDT, L-UU1, L-AS1, L-AS2, L-
AS3, L-AS4, L-AS5, L-AS6, L-AS7, and L-AS9, will no longer be 
applicable.
    LAP transmission and ancillary services will be provided under the 
SPP Tariff by SPP as the transmission service provider. Accordingly, 
RMR has developed new formula rate designs/rate schedules for specific 
costs to be recovered under the SPP Tariff. For each formula rate, the 
appropriate data will be submitted to SPP in standard formula rate 
templates in accordance with SPP's Tariff Attachment H. RMR will 
identify any portion of its ATRR eligible for recovery under SPP's 
Tariff Schedule 9 and Schedule 11 in these formula rate templates. 
RMR's revenue requirements are added to the annual revenue requirements 
of other transmission owners in the multi-owner SPP pricing Zone 104, 
also identified as the Loveland Area Projects Zone (LAPZ), for 
transmission service billed by SPP within the LAPZ. RMR's revenue 
requirements under these rates also impact other costs for transmission 
service within the broader SPP footprint.
    For each formula rate, RMR will true up its estimated costs with 
actual costs each year. If RMR collects more revenue than its actual 
net revenue requirement or IMEU Share, RMR will return this revenue 
through a credit against a revenue requirement or IMEU Share in a 
subsequent year. Actual revenues that are less than the net revenue 
requirement or IMEU Share would likewise be recovered in a subsequent 
year. The true-up procedure will ensure that RMR will recover no more 
and no less than the actual transmission costs for the year.
    Data used in the annual recalculation of the formula rates each 
year will be made available for review and comment as described in the 
Formula Rate Implementation Protocols (Protocols). These Protocols 
ensure that interested parties are aware of the data used to calculate 
the formula rates and are provided the opportunity to comment

[[Page 30927]]

before the costs are collected through the formula rates.
    The formula rate templates and the Protocols will be posted on the 
applicable SPP website and on RMR's OASIS website.

Formula Rate for LAP Annual Transmission Revenue Requirement--Rate 
Schedule LAPT-ATRR

    RMR will use a formula-based rate methodology to calculate its 
ATRR. The ATRR is derived by annualizing LAP transmission investments 
that meet the Transmission Facility criteria as identified in 
Attachment AI to SPP's Tariff and adding transmission-related annual 
costs, which include interest, O&M, administrative and general 
expenses, and depreciation. The annual costs will be reduced by 
applicable revenue credits received by RMR under the SPP Tariff. RMR 
will recover transmission-related expenses and investments on a 
forward-looking basis by using projections to estimate transmission 
costs for the upcoming rate year, with a true-up of incurred costs in a 
subsequent year. RMR will true-up the cost estimates it used in the 
calculation of its FY 2025 and FY 2026 transmission rates that were in 
place prior to joining SPP when calculating these future true-ups.
    RMR will provide its overall ATRR as separate subtotals to 
distinguish LAP transmission facilities between Eastern 
Interconnection, Western Interconnection, Sidney DC Tie, and other SPP 
Zones. SPP will utilize these ATRR subtotals, along with zonal and 
regional load and other applicable information, to calculate the 
applicable charges and revenue distribution for SPP transmission 
service under the SPP Tariff.

Formula Rate for Sidney DC Tie Incremental Market Efficiency Use 
Share--Rate Schedule LAPT-DCTIE-IMEU

    SPP's Incremental MEU Charge compensates each West DC Tie 
Transmission Owner for the expected loss of life of that owner's West 
DC Tie facility due to increased utilization of the West DC Ties by the 
Integrated Marketplace.
    To simplify the calculation of the Sidney DC Tie IMEU Share and 
provide a consistent forward-looking amount, RMR will use a loss-of-
life factor for each eligible group of Sidney DC Tie equipment due to 
expected market operation impacts, and provide a levelized annual 
estimate to SPP. The loss-of-life calculations are based upon impact 
metrics directly related to the increased market use for each of the 
Sidney DC Tie equipment groups eligible for cost recovery. The IMEU 
Share calculations are based upon the change in the estimated 
depreciation expense due to the loss of life predicted for each group 
of Sidney DC Tie equipment. Cost estimates are calculated on a forward-
looking basis by using projections to determine costs for the upcoming 
rate year, with a true-up of incurred costs in a subsequent year. 
Revenue received from SPP for RMR's Sidney DC Tie IMEU Share will be 
credited against the Sidney DC Tie portion of the LAP ATRR previously 
described.

Formula Rate for Scheduling, System Control, and Dispatch Service--Rate 
Schedule LAPT-AS1

    Scheduling, System Control, and Dispatch (SSCD) Service is required 
to operate a Transmission Owner's SPP Tariff facilities and schedule 
movement of power through, out of, within, or into one or both of the 
SPP BAAs and certain parts of the transmission system not located 
within a SPP BAA. These functions are conducted by the RMR Operations 
staff on behalf of the LAP and Colorado River Storage Project (CRSP) 
Transmission Owners. RMR will use a formula-based rate methodology to 
calculate its annual revenue requirement (ARR) for SSCD Service. RMR's 
overall ARR for SSCD Service is allocated between RMR and the CRSP 
region. RMR's transmission portion of its allocation of the SSCD ARR 
will be collected under Rate Schedule LAPT-AS1 and the CRSP region's 
allocation of the SSCD ARR will be collected by the CRSP region under 
their applicable rate(s). SPP will use RMR's transmission portion of 
its allocation of the SSCD ARR to determine the regional SPP Schedule 1 
rate and revenue distribution for SPP through-and-out transactions and 
to determine the zonal SPP Schedule 1 rate and revenue distribution for 
the appropriate Zones under the SPP Tariff.
    RMR's overall SSCD Service ARR is derived by calculating RMR's 
applicable annual costs associated with the provision of SSCD Service, 
including O&M, administrative and general expenses, interest, and 
depreciation. Estimates are calculated on a forward-looking basis by 
using projections to determine costs associated with SSCD Service for 
the upcoming rate year, with a true-up of incurred costs in a 
subsequent year. RMR's portion of its allocation of the SSCD ARR will 
be reduced by any applicable revenue received by RMR under the SPP 
Tariff.

Formula Rate Implementation Protocols

    For transmission and ancillary services provided under the SPP 
Tariff, RMR will provide information relating to RMR's rate 
implementation and annual update procedures and timelines in a 
``Formula Rate Implementation Protocols'' document. The Protocols, 
together with the above-mentioned formula rate templates, comprise the 
Formula Rates that will be submitted to SPP to be incorporated in the 
SPP Tariff. All relevant information pertaining to RMR's annual 
updates, customer notifications and review periods, and meeting 
requirements are contained in the Protocols. These notifications, 
review periods, and meetings ensure that interested parties are aware 
of the data used to calculate the formula rates and are provided the 
opportunity to comment before the costs are collected through the 
formula rates.

Certification of Rates

    I have certified that the Provisional Formula Rates for Loveland 
Area Projects transmission and ancillary service under Rate Schedules 
LAPT-ATRR, LAPT-DCTIE-IMEU, and LAPT-AS1 are the lowest possible rates, 
consistent with sound business principles. The Provisional Formula 
Rates were developed following administrative policies and applicable 
laws.

Availability of Information

    Information used by RMR to develop the Provisional Formula Rates is 
available for inspection and copying at the Rocky Mountain Regional 
Office, 5555 East Crossroads Boulevard, Loveland, CO. Many of these 
documents are also available on RMR's Rates website previously listed.

Annual Transmission Revenue Requirement for Transmission Service

(Approved Under Rate Order No. WAPA-219)

Effective

    The first day of the first full billing period beginning on the 
later of the following events: (1) when the Western Area Power 
Administration--Rocky Mountain region (WAPA-RMR) officially becomes a 
member of, and transfers functional control of Loveland Area Projects 
(LAP) transmission facilities to, the Southwest Power Pool (SPP); or 
(2) the go-live date of the expansion of the SPP Regional Transmission 
Organization (RTO) into the Western Interconnection (scheduled for 
April 1, 2026, as of the date of the approved Rate Order) and extending 
through March 31, 2031, or until superseded by another rate schedule, 
whichever occurs earlier. Notification of the actual effective date 
will be posted on WAPA-RMR's Rates website and on WAPA-RMR's Open 
Access Same-Time Information System (OASIS) website.

Applicable

    WAPA-RMR's formula based Annual Transmission Revenue Requirement 
(ATRR) for its eligible transmission-related facilities included under 
the SPP Open Access Transmission Tariff (Tariff) will be separated 
between (1) LAP's Western Interconnection transmission facilities, (2) 
LAP's Eastern Interconnection transmission facilities, (3) LAP's Sidney 
Direct Current (DC) Tie facilities, and (4) LAP's transmission 
facilities determined to be in other SPP RTO transmission pricing 
zones. Each ATRR subtotal will be calculated using the formula outlined 
below.

Formula Rate

Define:
A = Operation & Maintenance Expense allocated to transmission ($)
B = Administrative and General Expense allocated to transmission ($)
C = Depreciation Expense allocated to transmission ($)
D = Interest Expense allocated to transmission ($)
E = Applicable ratio share of plant for LAP's Western Interconnection 
transmission facilities, Eastern Interconnection transmission 
facilities, Sidney DC Tie facilities, and LAP transmission facilities 
determined to be in other SPP RTO transmission pricing zones (%)
F = Revenue Credits--Scheduling, System Control, and Dispatch service 
associated with each specific ATRR subtotal ($)
G = Revenue Credits associated with each specific ATRR subtotal ($)
H = Prior Period True-up associated with each specific ATRR subtotal 
($)
ATRR Subtotals = ((A + B + C + D) * E)--F--G + H
Total ATRR = Sum of all ATRR Subtotals

    Note: WAPA-RMR will identify any portion(s) of the ATRR eligible 
for recovery under SPP Schedule 9 and Schedule 11 pursuant to the SPP 
Tariff in its Rate Formula Template submitted under Attachment H of the 
SPP Tariff.
    A recalculated ATRR will go into effect every January 1 based on 
the above formula and updated financial data. WAPA-RMR will annually 
notify SPP and make data and information available to interested 
parties for review and comment related to the recalculated ATRR on or 
shortly after September 1 of the preceding year. This data and 
information will be posted on the applicable SPP website and on WAPA-
RMR's OASIS website.

through March 31, 2031, or until superseded by another rate schedule, 
whichever occurs earlier. Notification of the actual effective date 
will be posted on WAPA-RMR's Rates website and on WAPA-RMR's Open 
Access Same-Time Information System (OASIS) website.

Applicable

    The Incremental Market Efficiency Use (IMEU) accounts for each 
Western Interconnection Direct Current (West DC) Tie Transmission 
Owner's expected loss of life of that owner's West DC Tie facilities 
due to increased utilization of the West DC Ties by the SPP Integrated 
Marketplace. WAPA-RMR's IMEU Share for the Sidney DC Tie will be 
calculated using the formula outlined below.

Formula Rate

Define (for each Group of IMEU eligible Sidney DC Tie equipment):
A = Sidney DC Tie Gross Plant Impacted by IMEU ($)
B = Average Service Life of Gross Plant Impacted by IMEU
C = Average Service Life Depreciation Rate of Gross Plant Impacted by 
IMEU (%)
D = Loss of Service Life Due to Market Use (%)
E = Decreased Average Service Life Depreciation Rate of Gross Plant 
Impacted by IMEU (%)
IMEU Share for each Group = (E-C)*A, where 1/B=C, and where 1/(B*(1-
D))=E
F = Prior period true-up ($)
Total IMEU Share = Sum of IMEU Share for all Groups + F

    A recalculated IMEU Share will go into effect every January 1 based 
on the above formula and updated financial/criteria data. WAPA-RMR will 
annually notify SPP and make data and information available to 
interested parties for review and comment related to the recalculated 
IMEU Share on or shortly after September 1 of the preceding year. This 
data and information will be posted on the applicable SPP website and 
on WAPA-RMR's OASIS website.

    Scheduling, System Control, and Dispatch Service (SSCD) is required 
to schedule the movement of power through, out of, within, or into one 
or both of the SPP Balancing Authority Areas (BAA) and certain parts of 
the transmission system not located within an SPP BAA. WAPA-RMR's 
annual revenue requirement (ARR) for SSCD will be separated between 
service provided for LAP transmission facilities in the LAP Zone (LAPZ 
or Zone 104) and for LAP transmission facilities determined to be in 
other SPP RTO transmission pricing zones. The ARR and ARR subtotals 
will be calculated using the formula outlined below.

Formula Rate

Define
A = Operation & Maintenance Expense for SSCD ($)
B = Administrative and General Expense for SSCD ($)
C = Depreciation Expense for SSCD ($)
D = Interest Expense for SSCD ($)
E = Prior Period True-up ($)
F = Applicable ratio share of plant for LAPZ and for other SPP RTO 
transmission pricing zones (%)
SSCD ARR = (A + B + C + D + E)
ARR Subtotals = (SSCD ARR) * F

    A recalculated ARR will go into effect every January 1 based on the 
above formula and updated financial data. WAPA-RMR will annually notify 
SPP and make data and information available to interested parties for
