Summary

The Western Area Power Administration (WAPA) has confirmed and approved provisional formula rates for Pacific Alternating Current Intertie (PACI) point-to-point transmission service in the Sierra Nevada region. These rates, effective April 1, 2026, supersede previous rates and maintain the existing formula-based methodology with updated effective dates.

What changed

The Western Area Power Administration (WAPA) has issued a notice confirming and approving provisional formula rates for the Sierra Nevada region's Pacific Alternating Current Intertie (PACI) point-to-point transmission service under Rate Order WAPA-211. These rates will be effective on an interim basis starting April 1, 2026, and will remain in effect through March 31, 2031, pending final approval by the Federal Energy Regulatory Commission (FERC). The notice states there are no material changes from existing formula rates, aside from updated effective dates, and that the existing formula-based methodology will continue.

Regulated entities utilizing PACI transmission services should note the new effective dates for these rates. While no immediate compliance actions are required as the changes are minor and primarily involve date updates, entities should be aware of the rate structure that will be in place until March 31, 2031. WAPA will submit the rate order to FERC for final confirmation and approval.

ACTION:

Notice of rate order concerning transmission service formula rates.

SUMMARY:

The formula rates for the Sierra Nevada (SN) region Pacific Alternating Current Intertie (PACI) point-to-point transmission
service have been confirmed, approved, and placed into effect on an interim basis (Provisional Formula Rates). These new formula
rates supersede rates for short-term sales on the PACI, PACI-T4 REV, PACI-T5 REV and PACI DLAP-T6 (approved under Delegation
Order No. S3-DEL-WAPA1-2023, Section 1.4.B). There are no changes from the existing formula rates for these services, and
there are no material changes aside from updating the effective dates.

DATES:

The Provisional Formula Rates under Rate Schedules PACI-C1, PACI-D1 and PACI-W1 are effective on the first day of the first
full billing period beginning on or after April 1, 2026, and 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and approval by the Federal Energy Regulatory Commission (FERC) on a final basis or until superseded.

Public Notice and Comment

WAPA-SN followed the Procedures for Public Participation in Power and Transmission Rate Adjustments and Extensions, 10 CFR
part 903, in developing these formula rates. WAPA-SN took the following steps to involve interested parties in the rate process:

  1. On April 23, 2025, a
    Federal Register
    notice (90 FR 17065) (Proposed FRN) announced the proposed formula rates and initiated a 90-day public consultation and comment
    period.

  2. On April 23, 2025, WAPA-SN notified Preference Customers and interested parties of the proposed rates and provided a copy
    of the published Proposed FRN.

  3. On June 18, 2025, WAPA-SN held a virtual public information forum. WAPA-SN's representatives explained the proposed formula
    rates, answered questions, and gave notice that more information was available in the Customer Rate Brochure.

  4. On June 18, 2025, WAPA-SN held a virtual public comment forum to provide an opportunity for Customers and other interested
    parties to comment for the record.

  5. WAPA-SN established a public website to post information about the rate process. The website is located at www.wapa.gov/about-wapa/regions/sn/sn-rates/Rate-Case-2025-WAPA-211.

  6. During the 90-day consultation and comment period, which ended on July 22, 2025, WAPA-SN received no oral comment submissions
    and no written comment letters.

PACI Point-to-Point Transmission Service Formula Rates

The provisional cost-based formula rate for PACI point-to-point transmission service will provide sufficient revenue to recover
annual operation, maintenance, replacement expenses, interest expense, and capital repayment requirements while ensuring repayment
of the project within the cost recovery criteria. The provisional equitable formula rates for PACI point-to-point transmission
service will aid and benefit the Central Valley Project (CVP) by offsetting project power costs.

PACI Point-to-Point Transmission Service Cost-Based Rate

The provisional cost-based rate for PACI point-to-point transmission service is used to move Federal power on the PACI transmission
line for Statutory Service.

WAPA-SN prepares a detailed cost-of-service study to determine the costs, by project, that supports the transfer capability
of each transmission system and the cost that supports the generation capability of the CVP system. Generally, the costs allocated
through the cost-of-service study for the transmission systems include operation and maintenance, interest, and depreciation
expenses. WAPA-SN's costs for scheduling, system control, and dispatch service associated with PACI point-to-point transmission
service are included and recovered through the transmission systems' revenue requirement.

PACI Point-to-Point Transmission Service Equitable Rate

The provisional equitable formula rate for surplus PACI point-to-point transmission service is used for non-Statutory Service
that is delivered and/or received between Malin to Round Mountain and/or Malin to Cottonwood Substation located within the
Balancing Authority of Northern California balancing authority area (BAA).

PACI Transmission Service Equitable Default Load Aggregation Point Rate

The provisional equitable formula rate for surplus PACI Default Load Aggregation Point (DLAP) point-to-point transmission
service is used for non-Statutory Service that is delivered from and/or received at Pacific Gas and Electric Company's DLAP
located within the California Independent System Operator BAA.

Comments

WAPA-SN received no separate oral and/or written comments during the public consultation and comment period.

Certification of Rates

I have certified that the Provisional Formula Rates for PACI point-to-point transmission service under Rate Schedules PACI-C1,
PACI-D1 and PACI-W1 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 WAPA-SN to develop the Provisional Formula Rates is available for inspection and copying at the Sierra
Nevada Regional Office, 114 Parkshore Drive, Folsom, CA. Many of these documents are also available on WAPA-SN's website at: www.wapa.gov/about-wapa/regions/sn/sn-rates/Rate-Case-2025-WAPA-211.
