Notice of Proposed UGP Transmission/Ancillary Formula Rates
(Rate Order No. WAPA-218) for SPP RTO Expansion into Western
Interconnection - Federal Register notice on December 30, 2024
(89 FR 106476), Announcement of Consultation and Comment Period
As described in the December 30, 2024, Federal Register notice (FRN-Proposed-UGP-Trans-Anc-Service-Rates-2024-1230.pdf),
the
Upper Great Plains (UGP) region of the Western Area Power
Administration (WAPA) proposes new formula rates for the
Pick-Sloan Missouri Basin Program--Eastern Division (P-SMBP--ED)
transmission and ancillary services for UGP’s costs to be
recovered under the Southwest Power Pool’s (SPP) Open Access
Transmission Tariff (Tariff) should UGP decide to expand its
participation in SPP in the Western Interconnection. These
rates will be used by UGP to provide rate data to SPP, the
Regional Transmission Organization (RTO) of which UGP is a member,
after SPP’s planned expansion of the RTO into the Western
Interconnection on April 1, 2026. The existing UGP rates for
services expire on September 30, 2025, but are being extended
under a separate rate process, Rate Order No. WAPA-217, to
continue to provide existing rate data to SPP between October 1,
2025, and final implementation date of the planned RTO expansion
into the Western Interconnection. The proposed rates
will address UGP operating changes and new provisions and
settlement requirements under the proposed revisions to SPP’s
Tariff filed with the Federal Energy Regulatory Commission
(FERC) to accommodate their RTO expansion into the Western
Interconnection. The proposed formula rates will
become effective on the go-live date of the expansion of the SPP
RTO into the Western Interconnection (scheduled for April 1, 2026,
as of the date of this notice) and will remain in effect for five
years from the effective date, which with an effective date of
April 1, 2026, will be March 31, 2031, or until superseded.
The proposed rates continue the formula-based methodology that
includes an annual update on January 1 of every year, to the
financial data in the rate formulas, and include Rate Formula
Implementation Protocols to clarify UGP’s rate implementation and
annual update procedures with changes related to the planned RTO
expansion in the Western Interconnection to: (1) Terminate the
Balancing Authority Area (BAA)-related ancillary services (and
associated worksheets in the Rate Formula Templates) for
Regulation and Frequency Response Service, Operating
Reserves—Spinning Reserve Service and Supplemental Reserve
Service, Energy Imbalance Service (EI), and Generator Imbalance
Service (GI); (2) Incorporate changes in the Rate Formula
Templates to calculate the Annual Transmission Revenue Requirement
(ATRR) for the Miles City Direct Current (DC)Tie for SPP’s
settlements purposes related to SPP’s proposed DC Tie Access
Charge; (3) Incorporate changes in the Rate Formula Templates to
calculate the subtotals of the ATRR for the SPP West and East BAAs
separately for SPP’s settlements purposes; (4) Incorporate a new
worksheet in the Rate Formula Templates to calculate the
Incremental Market Efficiency Use (Incremental MEU) share for the
Miles City DC Tie; (5) Incorporate changes in the Rate Formula
Templates to calculate the ATRRs for SPP Base Plan Upgrades
separately for SPP’s settlements purposes in each of the SPP West
and East BAAs; and (6) Update, as needed, the existing Rate
Formula Templates to smooth the true-up process impacts, increase
transparency, and incorporate the changes noted above.
The
formal consultation and comment period began with
the publication of the Proposed FRN on December 30,
2024, and ends 90 days later, on March 31, 2025.
UGP will present a detailed explanation of the
proposed formula rates and other modifications at a
public information forum. Public information and
comment forums have been scheduled as follows:
