Re: 
PJM Interconnection, L.L.C., Docket No. ER27-330-00_ 
 
Errata to Metadata Correcting Requested Effective Date and to Clarify that 
Requested Waiver Includes Tariff, Attachment DD, section 16.3 
 
Dear Secretary Reese: 
 
On October 29, 2026, PJM Interconnection, L.L.C. (“PJM”) submitted, pursuant 
to Federal Power Act section 205, 16 U.S.C. § 824d, revisions to the PJM Open Access 
Transmission Tariff (“Tariff”) to update the Reliability Backstop Procurement (“RBP”) 
rules to address, inter alia, issues identified in the Commission’s September 29 Order1 
(“October 29 Filing”).2  In the October 29 Filing, PJM requested that proposed new 
Tariff, Attachment DD, section 18.3A become effective January 29, 2027, and the 
remainder of the proposed Tariff revisions become effective February 28, 2027.3  PJM 
also sought a one-time, prospective waiver of certain requirements under Tariff, 
Attachment DD, section 16.4 
 
After submitting this filing, PJM discovered that when it entered the metadata for 
proposed new Tariff, Attachment DD, section 18.3A, PJM incorrectly entered an 
effective date of January 15, 2027, instead of January 29, 2027.  Accordingly, to correct 
this clerical error, PJM submits a corrected version of the sole affected tariff record, i.e., 
proposed new Tariff, Attachment DD, section 18.3A only to make the ministerial 
revision to the metadata, to be effective January 29, 2027, as proposed in the October 29 
 
1 PJM Interconnection, L.L.C., 196 FERC ¶ 61,245 (2026) (“September 29 Order”). 
2 PJM Interconnection, L.L.C., Proposed Amendments to the Reliability Backstop Procurement Motion for 
Extended, 32-Day Comment Period Request for Waiver of Tariff Attachment DD, Section 16.2 
Requirement to Investigate Capacity Shortfall, Docket No. ER27-330-000 (Oct. 29, 2026).

Filing transmittal letter.5  This correction to the metadata for proposed new Tariff, 
Attachment DD, section 18.3A does not otherwise change the original October 29 Filing, 
and the effective dates for all other tariff revisions submitted in the October 29 Filing are 
not affected by this filing. 
 
In addition, PJM discovered it inadvertently omitted in the October 29 Filing’s 
transmittal letter reference to Tariff, Attachment DD, section 16.3 in the caption, the 
heading to Part IV, and in the text on page 60.  Page 3 of the transmittal letter clearly 
states PJM’s request for waiver includes a requirement in Tariff, Attachment DD, 
section 16.3,6 but PJM inadvertently failed to carry through citations to this Tariff section 
in the caption and Part IV of the transmittal letter.  Accordingly, PJM has corrected the 
caption, the heading to Part IV, and page 60 of the attached transmittal letter to include 
references to Tariff, Attachment DD, section 16.3.  Indeed, page 60 of the corrected 
transmittal provides that “PJM seeks a one-time waiver of Tariff, Attachment DD, 
sections 16.2 and 16.3 upon completion of the 2029/2030 Base Residual Auction in the 
event such auction clears short.”7  PJM has attached hereto as Attachment A, a revised 
version of the transmittal letter, reflecting the corrections described above and making no 
other changes.8  
 
Please contact the undersigned with any questions. 
 
Respectfully, 
 
/s/ Ryan J. Collins

5 Since the record and clean and marked versions of proposed Tariff, Attachment DD, section 18.3A, as 
Attachments A and B are correct, for purposes of this ministerial supplemental filing, a clean and marked 
version of Tariff, Attachment DD, section 18.3A are not being filed herewith.  
6 See October 29 Filing, Transmittal Letter at 3 (“PJM conditionally requests waiver of the requirement in 
Tariff, Attachment DD, section 16.3 that PJM ‘declare a capacity shortage and make a filing with FERC for 
approval to conduct a Reliability Backstop Auction’ following three consecutive Delivery Years in which 
the Base Residual Auction clears short.”). 
7 Id. at 60. 
8 For ease of review of the corrections, a redline of the corrections to the October 29 Filing transmittal letter 
are attached hereto as Attachment B.
