FERC issued a notice on June 11th authorizing changes to the eTariff requirements. These changes included adding a new “Lead Applicant” field and allowing Word and Excel file types to be uploaded in tariff records.
The changes were expected to go into effect on September 30th, however on September 9th, FERC issued a notice of extension to November 25th.
Along with the extension, FERC decided to include new filing codes and added a new filing category. To ensure you’re ready for the transition, here is an explanation of the new filing codes and how and when they should be used.
Compliance Filing Changes
One major change to eTariff Filing codes is the separation of compliance filings into two categories: “Compliance” and “Compliance_New”.
The filings that fall under the “Compliance” category are used when a sub-docket is needed (pretty much the same setup as compliance today). “Compliance” filings will require an associated filing. More specifically, codes 80, 70, 580, 790, and 40 are now "Compliance Filing – subdocket". These codes need an associated filing ID, or they will not pass FERC validation.
“Compliance_New” category is a compliance filing that will not have an associated filing/sub-docket. These filings will receive a New Docket. More specifically, codes 85, 75, 585, 795, and 45 are the new "Compliance Filing – new docket" codes. These should not have an associated filing, and if you try to add one, they will fail validation.
New Filing Codes:
Along with compliance filing changes, FERC is also updating/adding some baseline codes.
Baseline code that distinguishes between Initial Rate Baseline and Rate Change Baseline
Filing code 390 (TCS companies) is being renamed to “New Tariff Database (Rate
Change Baseline).”This code is to be used for baseline filings to change existing rates
under FPA 205(d) 35.13(a)(2)(iii).
New Filing Code 395 (TCS Companies) is titled “New Tariff Database (Initial
Rate Baseline),” which will be used for an initial rate baseline (as 390 used to be).
Filing code 400 (for MBR companies) is being renamed to “New Tariff Database (Rate
Change Baseline).” This code is to be used for baseline filings to change existing rates.
New Filing Code 405 (for MBR Companies), titled “New Tariff Database (Initial
Rate Baseline),” is used for initial baseline filings establishing a rate.
FERC wants to provide utilities with options to reflect their intentions when filing their baseline. It seems that “initial” baseline filings will use codes 395 or 405.

New Requirements bring new Validations:
The following validations FERC Codes have been added to FERC rules:
183 | Lead Applicant Company Identifier not found – received when the company ID set for the lead applicant is not valid or in FERCs system |
184 | Lead Applicant Company Identifier has not been approved yet – Received when the company ID was been created, but it is pending with FERC still |
185 | Applicant Company Identifier must be text – (ex: C012345). |
186 | Lead Applicant Company Identifier required – received when the field was left blank. The field is required, so if there’s no lead applicant, then enter submitting company CID. |
187 | This type of filing code establishes a new docket; the filing should not include an associated filing identifier. – received when an associated filing ID was set for a compliance_new filing. To fix: remove the associated filing ID. |
188 | Attachment files have a duplicated file name. – received when the file name is the same for two attachments in the filing. |
189 | Lead Applicant Company Identifier must start with the letter C (see code 185 for example). |
Action Items and Reminders
Review FERC Regulations: While this guidance aims to educate, it does not constitute legal advice. Utilities must familiarize themselves with the updated Federal Regulations to ensure appropriate code selection.
Familiarize Yourself with Code Changes: Study the new filing codes, renamed codes, and their corresponding program codes. Ensure you understand which codes necessitate associated filings and which initiate new dockets.
Prepare for New Validations: FERC has implemented additional validations. Anticipate potential errors related to lead applicant identification, file naming, and associated filings for "Compliance_New" codes.
System Updates: Systrends will update servers on November 24. Allocate time prior to November 25 to acclimate to the new filings and validations within the Systrends platform.
