    Company Registration Top
    Company Registration

    eTariff requires that every required filer have a Company Identifier as part of an eTariff filing. A Company Identifier is obtained from the Commission. Information on acceptable company name formats and suggestions on how to populate the Company Registration on-line form are available from the Instructions for Company Registration.PDF

    You will need one person eRegistered to do business with the Commission to register a company. Once you have assembled the necessary information, proceed as follows:

    1. If you are not eRegistered, go to and click on New User. If you are eRegistered, skip to step (c).

    2. Fill out and submit the form. You will receive and ID and password.

    3. Go to Use your ID and password to log in to FERC Online.

    4. Go to the company registration page at, and click on “Register a company for the first time”

    5. Under Regulatory Program, select “NGPA 311 and NGA Hinshaw Gas Pipelines”, fill out the remainder of the form and submit.

    6. You will receive a Company Identifier (CID) in a couple of business days.

    7. Note that once you have registered your company, you will use the Company Identifier and password for all subsequent eTariff filings. You should not re-register your company again. If you do not know if your company has already been registered, you can search the Commission posted list of registered companies.

    8. Once you have obtained a Company Identifier and password, proceed to Making an eTariff Filing.

    Making an eTariff Filing

    If you are using:

    • Third party vendor software,
    • Your own software, or
    • A service,

    Follow their instructions. It is always advisable, even when using eTariff software or services, to test your filing against the Commission’s Sandbox described in Step 2 below. The Commission cannot recommend and does not review or endorse any eTariff software package or vendor. The North American Energy Standards Board also does not recommend or endorse any eTariff software. However, they do maintain a list of eTariff vendors External on their home page.

    If you are not using eTariff software, simple eTariff filings can be created using the following instructions.

    1. Create your .xml file
      1. Download a sample.xml file.
      2. You can use a text editor, such as Notepad, to edit an .xml file. Standard word processors and other similar software may not work well.
      3. Use the eTariff codes for Part 284 rate filing document and XML Schema Tables PDF to populate your .xml file with the correct metadata.
      4. You need to obtain a binary 64 converter for the binary fields. Binary 64 converters can be found online. These converters will convert word processing, spread sheets and many other electronic documents, including formatting codes, into binary text fields, so your tariff and documents can be displayed properly. Be aware that this will look like meaningless text. When encoding your attachments and tariff records, set the encoder to UTF-8 character set.
      5. You can use the copy command to copy text from your source tariff file (.rtf or .pdf) and paste into the ‹record_plain_text› field.
      6. Your proposed effective date should not be before the date of filing.
      7. If your tariff filing requires a filing fee, please follow the special instructions on how to make this payment and how the use the resulting documentation in your .xml filing.
      8. Save your .xml file.
      9. Zip your .xml file (and only your .xml file – not the documents).

    2. Submit your xml
      1. Submit your xml file to our Sandbox Electronic Test Site
      2. Please review the Test File Instruction Guide PDF
      3. Correct any pertinent errors you receive and resubmit to the Sandbox.
      4. Continue correcting any errors and resubmitting until no pertinent errors are reported.

    3. Submit your Filing
      1. Log on to FERC Online.
      2. Click eFiling
      3. Under “How is your filing to be directed?” choose Gas
      4. Under “What kind of filing are you making?” choose eTariff
      5. Under “Filing Type (Fee)” choose “eTariff” (even if your tariff filing requires a fee – see the special instructions) and click Next
      6. Select your CID. The CID that you use here should be the same one used in your .xml filing.
      7. Upload the zip file that contains your .xml file
      8. You will receive 2 emails verifying that we received your filing:
        1. If you receive any errors, amend your .xml file and resubmit your filing.
        2. If you receive Warnings, your filing has been received, but you need to double-check that you submitted the correct information as such warnings are indications that what you submitted is different than what we normally receive.
    Market Based Rate Filings Top
    Market Based Rate Filings

    In order to authorize the applicant to charge market-based rates, the Commission must find that the applicant lacks significant market power, i.e., that the market is sufficiently competitive to preclude the pipeline from profitably maintaining prices above competitive levels for a prolonged period of time.

    Market-based application must include:

    1. Describe proposed service.
    2. Define relevant product and geographic markets.
    3. Provide applicant's ownership and then list affiliated energy companies, services provided, and their location. If an affiliate operates in the same geographic market, the market shares of the applicant and the affiliate should be combined.
    4. Identify good alternatives to the proposed service - which parties provide similar service within the same geographic market. List the applicant's competitors and location.
    5. Include market share and Herfindahl-Hirschman Index (HHI).1 calculations to measure market concentration.[1] The Commission’s traditional HHI threshold is 1,800.
    6. Discuss other relevant competitive factors such as ease of entry and excess capacity held by competitors.
    7. Describe how the applicant's rates compare to the competitors.


    1 [1] The HHI Index is used as the initial screen to determine market concentration. It is an indicator of the likelihood that the applicant alone or together with other suppliers can jointly exercise market power in a given market. As such, the HHI Index can suggest but not prove whether a market is competitive or not. It is not a definitive statement whether the applicant can exercise market power.
    Notices of Cancellation or Succession to a Tariff Top
    Notices of Cancellation or Succession to a Tariff

    The pipeline must notify the Commission if the pipeline desires to cancel a service or its complete tariff (18 C.F.R. § 284.123(e) External, a change in operations). This notice is required to be submitted through the eTariff system. If the tariff is the only tariff the seller has on file, or all of the records under one tariff are being cancelled, then the seller must also as part of that filing request that the Commission cancel that Tariff ID using a complete tariff Cancellation type of filing. However, if cancelling just part of the tariff, the pipeline should file a revision to the tariff that either removes the service from the tariff text or cancels the tariff records that contain the service.

    A seller must notify the Commission if the pipeline merges with another entity, or has its tariff adopted by another entity (18 C.F.R. § 284.123(e) External, a change in operations). The notice is required to be submitted through the eTariff system as a Tariff Revision.
    Name Change Top
    Name Change

    If the pipeline changes its name, it must notify the Commission. With the adoption of eTariff, there are two steps to the process:

    1. Company Registration. Log in using the Company Identifier and password, and modify the pipeline’s name and effective date. Company Registration only accepts proposed effective dates the later of the date of the logging in or the proposed effective date.

    2. Tariff Revision. If the company’s name appears in the text of the tariff, then the company must file a tariff revision through eTariff to modify the name. If the pipeline’s name is not in the tariff text, then the modified Company Registration will be reflected as part of the Public Tariff Viewer’s meta data and no tariff filing is required.
