Advice Letter Submission Information

Revised Advice Letter Process Effective March 2020

Effective March 2020, the Energy Division Tariff Unit (EDTU) introduced a new streamlined Advice Letter process that is more efficient and environmentally friendly.  The major changes are the following:

  1. Entities shall file Advice Letters (and all related documents) electronically via e-mail only to  We no longer accept hard copy Advice Letter submissions.
  2. For PG&E, SCE, SoCalGas and SDG&E, upload the document to our CPUC Advice Letter database.

Requirements for a NEW Advice Letter

  1. Advice Letter - Rules for filing Advice Letters are available in General Order (G.O.) 96-B. For references, view previous advice letters by searching the CPUC Advice Letter database. Advice Letters must be in searchable PDF format.
  2. Advice Letter Summary Form - Complete the AL summary form. Failure to submit a complete AL Summary Form may result in the Energy Division Tariff Unit (EDTU) rejecting the Advice Letter (AL) filing.
    • An entity’s AL filing must be numbered sequentially, beginning with number 1 for the first AL filed. The entity may send an email to ‘’ to verify or request information about the next available number to be used in the AL filing.
    • The CPUC Utility Reference Number (will be assigned to you by CPUC Energy Division Tariff Unit, if you are a new utility to the Advice Letter).
    • Specify the Advice Letter Tier - refer to G.O. 96-B if you need help determining the tier.
    • The required fields on this form are: Company name/CPUC Utility No., Utility Type, Contact Person, Advice Letter (AL) #, Tier Designation, Keywords(please see accompany sheet for Keyword designation), Requested Effective Date and Number of tariff sheets. Other fields are required if it is applicable to your Advice Letter.
  3. Service List - All AL filings (including supplements) must be served on the appropriate service list.

Requirements for an EXISTING Advice Letter

  1. Send documents associated with the existing Advice Letter electronically via email to and reference the existing Advice Letter Number. Relevant documents can include supplements, substitute sheets, protests, replies to protests, comments, comments on resolutions, workpapers and all Advice Letter related documents sent to the service list.
    • If filing a supplement, use the same AL number of the original filing and affix the letter "A", "B", "C" and so on after the number.  For example, if the AL is sequentially an AL 5-E, it will be AL 5-E-A (for the first supplement) or AL 5-E-B [for the second supplement, and so on).
  2. For PG&E, SCE, SoCalGas and SDG&E, upload the documents to our CPUC Advice Letter database, and be sure to reference the CPUC Utility Reference Number.

Frequently Asked Questions

1. How do I check the status of an Advice Letter?

2. How do I send confidential Advice Letters and related documents?

3. When submitting supplements, do I need to indicate if the supplement is replacing the original or the previously submitted supplement and original, or is supplementing the original and previously submitted supplement?

  • Yes! When submitting a supplement, please indicate whether it is replacing or supplementing. In other words, please be as clear as you can when submitting your supplement by telling us exactly what it is supplementing and/or replacing. 

Please remember that the supplement (and all Advice Letter material) needs to be submitted to the same service list(s) as the original Advice Letter.
