Step-by-Step Instructions for Completing the Form No. 580

General Filing Requirements

Introduction
An automated form is required to be used for this collection of information. The form
provides respondents with drop-down menus and links, and allows storage of data for
easy retrieval and for updating in future filings.
Please direct any questions or comments about completing the 2018 FERC Form No.
580 (Form 580) to FERC-580@ferc.gov.
Who Must File
All jurisdictional utilities owning and/or operating at least one steam-electric generating
station of 50 MW or greater capacity, or having a majority ownership interest in a jointlyowned steam-electric generating station of at least 50 MW or greater capacity and that
had a cost-based rate tariff on file with the Commission during the reporting period, are
required to file a FERC Form No. 580. Utilities that did not have a cost-based rate tariff
on file during the reporting period with the Commission are not required to file the Form
580.
In the case where a FERC adjustment clause is in use in some capacity for an electric
generating station, either the operator, or the majority or minority owner must file the
Form 580 for 100% of the plant.
What to File
Respondents are required to file the electronic Form 580 with pertinent attachments
(e.g., rate and service agreements older than twenty years) and may on occasion need
to make revised filings.
De Minimis Circumstances
If a utility has a specific circumstance under which it thinks there is a compelling reason
not to answer a particular question or part of a question in the interrogatory, it can apply
for a waiver of that particular question or part thereof.
How to File
All documents must be filed via the Commission’s eFiling system. The eFiling
instructions are located on the Commission’s eFiling webpage:
http://www.ferc.gov/docs-filing/efiling.asp.
Detailed eFiling Instructions:
Start at the Commission’s home page: www.ferc.gov. Select on the Documents &
Filing tab and choose eFiling from the drop-down. If you have not previously
eRegistered, select the eRegister link and provide the requested information to
create an account. Otherwise, enter your registered email address and password.

Step-by-Step Instructions for Completing the Form No. 580

Select on “Log In.”
Select on “eFiling.”
Filing Type - Select on “Electric” in the first column. Select “Report / Form for
existing docket number” (Report / Form should show in the third column). Select
“Next.”
Select Docket - Enter the docket number (e.g., IN79-6-000) and select Search.
The docket number will show in a new table. Select the plus sign in the Select
column and a selected dockets row will drop down.
Select “Next.”
File Upload - Select the “Public” tab, then select “Browse” and select a public file to
upload. Enter a description in the space below the file name. Select “Upload.”
Continue doing this until all of your public files appear in the file upload table.
Select the “Privileged” tab, then select “Browse” to select your privileged file for
upload, enter a file description and select “Upload.” The eFiling system allows you
to attach up to 200 files.
There must be at least one Public file for each privileged submission. This can be
your cover letter describing the filing and asking for privileged treatment of your
question 5 submittal. It could also be your Form 580 public file.
Tip: Use PRIV as the first four characters of the file name for a privileged file to
avoid uploading a file with the wrong security level.
There is a feature at the bottom of the File Upload table to change the security
designation if the file was not uploaded as privileged and should have been.
When FERC accepts a filing with multiple security classes, the system puts the files
under different accession numbers and links them as document components in
eLibrary. Accordingly, eFile the privileged and public files during the same session
and they will be linked in eLibrary.
NOTE: If at any time you want to go back to a previous screen, press the “Back”
button provided on the eFiling screen, not the “Back” button in the browser.
Select “Next” at the bottom of the screen.
Specify Filing Parties – Select either “On behalf of another Party(ies)” and enter
the company name below or “As an Individual”, whichever applies. Select “Next.”

Step-by-Step Instructions for Completing the Form No. 580

Specify the person to whom communication should be addressed - Enter your
email address in the contact email block and select on “Add as Signer” or “Add as
Other Contact”. Note: a signer email address must be included, as every filing
must have a designated signer.
Submission Description – Enter: “Form 580 of [your utility name]”
Summary – Review the information shown. Ensure the file labeled as privileged
has the correct security level. If any of the information is incorrect, select the “Back”
button and correct your information as necessary. Select “Submit”.
A new screen will appear that states: “You have successfully submitted the filing
and will receive an email confirmation shortly”. Select the “Printable submission
confirmation receipt” button and a receipt will appear that states the date, time and
submission ID for your filing. You should also receive a confirmation of receipt by
email with the same information, a link to additional information for your filing and
the status of your filing. When the Commission accepts your filing, that status will
change to “Accepted”.
Go to: http://www.ferc.gov/help/filing-guide/file-ceii.asp for further information
regarding the filing of documents where privileged treatment is sought.
Requesting Privileged Treatment
The Commission is allowing privileged treatment of the answer to Question 5 if
requested pursuant to 18 CFR §388.112 and filed separately using the Form 580
Question 5 Privileged Addendum. You will need to file the privileged electronic
Question 5 Addendum with a cover letter requesting privileged treatment.
Go to http://www.ferc.gov/docs-filing/forms.asp#580 for Commission regulations
regarding the filing of documents where privileged treatment is sought.
Electronic File Naming Convention

andrate and service schedule designations that contain any type of wholesale automatic
adjustment clause (with the exception of those that are transmission-related) through
which any costs were passed during the reporting period.
Enter the docket number of the most current filing of the tariff/rate schedule/service
schedule containing the AAC. Identify whether it is a fuel adjustment clause or not.
Enter the tariff volume number containing the AAC and rate schedule number that was
most currently accepted by the Commission. Enter the first effective date of the tariff
volume/rate schedule containing the AAC. When selecting the drop-down arrow for
dates, a calendar will appear for use in entering dates. To zoom out while still in the
calendar, hold the left mouse button down for a couple of seconds, then release. This
will more quickly allow you to choose the date needed.

schedule already entered. Copy the similar row and then change the few items/s that
are different.
Enter dates of superseded or abandoned rate schedules and identify service schedules,
as requested, where AACs are located.
Question 2b:
One-time Filing of Documents Older Than Twenty Years
If any of the rate schedules and service agreements named in response to Question 2a
were first filed with the Commission before January 1, 1990, upload an electronic copy
of each with your Form 580 when you eFile. If the rate schedule or service agreement
was first filed before 1990 but since then has been refiled in its entirely, do not attach a
copy with your Form 580 filing. If the rate schedule or service agreement has been
refiled in its entirely since 1990, but certain sheets have been amended since then, do
not file the rate schedule or amended sheets with your Form 580 filing.
It is necessary for filers to provide this information electronically, in a text-searchable
format, in order that Commission staff may expediently analyze the filing in its entirety.
Once this information is submitted electronically, it will not be necessary to submit it in
future Form 580 filings. Enter the file name and a brief description of each in the spaces
provided. Select “Add Row” as many times as necessary to provide enough blank rows
in which to enter all of the required information.
If your utility has no fuel adjustment clauses (FACs), do not complete the remainder of
the Form. Questions 1 and 2 are the only questions you are required to complete. If
your utility has a FAC, you must complete the remainder of the Form.
Question 3:
Purchased Power
Report all purchased power contracts and agreements from a PURPA qualifying
facility (QF) 1, or an Independent Power Producer (IPP)2 in place during the reporting
period where costs were passed through an AAC. Provide the requested information by
reporting year. For each purchase, answer EITHER the questions in the column titled:
“only energy charges” OR the questions in the four columns titled: “the total cost of the
purchase of the economic power, whichever applies to the purchase”. If the Utility did
not purchase power and recover costs through an AAC, check the box provided and
continue with Question 4.

1

A QF is a generating facility which meets the requirements for QF status under the
Public Utility Regulatory Policies Act of 1978 and 18 CFR Part 292 of the Commission's
regulations, and which has either self-certified with the Commission or has obtained FERC
certification of QF status. There are two types of QFs: cogeneration facilities and small power
production facilities.

Question 4a:
Emission Allowances
If the Utility incurred emission allowance costs during the reporting year and recovered
any part of such costs through an AAC, enter the total amount recovered by year and by
origin (the “Origin of Emission Allowance Cost” is a dropdown field with the following
options: “self generation”, “purchased economic power”, or “purchased – other than
economic power”). Enter the docket numbers and dates of Commission acceptance of
these recoveries.
Question 4 asks for 2016 and 2017 costs that are recovered through an AAC. Your
Utility’s clause may not directly recover costs as they are incurred, i.e., the charges
assessed at various times in 2016 and 2017 were based on costs incurred during some
other time frame (preceding 2016). For this question, provide costs incurred in 2016
and 2017 whether or not they were reflected in 2016 and 2017 clause revenues.
Whether it is a charge or a credit, it is required to be reported.
If the Utility did not purchase power and recover costs through an AAC, check the box
provided and continue with Question 4b.
Question 4b:
Emission Allowance Recovery Through Other Than AACs
If emission allowance costs were recovered other costs than through an AAC, choose
“Yes” from the drop-down provided and explain how they were recovered: include rate
schedule and service agreement notations. Be specific.
If the Utility did not purchase power and recover costs through an AAC, check the box
provided and continue with Question 4b.
Question 5:

purchased? Which factors need to be taken into consideration when purchasing fuel.
Question 5e:
Fuel Contract – Fuel Quality Characteristics
What fuel characteristics had required characteristic limits named within the fuel
contracts active during the reporting period? Choose from the items shown. If the
characteristic is not shown, enter it in the column labeled “Other”.
Question 5f:
Affiliate Fuel Purchases
What percentage of the fuel purchased during the reporting period was purchased from
an entity that was in any way affiliated (see the glossary in the form for a definition of
“affiliated”) with the Utility? Check the appropriate boxes. Enter a fuel not listed in the
space for “Other” and provide the percentage purchased from affiliated entities for each.
Question 5g:
Fuel Contract Bidding Process
How are the potential fuel suppliers (bidders) qualified and ranked? Were fuel supplier
credit ratings checked, and if so, how?
If any aspect of the Utility’s fuel purchase policy practices differs for associated
companies, state the differences.
Is the lowest bidder automatically selected? If not, state the criteria used for fuel
contract selection and renegotiation.
Question 5h:
Fuel Procurement from Affiliates
Specify fuel procurement procedures used for affiliated and non-affiliated fuel sources
and suppliers.

11

Step-by-Step Instructions for Completing the Form No. 580

Question 6a & 6b: Fuel Supply Contract Specifications and Delivery
Characteristics
Note: Only enter fuel delivery information under contracts where costs were
subject to an automatic adjustment clause under 18 CFR 35.14. For example, if a
utility has an 18 CFR 35.14 clause for coal but not for oil, it should not report oil
contracts and deliveries in response to Question 6.
Questions 6a and 6b are connected electronically. This will ensure that all delivery
information is properly associated with the correct contract identification. Each delivery
row should be specific to a particular contract ID, reporting year and delivery plant.
Report contracts in any order, e.g., report all 2016 contracts followed by all 2017
contracts.
Step 1
Enter the information requested for the first reporting year of your first contract. If a
contract continues in effect month to month, i.e., there is no Contract Expiration Date
leave that field blank and enter “Y” in the “Is contract evergreen” field. If impurity
information does not exist, leave the space/s blank. Fuel quantities should be entered
in whole numbers, i.e., do not enter decimals.
Step 2
Enter the delivery information for that contract in response to Question 6b. Choose one
primary fuel origin and one purchase point type per delivery. If the fuel is delivered by
pipeline, choose “pipeline” as the primary origin (note: “Pool” has been added to the
dropdown). Choose a delivery plant for each delivery and enter the remaining
information requested. Enter fuel quantities in whole numbers, i.e., do not enter
decimals. If the fuel is delivered by pipeline and the quality specifications are “pipeline
quality”, leave the quality and impurity cells blank. If impurity information does not exist,
leave the space(s) blank. Enter Free On Board (FOB) plant cost. If FOB plant cost is
not available, enter FOB origin cost. You are not required to enter both costs. We prefer
that you do not include miscellaneous costs in your FOB plant costs. However, if
miscellaneous costs are not easily discernable from the fuel and freight costs include
them where applicable and state in a cover letter which miscellaneous costs are
included.
Step 3
Select on the “Add Delivery” button to add a blank row for entry of another plant’s
delivery under the contract just entered in response to Question 6a. Alternatively, select
the “Copy Delivery” button to add a row with delivery information identical to the one just
completed. Then select, Delete, and type information in any cell in that row to quickly
add a delivery that is similar to the one previously entered. Continue adding rows and
entering information until all deliveries are recorded.
Step 4

12

Step-by-Step Instructions for Completing the Form No. 580

Select the “Add Contract” button in response to Question 6a to add a blank row for entry
of a new contract. Select the “Copy Contract” button to copy the contract just entered
and to quickly add information similar to the contract just entered, e.g., for quick entry of
information for a subsequent reporting year of the same contract just entered.
Step 5
Repeat steps 2 through 4 until all deliveries under all contracts are recorded.
Question 6c:
Affiliate Fuel and Fuel Transportation Contracts
Provide the requested information concerning any affiliated entity that provides fuel
and/or fuel transportation services, whether or not the Utility used that entity during the
reporting period.
If the Utility has, for example, an agreement with an IPP that is not affiliated with the
Utility and the IPP is required to procure all of the fuel used to satisfy the daily calls for
power, do not report the IPP data in response to this question.
Question 7:
Contracted Fuel Quantity Shortfalls
Provide the requested information separately for each contract that experienced a
shortfall that is not under dispute, i.e., parties agree there was indeed a shortfall. If the
cause of the shortfall is not found in the Question 7a drop-down provided, choose
“Other” and type the cause in the drop-down space.
Question 8:
Contract Buy-downs and Buy-outs
Provide the requested information separately for each contract that was bought-out or
bought-down during the reporting years and that it is not under dispute. If the type of
change is not found in the Question 8a drop-down provided, choose “Other” and type
the cause in the drop-down space provided.
