REPORT INSTRUCTIONS
GENERAL INSTRUCTIONS
Revisions to Data Previously Reported through the efile System
Submit revisions to data previously reported as soon as possible after the error or omission is
discovered. Do not wait to revise data until the next reporting month’s form is due. Revisions or
adjustments to data should be made only to the survey month(s) to which they pertain (i.e., do not adjust
the current month to reflect a revision or adjustment to a prior month submission).
Log on to the efile system, re-key revised data, indicate in Schedule 9 the nature and date of
the revision, and resubmit the data. If the efile form is locked,
contact EIA
to request the
form be opened for revision.
Remember to save and RESUBMIT (click on the SUBMIT button). Resubmitting will allow
the validation edits to re-validate the revised data element(s).
Send an email message to
EIA-923@eia.gov
indicating the following:
(1) the reporting month and year for which data are being revised,
(2) the data that has been revised, and
(3) the date of the revision.
Alternatively, if the efile system has been closed for the reporting period, please send an email message
containing your changes to EIA-923@eia.gov, and indicate ‘Revision’ in subject line. Be sure to include
your Plant ID, the specific revision, and the month and year that is being revised.
Revisions to Data Previously Reported by Facsimile or Email Message
If you report via facsimile or email, you may send a corrected copy of the form, but be sure to indicate
the four items, discussed above, in Schedule 9.
Correcting Prepopulated Information
For efile users, much of the information on the form is prepopulated by EIA. Verify the administrative
information on Schedule 1, and if changes are needed, send revisions via email to EIA-923@eia.gov.
Validation Edits
For efile users, data that fail the interactive validation edits will be amassed into an edit log. Upon hitting
the “Submit” button, the system will notify you if there are edits in the log. You will be directed to the log
and given the opportunity to either revise the data in question or override the edit flag (thus leaving the
response values that triggered the error as is). When an edit is overridden, the system will ask for a
comment/explanation. Please leave a comment that explains the anomaly, rather than simply stating the
data are correct. Each comment is reviewed by EIA and, if the comment does not sufficiently explain the
anomaly, EIA will contact you for clarification.

REPORT INSTRUCTIONS
SCHEDULE 1. IDENTIFICATION
Verify preprinted information. Provide revisions to EIA via email at EIA-923@eia.gov.
1. Plant Name, Plant ID, and State: These data are established on the Form EIA-860. Revisions should
be coordinated with the
Form EIA-860
staff.
2. Survey Contact: Enter the person primarily responsible for completing the form.
3. Supervisor of Contact Person for Survey: Enter the supervisor of the primary contact as an alternative
person in the event the primary contact becomes unavailable. The Survey Contact and Supervisor
cannot be the same person.
4. Report for (Company and Plant): Enter the name of the operating company and plant. The plant
identification number is assigned by EIA. Enter the plant state and county, and month or year for which
data are being reported. State codes are two-character U.S. Postal Service abbreviations.
5. Regulatory Status: Indicate if the plant should be considered either a utility-operated regulated plant
(plants where costs are recovered through rate regulation) or unregulated plant (independent power
producers and commercial and industrial sector plants).
6. CHP Checkbox: Indicate whether or not this facility is a combined heat and power plant (CHP). A CHP
plant produces both electric power and another form of useful thermal output, such as heat and/or steam
for industrial processes, district heating/cooling, steam for purchase or hot water) from a common
source.
7. CHP Plant Efficiency: If the CHP checkbox is “YES”, enter the efficiency of the combined heat and
power plant. Report the annual average total CHP plant efficiency.
To calculate the total plant efficiency, apply the following formula by dividing the sum of the energy
outputs in Btu, including gross generation and useful thermal output, by the sum of the energy inputs
(total fuels consumed converted to Btu).
If gross generation is not available, use net generation as an approximation. Total Fuel Consumption
(MMBtu) is found using Schedule 3 fuel quantities multiplied by their average heat content.
SCHEDULE 2. COST AND QUALITY OF FUEL PURCHASES
General Instructions
Required Respondents:
1. Plants with one or more generating units primarily fueled by coal, natural gas, petroleum coke,
distillate fuel oil, or residual fuel oil. Primary Fuel for each generator is reported on the Form
EIA-860.
2. Plants where the total generator nameplate capacity with a Primary Fuel of coal is 50 megawatts
or greater; or the total generator nameplate capacity with a Primary Fuel of any combination of
natural gas, petroleum coke, distillate fuel oil, or residual fuel oil is 200 megawatts or greater.
3. Fuel transfer terminals and storage facilities serving generating plants, if the fuel purchases
cannot be reported at the plant level.

REPORT INSTRUCTIONS
Fuel transfer terminals and storage facilities guidelines: Report fuel purchases where quantity, cost,
and quality data CANNOT be reported by the individual plants served by the fuel terminal. Report
purchases either on the fuel terminal report OR the plant report, not both. Fuel terminals must list the
plants served on Schedule 4B. Report transfers out as negative adjustments to stocks on Schedule 4A.
Report for each fuel purchase: Report for purchases of all coal types, petroleum coke, distillate and
residual fuel oils and natural gas by type of fuel, supplier, purchase type, contract expiration date,
average cost per MMBtu, fuel quality, and for coal mine origin. Do not aggregate purchases. Report
contract and spot market purchases separately, unless specifically instructed below.
Annual Respondents may aggregate some purchases for the entire year provided the contract type and
other identifying information, such as mine origin, are identical. For aggregated data, report weighted
average costs and quality data.
Coal Purchases: Report data by supplier and mine source. The mine information is reported on
Schedule 2, Part C.
Coal or petroleum coke which will be converted to synthesis gas at an Integrated Gasification
Combined-Cycle (IGCC) plant: Report the fuel as it is received (i.e., as coal or petroleum coke).
Petroleum Product Purchases: Report data by fuel type, supplier or broker, or refinery and, if
applicable, port of entry. Report purchases of residual fuel oil, distillate fuel oil, and petroleum coke.
Do Not Report the Following: Waste oil, kerosene, jet fuel, propane, or other petroleum products.
Natural Gas Purchases: Report natural gas purchases by supplier. Report each contract purchase
(not spot purchases) as separate line items -- never aggregate the contracted purchases. Spot market
natural gas purchases from various suppliers may be aggregated where it is impractical to list each
individually such as when numerous suppliers are used for many relatively small transactions.
However, it is preferable to list each supplier separately. If you aggregate your data, report the
weighted average cost and quality.
Do Not Report the Following: Other gases such as manufactured gas (coke oven, refinery, or blast
furnace gas), propane, landfill gas, or other miscellaneous gaseous fuels, or natural gas injected into
storage. Report stored gas when it is received at the plant as an Adjustment on Schedule 4A. Do not
report costs associated with storage.
SCHEDULE 2. PART A. CONTRACT INFORMATION, PURCHASES, AND COSTS
1. Fuel Supplier Name: Supplier names and fuel codes are preprinted from the previous month’s report.
Delete unneeded rows. Add supplier/fuel types from the drop-down lists. If the supplier is not on the list,
contact EIA
to have a new supplier added. If you choose “Name Pending” while waiting for a new
supplier to be added, you MUST report the full supplier name in an override comment in response to the
edit flag before the data can be submitted.
2. Purchase Type or Tolling Agreement: Use the following codes:
C – Contract Purchase – Fuel received under a purchase order or contract with a term of one
year or longer. Contracts with a shorter term are considered spot purchases (See below.)
NC – New Contract or Renegotiated Contract Purchase – Fuel received under a purchase
order or contract with a duration of one year or longer, under which deliveries were first made
during the reporting month
S – Spot-Market Purchase – Fuel received under a purchase order or contract with a duration
of less than one year

REPORT INSTRUCTIONS
T – Tolling Agreement – Fuel received under a tolling agreement (bartering arrangement of fuel
for generation)
3. Contract Expiration Date (MMYY): Report for Purchase Types C and NC the month and the year the
purchase order or contract expires. For example, report “1119” for a November “2019” expiration date.
This column should be left blank for Purchase Types S and T.
4. Energy Source: Identify fuels using the energy source codes listed in Table 1 for coal, petroleum coke,
natural gas, distillate fuel oil, and residual fuel oil. A complete detailed list of energy sources is included
in
Table
8.
5. Units of Measure:
Coal and petroleum coke receipts: short tons on an as-received dry basis (if wet, indicate in a comment
on Schedule 9)
Petroleum products’ receipts: barrels
Natural gas: thousands of cubic feet (Mcf)
6. Quantity Purchased: Report the quantity of the fuel purchases for fuel that will ultimately be used for
the generation of electricity and, at combined heat and power plants, for useful thermal output (process
steam, district heating/cooling, space heating, or steam delivered to other end users).
As far as possible, do not include fuel that will be used in boilers with no connection to an electric power
generator or for use in other equipment. If fuel purchases cannot be separated, provide a comment on
Schedule 9, Comments.
Report start-up and flame-stabilization fuels.
When fuel is purchased by and received at the plant and a portion is resold, report the quantity minus the
amount resold, but report the original average costs and quality of the purchase.
7. Total Delivered Cost (for coal, petroleum products, petroleum coke, and natural gas): Enter the
delivered cost of the fuel in cents per million Btu (MMBtu) to the nearest 0.1 cent. Include all costs
incurred in the purchase and delivery of the fuel to the plant. Do not include adjustments associated with
prior months’ fuel costs.
Include any penalties/premiums paid or expected to be paid on the fuel delivered during the month in the
delivered price for fuel shipped under contract. Make subsequent adjustments only by revising the cost
in the month it was reported. Report only the current month fuel costs associated with the current month
fuel deliveries. If a portion of a fuel purchase is resold, report the average cents per MMBtu paid for the
original purchase. Do not discount the costs by the revenue received for the sale of the fuel.
For coal, include maintenance and depreciation costs of coal delivered in railcars owned by the plant. Do
not include unloading costs.
For natural gas, include the following pipeline charges: fuel losses, transportation reservation charges,
balancing costs, and distribution system costs outside of the plant. Because these types of fees can
skew the cost of the fuel per MMBtu, provide an explanation in an edit log override comment when the
price falls outside the range of expected cost, (e.g., “This price includes a reservation fee of x dollars.”).
