Answers to Anticipated Questions for New Form EIA-923, “Power Plant Operations Report”

I am currently registered for the survey Form EIA-906 and/or survey Form EIA-920. Will I need to re-register prior to submitting my data for Form EIA-923?
No, you will automatically have access to the new Form EIA-923 once the form is open for data collection.

What is Form EIA-923 and why has EIA come up with another form for me to fill out?
Form EIA-923 replaces Forms EIA-906, EIA-920, EIA-423, and FERC Form 423, and will collect some data elements that were formerly submitted on Form EIA-767.  EIA has determined that it is more efficient to collect the data elements from the various predecessor forms on a single form going forward.

   Summary of new and deleted data items

Who is required to report on Form EIA-923?
Form EIA-923 is a mandatory report for all electric power plants and combined heat and power (CHP) plants that meet the following criteria: 1) have a total generating capacity of 1 megawatt (MW) or more and 2) are connected to the electric grid.  To lessen the reporting burden, information from a sample of plants is collected on a monthly basis.  Plants that are not selected to respond monthly must respond annually for the calendar year.

When is Form EIA-923 due?  
Monthly respondents are required to file Schedule 1 through Schedule 5 and Schedule 9 of this form with EIA by the last day of the month following the reporting period.  For example, if reporting for July, survey data are due on August 31.  Schedule 6 through Schedule 8 must be filed by March 30 following the end of the reporting year.
Annual respondents are required to file the form with EIA by March 30 following the end of the reporting year. 

How should I submit Form EIA-923?
You should submit your data electronically using EIA’s secure Internet Data Collection (IDC) system.   This system uses security protocols to protect information against unauthorized access during transmission.

If some of my colleagues and I are splitting the duties of completing Form EIA-923, will we all need to use the same id and password for on-line filing?  
That depends. Respondents who have reported on Form EIA-906 (or Form EIA-920) in the past will have valid credentials for Form EIA-923 for those plants for which they have reported. If the respondent decides to keep multiple plants under one set of credentials, EIA will honor that request. If the respondent requests additional credentials, EIA will issue one set of credentials for each unique plant id code. However, no more than one set of credentials will be issued for a unique plant id code. It is up to the respondent to decide who will have access to those credentials to facilitate completion of the Form EIA-923.

What about my annual 2007 data? Should I report it on the Form EIA-906 to be consistent with my 2007 monthly submissions? 
No.  Annual 2007 data should be submitted on Form EIA-923.  Form EIA-906 is not valid for annual 2007 data submissions.

 What about my fuel stocks?  These numbers were kept confidential on Form EIA-906.  Will these numbers remain confidential? 
Yes.  EIA will continue to keep these data elements confidential

What about the respondent id number that I use on Form EIA-906?  I don’t see it here.
Form EIA-923 data collection is based on the facility or plant id number.

The linkage between my boilers and my generators is not always one-to-one.  How should I handle these situations? 
The data for a plant’s boilers is reported on Schedule 3A, while data for its generators is reported on Schedule 5A.  Form EIA-923 does not ask for the configuration of the boilers to generators.

I only filled out the Form EIA-906 in the past.  Some of this new information seems to be coming from other predecessor forms.  I’m not sure who filled them out or if they even were filled out.  Am I responsible?  Are you able to help me determine who completed these forms earlier? 
If different individuals filled out different forms in the past for your organization, perhaps you will continue to have multiple individuals work on Form EIA-923.  It is up to you, the respondent.  We will provide you with the names of those who have submitted the predecessor forms.  Please do not hesitate to contact EIA with any questions or concerns that you have.

If I report on a monthly basis for some of my plants and annually for some, will I use the same id and password for each? 

When should I call the survey manager and when should I call the IDC Help Desk? 
If you have questions about the data requested on Form EIA-923, you should contact the survey manager. See all EIA-923 contacts
If you experience a technical problem logging into the Internet Data Collection system, or if you have a problem using the system, call 202-586-9595 or email us at CNEAFHelpCenter@eia.doe.gov.

Should I call the survey manager with questions about all schedules or are some of them delegated to other EIA staff?

What is the difference between gross generation and net generation?
Gross generation is the total amount of electric energy produced by generating units and measured at the generating terminal in kilowatthours (kWh) or megawatthours (MWh). Net generation is the amount of gross generation less the electrical energy consumed at the generating station(s) for station service or auxiliaries. Note: Electricity required for pumping at pumped-storage plants is regarded as electricity for station service and is deducted from gross generation.

We only meter net generation.  What should I do?
Submit your net generation and leave the gross generation space blank.  Please make any additional comments in Schedule 9.

Why am I not reporting Total Electricity Generated (MWh) that used to be on EIA-920 Schedule 2?
You now will report both Gross and Net generation by Generator ID on EIA-923 Schedule5A or 5B

How do I know if I have to complete Schedule 3A or 3B?
Schedule 3A will be completed by plants with a total steam turbine capacity of 10
megawatts and above that burn organic fuels. Report only fuels consumed in the boilers,
or for HRSGs in duct burners. Report consumption in combustion turbines or IC engines
on SCHEDULE 3. PART B. Schedule 3B will be completed by plants with organic-fueled steam turbine capacities under 10 MW, combustion turbines, IC engines, and pumped storage hydroelectric units.

How do I know if I have to complete Schedule 5A or 5B?
Schedule 5A will be completed ONLY for generators at steam-electric organic-fueled plants with a total steam turbine capacity of 10 megawatts and above. Report generation for all other types of prime movers (combustion turbines, IC engines, wind, or hydroelectric turbines), and steam turbine plants with less than 10 megawatts total capacity or fueled by nuclear, solar, geothermal, or other energy sources on SCHEDULE 5. PART B.

I can only report Gross Generation on Schedule 5A or 5B.  Is this a problem?
Industrial or Commercial Combined Heat and Power Plants (CHP) may report ONLY gross generation if net generation is not measured.  Otherwise, you must also report net generation.

Where do I report my ending fuel stocks balance on the new EIA-923?
Use EIA-923 Schedule 4, column 4 to report this month’s ending fuel stocks.


Questions on old Form EIA-423 and FERC Form 423 filings

What is Schedule 2?
Schedule 2 replaces the former Form EIA-423 and FERC Form 423.

Who must file Schedule 2?
All regulated and nonregulated generating plants with a fossil-fueled nameplate capacity of 50 megawatts or greater, including regulated plants that previously received waivers from FERC, including all generator types (e.g. combustion turbine, combined cycle, gas turbine, internal combustion units, etc.)

How often will I have to submit Schedule 2?
EIA will let you know if you will be among those reporting monthly or those reporting annually.

Are there any data differences between the new Schedule 2 and the old Form EIA-423?
Yes, there are new data elements….

  • Commodity cost of fuel for coal and natural gas,
  • Mercury content for coal,
  • Fuel transportation modes,
  • MSHA ID, 
  • Mine name. 

…and different units of measure.

  • Fuel quantity will now be reported in tons or barrels instead of thousand tons and thousand barrels.  Also, the reporting units for Btu content of fuels have changed (see Unit Converter .xls file)
  • Some fuel codes have changed. See Table 1, page 4 of the Form EIA-923 instructions.

How will tolling agreements (a contract wherein an entity buys the plant’s fuel in exchange for electricity) be handled?
A. Unlike the policy that has been in existence, the toller (fuel purchaser) will no longer have to file this Schedule.  Instead, all data will be provided by the plant.  If the cost of the fuel cannot be obtained by the plant from the toller, this item may be left blank.

Should I include receipts of fuel that have been sent to a separate storage site?
No, only report fuel received at the plant for the purpose of producing electricity.

How can I get the mercury content of the fuel if our company does not yet test for it?
The mercury content will be specified in the coal purchase contract.

Will cost data be kept confidential?
All commodity cost data will be protected and published only in the aggregate.  Delivered cost data from nonregulated plants will be protected and published only in the aggregate.  Delivered cost data from regulated plants will be released to the public approximately ## months after the monthly reporting deadline.

What if our company had a waiver and was not required to report on the FERC Form 423?
These plants are required to report cost and quality of fuels receipts on the Form
