Annual time series of flue gas desulfurization (FGD) operation and maintenance expenses at generation facilities.
- Most-recent data:
2024
- Processing:
Data has been cleaned but not tidied/normalized. Published only temporarily and may be removed without notice.
- Source:
EIA Form 923 -- Power Plant Operations Report (Schedule 8C)

Usage Warnings
Some years use a slightly different data definition.
Additional Details
From 2008-2011 this table also reported operational characteristics that are now reported in 923 Air Emissions Control Info.
Note: This table has been cleaned, but not harvested with other EIA 923 or 860 data. The same variables present in this table may show up in other _core tables in other years. Once this table has been harvested, it will be removed from the PUDL database.
Columns
Date reported.
The unique six-digit facility identification number, also called an ORISPL, assigned by the Energy Information Administration.
Sulfur dioxide control identification number. This ID is not a unique identifier.
Annual operation and maintenance expenditures for feed materials and chemicals for flue gas desulfurization equipment, excluding electricity.
Annual operation and maintenance expenditures for labor and supervision of flue gas desulfurization equipment, excluding electricity.
Annual operation and maintenance expenditures for land acquisition for flue gas desulfurization equipment, excluding electricity.
Annual operation and maintenance expenditures for maintenance, materials and all other costs of flue gas desulfurization equipment, excluding electricity
Annual operation and maintenance expenditures for waste disposal, excluding electricity.
Annual total cost of operation and maintenance expenditures on flue gas desulfurization equipment, excluding electricity
Indicates whether or not a plant has a flue gas desulfurization control unit.
Operating status code for flue gas desulfurization equipment.
Number of hours the flue gas desulfurization equipment was in operation during the year.
Electric power consumed by the flue gas desulfurization unit (in MWh).
Quantity of flue gas desulfurization sorbent used, to the nearest 100 ton.
The tested efficiency for the removal of sulfur dioxide at 100 percent load. If not tested at 100 percent load, then the load at which the test was conducted is included as a comment on Schedule 9. If no test was conducted, the test date and tested efficiency field should be blank. Ranges from 0 to 1.
Sulfur dioxide removal efficiency, based on the annual operating factor, which is defined as annual fuel consumption (MMBTU) divided by the product of the boiler design firing rate (MMBTU per hour) and hours of operation per year.When actual data are not available, estimates are provided based on equipment design performance specifications. Ranges from 0 to 1.
Date of most recent test for sulfur dioxide removal efficiency.
Maturity of the source data published by EIA that is reflected in this record. EIA releases data incrementally over time, including monthly updates, annual year-to-date updates, provisional early releases of annual data, and final annual release data that is not expected to change further. Records sourced from multiple upstream EIA datasets may have no well defined data maturity. Records whose values have been inferred within PUDL will also have no data maturity.
