Industries in the Utilities subsector provide electric power, natural gas, steam supply, water supply, and sewage removal through a permanent infrastructure of lines, mains, and pipes. Establishments are grouped together based on the utility service provided and the particular system or facilities required to perform the service.
2211 Electric Power Generation, Transmission and Distribution
This industry group comprises establishments primarily engaged in generating, transmitting,
and/or distributing electric power. Establishments in this industry group may perform one or more
of the following activities: (1) operate generation facilities that produce electric energy; (2)
operate transmission systems that convey the electricity from the generation facility to the
distribution system; and (3) operate distribution systems that convey electric power received
from the generation facility or the transmission system to the final consumer.
22111 Electric Power Generation
This industry comprises establishments primarily engaged in operating electric power generation
facilities. These facilities convert other forms of energy, such as water power (i.e.,
hydroelectric), fossil fuels, nuclear power, and solar power, into electrical energy. The
establishments in this industry produce electric energy and provide electricity to transmission
systems or to electric power distribution systems.
221111 Hydroelectric Power Generation
221112 Fossil Fuel Electric Power Generation
221113 Nuclear Electric Power Generation
221119 Other Electric Power Generation
Cross-References. Establishments primarily engaged in operating trash incinerators that also generate electricity are classified in
Industry 56221, Waste Treatment and Disposal.
22112 Electric Power Transmission, Control, and Distribution
This industry comprises establishments primarily engaged in operating electric power transmission
systems, controlling (i.e., regulating voltages) the transmission of electricity, and/or
distributing electricity. The transmission system includes lines and transformer stations. These
establishments arrange, facilitate, or coordinate the transmission of electricity from the
generating source to the distribution centers, other electric utilities, or final consumers. The
distribution system consists of lines, poles, meters, and wiring that deliver the electricity to
final consumers.
