213114 Support Activities for Metal Mining This U.S. industry comprises establishments primarily engaged in providing support activities (except geophysical surveying and mapping, site preparation, construction, and transportation activities), on a contract or fee basis, for the mining and quarrying of metallic minerals and for the extraction of metal ores. Exploration for these minerals is included in this industry. Exploration services include traditional prospecting methods, such as taking core samples and making geological observations at prospective sites.
213115 Support Activities for Nonmetallic Minerals (except Fuels) Mining This U.S. industry comprises establishments primarily engaged in providing support activities, on a contract or fee basis, for the mining and quarrying of nonmetallic minerals (except fuel) and for the extraction of nonmetallic minerals (except geophysical surveying and mapping, site preparation, construction, and transportation activities). Exploration for these minerals is included in this industry. Exploration services include traditional prospecting methods, such as taking core samples and making geological observations at prospective sites.
22 Utilities The Utilities sector comprises establishments engaged in the provision of the following utility services: electric power, natural gas, steam supply, water supply, and sewage treatment and disposal. Within this sector, the specific activities associated with the utility services provided vary by utility: electric power includes generation, transmission, and distribution; natural gas includes distribution; steam supply includes provision and/or distribution; water supply includes treatment and distribution; and sewage removal includes collection, treatment, and disposal of waste through sewer systems and sewage treatment facilities.
221 Utilities Industries in the Utilities subsector provide electric power, natural gas, steam supply, water supply, and sewage treatment and disposal 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 This U.S. industry comprises establishments primarily engaged in operating hydroelectric power generation facilities. These facilities use water power to drive a turbine and produce electric energy. The electric energy produced in these establishments is provided to electric power transmission systems or to electric power distribution systems.
221112 Fossil Fuel Electric Power Generation This U.S. industry comprises establishments primarily engaged in operating fossil fuel powered electric power generation facilities. These facilities use fossil fuels, such as coal, oil, or gas, in internal combustion or combustion turbine conventional steam process to produce electric energy. The electric energy produced in these establishments is provided to electric power transmission systems or to electric power distribution systems.
221113 Nuclear Electric Power Generation This U.S. industry comprises establishments primarily engaged in operating nuclear electric power generation facilities. These facilities use nuclear power to produce electric energy. The electric energy produced in these establishments is provided to electric power transmission systems or to electric power distribution systems.
221114 Solar Electric Power Generation This U.S. industry comprises establishments primarily engaged in operating solar electric power generation facilities. These facilities use energy from the sun to produce electric energy. The electric energy produced in these establishments is provided to electric power transmission systems or to electric power distribution systems.
