What is NAICS 221
NAICS code 221 covers the Utilities subsector, which encompasses industries engaged in providing essential services such as electric power, natural gas, steam supply, water supply, and sewage treatment and disposal. These services are delivered through a permanent infrastructure of lines, mains, and pipes that support residential, commercial, and industrial customers. Businesses operating in this sector include electric power generation and distribution companies, natural gas distribution firms, water supply companies, and sewage treatment facilities. The sector plays a critical role in maintaining public health, safety, and economic stability by ensuring reliable utility services.
Government agencies contract for these utility services to support federal operations, military bases, public facilities, and community infrastructure. Reliable utilities are vital to mission-critical activities, disaster recovery, and sustainable development programs. Additionally, government contracts often focus on upgrading infrastructure, expanding service areas, and integrating renewable and smart technologies to improve efficiency and environmental compliance. The Utilities subsector is thus central to public service delivery and infrastructure modernization efforts supported through government procurement.
