FAQ

What work fits NAICS 221330?
  • Provide, operate, and maintain a multi-customer central plant that generates and supplies metered steam to multiple buildings through a distribution main and issues consumption bills to customers.
  • Deliver chilled water under a thermal energy sales arrangement, controlling temperature and flow at delivery vaults and metering each customer point for billed consumption.
  • Supply temporary bulk steam or hot water during facility outages by tying mobile boilers into the site's distribution mains and providing metered delivery.
  • Operate metering, billing, and customer service for a centralized steam or chilled water utility, including distribution-main maintenance and recordkeeping of delivered thermal quantities.
When is NAICS 221330 a weak fit?
  • HVAC installation and repair contractors: installs or services single-building HVAC equipment but does not supply bulk thermal energy through a multi-customer distribution network and metered sales.
  • Manufacture of boilers and chillers: production of heating or cooling machinery is equipment manufacturing, lacking the bulk delivery, metering, and customer-billing elements of thermal-energy supply.
  • Single-building facilities operations: operating a mechanical plant that serves only one building without a formal distribution mains network or multi-customer thermal energy sales is outside this scope.
What solicitation language points to NAICS 221330?
  • Scope requires metered thermal energy delivery with specified temperature, pressure, or chilled-water delta-T at multiple delivery points and billing by consumption.
  • Contract deliverables include operation and maintenance of central plant and distribution mains, meter calibration records, and monthly customer billing statements.
  • Evaluation criteria reference continuity of supply, distribution-main leak detection and repair, and demonstrated capacity to meet peak thermal loads at delivery points.
