FAQ

What work fits NAICS 221121?
  • Provision of 24/7 transmission system operator staffing for real-time dispatch, switching order execution, and congestion management in a control center environment.
  • SCADA, telemetry, and phasor integration projects linking remote terminal units to a system control center for real-time monitoring and control of transmission assets.
  • Contingency, load-flow, and dynamic stability studies to establish operational limits and emergency procedures for bulk transmission corridors.
  • Outage coordination and switching plan execution between transmission owners to restore service and manage transmission constraints.
When is NAICS 221121 a weak fit?
  • Electric power generation facilities: missing generation asset ownership and production dispatch responsibilities focused on generation output rather than transmission control.
  • Local distribution system maintenance and line crews: missing high-voltage bulk transmission scope and system-level operational control duties.
  • Transmission equipment manufacturing or substation construction: missing ongoing grid operations, real-time dispatch, and control center responsibilities intrinsic to this NAICS.
What solicitation language points to NAICS 221121?
  • Labor categories listed as Transmission System Operator, Grid Control Room Operator, or Transmission Dispatch Technician.
  • Scope requires SCADA/EMS integration, telemetry feeds, phasor data, or real-time RTU communications into a central control center.
  • Deliverables include switching orders, outage coordination logs, load-flow and stability study reports, or real-time dispatch logs.
